Role of intravascular ultrasound for the technical assessment of endovascular reconstruction of the aortic bifurcation. J Vasc Surg 2024; 80:441-450. [PMID: 38485070 DOI: 10.1016/j.jvs.2024.03.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2024] [Revised: 02/28/2024] [Accepted: 03/05/2024] [Indexed: 04/09/2024]
Abstract
OBJECTIVE The aim of this study was to evaluate the role of intravascular ultrasound (IVUS) for the technical assessment of kissing stents (KSs) and covered endovascular reconstruction of the aortic bifurcation (CERAB) in the treatment of aortoiliac obstructive disease involving the aortic bifurcation. METHODS We conducted a single-center retrospective review of patients undergoing endovascular treatment of severe aorto-iliac obstructive disease (2019-2023). IVUS was performed in patients treated by KSs or CERAB according to preoperative indications, in cases of moderate/severe calcifications, mural thrombus, total occlusions, and lesion extension towards the proximity of renal or hypogastric arteries. Indications for IVUS-guided intraoperative revisions were residual stenosis or compression >30%, incomplete stent-to-wall apposition, or flow-limiting dissection at the landing site. Follow-up assessment was performed at 6 and 12 months, and then yearly. Thirty-day outcomes and 2-year patency rates were evaluated. Logistic regression was used to identify factors associated with significant technical defects detected by IVUS needing intraoperative revision. RESULTS IVUS was used for the technical assessment of 102 patients treated by KSs (n = 57; 56%) or CERAB (n = 45; 44%) presenting with severe intermittent claudication (39%), rest pain (39%), or ischemic tissue loss (25%). Twenty-nine significant technical defects were identified by IVUS in 25 patients (25%) who then had successful intraoperative correction by additional ballooning (n = 23; 80%) or stenting (n = 6; 20%). Patients with a severely calcified chronic total occlusion (odds ratio, 1.85; 95% confidence interval, 1.01-5.27; P = .044) or severely calcified narrow aortic bifurcation with <12 mm diameter (odds ratio, 2.34; 95% confidence interval, 1.10-8.64; P = .032) were at increased risk for IVUS-guided intraoperative revision. There were no postoperative deaths and no major adverse events. Two-year primary patency was 100%. CONCLUSIONS IVUS was used for the technical assessment of KSs/CERAB in a selected cohort of patients with severe aorto-iliac obstructive disease. This allowed the identification and intraoperative correction of a significant technical defect not detected by completion angiogram in one-quarter of patients, achieving optimal 2-year results. IVUS assessment of KSs/CERAB may be considered especially in patients with a calcified total occlusion or narrow aortic bifurcation.

Abstract
PURPOSE To examine the association between acute kidney injury (AKI) severity and duration with cardiovascular mortality, following endovascular treatment of femoropopliteal disease, and whether it is AKI in itself that confers an increased risk of cardiovascular mortality. METHODS A retrospective analysis of prospectively collected data obtained between 2014 and 2019 from 3 vascular centers. Renal function was followed up for a minimum of 90 days. Electronic records were queried to establish a cause of death, where applicable. Patients were excluded if unable to provide written informed consent or if presenting with acute limb ischemia. Primary outcomes were the hazard ratios for cardiovascular death (AKI patients vs no AKI; no AKI vs stage 1 AKI vs stage 3 AKI; and no AKI vs transient AKI vs established AKI). Propensity score-matched analysis was used to establish whether developing AKI, in patients with similar demographics and procedural characteristics, is associated with a higher risk of cardiovascular death. RESULTS Overall 239 patients developed AKI, and this was associated with an increased risk of cardiovascular mortality (hazard risk [HR]: 4.3, 95% confidence intervals [CIs]: 2.1-6.8, pairwise comparison p value=0.006]. This was dependent on the severity of the AKI stage (HR 5.4, 95% CI: 2.4-7.3, pairwise comparison p value=0.01) and duration (HR 4.2, 95% CI: 2.3-6.2, pairwise comparison p value=0.04). The propensity score-matched analysis showed that even when patients are matched for comorbidity and procedural characteristics, AKI confers an increased risk of mortality (p=0.04). CONCLUSIONS Acute kidney injury is common after femoropopliteal endovascular therapy. It confers an increased risk of long-term cardiovascular mortality, which is still present when renal decline is transient, and highest for patients with established decline in renal function. CLINICAL IMPACT This is the first study in the setting of peripheral arterial disease to show that acute kidney injury has an adverse effect on cardiovascular mortality, in the long-term, that is dependent on its severity, and present even when the AKI is transient. We have also shown that this difference in cardiovascular mortality becomes more pronounced from the medium-term, and thus closer follow-up of these patients is required.

[PMID: 39067849 DOI: 10.1016/j.avsg.2024.06.032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2024] [Revised: 05/02/2024] [Accepted: 06/02/2024] [Indexed: 07/30/2024]
Abstract
INTRODUCTION Acute Limb Ischemia (ALI) is a morbid and deadly diagnosis. However, existing epidemiologic studies describing ALI predate the introduction of the Affordable Care Act in 2010 and direct oral anticoagulants in 2011. Thus, we synergized the National Inpatient Sample (NIS) and United States (U.S.) Census to define contemporary trends in the incidence, treatment, and outcomes of ALI in the US. METHODS We included emergent admissions of adults with primary diagnosis of lower extremity ALI in survey-weighted NIS data (2005-2020). Mann-Kendal trend test evaluated ALI incidence (primary outcome), anticoagulation usage, insurance coverage, revascularization type, and in-hospital amputation/death. Multivariable logistic regression quantified covariate associations with in-hospital amputation/death. RESULTS Of 582,322,862 estimated hospitalizations in the NIS, 227,440 met inclusion criteria (mean age 68.80 years, 49.94% women, 76.66% White). ALI incidence peaked in 2006 (7.16/100,000 person-years) but has declined since 2015 to 4.16/100,000 person-years in 2020 (ptrend=.008). Endovascular revascularization, anticoagulation, and Medicaid coverage increased, while self-pay insurance decreased (ptrend<.05). Amputation rates significantly decreased from 8.04% to 6.54% (ptrend=.01) while death rate remained at 5.59% (ptrend=.16) over the study period. Pre-hospitalization anticoagulation was associated with decreased amputation (aOR=0.74 [95%CI 0.65-0.84]) and death (aOR=0.50 [95%CI 0.43-0.57]). When controlling for covariates, women had a higher risk of death (aOR=1.17 [95%CI 1.07-1.27], p<.0001), while Black patients had a higher risk of amputation (aOR=1.24 [95%CI 1.10-1.41], p<.0001). CONCLUSIONS Our U.S. population based epidemiological study demonstrates that ALI incidence and in-hospital amputation rates are decreasing, while mortality remains unchanged. We further highlight the ongoing need for ALI investigation specifically as it relates to access to care, antithrombotic therapy use, treatment strategy, and strategies to combat gender and racial disparities.

Ann Vasc Surg 2024; 109:35-46. [PMID: 39019254 DOI: 10.1016/j.avsg.2024.06.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2024] [Revised: 05/10/2024] [Accepted: 06/05/2024] [Indexed: 07/19/2024]
Abstract
BACKGROUND The treatment of chronic limb-threatening ischemia (CLTI) involves a broad spectrum of therapies including many new and emerging techniques. To standardize the results of studies examining this pathology and to allow critical analysis and comparison between studies, the Society for Vascular Surgery (SVS) recommended reporting standard guidelines for the endovascular management of CLTI in 2016. Research studies that do not adhere to complete reporting standards are often more ambiguous in impact and external validity, leading to bias and misinformation that has potentially damaging effects on clinical decision-making. We thus sought to examine adherence to and factors associated with noncompliance with these recommended guidelines. METHODS A literature database search was conducted to include all clinical trials, randomized controlled trials, and retrospective comparative studies written in English examining the endovascular treatment of peripheral artery disease (PAD)/CLTI from January 2020 to August 2022. Systematic reviews, case reports, and meta-analysis were excluded. The manuscripts were reviewed for adherence with the SVS guidelines (overall and by guideline subcategories based on demographics, treatment methods, and outcomes), and factors associated with this adherence were determined. These data were used to calculate descriptive and comparative statistics. RESULTS Fifty-four manuscripts were identified from this time frame. On average, articles reviewed reported on 42.0% of the SVS reporting standards (range, 25.0-65.2%, Fig 1) with 74.1% of articles (n = 40) not adhering to at least 50.0% of the standards. Manuscripts most completely followed guidelines regarding "patient factors" and were least likely to demonstrate adherence to the description of CLTI and study complications. Within the guideline subcategories, complete adherence to guidelines was not demonstrated in any manuscript in stent trials, disease outcome measures, technical outcome measures, patient factors and critical limb ischemia description, and complete adherence rates within the other subcategories was low (range, 5.6-18.6%). Studies conducted within the United States and those with industry sponsorship were more likely to adhere to >50% of the reporting standards (P < 0.05). Journal impact factor, year of publication, and number of authors had no correlation to the percent adherence to guidelines in specific categories or adherence overall. CONCLUSIONS Adherence to reporting standard guidelines for endovascular treatment of lower extremity PAD specifically outlined by the SVS is suboptimal regardless of the quality of the journal the research is published in. Increasing adherence to reporting standards to provide a framework for comparison of studies across techniques used should be prioritized by authors, journal editors, and vascular societies.

Abstract
OBJECTIVE To report the cost of target lesion revascularisation procedures (TLR) for femoropopliteal peripheral artery disease (PAD) following stenting, from a healthcare payer's perspective. METHODS European multicentre study involving consecutive patients requiring femoropopliteal TLR (January 2017 - December 2021). The primary outcome was overall cost (euros) associated with a TLR procedure from presentation to discharge. Exact costs per constituent, clinical characteristics, and early outcomes were reported. RESULTS This study included 482 TLR procedures (retrospectively, 13 hospitals, six countries): 56% were female, mean age was 75 ± 2 years, 61% were Rutherford class 5 or 6, 67% had Tosaka class 3 disease, and 16% had common femoral or iliac involvement. A total of 52% were hybrid procedures and 6% involved open surgery only. Technical success was 70%, 30 day mortality rate was 1%, and the 30 day major amputation rate was 4%. Most costs were for operating time during the TLR (healthcare professionals' salaries, indirect and estate costs), with a mean of: €21 917 ± €2 110 for all procedures; €23 337 ± €8 920 for open procedures; €12 903 ± €3 108 for endovascular procedures; and €22 806 ± €3 977 for hybrid procedures. In a regression analysis, procedure duration was the main parameter associated with higher overall TLR costs (coefficient, 2.77; standard error, 0.88; p < .001). The mean cost per operating minute of TLR (indirect, estate costs, all salaried staff present included) was €177 and the mean cost per night stay in hospital (outside intensive care unit) was €356. The mean cost per overnight intensive care unit stay (minimum of 8 hours per night) was €1 193. CONCLUSION The main driver of the considerable peri-procedure costs associated with femoropopliteal TLR was procedure time.

Predictors of major adverse lower limb events in patients with tissue loss secondary to critical limb-threatening ischemia. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2024; 64:34-41.

Abstract
BACKGROUND Chronic limb-threatening ischemia (CLTI) is the end-stage of peripheral arterial disease (PAD) posing a high risk for limb loss and mortality. This study aims to evaluate and list possible predictors of major adverse limb events (MALEs) in CLTI patients with tissue loss. METHODS This retrospective study included all Rutherford-Becker stage 5 or 6 patients who required foot debridement and revascularization in our department from January 2016 to December 2018. The limbs were classified according to the TASC II, GLASS and WiFI grading systems. The primary composite outcome was MALEs at 2 years. The secondary outcomes included all-cause mortality, primary patency, freedom from reintervention, and major amputation. Kaplan-Meier estimates were used to determine the event rates, and Cox proportional hazards model with the index MALE as a time-dependent covariate was used to search for MALEs predictors. RESULTS Of 241 included patients, 19 underwent open surgeries (7.9 %) 207 had endovascular interventions (85.9 %) and 15 required a hybrid approach (6.2 %). On univariate analysis, patients who experienced MALEs (n = 111) more often required hemodialysis (25 vs 15; p = .02), presented with more complex lesions (TASC D on femoropopliteal (p = .05) or below the knee (BTK) arteries (p = .006) with increasing infra-inguinal GLASS Stage (p < .0001)), a history of index limb open (p = .009) or endovascular (p = .049) revascularization, an occluded tibial artery (p = .002 for the posterior tibial and p = .052 for the anterior tibial), or a "desert foot" (p = .02). The CRP level was also higher at admission (p = .001). Technical success of BTK revascularization significantly reduced MALEs (p < .0001) along with the number of patent BTK vessels (p = .0007). Independent predictors of MALEs included hemodialysis (HR = 2.00; 95%CI: 1.14 to 3.39), pulsatile arterial pressure (HR = 1.01; 95%CI: 1.00 to 1.03) and the infra-inguinal GLASS Stage (HR = 2.50; 95%CI: 1.17 to 5.82). We could not correlate our results with the WiFI scores for amputation risk and revascularization benefit. CONCLUSION For patients with CLTI at the stage of trophic disorders, with or without a history of index limb revascularization, the GLASS successfully predicted MALEs. Hemodialysis and high pulsatile arterial pressure increased the risk of MALEs. The WiFI score did not demonstrate its interest in this subgroup of patients.

