Abstract
BACKGROUND Current endovascular treatments of below the knee (BTK) popliteal or tibial/peroneal arteries including investigational drug-coated balloons have limited long-term efficacy. OBJECTIVES This Phase 2 trial assessed the feasibility of adventitial deposition of temsirolimus to reduce neointimal hyperplasia and clinically relevant target lesion failure (CR-TLF) 6 months after BTK arterial revascularization. METHODS This prospective, multicenter, double-blinded, comparative, dose-escalation trial enrolled 61 patients with Rutherford 3 to 5 symptoms undergoing endovascular revascularization of ≥1 angiographically significant BTK lesions. Perivascular infusion after completion of arterial revascularization was randomized into control (saline) vs low-dose (0.1 mg/mL) temsirolimus groups for the first 30 patients. In the second part of the trial, patients were randomized to control versus high-dose (0.4 mg/mL) temsirolimus groups. Primary and secondary efficacy endpoints were target lesion (TL) transverse-view vessel area loss percentage (TVAL%) and CR-TLF at 6 months, respectively. CR-TLF was defined as a composite of ischemia-driven major amputation of the target limb, clinically driven target lesion revascularization (CD-TLR), and clinically relevant TL occlusion. The primary safety endpoint was freedom from major adverse limb events or perioperative death (MALE+POD) at 30 days. RESULTS There was no discernable difference in effect between temsirolimus doses; therefore, the low- and high-dose cohorts were pooled for the analyses. The principal analysis on the per protocol (PP) group of 53 patients revealed superior primary efficacy of the treatment arm, with reduction in TVAL% of 13.9% absolute (37.3% relative) and the rate of CR-TLF reduced by 27.1% absolute (51.3% relative), at 6 months. Subgroup analysis of all Trans-Atlantic Inter-Society Consensus (TASC) B to D lesions (N=36) revealed TVAL% reduction of 22.3% absolute (48.3% relative) and the rate of CR-TLF reduced by 39.2% absolute (56.6% relative). Freedom from 30-day MALE+POD was 100% in all groups. CONCLUSIONS This hypothesis-generating trial suggests that adventitial infusion of temsirolimus in BTK arteries improves TVAL% and CR-TLF with no adverse safety signals through 6 months, supporting the move to a Phase 3 trial. CLINICAL IMPACT There remain gaps in the endovascular treatment of patients with atherosclerotic lesions of below-the-knee (BTK) arteries. The TANGO trial evaluated the use of sub-adventitial temsirolimus with the Bullfrog micro-infusion device during BTK interventions. The therapy was safe and effective. Compared with controls, vessel lumen area patency was improved, and target lesion failure was less frequent. The effects were most appreciable in subjects with higher baseline TASC lesions (B, C, or D). Sub-adventitial temsirolimus offers the potential to improve the results of BTK interventions in this challenging patient population.

Mechanical, structural, and physiologic differences between above and below-knee human arteries. Acta Biomater 2024; 177:278-299. [PMID: 38307479 DOI: 10.1016/j.actbio.2024.01.040] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2023] [Revised: 01/07/2024] [Accepted: 01/25/2024] [Indexed: 02/04/2024]
Abstract
Peripheral Artery Disease (PAD) affects the lower extremities and frequently results in poor clinical outcomes, especially in the vessels below the knee. Understanding the biomechanical and structural characteristics of these arteries is important for improving treatment efficacy, but mechanical and structural data on tibial vessels remain limited. We compared the superficial femoral (SFA) and popliteal (PA) arteries that comprise the above-knee femoropopliteal (FPA) segment to the infrapopliteal (IPA) anterior tibial (AT), posterior tibial (PT), and fibular (FA) arteries from the same 15 human subjects (average age 52, range 42-67 years, 87 % male). Vessels were imaged using μCT, evaluated with biaxial mechanical testing and constitutive modeling, and assessed for elastin, collagen, smooth muscle cells (SMCs), and glycosaminoglycans (GAGs). IPAs were more often diseased or calcified compared to the FPAs. They were also twice smaller, 53 % thinner, and significantly stiffer than the FPA longitudinally, but not circumferentially. IPAs experienced 48 % higher physiologic longitudinal stresses (62 kPa) but 27 % lower circumferential stresses (24 kPa) and similar cardiac cycle stretch of <1.02 compared to the FPA. IPAs had lower longitudinal pre-stretch (1.12) than the FPAs (1.29), but there were no differences in the stored elastic energy during pulsation. The physiologic circumferential stiffness was similar in the above and below-knee arteries (718 kPa vs 754 kPa). Structurally, IPAs had less elastin, collagen, and GAGs than the FPA, but maintained similar SMC content. Our findings contribute to a better understanding of segment-specific human lower extremity artery biomechanics and may inform the development of better medical devices for PAD treatment. STATEMENT OF SIGNIFICANCE: Peripheral Artery Disease (PAD) in the lower extremity arteries exhibits distinct characteristics and results in different clinical outcomes when treating arteries above and below the knee. However, their mechanical, structural, and physiologic differences are poorly understood. Our study compared above- and below-knee arteries from the same middle-aged human subjects and demonstrated distinct differences in size, structure, and mechanical properties, leading to variations in their physiological behavior. These insights could pave the way for creating location-specific medical devices and treatments for PAD, offering a more effective approach to its management. Our findings provide new, important perspectives for clinicians, researchers, and medical device developers interested in treating PAD in both above- and below-knee locations.

Heparin-Bonded Expanded Polytetrafluoroethylene Is a Solution for Infrapopliteal Revascularization in the Absence of an Adequate Autologous Vein Graft. Ann Vasc Surg 2024; 98:201-209. [PMID: 37355019 DOI: 10.1016/j.avsg.2023.06.015] [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: 04/16/2023] [Revised: 06/05/2023] [Accepted: 06/09/2023] [Indexed: 06/26/2023]
Abstract
BACKGROUND To analyze the outcomes of heparin-bonded expanded polytetrafluoroethylene (HePTFE) graft as an alternative conduit in infrapopliteal revascularization of chronic limb-threatening ischemia (CLTI) in the absence of an autologous vein conduit. METHODS A single-center retrospective analysis of patients with CLTI submitted to infrapopliteal bypasses with autologous vein graft (VEIN group) or HePTFE graft (HePTFE group) was implemented. Primary end points were freedom from CLTI at 12 months and recurrence of CLTI at 3 years. Secondary end points included freedom from major amputation, amputation-free survival (AFS), survival, and primary (PP) and secondary patency (SP) rates at 3 years of follow-up. RESULTS A total of 348 limbs submitted to infrapopliteal bypasses, 214 with venous graft and 134 with HePTFE graft, were followed-up for a median of 25 months. Most patients of the HePTFE group were male (69%), with a median age of 76 years (interquartile range [IQR] 15). Fifty-nine percent of the limbs of the HePTFE group had Wound grade ≥2, being 46% of them infected. Eighty-eight percent were GLASS stage III. Freedom from CLTI was not significantly different between HePTFE and VEIN groups (75% vs. 84%, adjusted hazard ratio [aHR] 0.88, confidence interval [CI] 0.66-1.18, P = 0.401). Recurrence of CLTI was higher in the HePTFE group (42% vs.18% at 3 years; aHR 2.82, CI 1.59-5.00, P < 0.001). The VEIN group achieved higher rates of freedom from major amputation (87% vs.69% at 3 years; aHR 2.21, CI 1.31-3.75, P = 0.003) and AFS (59% vs. 37% at 3 years; aHR 1.39, CI 1.02-1.88, P = 0.036), but no significance in survival (aHR 1.10, CI 0.72-1.66, P = 0.667). Patency rates were inferior in the HePTFE group, with 2-year PP and SP rates of 52% vs. 74%, and 76% vs. 90%, respectively (PP: aHR 1.70, CI 1.11-2.59, P = 0.014; SP: aHR 2.51, CI 1.42-4.42, P = 0.001). CONCLUSIONS Infrapopliteal bypass with autologous vein graft is the gold standard to treat CLTI limbs. HePTFE graft should be regarded as an alternative for complex infrapopliteal revascularization when lacking an autologous vein conduct.

Abstract
BACKGROUND Endovascular treatment (EVT) has replaced open repair as the first option in intermittent claudication (IC) and chronic limb-threatening ischemia (CLTI) in several centers. However, evidence of the most optimal post-procedural surveillance strategy is sparse. This study aimed to compare two routine surveillance programs after EVT of IC/CLTI: clinical and hemodynamic assessment (CHA) vs. duplex ultrasound (DUS) and clinical/hemodynamic assessment in combination. METHODS Between February 2012 and December 2015, all patients with EVT of IC/CLTI were allocated to either CHA or DUS-based routine surveillance programs. The allocation-ratio was 1:2 (CHA:DUS), and propensity score matching (PSM) was used to control baseline differences between the groups. Follow-up visits in the CHA group consisted of clinical assessment and ABI at 3, 6, 12 and 24 months. Follow-up visits in DUS group consisted of clinical assessment, ABI, and target vessel DUS at 1, 3, 6, 12, 18 and 24 months. RESULTS In total, 340 legs in 305 patients suffering from IC/CLTI were included; 111 (33%) in the CHA-group and 229 (67%) in the DUS group. The two groups were identical except for a significantly lower incidence of diabetes mellitus in the CHA group than the DUS group, 55% vs. 72%, respectively (P=006). Based on PSM, the CHA-group vs. the DUS-group was burdened of an increased risk of amputation (12.5% vs. 8.27%, HR=0.41 [95% CI: 0.17-0.96]), and a higher mortality (21.2% vs. 12.8%, HR=0.37 [95% CI: 0.19-0.72]). The reported differences in reintervention rate (7.5% vs. 12.8%, HR=1.12 [95% CI: 0.44-2.84]) were insignificant. The mean follow-up was 317 days (SD=0.214) in the CHA group and 611 days (SD=0.298) in the DUS group. CONCLUSIONS Our results suggest that DUS-based routine surveillance after EVT of IC/CLTI is superior to CHA-based routine surveillance in improved amputation rate and mortality.