Abstract
OBJECTIVE The aim of this study was to investigate whether intimal arterial calcification (IAC) and medial arterial calcification (MAC) are correlated with the various clinical outcomes following endovascular therapy (EVT) for peripheral arterial disease (PAD). METHODS This single-center retrospective study comprised 154 consecutively hospitalized individuals with PAD who underwent EVT for de novo femoral-popliteal calcific lesions from January 2016 to July 2021. The predominant calcification patterns of IAC and MAC were assessed using a semi-quantitative computed tomography scoring system. The Kaplan-Meier method and Cox regression were conducted to evaluate the correlations between calcification patterns and medium- to long-term outcomes. RESULTS The distribution of calcification patterns was as follows: IAC in 111 patients (72%) and MAC in 43 patients (28%). No remarkable variation was noted between the IAC and MAC groups regarding age (P = .84) and gender (P = .23). The MAC group indicated lower rates of 4-year primary patency, assisted primary patency, secondary patency, and amputation-free survival (AFS) compared with the IAC group (24% ± 7% vs 40% ± 6%; P = .003; 30% ± 8% vs 51% ± 6%; P = .001; 51% ± 8% vs 65% ± 5%; P = .004; and 43% ± 9% vs 76% ± 5%; P < .001, respectively). There was no significant difference in the rate of freedom from clinically driven target lesion revascularization between the MAC and IAC groups (63% ± 10% vs 73% ± 5%; P = .26). Stepwise multivariable Cox regression analysis demonstrated that MAC was associated with poor patency (hazard ratio, 1.81; 95% confidence interval, 1.12-2.93; P = .016) and AFS (hazard ratio, 2.80; 95% confidence interval, 1.52-5.16; P = .001). CONCLUSIONS Compared with IAC, MAC is independently associated with lower medium- to long-term patency and AFS after EVT for de novo femoral-popliteal occlusive lesions.

Abstract
PURPOSE Although thrombolysis obliterans (TAO) has been recognized for more than a century, there is no optimal treatment for this disease. The aim of this report was to compare the short-term efficacies of catheter-directed thrombolysis (CDT), percutaneous transluminal angioplasty (PTA) and CDT+PTA in treating TAO disease. METHOD Consecutive patients with TAO treated at Ganzhou People's Hospital between 2012 and 2022 were included in this retrospective study. According to the information provided in the medical records, endovascular procedures included CDT, PTA or CDT+PTA. One-year follow-up outcomes of the patients with TAO who underwent endovascular procedures were compared. The primary outcome was major adverse limb event (MALE) and the secondary outcomes were the technical success, complications, ABI at 1 week after surgery and minor amputation. RESULTS Sixty-nine patients with TAO were assessed for inclusion in our single-center study from 2012 to 2022 and received endovascular procedures. Among them, 22 patients underwent CDT, 21 patients underwent PTA, and 26 patients underwent PTA+CDT. The one-year follow-up revealed significant differences in the MALE-free survival rates among the three groups, particularly between the CDT group and the PTA+CDT group (the hazard ratio (HR) for MALE-free survival was 0.173, 95% CI [0.050-0.599], p = 0.006). The technical success rates of the three groups were 63.6%, 90.5%, and 92.3%, respectively. There were differences in the ABI at one week after surgery among the three groups. CONCLUSIONS Endovascular procedures are effective for TAO in the short term. The effectiveness of CDT alone is suboptimal; combining CDT with PTA achieves the most favorable endovascular treatment outcome; while the effectiveness of PTA falls in between these two procedures.

Campbell DB, Gutta G, Sobol CG, Atway SA, Haurani MJ, Chen XP, Rowe VL, Stacy MR, Go MR. How multidisciplinary clinics may mitigate socioeconomic barriers to care for chronic limb-threatening ischemia. J Vasc Surg 2024:S0741-5214(24)01212-6. [PMID: 38906429 DOI: 10.1016/j.jvs.2024.05.033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2024] [Revised: 05/13/2024] [Accepted: 05/15/2024] [Indexed: 06/23/2024]
Abstract
OBJECTIVE Although multidisciplinary clinics improve outcomes in chronic limb-threatening ischemia (CLTI), their role in addressing socioeconomic disparities is unknown. Our institution treats patients with CLTI at both traditional general vascular clinics and a multidisciplinary Limb Preservation Program (LPP). The LPP is in a minority community, providing expedited care at a single facility by a consistent team. We compared outcomes within the LPP with our institution's traditional clinics and explored patients' perspectives on barriers to care to evaluate if the LPP might address them. METHODS All patients undergoing index revascularization for CLTI from 2014 to 2023 at our institution were stratified by clinic type (LPP or traditional). We collected clinical and socioeconomic variables, including Area Deprivation Index (ADI). Patient characteristics were compared using χ2, Student t, or Mood median tests. Outcomes were compared using log-rank and multivariable Cox analysis. We also conducted semi-structured interviews to understand patient-perceived barriers. RESULTS From 2014 to 2023, 983 limbs from 871 patients were revascularized; 19.5% of limbs were treated within the LPP. Compared with traditional clinic patients, more LPP patients were non-White (43.75% vs 27.43%; P < .0001), diabetic (82.29% vs 61.19%; P < .0001), dialysis-dependent (29.17% vs 13.40%; P < .0001), had ADI in the most deprived decile (29.38% vs 19.54%; P = .0061), resided closer to clinic (median 6.73 vs 28.84 miles; P = .0120), and had worse Wound, Ischemia, and foot Infection (WIfI) stage (P < .001). There were no differences in freedom from death, major adverse limb event (MALE), or patency loss. Within the most deprived subgroup (ADI >90), traditional clinic patients had earlier patency loss (P = .0108) compared with LPP patients. Multivariable analysis of the entire cohort demonstrated that increasing age, heart failure, dialysis, chronic obstructive pulmonary disease, and increasing WIfI stage were independently associated with earlier death, and male sex was associated with earlier MALE. Ten traditional clinic patients were interviewed via convenience sampling. Emerging themes included difficulty understanding their disease, high visit frequency, transportation barriers, distrust of the health care system, and patient-physician racial discordance. CONCLUSIONS LPP patients had worse comorbidities and socioeconomic deprivation yet had similar outcomes to healthier, less deprived non-LPP patients. The multidisciplinary clinic's structure addresses several patient-perceived barriers. Its proximity to disadvantaged patients and ability to conduct multiple appointments at a single visit may address transportation and visit frequency barriers, and the consistent team may facilitate patient education and improve trust. Including these elements in a multidisciplinary clinic and locating it in an area of need may mitigate some negative impacts of socioeconomic deprivation on CLTI outcomes.

Covered Stents Versus Bare Metal Stents in the Treatment of Aorto-iliac Disease: A Systematic Review and Individual Participant Data Meta-analysis. Eur J Vasc Endovasc Surg 2024:S1078-5884(24)00480-5. [PMID: 38876369 DOI: 10.1016/j.ejvs.2024.06.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2024] [Revised: 05/12/2024] [Accepted: 06/06/2024] [Indexed: 06/16/2024]
Abstract
OBJECTIVE To assess the comparative safety and efficacy of covered stents (CS) and bare metal stents (BMS) in the endovascular treatment of aorto-iliac disease in patients with peripheral arterial disease. DATA SOURCES A systematic review was conducted adhering to the PRISMA 2020 and PRISMA for Individual Participant Data 2015 guidelines. REVIEW METHODS A search of PubMed, Scopus, and Web of Science for articles published by December 2023 was performed. The primary endpoint was primary patency. Certainty of evidence was assessed via the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework. RESULTS Eleven studies, comprising 1 896 patients and 2 092 lesions, were included. Of these, nine studies reported on patients' clinical status, with 35.5% classified as Rutherford 4 - 6. Overall primary patency for CS and BMS at 48 months was 91.2% (95% confidence interval [CI] 84.1 - 99.0%) (GRADE, moderate) and 83.5% (95% CI 70.9 - 98.3%) (GRADE, low). The one stage individual participant data meta-analyses indicated a significant risk reduction for primary patency loss favouring CS (hazard ratio [HR] 0.58, 95% CI 0.35 - 0.95) (GRADE, very low). The 48 month primary patency for CS and BMS when treating TransAtlantic Inter-Society Consensus (TASC) C and D lesions was 92.4% (95% CI 84.7 - 100%) (GRADE, moderate) and 80.8% (95% CI 64.5 - 100%) (GRADE, low), with CS displaying a decreased risk of patency loss (HR 0.39, 95% CI 0.27 - 0.57) (GRADE, moderate). While statistically non-significant differences were identified between CS and BMS regarding technical success, 30 day mortality rate, intra-operative and immediate post-operative procedure related complications, and major amputation, CS displayed a decreased re-intervention risk (risk ratio 0.59, 95% CI 0.40 - 0.87) (GRADE, low). CONCLUSION This review has illustrated the improved patency of CS compared with BMS in the treatment of TASC C and D lesions. Caution is advised in interpreting overall primary patency outcomes given the substantial inclusion of TASC C and D lesions in the analysis. Ultimately, both stent types have demonstrated comparable safety profiles.

Abstract
OBJECTIVES To determine the influence that the number of patent crural run-off vessels has on short- and mid-term outcomes following femoro-popliteal bypass. METHODS All patients undergoing index femoro-popliteal bypass grafting between 2013 and 19 at our unit were included. Preoperative imaging was used to stratify patients into cohorts with either one or ≥2 patent run-off vessels. Primary outcomes measures included bypass patency and limb salvage rates at one and 3 years post-operatively. Survival analysis was performed using Kaplan-Meier curves and Logrank test. RESULTS 147 bypasses performed on 143 patients were included. 24 patients had one-vessel run-off and 123 had ≥2 vessels patent. Patients with one-vessel run-off had a higher proportion of emergency admissions (54% vs 41%) and diabetes (42% vs 31%). 31% of patients underwent diagnostic angiogram imaging in addition to having duplex ultrasound and/or computed tomography angiography. There were no significant differences in primary, primary-assisted or secondary patency rates between the cohorts at 12 or 36 months. Limb salvage rates were significantly higher amongst those with ≥2 vessel run-off at 12 (86% vs 71%, p = 0.03) and 36 (85% vs 71%, p = 0.04) months. For those with occluded grafts, a higher proportion of patients with ≥2 vessel run-off subsequently had an attempt at redo bypass grafting. CONCLUSIONS Femoro-popliteal bypass is a reasonable treatment option for patients with one-vessel run-off. However, whilst patency rates are comparable, clinicians should be aware of the lower successful limb salvage rates for patients with one patent vessel (especially those presenting with tissue loss).