Abstract
There are few studies on excimer laser (308 nm) atherectomy in the treatment of infrapopliteal artery disease. The purpose of this retrospective clinical study was to assess the efficacy and safety of excimer laser atherectomy (ELA) in combination with adjuvant drug-coated balloon angioplasty (DCB) compared to DCB for infrapopliteal arterial revascularization in patients with ischemic diabetic foot. From September 2018 to February 2019, a total of 79 patients with diabetic foot were treated for infrapopliteal arterial revascularization at Tianjin First Central Hospital (Tianjin, China). In this project, 35 patients were treated with ELA combined with DCB angioplasty, and 44 patients were treated with DCB angioplasty. The patients' baseline characteristics were similar between the 2 groups. The primary efficacy endpoints through 24 months were clinically driven target lesion revascularization (CD-TLR), wound healing rate, major amputation rate, and target vessel patency rate. The primary safety endpoint through 24 months was all-cause mortality. The primary efficacy results at 24 months of ELA + DCB versus DCB were CD-TLR of 14.3% versus 34.1% (p = 0.044), wound healing rate of 88.6% versus 65.9% (p = 0.019), target vessel patency rate of 80.0% versus 52.3% (p = 0.010), and major amputations rate of 5.7% versus 22.7% (p = 0.036). The safety signal at 24 months of all-cause mortality rate was 2.9% for ELA + DCB group and 4.5% for DCB group (p = 0.957). ELA combined with DCB angioplasty is more effective than DCB in the treatment of infrapopliteal artery disease in patients with ischemic diabetic foot, which can improve the wound healing rate and target vessel patency rate. There was no statistical difference in the safety results between the two groups.

Abstract
Chronic limb-threatening ischemia (CLTI) is the most severe form of peripheral artery disease. It is estimated that 60% of all nontraumatic lower-extremity amputations performed annually in the United States are in patients with diabetes and CLTI. The consequences of this condition are extraordinary, with substantial patient morbidity and mortality and high socioeconomic costs. Strategies that optimize the success of arterial revascularization in this unique patient population can have a substantial public health impact and improve patient outcomes. This article provides an up-to-date comprehensive assessment of management strategies for patients afflicted by both diabetes and CLTI.

Abstract
Background There is a paucity of randomized trials demonstrating superior efficacy of drug-coated balloon angioplasty (DCBA) compared with conventional percutaneous transluminal angioplasty (PTA) for below-the-knee arterial disease in patients with -critical limb ischemia. Purpose To compare DCBA versus PTA for below-the-knee lesions in participants with critical limb ischemia through 12 months. Materials and Methods In this prospective, randomized, two-center, double-blind superiority study, participants with critical limb ischemia with rest pain or tissue loss with atherosclerotic disease in the native below-the-knee arteries were randomly assigned (in a one-to-one ratio) to DCBA or PTA after stratification for diabetes and renal failure between November 2013 and October 2017. The primary efficacy end point was angiographic primary patency at 6 months analyzed on an intention-to-treat basis. Secondary end points through 12 months were composed of major adverse events including death and major amputations, wound healing, limb salvage, clinically driven target-lesion revascularization, and amputation-free survival. Primary and binary secondary end points, analyzed by using generalized-linear model and time-to-event analyses, were estimated with Kaplan-Meier survival curves and hazard ratios (Cox regression). Results Seventy participants (mean age, 61 years ± 10 [standard deviation]; 43 men) in the DCBA group and 68 (mean age, 64 years ± 10; 50 men) in the PTA group were evaluated. The percentage of patients with angiographic primary patency at 6 months was 43% (30 of 70) in the DCBA group and 38% (26 of 68) in the PTA group (P = .48). Through 12 months, the percentage of deaths was similar: 21% in the DCBA group and 16% in the PTA group (P = .43). Amputation-free survival rate assessed with Kaplan-Meier curves differed through 12 months: 59% (41 of 70) in the DCBA group compared with 78% (53 of 68) in the PTA group (P = .01). Conclusion In participants with critical limb ischemia, the drug-coated balloon angioplasty group and the conventional percutaneous transluminal angioplasty group had similar primary patency rates at 6 months after treatment of below-the-knee arteries. Amputation-free survival rates through 12 months were higher in the percutaneous transluminal angioplasty group. © RSNA, 2021 Online supplemental material is available for this article.

Effect of Direct Endovascular Revascularization Based on the Angiosome Model on Risk of Major Amputations and Life Expectancy in Type 2 Diabetic Patients with Critical Limb Ischemia and Foot Ulceration.

Abstract
BACKGROUND We evaluated whether direct or indirect endovascular revascularization based on the angiosome model affects outcomes in type 2 diabetes and critical limb ischemia. METHODS From 2010 to 2015, 603 patients with type 2 diabetes were admitted for critical limb ischemia and submitted to endovascular revascularization. Among these patients, 314 (52%) underwent direct and 123 (20%) indirect revascularization, depending on whether the flow to the artery directly feeding the site of ulceration, according to the angiosome model, was successfully acquired; 166 patients (28%) were judged unable to be revascularized. Outcomes were healing, major amputation, and mortality rates. RESULTS An overall healing rate of 62.5% was observed: patients who did not receive percutaneous transluminal angioplasty presented a healing rate of 58.4% (P < .02 versus revascularized patients). A higher healing rate was observed in the direct versus the indirect group (82.4% versus 50.4%; P < .001). The major amputation rate was significantly higher in the indirect versus the direct group (9.2% versus 3.2%; P < .05). The overall mortality rate was 21.6%, and it was higher in the indirect versus the direct group (24% versus 14%; P < .05). CONCLUSIONS These data show that direct revascularization of arteries supplying the diabetic foot ulcer site by means of the angiosome model is associated with a higher healing rate and lower risk of amputation and death compared with the indirect procedure. These results support use of the angiosome model in type 2 diabetes with critical limb ischemia.

Abstract
INTRODUCTION The past 25 years have been witness to a revolution in how vascular care is delivered. The majority of arterial and venous interventions have converted from open surgery to minimally invasive percutaneous endovascular procedures. METHODS This surgical innovations symposium article reviews current endovascular therapy in multiple vascular beds with a primary focus on carotid artery occlusive disease, aortic pathologies, and lower extremity arterial occlusive disease. Mesenteric arterial occlusive disease and lower extremity venous endovascular therapies are also briefly discussed. Indications for intervention, treatment examples and outcomes analysis are presented. While not reviewed in this article, endovascular therapy has also become first line in the treatment of coronary artery disease, chronic mesenteric arterial occlusive disease, superficial venous reflux, central vein occlusion, and acute venous thrombus intervention when indicated. CONCLUSION Endovascular therapies are used in all vascular beds to treat the full spectrum of vascular pathologies. Aneurysm disease, atherosclerotic arterial occlusive disease, acute arterial and venous thrombosis, ongoing hemorrhage, and venous reflux are among the issues which can be addressed by endovascular means. The minimally invasive nature of endovascular treatments in what is largely a very co-morbid patient cohort is an attractive method of avoiding major procedural related morbidity and mortality.

Abstract
BACKGROUND To evaluate the safety, feasibility and effectiveness of high-pressure, noncompliant balloon angioplasty in the management of long infrapopliteal calcified lesions. METHODS Consecutive patients, presenting with chronic limb-threatening ischemia (CLTI) and long (>100 mm) calcified infrapopliteal lesions who were treated with a high pressure, noncompliant balloon (JADE, OrbusNeich, Hong Kong) between January 2016 and July 2016 were retrospectively analyzed. Angioplasty was performed by inflating the balloon to a pressure of 22 to 24 atm for 90 seconds. Primary outcome was technical success. Secondary outcomes were procedure-related complications, limb salvage, amputation-free survival (AFS), wound healing, overall survival, freedom from clinically driven target lesion reintervention (CD-TLR), and resolution of CLTI at 2 and 3 years. RESULTS Overall, 23 lesions in 21 limbs of 20 patients were treated. All patients had tissue loss (Rutherford 5 or 6). The mean lesion length was 374.8 mm. Of all lesions, 56.5% were occlusions, 91.3% were classified as TransAtlantic Inter-Society Consensus (TASC) C and D lesions, and 78.3% had severe calcification classification. Of all lesions, 52.2% extended into the below-the-ankle arteries. Technical success was achieved in 22 lesions (95.7%). There were no procedure-related complications. No bailout stenting was required. At 2 and 3 years, limb salvage was 84.7% and 78.7%, AFS was 71.4% and 56.1%, wound healing was 81.0% and 85.7%, overall survival was 75.0% and 64.3% and freedom from CD-TLR was 77.6% and 63.5%, respectively. Resolution of CLTI without TLR was 81.0% at 2 and 3 years. CONCLUSIONS This study is the first to analyze safety and feasibility of a high-pressure, noncompliant balloon for long, calcified infrapopliteal and inframalleolar lesions.