Abstract
OBJECTIVE We compared the efficacy of percutaneous deep venous arterialization (pDVA) in patients with no-option chronic limb-threatening ischemia in the hospital vs in office-based laboratory (OBL) settings. METHODS A retrospective chart review was performed of all patients who underwent pDVA using off-the-shelf devices from January 2018 to March 2023 in a hospital and an OBL. We identified 73 eligible patients, 41 from a hospital setting (59% male; median age, 72 years; interquartile range, 18 years) and 32 from an OBL setting (59% males; 67 years; interquartile range, 16 years). All eligible patients were deemed to have no-option critical limb ischemia, had at least one patent proximal tibial artery available for the creation of an arteriovenous anastomosis, and were classified as having Rutherford classification IV or higher peripheral arterial disease. Patients were ineligible if classified as Rutherford classification III or lower, had active infection, did not have at least one appropriate venous target, and/or had rapidly progressing wounds requiring immediate major amputation. The primary outcome was major amputation-free survival (AFS). Secondary outcomes included technical success, limb salvage, survival, primary patency, reintervention rate, adverse events, and partial and complete wound healing. Outcomes were evaluated using Kaplan-Meier method, log-rank, and two-stage procedure tests. RESULTS Technical success was achieved in 70 patients (96%) with 1 hospital (2.4%) and 2 OBL (6.3%) patients lost to follow-up. Major AFS estimates at 6 months, 1 year, and 2 years were 51.4%, 40.4%, and 30.2% in the hospital group and 69.4%, 54.0%, and 49.5% in the OBL group, respectively. Partial wound healing estimates at 6 months, 1 year, and 2 years were 27.5%, 71.7%, and 81.2% in the hospital group and 62.7% at all time points in the OBL group. Complete wound healing estimates at 6 months, 1 year, and 2 years were 6.7%, 33.3%, and 33.3% in the hospital group and 5.3%, 37.7%, and 41.6% in the OBL group, respectively. There was no significant difference in major AFS (P = .13), limb salvage (P = .07), survival (P = .69), primary patency (P = .53), partial (P = .08), or complete wound healing (P = .79) between groups. Reintervention was performed in 8 hospital (20.5%) and 14 OBL (45.2%) patients. CONCLUSIONS pDVA is a feasible and safe procedure for no-option critical limb ischemia in the hospital and OBL setting without significant differences in outcomes at ≤2 years.

Abstract
OBJECTIVE To evaluate the safety and clinical outcomes of the Passeo-18 Lux drug-coated balloon (DCB) in endovascular revascularization procedures under real-world conditions in a Korean population with atherosclerotic disease of the infrainguinal arteries, including below-the-knee (BTK) arteries. MATERIALS AND METHODS Eight institutions in the Republic of Korea participated in this prospective, multicenter, single-arm, post-market surveillance study. Two hundred patients with Rutherford class 2-5 peripheral arterial disease and infrainguinal lesions suitable for endovascular treatment were competitively enrolled. Data were collected at baseline, the time of intervention, discharge, and 1-, 6-, 12-, and 24-month follow-up visits. The primary safety endpoint was freedom from major adverse events (MAE) within 6 months (except when limiting the time frame for procedure- or device-related mortality to within 30 days), and the primary effectiveness endpoint was freedom from clinically driven target lesion revascularization (CD-TLR) within 12 months after the procedure. RESULTS A total of 197 patients with 332 target lesions were analyzed. Two-thirds of the patients had diabetes mellitus, and 41.6% had chronic limb-threatening ischemia. The median target lesion length was 100 mm (interquartile range: 56-133 mm). Of the target lesions, 35.2% were occlusions, and 14.8% were located in the BTK arteries. Rate of freedom from MAE was 97.9% at 6 months, and the rate of freedom from CD-TLR was 95.0% and 92.2% at 12 and 24 months, respectively. Subgroup analysis of 43 patients and 49 target lesions involving the BTK arteries showed rate of freedom from MAE of 92.8% at 6 months and rates of freedom from CD-TLR of 88.8% and 84.4% at 12 and 24 months, respectively. CONCLUSION The results of the present study, including the BTK subgroup analysis, showed outcomes comparable to those of other DCB studies, confirming the safety and effectiveness of Passeo-18 Lux DCB in the Korean population.

Abstract
BACKGROUND Gupta Perioperative Risk for Myocardial Infarction or Cardiac Arrest (MICA) is a validated self-explanatory score applied in cardiac or noncardiac surgeries. This study aims to assess the predictive value of the MICA score for cardiovascular events after aortoiliac revascularization. METHODS This prospective cohort underwent elective aortoiliac revascularization between 2013 and 2021. Patients' demographic, clinical characteristics, and outcomes were registered. The patients were divided into 2 groups according to the MICA score using optimal binning. Survival analysis to test for time-dependent variables and multivariate Cox regression analysis for independent predictors were performed. RESULTS This study included 130 patients with a median follow-up of 55 months. Preoperative MICA score was ≥6.5 in 41 patients. MICA ≥6.5 presented a statistically significant association, with long-term occurrence of acute heart failure (HR = 1.695, 95% CI 1.208-2.379, P = 0.002), major adverse cardiovascular events (HR = 1.222, 95% CI 1.086-1.376, P < 0.001), and all-cause mortality (HR = 1.256, 95% CI 1.107-1.425, P < 0.001). Multivariable Cox regression confirmed MICA as a significant independent predictor of long-term major adverse cardiovascular events (aHR = 1.145 95% CI 1.010-1.298, P = 0.034) and all-cause mortality (aHR = 1.172 95% CI 1.026-1.339, P = 0.020). CONCLUSIONS The MICA score is a quick, easy-to-obtain, predictive tool in identifying patients with a higher risk of postaortoiliac revascularization cardiovascular events, such as acute heart failure, major adverse cardiovascular events, and all-cause mortality. Additional research for the validation of the MICA score in the context of aortoiliac revascularization and specific interventions is necessary.

Intraoperative Transit-Time Flow as a Predictor of Failure after Infrainguinal Revascularization with Heparin-Bonded Expanded Polytetrafluoroethylene Graft. Ann Vasc Surg 2024; 106:273-283. [PMID: 38821469 DOI: 10.1016/j.avsg.2024.04.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2024] [Revised: 04/03/2024] [Accepted: 04/03/2024] [Indexed: 06/02/2024]
Abstract
BACKGROUND The heparin-bonded expanded polytetrafluoroethylene (He-ePTFE) conduit is an option for patients requiring infrainguinal revascularization (iIR), but the risk of failure may be unpredictable, especially in cases with poor run-off. Intraoperative transit-time flow (TTF) provides an automated and quantitative analysis of flow and may serve as an adjunct evaluation during surgical revascularization. The aim of this study was to assess TTF in patients undergoing iIR with He-PTFE at 3 referral hospitals and to establish a predictive flow threshold for graft occlusion. METHODS A prospective registry initiated in 2020 enrolled patients undergoing iIR using He-PTFE for critical limb ischemia or severe claudication, and TTF measurement was analyzed. Preoperative assessments of anatomical and clinical characteristics were available for all patients. The HT353 Optima Meter (Transonic Systems Inc., Ithaca, NY, USA) was used in all procedures according to a standardized protocol. The institutional ethics committee approved the study. A predictive model using receiver operating characteristic curve analysis was utilized to establish the threshold of flow, and variables were compared. Anatomical and clinical evaluation were reported according to Rutherford grade, Global Limb Anatomic System and Wound, Ischemia, and foot Infection classification. The main outcome considered was the correlation between TTF and graft occlusion. Secondary outcomes included survival, other predictors of graft occlusion, freedom from major adverse cardiovascular events, and freedom from major amputation. RESULTS Among 68 patients, 55.8% had Rutherford 5-6, 45.6% had Global Limb Anatomic System 3 and 73.5% had Wound, Ischemia, and foot Infection 3-4. Distal anastomosis was at tibial level in 23.5% and mean diameter of conduit was 6.4 mm. Basal and postoperative TTF were 27.8 ± 15.6 ml/min and 109.0 ± 53.0 ml/min, respectively. After a mean follow-up of 18 ± 13 months, 7 (10.9%) patients presented graft occlusion and 5 (7.8%) required major amputation. TTF threshold = 80 ml/min revealed a sensitivity and specificity of 81.8% (95% confidence interval 48.2-97.7) and 80.7% (95% confidence interval 68.1-90.0) respectively, and it was selected as cut-off for graft occlusion. Freedom from graft occlusion in patients with TTF >80 ml/min vs. TTF ≤80 ml/min at 6, 12, and 24 months was 95.7% (standard error (SE) = 0.030) vs. 65.5% (SE = 0.115), 95.7% (SE = 0.030) vs. 58.9% (SE = 0.120) and 90.9% (SE = 0.054) vs. 51.6% (SE = 0.126), P = 0.0003. No statistical difference in primary patency, secondary patency and limb salvage was observed. At multivariate analysis, distal anastomosis at tibial vessel (odds ratio 8.50) and TTF ≤80 ml/min (odds ratio 9.39) were independent predictors of graft occlusion. CONCLUSIONS These results suggest that TTF may serve as a valuable tool in the management of iIR. A TTF measurement of ≤80 ml/min should be regarded as a predictor of graft occlusion, prompting consideration of additional intraoperative maneuvers to enhance arterial flow. Caution should be exercised in patients requiring direct tibial artery revascularization, as it represents a predictor of failure independent of TTF levels. Larger cohorts of patients and longer follow-up periods are necessary to confirm these findings.

Abstract
BACKGROUND Infra-popliteal interventions for chronic limb-threatening ischemia (CLTI) can be impacted by the morphology of the tibial vessels. The aim of this study was to examine the impact of a novel morphology-driven classification on the outcomes of isolated tibial intervention for CLTI. METHODS A database of patients undergoing isolated tibial interventions for CLTI at a single center between 2010 and 2020 was retrospectively queried. Patients with isolated infra-popliteal disease were identified, and their anatomy was scored as present or absent for lesion calcification (1 point), target vessel diameter<3.0 mm (1 point), lesion length>300 mm (1 point), and poor pedal runoff score (1 point). Patients were then divided into 3 groups: low risk (0 or 1 points), moderate risk (2 points), and high risk (3 or 4 points). Intention to treat analysis by the patient was performed. Limb-based patency (the absence of reintervention, occlusion, critical stenosis [>70%], or hemodynamic compromise with ongoing symptoms of CLTI as it related to the patency of the preoperatively determined target artery pathway) was assessed. Patient-oriented outcomes of amputation-free survival (AFS; survival without major amputation) and freedom from major adverse limb events (MALE; above ankle amputation of the index limb or major reintervention: new bypass graft, jump/interposition graft revision) were evaluated. RESULTS 1,607 patients (55% male, average age 60 years, 3,846 vessels) underwent tibial intervention for CLTI. The majority of the patients were diabetic and of Hispanic origin. Morphologically, 27%, 31%, and 42% of the vessels were categorized as low risk, moderate risk, and high risk, respectively. There was a significant worsening of the infra-popliteal Global Limb Anatomic Staging System (GLASS) grading as the morphological risk increased. The 30-day major adverse cardiac events (MACE) were equivalent across the groups and were under the stated objective performance goal (OPG) of ≤10%. In contrast, both the 30-day MALE and the 30-day major amputations were significantly different across the groups, with the low-risk group remaining under the OPG of ≤9% and ≤4%, respectively, while the moderate risk and high risk exceeded the goal threshold. For the OPG, freedom from MALE was 60 ± 5%, 46 ± 5%, and 22 ± 9% at 5 years for low-, moderate-, and high-risk groups, respectively (mean ± standard error of the mean; P = 0.008). Overall AFS was 55 ± 5%, 37 ± 6%, and 18 ± 7% at 5 years for low-, moderate-, and high-risk groups, respectively (mean ± standard error of the mean; P = 0.003). CONCLUSIONS Tibial anatomic morphology impacts isolated tibial endovascular intervention with adverse morphology associated with poorer short- and long-term outcomes. Risk stratification based on anatomic predictors should be an additional consideration as one intervenes on infra-popliteal vessels for CLTI.