Abstract
BACKGROUND Extensive infrainguinal arterial disease still pose a challenge for technical and clinical success of percutaneous angioplasty. The purpose of this study was to compare the results of concomitant femoropopliteal and infrapopliteal percutaneous angioplasty/stenting (PTA/S) with distal bypass graft surgery (BGS) in patients with chronic limb-threatening ischemia (CLTI). METHOD In a single-center retrospective investigation between 2011 and 2017, 668 revascularization procedures for CLTI were reviewed. Concomitant femoropopliteal and infrapopliteal disease was identified in 153 CLTI patients, treated with BGS (48) using autogenous veins as substitute or PTA/S in a single procedure (105). A subgroup of patients with complex, extensive arterial lesions (GLASS stage III) received additional analysis. Primary outcomes were limb salvage and survival. RESULTS The mean follow-up time was 21.4 months. Patients treated with PTA/S were significantly older and with predominance of females, diabetes and chronic kidney disease. Smoking was more common in patients treated with BGS. The BGS group showed a 36-month survival rate of 73.4%, whereas the PTA/S group presented a survival of 61.3% in the same interval (P = 0.25). The 36-month cumulative limb salvage rate was 53.3 and 59.7% for BGS and PTA/S, respectively (P = 0.24). For GLASS stage III patients, 36-month limb salvage rates were 54.4% for the PTA/S group and 50.2% for the BGS group (P = 0.29). Multivariate analysis pointed poor runoff status (all endovascular patients) and diabetes (GLASS III endovascular patients) as risk factors for limb loss. CONCLUSION PTA/S and BGS presented similar results of limb salvage and survival in the treatment of concomitant femoropopliteal and infrapopliteal arterial disease in patients with CLTI, even for patients with extensive and complex arterial disease.

Abstract
In the absence of feasible revascularization, nearly one third of patients with critical limb ischemia experienced major amputation at 6 months. In patients with an independent living status, this decision is difficult to support without exhausting all chances to attain limb salvage and preserve functional autonomy. The present report describes a new procedure of revascularization by performing a full endovascular extra-anatomic femoropopliteal bypass for the treatment of limb-threatening ischemia. The patient presented with extensive tissue loss and a short-term risk of major amputation. She had experienced previous failure of conventional surgical and endovascular revascularization procedures and ligation of proximal femoral artery precluded any further revascularization attempt. Limb salvage was achieved with this endovascular revascularization procedure with complete wound closure. The patient still presents an independent living status and preserved functional autonomy without wound recurrence after a follow-up of more than 5 years.

Abstract
Introduction The role of atherectomy (ATHERO) for the treatment of symptomatic infra-inguinal arterial lesions remains controversial. We evaluated the effectiveness and safety of atherectomy-assisted endovascular interventions in comparison with percutaneous angioplasty (PTA). Material and methods A systematic search utilizing MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials was conducted for studies comparing ATHERO with PTA from February 1995 to May 2018. Only studies comparing ATHERO to PTA for symptomatic infra-inguinal disease were included. Random-effects meta-analysis was used to pool the data and endpoints across studies. Study endpoints included vessel dissection, distal embolization, residual stenosis (> 30%), vessel patency at 6 months, target lesion revascularization (TLR) at 12 months and major amputation rates at 1, 6, and 12 months. Results A total of 2923 patients were included from 8 studies. PTA was associated with higher vessel dissection (OR = 4.00, 95% CI: 1.15–13.86) and lower 12-month major amputation rates (OR = 0.73, 95% CI: 0.59–0.90). There was no significant difference between ATHERO and PTA groups in terms of distal embolization (OR = 0.45, 95% CI: 0.04–4.63), residual stenosis (OR = 1.28, 95% CI: 0.58–2.80), vessel patency at 6 months (OR = 1.27, 95% CI: 0.50–3.22), TLR at 12 months (OR = 1.07, 95% CI: 0.46–2.51), or limb amputation at 1 month (OR = 0.69, 95% CI: 0.44–1.07) or 6 months (OR = 1.54, 95% CI: 0.38–6.15). Conclusions In patients undergoing infra-inguinal endovascular interventions, PTA was associated with higher peri-procedural vessel dissection and lower 12-month major amputation rates. Both modalities were associated with similar distal embolization, residual stenosis, and 6-month vessel patency and amputation rates.

Abstract
Critical limb ischemia represents the end stage of peripheral artery disease, which is associated with impaired quality of life and considerable morbidity and mortality. Economical impact of the disease is huge with a substantial burden on patients, healthcare providers, and resources. Varied therapeutic strategies have been employed in the management of these patients. These patients usually have complex multilevel occlusive arteriopathy with significant comorbidities, rendering surgical interventions undesirable in many cases. Recent therapeutic advances with evolving endovascular techniques and gene or cell-based therapies have the potential to dramatically change the therapeutic outlook in these patients.

Abstract
Aim: Previous studies on peripheral artery disease (PAD) only enrolled patients with atherosclerotic lesion limited to any one of isolated locations (aortoiliac [AI], femoropopliteal [FP], and below the knee [BTK]). However, the interventions for PAD in a real-world clinical setting are often simultaneously performed for several different locations. Methods: We conducted a prospective multicenter study that included 2,230 patients with PAD who received intervention for lower extremity lesions in each area and across different areas. Patients were divided into 7 groups according to the combination of treatment locations. Overall survival (OS), major adverse limb events (MALEs), and risk factors for OS and MALEs were statistically analyzed. Results: After adjustment for confounding factors, the attributable risk for OS was similar among isolated AI, FP, and BTK treatments. MALEs increased in correlation with the number of treatment locations. Dialysis and critical limb ischemia were the common risk factors for OS and MALEs. However, the contribution of other factors such as type of drug usage was different according to treatment locations. Conclusions: In patients with PAD, OS was largely defined by comorbidities but not by lesion location. The background risk factors, underlying comorbidities, and event rates were different according to PAD location, suggesting that stratified treatment should be established for different patient populations.

Abstract
OBJECTIVE Aggressive endovascular interventions for patients without adequate full-length venous conduit have gained popularity. The purpose of this study is to evaluate the outcomes of spliced vein bypass (SVB) as primary treatment versus treatment after failed endovascular intervention (endovascular SVB [ESVB]) for infrainguinal revascularization. METHODS A retrospective analysis of a single vascular group's database of all SVBs was queried for demographics, indications, intraoperative details, and outcomes. Exclusion criteria included acute ischemia, aneurysm, dual outflow, bypass revisions, and patients lost to immediate follow-up. SPSS software was used for statistical analysis. RESULTS Two hundred thirty-five infrainguinal SVBs were performed between January 2011 and March 2017. There were 182 SVB (77%) and 53 ESVB (23%) with a mean follow-up of 488 days (range, 1-2140). Demographics between the SVB and ESVB groups were similar in all categories recorded: diabetes, hypertension, coronary artery disease, current smoker, chronic obstructive pulmonary disease, hyperlipidemia, and renal disease (P = .29). Indications for bypass were not statistically significant between SVB and ESVB (P = .48). The study included Rutherford class 3 (14 vs 2), class 4 (51 vs 20), class 5 (67 vs 18), and class 6 (50 vs 13). Inflow was grouped into iliac (2.6%), femoral (88%), and popliteal (9.8%). Outflow arteries were grouped into below knee popliteal (14.9%) and infrapopliteal (85.1%). Inflow and outflow arteries, as well as number of spliced pieces per bypass were not different between groups. Major amputation rates were not different between SVB and ESVB for the entire study period. There was no statistical difference with patency outcomes based on Kaplan-Meier survival analysis (P = .84). CONCLUSIONS An aggressive endovascular first strategy for treatment of patients without adequate autogenous conduit seems to offer benefit without negatively affecting future bypass options. SVB patency and major amputation rates in this series were not affected by a prior endovascular treatment.

Abstract
GUIDELINE SUMMARY Chronic limb-threatening ischemia (CLTI) is associated with mortality, amputation, and impaired quality of life. These Global Vascular Guidelines (GVG) are focused on definition, evaluation, and management of CLTI with the goals of improving evidence-based care and highlighting critical research needs. The term CLTI is preferred over critical limb ischemia, as the latter implies threshold values of impaired perfusion rather than a continuum. CLTI is a clinical syndrome defined by the presence of peripheral artery disease (PAD) in combination with rest pain, gangrene, or a lower limb ulceration >2 weeks duration. Venous, traumatic, embolic, and nonatherosclerotic etiologies are excluded. All patients with suspected CLTI should be referred urgently to a vascular specialist. Accurately staging the severity of limb threat is fundamental, and the Society for Vascular Surgery Threatened Limb Classification system, based on grading of Wounds, Ischemia, and foot Infection (WIfI) is endorsed. Objective hemodynamic testing, including toe pressures as the preferred measure, is required to assess CLTI. Evidence-based revascularization (EBR) hinges on three independent axes: Patient risk, Limb severity, and ANatomic complexity (PLAN). Average-risk and high-risk patients are defined by estimated procedural and 2-year all-cause mortality. The GVG proposes a new Global Anatomic Staging System (GLASS), which involves defining a preferred target artery path (TAP) and then estimating limb-based patency (LBP), resulting in three stages of complexity for intervention. The optimal revascularization strategy is also influenced by the availability of autogenous vein for open bypass surgery. Recommendations for EBR are based on best available data, pending level 1 evidence from ongoing trials. Vein bypass may be preferred for average-risk patients with advanced limb threat and high complexity disease, while those with less complex anatomy, intermediate severity limb threat, or high patient risk may be favored for endovascular intervention. All patients with CLTI should be afforded best medical therapy including the use of antithrombotic, lipid-lowering, antihypertensive, and glycemic control agents, as well as counseling on smoking cessation, diet, exercise, and preventive foot care. Following EBR, long-term limb surveillance is advised. The effectiveness of nonrevascularization therapies (eg, spinal stimulation, pneumatic compression, prostanoids, and hyperbaric oxygen) has not been established. Regenerative medicine approaches (eg, cell, gene therapies) for CLTI should be restricted to rigorously conducted randomizsed clinical trials. The GVG promotes standardization of study designs and end points for clinical trials in CLTI. The importance of multidisciplinary teams and centers of excellence for amputation prevention is stressed as a key health system initiative.