[PMID: 38815902 DOI: 10.1016/j.avsg.2024.03.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2023] [Revised: 02/27/2024] [Accepted: 03/07/2024] [Indexed: 06/01/2024]
Abstract
BACKGROUND In India, a significant scarcity of published data exists regarding chronic limb-threatening ischemia (CLTI) and its management, especially among the elderly population. CLTI, often accompanied by frailty poses a significant healthcare challenge. While endovascular interventions offer hope, there remains a dearth of outcome data for this age group. This study seeks to address this critical gap by investigating the impact of frailty on outcomes, emphasizing amputation-free survival (AFS), wound healing, and health-related quality of life (HRQoL). METHODS Our study included 131 elderly CLTI patients aged ≥70 years who underwent infrainguinal endovascular interventions between April 2018 and August 2021, with a follow-up period of 2 years. Among the patients, 93.9% had diabetes mellitus and 82.4% had hypertension. Clinical frailty was assessed using the clinical frailty scale (CFS). Patients were categorized into group 1 (CFS 1-5) and group 2 (CFS 6-9). Primary outcomes were AFS, wound healing, HRQoL, and their association with frailty. Secondary outcomes included technical success, procedure-related complications, major adverse limb events, major adverse cardiac events, vessel patency, re-intervention rates, and mortality rates including periprocedural and overall mortality. RESULTS Technical success was achieved in 86.3% of patients, with frailty significantly influencing this outcome. Group 2 exhibited reduced technical success (80.8%) compared to group 1 (93.1%). The major amputation rate was 9.2%, with higher rates in group 2 [univariate hazard ratio: 5.20; P = 0.033]. Similarly, group 2 showed elevated overall mortality [univariate hazard ratio: 5.18; P < 0.001]. AFS at 1 and 2 years were 67.9% and 55%, respectively, with higher rates in group 1. Wound healing was achieved in 76.1% of patients (83/109), with frailty significantly associated with delayed wound healing (P < 0.001). Vessel patency at 1 year was observed in 88.8% of patients. HRQoL significantly improved postintervention, with vascular quality of life questionnaire-6 (VascuQol-6) scores increasing from an average of 9 of 24 at baseline to 20 of 24 at 2 years. Frailty score significantly correlated with VascuQol-6 scores at 1 and 2 years (P < 0.0012). Group 1 exhibited higher VascuQol-6 scores than group 2, indicating improved HRQoL during follow-up. CONCLUSIONS Successful endovascular treatments in high-risk CLTI patients promote improved wound healing and post-treatment quality of life. Frailty should be assessed before endovascular interventions as it correlates with adverse outcomes, including amputations and mortality. While revascularization holds promise, caution is advised for frailer patients, emphasizing the importance of personalized care and tailored treatments for elderly CLTI patients.

Abstract
Occlusive lesions of the common femoral artery (CFA) and its bifurcation have traditionally been treated with open surgery. Although long-term patency rates after open surgery are excellent, such repairs are associated with substantial local and general morbidity. In recent years, different treatment options have emerged within percutaneous endovascular repair. We hereby present a narrative review on endovascular treatment modalities and a treatment algorithm for endovascular revascularisation of the CFA and its bifurcation. Lesion analysis, access issues, vessel preparation tools, and types of repairs with or without the involvement of the bifurcation are described. Based on current data, an interventional approach can result in high technical success and acceptable mid-term patency rates. Further comparative evidence with open surgery and/or between the different types of endovascular repairs is required to improve the current treatment algorithm.

Abstract
Background/Objectives: Retrograde access of the peroneal artery (PA) is considered technically challenging and at risk of bleeding. The aim of this multicentre retrospective study was to assess the safety, feasibility, and technical success of this access route for infrainguinal endovascular recanalizations. Methods: We retrospectively analyzed 186 consecutive patients treated over a 7-year period (May 2014-August 2021) who underwent endovascular recanalization of infra-inguinal lesions using a PA access route. In all cases, retrograde PA access was obtained following a failed attempt to cross the occlusion via the antegrade route. Results: Among the 186 patients, 120 were males (60.5%) and the mean age was 76.8 ± 10.7 years old (44-94 years). One hundred and thirteen patients (60.7%) suffered from chronic limb threatening ischemia (CLTI). All patients presented with chronic total occlusions (CTO) and a failed conventional antegrade recanalization attempt. Retrograde access was performed under angiographic guidance in 185 cases (99.5%). It was successfully established in 171 cases (91.9%). The total rate of retrograde puncture-related complications was 2.1% (two puncture site bleedings of which one necessitated fasciotomy and two cases of arteriovenous fistulas managed conservatively). The Major Adverse Event (MAE) rate at 30 days was 1.6% (3/186). Conclusions: Retrograde recanalization of challenging infra-inguinal lesions via PA is safe and effective in experienced hands.

J Vasc Surg 2024:S0741-5214(24)01093-0. [PMID: 38718850 DOI: 10.1016/j.jvs.2024.04.067] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 04/26/2024] [Accepted: 04/29/2024] [Indexed: 05/12/2024]
Abstract
OBJECTIVE The recent Best Endovascular vs Best Surgical Therapy in Patients with Critical Limb Ischemia (BEST-CLI) study showed that bypass was superior to endovascular therapy (ET) in patients with chronic limb-threatening ischemia (CLTI) deemed suitable for either approach who had an available single-segment great saphenous vein (GSV). However, the superiority of bypass among those lacking GSV was not established. We aimed to examine comparative treatment outcomes from a real-world CLTI population using the Vascular Quality Initiative-Medicare-linked database. METHODS We queried the Vascular Quality Initiative-Medicare-linked database for patients with CLTI who underwent first-time lower extremity revascularization (2010-2019). We performed two one-to-one propensity score matchings (PSMs): ET vs bypass with GSV (BWGSV) and ET vs bypass with a prosthetic graft (BWPG). The primary outcome was amputation-free survival. Secondary outcomes were freedom from amputation and overall survival (OS). RESULTS Three cohorts were queried: BWGSV (N = 5279, 14.7%), BWPG (N = 2778, 7.7%), and ET (N = 27,977, 77.6%). PSM produced two sets of well-matched cohorts: 4705 pairs of ET vs BWGSV and 2583 pairs of ET vs BWPG. In the matched cohorts of ET vs BWGSV, ET was associated with greater hazards of death (hazard ratio [HR] = 1.34, 95% confidence interval [CI], 1.25-1.43; P < .001), amputation (HR = 1.30, 95% CI, 1.17-1.44; P < .001), and amputation/death (HR = 1.32, 95% CI, 1.24-1.40; P < .001) up to 4 years. In the matched cohorts of ET vs BWPG, ET was associated with greater hazards of death up to 2 years (HR = 1.11, 95% CI, 1.00-1.22; P = .042) but not amputation or amputation/death. CONCLUSIONS In this real-world multi-institutional Medicare-linked PSM analysis, we found that BWGSV is superior to ET in terms of OS, freedom from amputation, and amputation-free survival up to 4 years. Moreover, BWPG was superior to ET in terms of OS up to 2 years. Our study confirms the superiority of BWGSV to ET as observed in the BEST-CLI trial.

Abstract
OBJECTIVE Inframalleolar disease is present in most diabetic patients presenting with tissue loss. Inframalleolar (pedal) artery disease and pedal medial arterial calcification (pMAC) are associated with major amputation in patients with chronic limb-threatening ischemia (CLTI). This study aimed to examine the impact of pMAC on the outcomes after isolated inframalleolar (pedal artery) interventions. METHODS A database of lower extremity endovascular intervention for patients with tissue loss between 2007 and 2022 was retrospectively queried. Patients with CLTI were selected, and those undergoing isolated inframalleolar intervention on the dorsalis pedis and medial and lateral tarsal arteries and who had foot x-rays were identified. X-rays were assessed blindly for pMAC and scored on a scale of 0 to 5. Patients with concomitant superficial femoral artery and tibial interventions were excluded. Intention to treat analysis by the patient was performed. Amputation-free survival (survival without major amputation) was evaluated. RESULTS A total of 223 patients (51% female; 87% Hispanic; average age, 66 years; 323 vessels) underwent isolated infra-malleolar intervention for tissue loss. All patients had diabetes, 96% had hypertension, 79% had hyperlipidemia, and 63% had chronic renal insufficiency (55% of these were on hemodialysis). Most of the patients had Wound, Ischemia, and foot Infection (WIfI) stage 3 disease and had various stages of pMAC: severe (score = 5) in 48%, moderate (score = 2-4) in 31%, and mild (score = 0-1) in 21% of the patients. Technical success was 94%, with a median of one vessel treated per patient. All failures were in severe pMAC. Overall, major adverse cardiovascular events was 0.9% at 90 days after the procedure. Following the intervention, most patients underwent a planned forefoot amputation (single digit, multiple digits, ray amputation, or trans-metatarsal amputation). WIfI ischemic grade was improved by 51%. Wound healing at 3 months was 69%. Those not healing underwent below-knee amputations. The overall 5-year amputation-free survival rate was 35% ± 9%. The severity of pMAC was associated with decreased AFS. CONCLUSIONS Increasing severity of pMAC influences the technical and long-term outcomes of infra-malleolar intervention in diabetes. Severe pMAC is associated with amputation and should be considered as a variable in the shared decision-making of diabetic patients with CLTI.

Abstract
INTRODUCTION Partial calcanectomy (PC) can be performed to treat chronic heel ulcers in patients with calcaneal osteomyelitis. Patients undergoing PC often have multiple comorbidities, limited mobility, and face high risk of major limb amputation. This study examined the extent of vascular diagnostic testing and interventions as well as long-term outcomes in patients undergoing PC. METHODS A retrospective analysis was performed on patients who underwent PC for non-healing calcaneal ulcer over a ten-year period. Demographics, comorbidities, vascular testing, and procedural data were recorded. Additional subgroup analysis was performed according to presence or absence of peripheral arterial disease (PAD). Primary outcomes were major limb amputation (above or below the knee) and mortality. Secondary outcomes included successful wound healing, time to complete wound healing, re-interventions, and change in ambulatory status. RESULTS A total of 157 patients underwent partial calcanectomies on 162 limbs. 78.3% of patients had diabetes mellitus and 47.8% were diagnosed with PAD. Ankle brachial index with pulse volume recording (ABI/PVR) was performed for 46.5% (73/157) of patients, arterial duplex in 44.6% (70/157), and 19.7% (31/157) had a computed tomography angiogram. Lower extremity revascularization was performed in 28.4% of limbs (46/162). Independent ambulatory status was reported in 40.1% prior to PC and decreased to 17.9% by the time of last recorded follow-up (p < .00001). Long-term amputation-free survival was significantly higher in patients without PAD at 7 years (78.4% vs 57.1%, p = .02). Multivariate logistic regression analysis demonstrated that PAD and end-stage renal disease (ESRD) increased the odds of major limb amputation (OR 3.5 and 2.8, respectively), whereas ESRD and adjuvant podiatric procedures were associated with increased mortality (OR 4.8 and 4.8, respectively). CONCLUSION Non-invasive vascular testing should be obtained in all patients undergoing PC, in order to stratify risk of amputation and identify candidates for revascularization. Over the long-term, patients undergoing PC face significant risk of prolonged wound healing, decline in ambulatory status, and major limb amputation.

Abstract
CLINICAL IMPACT This retrospective observational registry trial combines national registries for vascular surgical procedures and diabetes mellitus to clarify results of drug eluting technology in treating diabetic subjects with intermittent claudication or chronic limb threatening ischemia compared to treatment of non-diabetic subjects. As earlier proposed and showed in this trial, there may be an implication for a beneficial treatment efficacy with drug eluting therapy in the diabetic population with PAD compared to the non-diabetic population. A finding worth further exploration.

Abstract
Advanced endovascular techniques are increasingly being utilized to treat patients with peripheral arterial disease and chronic limb-threatening ischemia to improve lower extremity arterial perfusion. In diabetic patients, pedal arch patency has been associated with improved wound healing, limb salvage, and overall survival. Pedal-plantar loop revascularization is a technique that can restore arterial inflow between the dorsal and plantar arteries of the foot. This article will describe the inframallelolar arterial anatomy and focus on imaging, percutaneous endovascular techniques, and clinical study outcomes of pedal artery interventions.

Abstract
Background Iliac artery stenosis or occlusion is a critical condition that can severely impact a patient's quality of life. The effectiveness of balloon angioplasty and intraluminal stenting for the treatment of iliac artery lesions classified as TASC II A and B was evaluated in this single-center prospective study. Methods Conducted between October 2016 and September 2020 at Cho Ray Hospital's Vascular Surgery Department, this prospective study involved PAD patients categorized by TASC II A and B classifications who underwent endovascular intervention. Intervention outcomes were assessed peri-procedure and during short-term and mid-term follow-ups. Results Of the total of 133 patients, 34.6% underwent balloon angioplasty, while 65.4% received stenting. The immediate technical success rate was 97.7%, while the clinical success rate was 62.4%. Complications were minimal, with major limb amputation reported in 1.5% of the cases. There was a significant improvement in Rutherford classification and ABI at short-term follow-up, with a patency rate of 90.2%. The mid-term post-intervention follow-up yielded similar results with an 86.1% patency rate. The mortality rates associated with arterial occlusion were 2.3% during short-term follow-up and 1.7% during mid-term follow-up. Conclusion Balloon angioplasty and stent placement are effective and safe interventions for TASC II A and B iliac artery occlusions with favorable short and mid-term outcomes. Further, multi-center studies with larger sample sizes are recommended for more comprehensive conclusions, including long-term follow-up assessment.