Abstract
Atherosclerotic disease is currently one of the most important problems of modern medicine because it is a leading cause of increased morbidity, morbidity and mortality, and disability in the Western World. Atherosclerosis of the lower limbs (peripheral arterial disease - PAD) significantly affects the quality of life and in a considerable proportion of patients is a cause of disability. Radical treatment of PAD, both surgical and endovascular, aims at revascularisation of ischaemic tissues distal to obstructed arteries. Surveillance imaging is an important part of patient management after endovascular repair of PAD. Apart from availability and contraindications, challenges of imaging include calcifications, flow dynamics, and stent-related artefacts. The aim of this paper was to review the current literature on imaging methods for follow-up after endovascular repair of atherosclerotic lesions, with special attention paid to novel techniques. As a non-invasive modality, ultrasound is still the first-line examination, but computed tomography angiography remains a current state-of-the art technique for follow-up. However, since current imaging recommendations seem not to adhere to contemporary imaging possibilities, more attention should be paid to recent improvements in magnetic resonance angiography technology.

Abstract
The optimal approach for repeat revascularization after failed endovascular intervention for critical limb ischemia (CLI) is unclear. This study compared major adverse limb events (MALEs) and major adverse cardiac events (MACEs) between lower extremity bypass (LEB) and repeat endovascular intervention (REI) in patients with prior failed ipsilateral endovascular intervention. American College of Surgeons National Surgical Quality Improvement Program database identified patients undergoing LEB and endovascular intervention for CLI from 2011 to 2014. We compared REI to LEB with single-segment saphenous vein (LEB-SV) and LEB alternative conduit (LEB-alt). Primary outcomes were 30-day MALE and MACE. Multivariate analysis identified independent predictors of MALE and MACE. A total of 1567 revascularizations were performed after failed ipsilateral endovascular intervention (REI: 683 [43.5%], LEB-SV: 570 [36.4%], LEB-alt: 314 [20.0%]). There were 994 and 573 suprageniculate and infrageniculate revascularizations, respectively. Major adverse cardiac events were significantly lower after REI compared to LEB (REI: 15 [2.2%], LEB-SV: 33 [5.8%], LEB-alt: 21 [6.7%], P < .001). Major adverse limb event were not different between groups ( P = .99). In patients with CLI presenting after failed endovascular intervention, REI is associated with lower MACE without an increased risk of MALE compared to LEB. When the anatomy is amenable, REI should be considered a less morbid first option.

Abstract
BACKGROUND Endovascular surgery has become the initial treatment for most patients with chronic ischemia of the lower limbs. Few studies support ultrasound surveillance (US) of this kind of procedures. The purpose of this study was to evaluate the initial efficacy of duplex ultrasound as a surveillance method in endovascular treatment in symptomatic peripheral arterial disease patients in our center. MATERIAL AND METHODS A total of 113 endovascular procedures performed in 106 patients between February 2013 and June 2015 were included. Follow-up included clinical assessment, physical examination, ankle-brachial index (ABI), plethysmography, and ultrasound at 1, 3, 6, 12, 18, and 24 months after surgery. Patients without a minimum follow-up of two controls were excluded. Worsening was defined as follows: (1) in ultrasound, a restenosis >70%; (2) from ABI, a decrease >0.15; (3) clinically, a decrease in claudication distance, reappearance rest pain, or worsening injuries; (4) in plethysmography, flattening in the curve. RESULTS The average age was 68.3 years, with 72% being men. Twenty-two percent of treated lesions were iliac, 57% were femoropopliteal, and 21% were distal. There were 329 visits, with a mean follow-up of 13.5 months (3-31). The US detected permeability or moderate stenosis in 66 patients (58.4%) and restenosis or occlusion in 47 (41.6%). When compared with clinical status, there was a noncorrelation in 23% and a discrepancy with respect to the ABI of 27% and of 39% with plethysmography. All these differences were statistically significant (P < 0.001). Twenty-one reinterventions were performed (18.6%), six patients died (5.3%), and 11 required major amputation (9.7%). CONCLUSIONS Clinical status and hemodynamics can detect restenosis or occlusion of the procedure in a large part of the cases, but it can omit more than 20% of these that were only detected by US. The ultrasound follow-up is of great help to increase the reliability of the control in patients with endovascular revascularization of lower limbs.