Combination of BeGraft and Solaris Stent Grafts for the Covered Endovascular Reconstruction of Aortic Bifurcation-BS-CERAB Technique. J Clin Med 2024; 13:1925. [PMID: 38610690 PMCID: PMC11012459 DOI: 10.3390/jcm13071925] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2024] [Revised: 03/14/2024] [Accepted: 03/21/2024] [Indexed: 04/14/2024] Open
Abstract
Background: This study examines the impact of the use of the combination of BeGraft and Solaris stent grafts on the outcomes during the covered endovascular reconstruction of aortic bifurcation (BS-CERAB) technique and extension to the iliac arteries. Methods: Consecutive patients with aortoiliac occlusive disease who underwent endovascular treatment using BS-CERAB between January 2020 and December 2023 were included. Patient demographics, symptoms, lesion characteristics, and procedural and follow-up details were collected and analyzed. Perioperative complications and reinterventions were also identified. Results: A total of 42 patients met the inclusion criteria (32 men, 76.2%, median age 72 years, range 59-85). Indications for treatment were intermittent claudication (42.9%) and critical limb ischemia (57.1%). Procedure success was achieved in all cases. The median patient follow-up time was 14 months (1-36). One patient died at a 10-month follow-up due to lung cancer. The mean pre-operative ABI increased from 0.37 ± 0.19 before intervention to 0.71 ± 1.23 post-operatively at 12 months (p = 0.037). The estimated primary patency rates at 3, 6, and 12 months were 90.5%, 85.7%, and 81.0% and primary assisted patency rates were 90.5%, 90.5%, and 85.7%, respectively. Secondary patency was 95.2% at 3 and 6 months and 90.5% at a 12-month follow-up. Active cancer (p = 0.023, OR 2.12 95%CI 1.14-3.25) was a risk factor for restenosis. Conclusions: This mid-term experience shows that the CERAB technique using the combination of BeGraft and Solaris stents grafts, for the endovascular treatment of severe aortoiliac atherosclerotic disease, may allow an effective reconstruction of the aortic bifurcation and iliac arteries related to high-patency and lower-reintervention rates.

Revascularization Outcomes Stratified by Glycemic Control in Patients with Diabetes Mellitus and Chronic Limb-Threatening Ischemia. Ann Vasc Surg 2024; 100:91-100. [PMID: 38122976 PMCID: PMC10922710 DOI: 10.1016/j.avsg.2023.10.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Revised: 10/12/2023] [Accepted: 10/19/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND The prevalence of chronic limb-threatening ischemia (CLTI) has increased alongside rising rates of diabetes mellitus (DM). While diabetic patients with CLTI have worse outcomes compared to patients without diabetes, conflicting data exist on the relationship between the severity of DM and CLTI outcomes. Close inspection of the relationship between DM severity and outcomes in CLTI may benefit surgical decision-making and patient education. METHODS We retrospectively reviewed patients who received endovascular intervention or surgical bypass for CLTI at our multidisciplinary Limb Preservation Program from 2013 to 2019 to collect patient characteristics using Society for Vascular Surgery (SVS) reporting standards, arterial lesion characteristics from recorded angiograms, and outcomes, including survival, amputation, wound healing, and revascularization patency. Controlled DM was defined as SVS Grade 1 (controlled, not requiring insulin) and Grade 2 (controlled, requiring insulin), while uncontrolled DM was defined as SVS Grade 3 (uncontrolled), and DM severity was assessed using preoperative hemoglobin A1c (HgbA1c) values. Product-limit Kaplan-Meier was used to estimate survival functions. Univariable Cox proportional hazards analyses guided variable selection for multivariable analyses. RESULTS Our Limb Preservation Program treated 177 limbs from 141 patients with DM. Patients with uncontrolled DM were younger (60.44 ± 10.67 vs. 65.93 ± 10.89 years old, P = 0.0009) and had higher HgbA1c values (8.97 ± 1.85% vs. 6.79 ± 1.10%, P < 0.0001). Fewer patients with uncontrolled DM were on dialysis compared to patients with controlled DM (15.6% vs. 30.9%, P = 0.0278). By Kaplan-Meier analysis, DM control did not affect time to mortality, limb salvage, wound healing, or loss of patency. However, multivariable proportional hazards analysis demonstrated increased risk of limb loss in patients with increasing HgbA1C (hazard ratio (HR) = 1.96 [1.42-2.80], P < 0.0001) or dialysis dependence (HR = 15.37 [3.44-68.73], P = 0.0003), increased risk of death in patients with worsening pulmonary status (HR = 1.70 [1.20-2.39], P = 0.0026), and increased risk of delayed wound healing in patients who are male (HR = 0.48 [0.29-0.79], P = 0.0495). No independent association existed between loss of patency with any of the variables we collected. CONCLUSIONS Patients with uncontrolled DM, as defined by SVS reporting standards, do not have worse outcomes following revascularization for CLTI compared to patients with controlled DM. However, increasing HgbA1c is associated with a greater risk for early amputation. Before revascularization, specific attention to the level of glycemic control in patients with DM is important, even if DM is "controlled." In addition to aggressive attempts at improved glycemic control, those with elevated HgbA1c should receive careful education regarding their increased risk of amputation despite revascularization. Future work is necessary to incorporate the severity of DM into risk models of revascularization for the CLTI population.

Abstract
INTRODUCTION This article aims to evaluate the short-term and mid-term performance of a self-expanding covered stent (COVERA Plus, Bard Tempe, Arizona) during the treatment of Trans-Atlantic Inter-Society Consensus (TASC) C/D aortoiliac obstructive lesions involving the aortic bifurcation. METHODS A single-center retrospective review of all patients who underwent endovascular reconstruction of the aortoiliac bifurcation for obstructive disease, with the use of Covera, from January 2018 to March 2023. All patients received a postoperative CTA (computed tomography angiography) scan within 1 month from the intervention. Precision of deployment, stent conformation, and stent symmetry were evaluated at the arterial phase of the CTA. Early outcomes were technical success and freedom from open aortic reintervention and/or mortality. Late outcomes were primary and assisted primary patency rates and freedom from reintervention. RESULTS During the study period, 35 patients underwent primary endovascular treatment of obstructive lesions involving the aortic bifurcation with parallel COVERA stents. Aortoiliac lesions were classified as TASC-IIC in 23 (65.7%) patients and TASC D in 12 (34.2%). Median follow-up was 49 months (interquartile [IQR]: 18-60). Overall survival was 97.1% (95% confidence interval [CI]=91-100) at 60 months. During follow-up, there were one early stent stenosis, treated with an angioplasty and stent relining with an estimated primary patency at 60 months of 97.1% (95% CI=94-100) and a primary-assisted patency of 100%. Estimated freedom from all types of reinterventions at 60 months was 94.3% (95% CI=89-99.3). CONCLUSIONS The new self-expanding covered Bard COVERA Plus stent used for endovascular treatment of TASC C/D aorto iliac disease proved to be safe and feasible with high technical procedural success rates. Comparison with other types of stents is necessary to further assess the role of the COVERA Plus stent in aortic bifurcation repair. CLINICAL IMPACT This study investigates the safety and feasibility of the new self-expanding covered Bard Covera Plus stent used for endovascular treatment of TASC C/D aorto iliac disease. The retrospective analysis of 35 patients highlights high technical success and primary patency rate at 60 months. The geometric analysis also helped to underline how this stent can be used precisely in particular conditions. These findings suggest the need for further research to compare COVERA with other types of stents in aortic bifurcation repair.

Abstract
BACKGROUND Peripheral arterial disease (PAD) is the obstruction or narrowing of the large arteries of the lower limbs, which can result in impaired oxygen supply to the muscle and other tissues during exercise, or even at rest in more severe cases. PAD is classified into five categories (Fontaine classification). It may be asymptomatic or various levels of claudication pain may be present; at a later stage, there may be ulceration or gangrene of the limb, with amputation occasionally being required. About 20% of people with PAD suffer from intermittent claudication (IC), which is muscular discomfort in the lower extremities induced by exertion and relieved by rest within 10 minutes; IC causes restriction of movement in daily life. Treatment for people with IC involves addressing lifestyle risk factors. Exercise is an important part of treatment, but supervised exercise programmes for individuals with IC have low engagement levels and high attrition rates. The use of mobile technologies has been suggested as a new way to engage people with IC in walking exercise interventions. The novelty of the intervention, low cost for the user, automation, and ease of access are some of the advantages mobile health (mhealth) technologies provide that give them the potential to be effective in boosting physical activity in adults. OBJECTIVES To assess the benefits and harms of mobile health (mhealth) technologies to improve walking distance in people with intermittent claudication. SEARCH METHODS The Cochrane Vascular Information Specialist conducted systematic searches of the Cochrane Vascular Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and CINAHL, and also searched the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) and ClinicalTrials.gov. The most recent searches were carried out on 19 December 2022. SELECTION CRITERIA We included randomised controlled trials (RCTs) in people aged 18 years or over with symptomatic PAD and a clinical diagnosis of IC. We included RCTs comparing mhealth interventions to improve walking distance versus usual care (no intervention or non-exercise advice), exercise advice, or supervised exercise programmes. We excluded people with chronic limb-threatening ischaemia (Fontaine III and IV). DATA COLLECTION AND ANALYSIS We used standard Cochrane methods. Our primary outcomes were change in absolute walking distance from baseline, change in claudication distance from baseline, amputation-free survival, revascularisation-free survival. Our secondary outcomes were major adverse cardiovascular events, major adverse limb events, above-ankle amputation, quality of life, and adverse events. We used GRADE to assess the certainty of the evidence. MAIN RESULTS We included four RCTs involving a total of 614 participants with a clinical diagnosis of IC. The duration of intervention of the four included RCTs ranged from 3 to 12 months. Participants were randomised to either mhealth or control (usual care or supervised exercise programme). All four studies had an unclear or high risk of bias in one or several domains. The most prevalent risk of bias was in the area of performance bias, which was rated high risk as it is not possible to blind participants and personnel in this type of trial. Based on GRADE criteria, we downgraded the certainty of the evidence to low, due to concerns about risk of bias, imprecision, and clinical inconsistency. Comparing mhealth with usual care, there was no clear evidence of an effect on absolute walking distance (mean difference 9.99 metres, 95% confidence interval (CI) -27.96 to 47.93; 2 studies, 503 participants; low-certainty evidence). None of the included studies reported on change in claudication walking distance, amputation-free survival, or revascularisation-free survival. Only one study reported on major adverse cardiovascular events (MACE) and found no clear difference between groups (risk ratio 1.37, 95% CI 0.07 to 28.17; 1 study, 305 participants; low-certainty evidence). None of the included studies reported on major adverse limb events (MALE) or above-ankle amputations. AUTHORS' CONCLUSIONS Mobile health technologies can be used to provide lifestyle interventions for people with chronic conditions, such as IC. We identified a limited number of studies that met our inclusion criteria. We found no clear difference between mhealth and usual care in improving absolute walking distance in people with IC; however, we judged the evidence to be low certainty. Larger, well-designed RCTs are needed to provide adequate statistical power to reliably evaluate the effects of mhealth technologies on walking distance in people with IC.

Abstract
Background Patients with chronic limb threatening ischemia (CLTI) of the lower limbs (LL) undergo arteriography for revascularization surgery planning. Doppler ultrasound (DU) is non-invasive and can provide information about the distal arteries through measurement of the resistance index (RI). Objectives To correlate the Rutherford Angiographic Classification with the RI for assessment of the distal arterial bed of the LL. Methods A cross-sectional study, conducted at a public tertiary hospital with 120 patients with LL CLTI, from September 2019 to April 2022. The RI of arteries that were candidates for revascularization was compared with the images of the same arteries obtained using arteriography, using the Rutherford Angiographic Classification of the distal bed. Results A total of 120 LL were assessed in 120 patients with a mean age of 68.6 years. The sample was 50.0% male and 90.0% of the patients in the sample were classified as Rutherford category five. The RI values found for the arteries of the leg exhibited a statistically significant positive correlation with the Rutherford Classification (anterior tibial, p< 0.01; posterior tibial, p = 0.012 fibular, p = 0.034; and dorsalis pedis, p < 0.001). Conclusions In this study, RIs for the arteries of the leg measured using Doppler ultrasound exhibited a positive correlation with the Rutherford Classification. This index could be useful for assessment of the distal arterial bed of the lower limbs of patients with chronic limb threatening ischemia.

Abstract
OBJECTIVE We retrospectively compared the clinical outcomes of self-expanding covered stents (CSs) and bare metal stents (BMSs) in the treatment of aortoiliac occlusive disease (AIOD) at a single center between 2016 and 2022. METHODS All patients with AIOD receiving endovascular therapy at a single center from January 2016 to October 2022 were continuously analyzed, including patients with lesions of all classes according to the Trans-Atlantic Inter-Society Consensus II (TASC-II). Relevant clinical and baseline data were collected, and propensity score matching was performed to compare CSs and BMSs in terms of baseline characteristics, surgical factors, 30-day outcomes, 5-year primary patency, and limb salvage. The follow-up results were analyzed by Kaplan-Meier curves. Cox proportional hazard models were used to identify predictors of primary patency. RESULTS A total of 209 patients with AIOD were enrolled in the study, including 135 patients (64.6%) in the CS group and 74 patients (35.4%) in the BMS group. Surgical success rates (100% vs 100%; P = 1.00), early (<30-day) mortality rates (0% vs 0%; P = 1.00), cumulative surgical complication rate (12.0% vs 8.0%; P = .891), 5-year primary patency rate (83.4% vs 86.9%; P = .330), secondary patency rate (96% vs 100%; P = .570), and limb salvage rate (100% vs 100%; P = 1.00) did not exhibit significant differences between the two groups. Patients in the CS group had a lower preoperative ankle-brachial index (0.48 ± 0.26 vs 0.52 ± 0.19; P = .032), more cases of complex AIOD (especially TASC D) (47.4% vs 9.5%; P < .001), more chronic total occlusive lesions (77.0% vs 31.1%; P < .001), and more severe calcification (20.7% vs 14.9%; P < .036). After propensity score matching, 50 patients (25 with CS and 25 with BMS) were selected. The results showed that only severe calcification (32.0% vs 8.0%; P = .034) and ankle-brachial index increase (0.45 ± 0.15 vs 0.41 ± 0.22; P = .038) were significantly different between the groups. In terms of surgical factors, patients in the CS group had more use of bilateral femoral or combined brachial artery percutaneous access (60.0% vs 12.0%; P < .001), more number of stents used (2.3 ± 1.2 vs 1.3 ± 0.7; P < .001), longer mean stent length (9.3 ± 3.3 vs 5.8 ± 2.6 cm; P < .001), and more catheter-directed thrombolysis treatment (32.0% vs 4.0%; P = .009). Multivariate Cox survival analysis showed that severe calcification (hazard ratio, 1.32; 95% confidence interval, 1.04-1.85; P = .048) was the only independent predictor of the primary patency rate. CONCLUSIONS All patients with AIOD who underwent endovascular therapy were included and achieved good outcomes with both CSs and BMSs. The influence of confounding factors in the two groups was minimized by propensity score matching, and the 5-year patency rates were generally similar in the unmatched and matched cohorts. Postoperative hemodynamic improvement was more obvious in patients in the CS group. For more complex lesions, CS is recommended to be preferred. Especially for severe calcification lesions, which is the only independent predictor of primary patency, CS showed obvious advantages. Further studies with more samples are needed to investigate the role of stent types in AIOD treatment.

Abstract
OBJECTIVE Superficial femoral artery (SFA) stenting is a common treatment for peripheral artery disease. It is effective in the short term; however, in-stent restenosis (ISR) limits long-term success. Surveillance with duplex ultrasound (DUS) can identify patients who develop ISR leading to early reintervention, but data to support this practice is sparce. The purpose of this study was to evaluate whether surveillance and subsequent reintervention improves outcomes in patients with SFA stents. METHODS A single-center, retrospective study was performed with patients undergoing SFA stenting between 2005 and 2020 who had a follow-up with DUS. Five groups were identified based on the presence of ISR on DUS (ISR vs no ISR [NISR]), recurrence of symptoms (symptomatic [SX] vs asymptomatic [ASX]), and if any reintervention was performed (reintervention [R] vs no reintervention [NR]): (1) ISR+SX+R; (2) ISR+SX+NR; (3) ISR+ASX+R; (4) ISR+ASX+NR; and (5) NISR+NR. The primary endpoint was amputation-free survival, and the secondary endpoint was patency. Predictors of mortality and surveillance were identified by multivariable logistic regressions and Cox multivariate regression models. Survival curves were presented as Kaplan-Meier plots using log-rank test for subgroup comparison. RESULTS Two hundred fifty-seven patients were included in the analysis. The indication for intervention was claudication in 28% and chronic limb-threatening ischemia in 72%. A total of 161 patients (63%) underwent reintervention for ISR. Of patients who had restenosis on DUS, those who were symptomatic and did not undergo reintervention (ISR+SX+NR) did the worst, with 50% amputation rate. In contrast, those who were asymptomatic but did undergo reintervention (ISR+ASX+R) had the lowest amputation rate of 13%. Active smoking was a predictor of both loss of patency and amputation (1.72; 95% confidence interval [CI], 1.00-2.98; P = .050; 3.55; 95% CI, 1.53-8.25; P = .003). Post procedure dual antiplatelet therapy had a positive association with limb salvage (hazard ratio [HR], 0.23; 95% CI, 0.09-0.58; P = .001), whereas diabetes (HR, 2.61; 95% CI, 1.21-6.01; P = .019), stent occlusion (HR, 17.0; 95% CI, 5.93-63.1; P < .001), and chronic limb-threatening ischemia presentations (HR, 4.31; 95% CI, 1.86-11.7; P=.002) were negatively associated with limb salvage. CONCLUSIONS Routine surveillance DUS and subsequent reintervention on ISR after SFA stenting is associated with improved patency and amputation-free survival. Surveillance DUS should be routine for patients after stenting, with reintervention strongly considered if ISR is identified for both symptomatic and asymptomatic.

Direct puncture versus contralateral femoral artery approach for catheter-directed thrombolysis of occluded infra-inguinal arterial bypass grafts. Clin Radiol 2023; 78:e1001-e1009. [PMID: 37806817 DOI: 10.1016/j.crad.2023.08.028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2023] [Revised: 08/28/2023] [Accepted: 08/31/2023] [Indexed: 10/10/2023]
Abstract
AIM To compare the safety, effectiveness, and clinical outcome of percutaneous direct puncture approach versus contralateral femoral native vessel approach for catheter-directed thrombolysis of occluded infra-inguinal bypass grafts. MATERIALS AND METHODS A retrospective analysis was performed comprising a cohort of patients who underwent catheter-directed thrombolysis procedures of occluded infra-inguinal bypass grafts between January 2013 and January 2022, with a follow-up period until June 2022. This included 55 procedures via the native vessel approach and 18 procedures via the direct puncture approach. Primary outcomes were technical success and procedural safety; secondary outcomes included re-intervention rate, limb salvage, and mortality as assessed by log-rank testing and Kaplan-Meier curves. RESULTS There were no differences between the two groups with regard to patient demographics, except for the number of previous vascular procedures (n=6.83 ± 3.07 direct approach versus n=4.96 ± 2.79 native vessel approach, p=0.025). Thrombolysis was comparably successful in both groups (n=13/18; 72% direct approach versus n=42/55; 76%, p=0.723). There were no differences in the duration of thrombolysis administration. The rate of adverse events was slightly lower in the direct approach group, but without significance (p=0.092). There were no adverse events related to the puncture site in the direct approach group. No differences were found between the time-to-event values for re-occlusion, re-intervention, amputation, or mortality respectively (p=0.662; p=0.520; p=0.816; p=0.462). CONCLUSION The direct puncture approach seems to be a safe and efficient approach for catheter-directed thrombolysis procedures in infra-inguinal occluded bypass grafts, with clinical outcomes comparable to the native vessel approach.

Abstract
With the growing prevalence and mortality of peripheral arterial disease, preoperative assessment, risk stratification, and determining the correct indication for endovascular and open surgical procedures are essential for therapeutic decision-making. The effectiveness of interventional procedures is significantly influenced by the plaque composition and calcification pattern. Therefore, the identification of patients for whom endovascular treatment is the most appropriate therapeutic solution often remains a challenge. The most commonly used imaging techniques have their own limitations and do not provide findings detailed enough for specific, personalized treatment planning. Using state-of-the-art noninvasive and invasive imaging modalities, it is now possible to obtain a view, not only of the complex vascular anatomy and plaque burden of the lower extremity arterial system, but also of complex plaque structures and various pathologic calcium distribution patterns. In the future, as these latest advancements in diagnostic methods become more widespread, we will be able to obtain more accurate views of the plaque structure and anatomic complexity to guide optimal treatment planning and device selection. We reviewed the implications of the most recent invasive and noninvasive lower extremity imaging techniques and future directions.

Abstract
BACKGROUND Evidence regarding the outcomes of Omniflow® II prosthesis in peripheral arterial revascularization at different anatomical sites and for different indications is scarce. Therefore, the aim of this study was to evaluate the outcomes of the Omniflow® II used at various positions within the femoral tract both in infected and non-infected setting. METHODS Patients who underwent reconstructive lower leg vascular surgery with implantation of an Omniflow® II from 2014 until 2021 at five medical centers were retrospectively included (N.=142). Patients were subdivided into the following categories: femoro-femoral crossover (N.=19), femoral interposition (N.=18), femoro-popliteal (above-the-knee [N.=25; AK] or below-the-knee [N.=47; BK]), and femoro-crural bypass grafts (N.=33). Primary outcome was primary patency and secondary outcomes included primary assisted patency, secondary patency, major amputation, vascular graft infection, and mortality. Outcomes were compared according to different subgroups and the surgical setting (infected versus non-infected). RESULTS The median follow-up was 35.0 (17.5-54.3) months. Three years primary patency of 58% was observed for femoro-femoral crossover bypass, 75% for femoral interposition graft, 44% for femoro-popliteal above-the-knee bypass, 42% for femoro-popliteal below-the-knee bypass, and 27% in the femoro-crural position (P=0.006). Freedom from major amputation at three years were 84% for femoro-femoral crossover bypass, 88% for femoral interposition bypass, 90% for femoro-popliteal AK bypass, 83% for femoro-popliteal BK bypass, and 50% for femoro-crural bypass (P<0.001). CONCLUSIONS This study demonstrates the safety and feasibility of the use of Omniflow® II for femoro-femoral crossover-, femoral interposition-, and femoro-popliteal (AK and BK) bypass. Omniflow® II seems to be less suitable for femoro-crural bypass with a significantly lower patency compared to other positions.

Abstract
PURPOSE Unfractionated heparin is widely used to lower the risk of arterial thromboembolic complications (ATECs) during interventions for peripheral arterial disease (PAD), but it is still unknown which heparin dose is the safest in terms of preventing ATECs and bleeding complications. This study aims to evaluate the incidence of complications during interventions for PAD and the relation between this incidence and different heparinization protocols. MATERIALS AND METHODS A retrospective analysis of a prospective multicenter cohort study was performed. Between June 2015 and September 2022, 355 patients who underwent peripheral interventions for PAD were included. All patients who were included before July 2018 received 5000 international units (IU) of heparin (group 1). Starting from July 2018, all included patients received an initial dose of 100 IU/kg, with potential additional heparin doses based on activated clotting time (ACT) values (group 2). Data on ACT values and complications within 30 days post-procedurally were collected. RESULTS In total, 24 ATECs and 48 bleeding complications occurred. In group 1, 8.7% (n=11) of patients suffered from ATEC, compared with 5.7% (n=13) in group 2. Thirteen percent of patients (n=17) in group 1 had a bleeding complication, compared with 14% (n=31) in group 2. Arterial thromboembolic complications were more often found in patients with peak ACT values of <200 seconds, compared with ACT values between 200 and 250 seconds, 15% (n=6) versus 5.9% (n=9), respectively, p=0.048. Patients with peak ACT values >250 seconds had a higher incidence of bleeding complications compared with an ACT between 200 and 250 seconds, 24% (n=21) versus 9.8% (n=15), respectively, p=0.003. Forty-four percent of patients (n=23) in group 1 reached a peak ACT of >200 seconds, compared with 95% (n=218) of patients in group 2 (p=0.001). CONCLUSION ATEC was found in 6.8% (n=24) and bleeding complications in 14% (n=48) of patients who underwent a procedure for PAD. There was a significantly higher incidence of ATECs in patients with a peak ACT value <200 seconds, and a higher incidence of bleeding complications in patients with a peak ACT value >250 seconds. The findings obtained from this study may serve as a basis for conducting future research on heparinization during procedures for PAD, with a larger sample size. CLINICAL IMPACT Heparin is administered during arterial interventions for peripheral arterial disease (PAD) to decrease the risk of arterial (thrombo)embolic complications (ATEC) during or shortly following surgery. The effect of heparin is unpredictable in the individual patient, and the optimal dosage of this anticoagulant has not yet been established. Using the activated clotting time (ACT), the anticoagulatory effect of heparin can be monitored periprocedurally. Previous research on the incidence of both ATEC and bleeding complications, or on the optimal dosage of heparin administration, is scarce. This study aims to investigate the incidence of ATEC and bleeding complications between 2 different dosage protocols of heparin-a standard bolus of 5000 IU or ACT-guided heparinization-and thereby provide clarity on the optimal dose of heparin during peripheral arterial interventions for PAD.

Abstract
PURPOSE This study aimed to compare midterm efficacy between drug-coated balloon (DCB) and bare metal stent (BMS) in the treatment of TASCII C/D femoropopliteal artery lesions. METHODS The clinical data of patients with TASCII C/D femoropopliteal artery disease admitted to 3 vascular surgery centers from January 2018 to January 2021 were retrospectively analyzed. Patients were divided into DCB group and BMS group. The DCB group was further subdivided into DCB alone subgroup and DCB+BMS subgroup. Study primary outcomes were freedom from clinical-driven target lesion reintervention (FCD-TLR) at 24 months postprocedure. Secondary outcomes included ankle brachial index (ABI), Rutherford classification, major amputation rate, and mortality. RESULTS A total of 410 consecutive patients were enrolled. At 24 months follow-up, in DCB group (114 patients) relative to BMS group (296 patients), FCD-TLR (86.00% vs 71.91%, p=0.039), and ABI (0.53±0.11 vs 0.47±0.19, p=0.007) were higher; mean Rutherford class was lower (1.57±0.68 vs 3.31±1.39, p=0.000); and major amputation rate (0.87% vs 4.05%, p>0.05) and all-cause mortality (8.92% vs 6.41%, p>0.05) were statistically similar. In DCB alone, subgroup relative to DCB+BMS subgroup, FCD-TLR (90.00% vs 85.00%, p>0.05), major amputation rate (0 vs 1.08%, p>0.05), and all-cause mortality rate (9.09% vs 8.69%, p>0.05) were statistically similar, while FCD-TLR was higher in the DCB+BMS subgroup (90.00% vs 71.91%, p=0.045). CONCLUSION At midterm follow-up of patients treated for TASCII C/D femoropopliteal artery disease, use of DCB or of DCB combined with rescue BMS appeared similarly efficacious, and yielded more favorable outcomes than use of BMS. CLINICAL IMPACT The efficacy of drug-coated balloons relative to that of bare metal stents for the treatment of complex femoropopliteal artery lesions, particularly TASCII grade D lesions, remains uncertain. There is a scarcity of multicenter comparative studies, and in this multicenter retrospective study with up to 24-month follow-up, use of drug-coated balloon alone or combined with rescue bare metal stent appeared similarly efficacious while yielding more favorable outcomes than use of bare metal stent alone in the treatment of TASCII grade C/D femoropopliteal artery lesions. Randomized studies are warranted.

Abstract
BACKGROUND Randomized trials have shown comparable outcomes between second-generation low-dose drug-coated balloons (LD-DCBs) and first-generation high-dose drug-coated balloons (HD-DCBs); but the trial patients had low clinical complexity, and there were no comparisons in medically complex populations. OBJECTIVES The aim of this study was to compare outcomes between an LD-DCB (Ranger; 2.0 μg/mm2) and an HD-DCB (IN.PACT; 3.5 μg/mm2) in patients with symptomatic femoropopliteal artery disease. METHODS PROSPECT MONSTER (Prospective Comparison of Second-Generation Low-Dose Drug-Coated Balloon With High-Dose Drug-Coated Balloon) was a prospective, multicenter, nonrandomized trial that prospectively collected data from 581 patients who underwent endovascular therapy with the LD-DCB (n = 370) or the HD-DCB (n = 211) for symptomatic femoropopliteal artery disease (Rutherford classes 2-5). The primary outcome was the 1-year primary patency of the LD-DCB in comparison with that of the HD-DCB, as evaluated using propensity score matching. The incidence of impaired flow after drug-coated balloon application was also evaluated. RESULTS Propensity score matching extracted 163 pairs (358 and 163 patients in the LD-DCB and HD-DCB groups, respectively), with no significant intergroup difference in baseline characteristics. The 1-year primary patency rates in the matched population were similar between the LD-DCB and HD-DCB groups (87.0% [95% CI: 82.5%-91.7%] vs 81.3% [95% CI: 74.8%-88.5%]; HR: 0.93; 95% CI: 0.55-1.59; P = 0.79), as was the incidence of impaired flow (13.6% vs 9.8%; OR: 1.46; 95% CI: 0.78-2.73; P = 0.24). No baseline characteristics had any significant interaction effects on the association of the LD-DCB vs the HD-DCB and 1-year restenosis risk. CONCLUSIONS LD-DCBs demonstrate efficacy and safety comparable with HD-DCBs in patients with complex clinical backgrounds, suggesting that drug-coated balloon treatment using a lower dose may be possible.

Abstract
PURPOSE To evaluate 6-month outcomes of drug-coated balloon (DCB) angioplasty of infrapopliteal lesions in patients with chronic limb-threatening ischemia (CLTI). METHODS We analyzed 6-month follow-up data from the 10-center PRIME-WIFI prospective registry on 300 consecutive patients (33.000% female) with CLTI who underwent DCB angioplasty for infrapopliteal arterial lesions. The primary outcome was freedom from major adverse event (MAE), a composite of major amputation, all-cause death, and clinically-driven target limb reintervention (CD-TLR). Secondary outcomes included amputation-free survival (AFS), freedom from each primary outcome component, primary sustained clinical improvement, and quality of life (QOL) score. Independent risk factors of MAE were determined using Cox proportional hazards regression analysis. RESULTS A total of 409 infrapopliteal lesions in 312 limbs were treated with DCB, with 54.167% of the limbs being treated for isolated infrapopliteal lesions. By Kaplan-Meier analysis, at 6 months post- procedure (follow-up rate, 85.000%), freedom from MAE was 86.353%; AFS was 90.318%; and freedom from major amputation, all-cause death, and CD-TLR were 96.429%, 93.480%, and 95.079%, respectively. At 6-month follow-up, 83.590% of patients showed primary sustained clinical improvement, and QOL score (4.902±1.388) improved compared with that before procedure (2.327±1.109; p<0.001). Chronic renal insufficiency, chronic obstructive pulmonary disease, Rutherford grade, and postoperative infrapopliteal runoff score were independent risk factors for MAE within 6 months. CONCLUSION In CLTI, DCB angioplasty of infrapopliteal lesions yields acceptable early efficacy and safety. CLINICAL IMPACT This study evaluated the 6-month outcomes of DCB angioplasty in infrapopliteal lesions in CLTI patients by analyzing multicenter prospective data, showing that infrapopliteal DCB angioplasty can be performed with acceptable freedom from MAE rate, amputation-free survival rate, freedom from major amputation rate, survival rate, and freedom from CD-TLR rate. No patient experienced DCB-related intraoperative distal embolism. Chronic renal insufficiency, chronic obstructive pulmonary disease, Rutherford grade and postoperative infrapopliteal runoff score were independent risk factors for MAE within 6 months. Comparative real-world studies are needed.

Association of Preoperative Frailty with Inferior Outcomes for Patients Undergoing Lower Extremity Bypass for Chronic Limb Threatening Ischemia: A Systematic Review. Ann Vasc Surg 2023; 97:320-328. [PMID: 37356656 DOI: 10.1016/j.avsg.2023.05.044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Revised: 05/22/2023] [Accepted: 05/26/2023] [Indexed: 06/27/2023]
Abstract
BACKGROUND Frailty is a risk factor associated with adverse postoperative outcomes following lower extremity bypass (LEB) surgery in patients with peripheral arterial disease (PAD). Chronic limb threatening ischemia (CLTI) represents the worst form of PAD, and frailty is common among patients presenting with CLTI. Multiple frailty assessment scores have been developed for the past 2 decades; however, a universal clinical assessment tool for measuring frailty has not yet been established due to the complexity of the concept. This systematic review aimed to evaluate the use of a frailty index as a predictor of postoperative outcomes in patients undergoing LEB. METHODS The review protocol was registered in the international prospective register of systematic reviews (PROSPERO) database (CRD42022358888). A systematic literature search was conducted using the PubMed and Scopus databases. The review followed the preferred reporting items for systematic reviews and metaanalyses (PRISMA) guidelines. The risk of bias was evaluated using the Risk of Bias in Non-randomized Studies of Interventions (ROBINS-I) tool. A total of 3,929 studies were initially selected originally and were eventually left with 6 studies that met the inclusion criteria of this systematic review. RESULTS Six studies were examined that assessed the relationship between frailty index and long-term mortality following LEB for CLTI were screened. All analyses were published between 2017 and 2020 and included a broad spectrum of patients who underwent LEB. The results of these studies showed inconsistencies in the reporting of postoperative outcomes and the time endpoint of these events. However, all correlated with higher frailty index and increased mortality rate. CONCLUSIONS Higher frailty index preoperatively is associated with an increased likelihood of postoperative comorbidities after undergoing LEB. Identifying and addressing the preoperative frailty index of these patients may be a practical approach to reducing postoperative adverse outcomes. A thorough review of the frailty spectrum and standardized reporting of outcomes in the context of frailty could be helpful to have a more comprehensive understanding of this subject.

Use of Omniflow® II Biosynthetic Graft for the Treatment of Vascular Graft and Endograft Infections. Ann Vasc Surg 2023; 97:410-418. [PMID: 37244480 DOI: 10.1016/j.avsg.2023.05.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2023] [Revised: 05/15/2023] [Accepted: 05/15/2023] [Indexed: 05/29/2023]
Abstract
BACKGROUND Vascular graft/endograft infection is a rare but life-threatening complication of cardiovascular surgery and remains a surgical challenge. Several different graft materials are available for the treatment of vascular graft/endograft infection, each having its own advantages and disadvantages. Biosynthetic vascular grafts have shown low reinfection rates and could be a potential second best after autologous veins in the treatment of vascular graft/endograft infection. Therefore, the aim of our study was to evaluate the efficacy and morbidity of Omniflow® II for the treatment of vascular graft/endograft infection. METHODS A multicenter retrospective cohort study was performed to evaluate the use of Omniflow® II in the abdominal and peripheral region to treat vascular graft/endograft infection between January 2014 and December 2021. Primary outcome was recurrent vascular graft infection. Secondary outcomes included primary patency, primary assisted patency, secondary patency, all-cause mortality, and major amputation. RESULTS Fifty-two patients were included with a median follow-up duration of 26.5 (10.8-54.8) months. Nine (17%) grafts were implanted in intracavitary position and 43 (83%) in peripheral position. Most grafts were used as femoral interposition (n = 12, 23%), femoro-femoral crossover (n = 10, 19%), femoro-popliteal (n = 8, 15%), and aorto-bifemoral (n = 8, 15%) graft. Fifteen (29%) grafts were implanted extra-anatomically and 37 (71%) in situ. Eight patients (15%) presented with reinfection during follow-up, most of these patients received an aorto-bifemoral graft (n = 3, 38%). Intracavitary vascular grafting had a 33% (n = 3) reinfection rate and peripheral grafting 12% (n = 5; P = 0.025). The estimated primary patencies at 1, 2, and 3 years were 75%, 72%, and 72% for peripherally located grafts and 58% (at all timepoints) for intracavitary grafts (P = 0.815). Secondary patencies at 1, 2, and 3 years were 77% (at all timepoints) for peripherally located prostheses and 75% (at all timepoints) for intracavitary prostheses (P = 0.731). A significantly higher mortality during follow-up was observed in patients who received an intracavitary graft compared to patients with a peripheral graft (P = 0.003). CONCLUSIONS This study highlights the efficacy and safety of the Omniflow® II biosynthetic prosthesis for the treatment of vascular graft/endograft infection, in absence of suitable venous material, with acceptable reinfection, patency, and freedom of amputation prevalences, especially in replacing peripheral vascular graft/endograft infection. However, a control group with either venous reconstruction or another alternative graft is needed to make firmer conclusions.

Abstract
PURPOSE To evaluate endovascular popliteal artery aneurysm repair using a an "off-label" abdominal endograft limb-module with nitinol-ring structure. MATERIALS AND METHODS Retrospective observational study of 14 popliteal artery aneurysms in 12 male patients (mean age 76 years and median ASA grade 3) treated electively using the Anaconda™ endograft limb (Terumo Aortic) at a single teaching hospital. Eight limbs were treated percutaneously and 6 limbs required surgical arterial exposure. The mean popliteal artery aneurysm diameter treated was 3.6 cm (range 2.1-5.3 cm). Stent-graft diameters and lengths used were 10-15 and 60-140 mm, respectively. The median covered stented length was 218 mm (range 160-270 mm) and median duration of follow-up was 3.7 years. Outcomes assessed included technically successful aneurysm exclusion, primary patency, re-intervention and survival. RESULTS All patients had successful stent-graft deployment and aneurysm exclusion, with no early complications or mortality at 30 days. Primary stent-graft patency at 1, 3 and 4 years was 93%, 75%, and 64%. By 8 years, patency had declined with 29% (2/14) stent-grafts patent. 7/14 limbs occluded; 3 underwent re-intervention (2 surgical, 1 endovascular). There were no deaths related to the procedure. Freedom from re-intervention and survival at 1/5 years was 93%/84% and 93%/67%, respectively. CONCLUSION The Anaconda™ endograft limb for endovascular popliteal artery aneurysm repair offers good mid-term patency and acceptable long-term patency up to 4 years when compared with other grafts and open surgery. It may be considered in older comorbid patients unfit for surgery and can be performed percutaneously under local anaesthesia when anatomically feasible.

Abstract
OBJECTIVE Prior research has shown that socioeconomic status (SES) is associated with higher rates of diabetes, peripheral vascular disease, and amputation. We sought to determine whether SES or insurance type increases the risk of mortality, major adverse limb events (MALE), or hospital length of stay (LOS) after open lower extremity revascularization. METHODS We conducted a retrospective analysis of patients who underwent open lower extremity revascularization at a single tertiary care center from January 2011 to March 2017 (n = 542). SES was determined using state Area Deprivation Index (ADI), a validated metric determined by income, education, employment, and housing quality by census block group. Patients undergoing amputation in this same time period (n = 243) were included to compare rates of revascularization to amputation by ADI and insurance status. For patients undergoing revascularization or amputation procedures on both limbs, each limb was treated individually for this analysis. We performed a multivariate analysis of the association between ADI and insurance type with mortality, MALE, and LOS using Cox proportional hazard models, including confounding variables such as age, gender, smoking status, body mass index, hyperlipidemia, hypertension, and diabetes. The cohort with an ADI quintile of 1, meaning least deprived, and the Medicare cohort were used for reference. P values of <.05 were considered statistically significant. RESULTS We included 246 patients undergoing open lower extremity revascularization and 168 patients undergoing amputation. Controlling for age, gender, smoking status, body mass index, hyperlipidemia, hypertension, and diabetes, ADI was not an independent predictor of mortality (P = .838), MALE (P = .094), or hospital LOS (P = .912). Controlling for the same confounders, uninsured status was independently predictive of mortality (P = .033), but not MALE (P = .088) or hospital LOS (P = .125). There was no difference in the distribution of revascularizations or amputations by ADI (P = .628), but there was higher proportion of uninsured patients undergoing amputation compared with revascularization (P < .001). CONCLUSIONS This study suggests that ADI is not associated with an increased risk of mortality or MALE in patients undergoing open lower extremity revascularization, but that uninsured patients are at higher risk of mortality after revascularization. These findings indicate that individuals undergoing open lower extremity revascularization at this single tertiary care teaching hospital received similar care, regardless of their ADI. Further study is warranted to understand the specific barriers that uninsured patients face.

Abstract
BACKGROUND AND AIMS Endovascular recanalizaiton (ER) has been proven to be a feasible method for Thromboangiitis Obliterans (TAO). The aims of this study were to evaluate the effectiveness and safety of atherectomy for TAO compared to nonatherectomy ER in our center. METHODS Patients diagnosed as TAO were reviewed from January 2016 to June 2021 in our center. Basic characteristics of patients before ER and perioperative data were collected and compared between the atherectomy and nonatherectomy groups. The vascular event-free survival and limb salvage were calculated to evaluate the prognosis of TAO patients after ERs. Logistic Regression and Cox Regression were used to identify the risk factors for technical failure and prognosis, respectively. RESULTS Seventy-two TAO patients with 79 lower limbs who met the criteria were included in this report. Compared with the nonatherectomy group, no significant improvement was identified in ER technical success, vascular event-free survival, or limb salvage in the atherectomy group. The total technical success rate was 91.1% (atherectomy group, 95.2%; nonatherectomy group, 89.7%), and the multiple limb involvement (p = 0.005; odds ratio [OR], 28.16; confidence interval [CI], 3.28-241.55) was the independent risk factor for technical failure. The total vascular event-free survival proportion was 66.05% and 58.40% at 1 and 3 years, respectively. Technical failure (OR, 5.61; 95% CI, 1.57-20.04; p = 0.008), and runoff grade 0 (OR, 3.28; 95% CI, 1.09-9.85; p = 0.034) were independent risk factors for vascular events. The total limb salvage proportion at 1 and 3 years was 95.84% and 92.53%, respectively. Technical failure (OR, 8.54; 95% CI, 1.71-40.73; p = 0.02) was identified as an independent risk factor for above ankle amputation. CONCLUSIONS No significant difference in prognosis was found between the atherectomy group and the nonatherectomy group during a midterm follow-up. The technical success of ER was crucial for TAO prognosis.

Abstract
Clinical trials have demonstrated the efficacy of a balloon-expandable covered stent (CS) for aortoiliac occlusive disease (AIOD). However, the real-world clinical outcomes and the underlying factors remain unclear. We assessed the clinical outcomes and factors associated with primary patency after implantation of a balloon-expandable CS for patients with complex AIOD. This prospective multicenter observational study enrolled 149 consecutive patients undergoing VIABAHN® VBX-CS (W.L. Gore & Associates, Flagstaff, AZ) implantation for complex AIOD (age, 74 ± 9 years; male, 74%; diabetes mellitus, 46%; renal failure on dialysis, 23%; chronic limb-threatening ischemia, 26%). The primary study endpoint was 1-year primary patency, and the secondary endpoints were procedural complications, freedom from occlusion, clinical-driven target lesion revascularization (CD-TLR), and surgical revision at 1 year. Risk factors for restenosis were explored using random survival forest analysis. The median follow-up period was 13.1 months (interquartile range 9.7-14.0 months). Procedural complications were observed in 6.7% of the patients. The 1-year primary patency was 94.8% (95% confidence interval 91.0-98.6%), while the 1-year freedom rate from occlusion, CD-TLR, and surgical revision rates were 96.5% (93.5-99.5%), 94.7% (90.9-98.6%), and 97.8% (95.4-100%), respectively. The presence of chronic total occlusion, aortic bifurcation lesion, the number of disease regions, and TASC-II classification was significantly associated with the restenosis risk. In contrast, the calcification severity, IVUS use, IVUS parameters were not associated with restenosis risk. We observed excellent 1-year real-world outcomes after implantation of a balloon-expandable CS for complex AIOD; only a few perioperative complications occurred.

Abstract
OBJECTIVE Drug eluting stents (DES) might improve the results of stenting in the femoropopliteal (FP) segment, but randomized data between DES and BMS in the treatment of patients with chronic limb threatening ischemia (CLTI) is lacking. The aim of this study was to perform a randomized comparison, between DES and bare metal stent (BMS) implantation in a subgroup of CLTI patients with lesions in the superficial femoral artery (SFA) and the P1-P2 portion of the popliteal artery. METHODS Patients presenting with CLTI scheduled for endovascular treatment of FP lesions were randomly assigned by blinded envelopes 1:1 in a single blinded, parallel group design to DES or BMS after lesion crossing. Primary endpoints were target lesion revascularization (TLR) at 12 and 24 months and primary patency at 12 and 24 months. Secondary endpoints were technical success (TS), clinical success, secondary patency at 12 and 24 months, limb salvage, serious adverse events (SAE) at 24 month and survival at five years. RESULTS A total of 48 CLTI patients and 49 limbs, were enrolled, 22 in the BMS group and 27 in the DES group. Demographics, comorbidities, and Rutherford class were similar in both treatment arms. The overall rate of total occlusions was 96% and the corresponding overall median lesion length was 240 mm. No patients were lost to follow up. No significant differences were detected between groups regarding TLR and primary patency. The overall primary patency at 12 and 24 months was 42.9% and 36.7% respectively and the overall freedom from TLR was 67.3% and 61.2% respectively. The results in the two groups were also similar regarding secondary outcomes. CONCLUSIONS This single centre, randomized study could not demonstrate superiority of DES compared to BMS when treating long FP lesions in patients with CLTI but was limited by insufficient patient inclusion.

Abstract
PURPOSE This study examines the use and impact of directional atherectomy with antirestenotic therapy (DAART) versus angioplasty plus Supera stent implantation on the outcomes during endovascular treatment of popliteal lesions in clinical practice. METHODS Overall 143 consecutive patients (mean age 75.0±12.2 years, 72% male), with isolated atherosclerotic disease of the popliteal artery who underwent endovascular treatment using DAART therapy or percutaneous transluminal angioplasty (PTA)/Supera stenting of the popliteal artery between January 2016 and December 2021 were identified from a retrospectively database. Patient and plaque characteristics were collected. A propensity-score matched, case-control analysis was conducted to balance covariates between the group of patients who underwent DAART and the one treated by PTA/Supera stenting. RESULTS A total of 51 patients (35.7%) showed severe claudication and 92 (64.3%) critical limb ischemia. There was a trend toward longer treated lesions (90.4±81 vs 72.5±5.3 mm, p=0.089) and more chronic total occlusions (60.5% vs 46.8%, p=0.058) in the PTA/Supera stenting group, although not reaching statistically significance. Moderate-to-severe calcification was present in most lesions treated (75.8% of DAART group, 80.2% of PTA/Supera stenting group, and 78.3% of total cohort). Among the 53 case-matched pairs of patients treated with DAART or PTA/Supera stenting, there were no significant differences in short-term outcomes, including rate of technical success (96.2% vs 98.1%, p=0.232), procedural success (88.7% vs 90.1%, p=0.251), distal embolization (1.9% vs 1.9%, p=0.178), dissection (5.7% vs 1.9%, p=0.268), perforation (3.8% vs 5.6%, p=0.163), hospital discharge (1.2±0.1 vs 1.0±0.1, p=0.325), 30 day minor (28.3% vs 32.1%, p=0.264) or major amputation rates (7.5% vs 3.8%, p=0.107), and 30 day mortality (1.9% vs 1.9%, p=0.173). At 1 year, there was no difference in primary patency (73.6% vs 77.4%, p=0.233), primary assisted patency (81.3% vs 84.9%, p=0.167), secondary patency (86.8% vs 92.5%, p=0.094), ipsilateral minor (35.8% vs 39.6%, p=0.472) or major amputation (9.4% vs 7.5%, p=0.186), ankle brachial index improvement (0.32±0.12 vs 0.37±0.37, p=0.401), or mortality (5.7% vs 5.7%, p=0.121) rate between patients who underwent DAART or PTA/Supera stenting for popliteal lesions. CONCLUSION Twelve-month results following DAART technique or PTA/Supera stenting of atherosclerotic lesions of the popliteal artery are not different, regardless of patient and plaque characteristics. CLINICAL IMPACT The DAART technique for the treatment of popliteal artery atherosclerotic disease is presented as a "leave nothing behind" strategy with on-year clinical outcomes similar to ATP/Supera stenting.