Abstract
Objective Patients with critical limb ischemia have serious systemic comorbidities and are at high risk of impairment of limb function. In this study, we assessed the prognostic factors of limbs after revascularization. Methods In this retrospective single-center cohort study, from April 2008 to December 2012, we treated 154 limbs of 121 patients with critical limb ischemia by the endovascular therapy-first approach based on the patients’ characteristics. The primary end point was amputation-free survival. Secondary end points were patency of a revascularized artery, major adverse limb events, or death. Furthermore, we investigated the ambulatory status one year after revascularization as prognosis of limb function. Results Endovascular therapy was performed in 85 limbs in 65 patients as the initial therapy (endovascular therapy group) and surgical reconstructive procedures (bypass group) were performed in 69 limbs in 56 patients. Early mortality within 30 days was not observed in either group. The primary patency rate was significantly better in the bypass group than in the endovascular therapy group ( p < 0.0001). Furthermore, the secondary patency rate was similar between the two groups ( p = 0.0096). There were no significant differences in amputation-free survival and major adverse limb event between the two groups. Univariate analysis showed that ulcer healing ( p < 0.0001), no hypoalbuminemia ( p = 0.0019), restoration of direct flow below the ankle ( p = 0.0219), no previous cerebrovascular disease ( p = 0.0389), and Rutherford 4 ( p = 0.0469) were predictive factors for preservation of ambulatory status one year after revascularization. In multivariate analysis, ulcer healing ( p < 0.0001) and restoration of direct flow below the ankle ( p = 0.0060) were significant predictors. Conclusions Ulcer healing and restoration of direct flow below the ankle are independently associated with prognosis of limb functions in patients who undergo infrainguinal arterial reconstruction.

Abstract
OBJECTIVE There are conflicting reports about outcomes after infrainguinal bypass for chronic limb-threatening ischemia (CLTI) in patients with diabetes. We compared perioperative outcomes between patients with and patients without diabetes in the current era. METHODS The National Surgical Quality Improvement Program vascular module, 2011 to 2014, was used to identify patients undergoing infrainguinal revascularization for CLTI. Patients with and without diabetes were compared in terms of presentation, comorbidities, operative approach, and 30-day outcomes. Major adverse limb events (MALEs) included 30-day major reintervention or amputation, and major adverse cardiovascular events (MACEs) included 30-day myocardial infarction, cardiac arrest, stroke, or death. Multivariable logistic regression was used to adjust for baseline differences. RESULTS We identified 8887 patients undergoing open (5744; 50% diabetic) or endovascular (3143; 62% diabetic) treatment for CLTI. Patients with diabetes were younger and more often nonwhite, nonsmokers, and obese. Patients with diabetes presented more often with tissue loss (71% vs 47%; P < .001) and were more likely to be treated with endovascular intervention (41% vs 29%; P < .001). The 30-day mortality was similar before (open, 3.1% vs 2.8% [P = .53]; endovascular, 2.6% vs 2.1% [P = .37]) and after adjustment for baseline differences (open: odds ratio [OR], 1.1 [95% confidence interval (CI), 0.7-1.5]; endovascular: OR, 1.2 [95% CI, 0.7-2.0]). Patients with diabetes had longer lengths of stay (open, 8 vs 6 days [P < .001]; endovascular, 3 vs 2 days [P < .001]) and higher 30-day readmission rates (open, 21% vs 18% [P < .01]; endovascular, 20% vs 15% [P < .01]); however, these differences were no longer significant after adjustment for baseline differences. Patients with diabetes had a higher rate of MACEs (7.0% vs 5.1%; P < .01) and lower rate of MALEs (8.1% vs 10%; P < .01) after bypass. After adjustment, patients with diabetes still had a lower rate of MALEs (OR, 0.7; 95% CI, 0.6-0.9) but no longer had a higher rate of MACEs (OR, 1.2; 95% CI, 0.9-1.6). CONCLUSIONS CLTI patients with diabetes undergoing revascularization have similar 30-day outcomes compared with those without diabetes, although they appear to be at lower risk for MALEs after bypass. Prolonged length of stay and readmission in patients with diabetes is not due to underlying diabetic disease but likely secondary to other baseline comorbidities, such as higher rates of tissue loss. Concern for worse perioperative outcomes in patients with diabetes after lower extremity bypass is unsubstantiated and should not discourage a physician from performing an open bypass.

Abstract
BACKGROUND Endovascular treatment of infrapopliteal peripheral arterial disease (PAD) is an established and effective treatment strategy for patients with symptomatic PAD. Increasingly, complex infrapopliteal lesions are treated with an endovascular first approach, especially in the setting of critical limb ischemia (CLI) for limb salvage, avoiding major amputations which impact on mobility and quality of life. However, many complex infrapopliteal lesions involving the bifurcation of the tibial arteries remain challenging to treat because of recoil or acute dissection after angioplasty and may require stenting using specialized techniques. METHODS AND RESULTS We illustrated techniques for infrapopliteal arterial bifurcation stenting using case-based examples. The techniques covered include the single-stent, culottes, kissing, crush, and T-stenting techniques, and each is considered based on individual strengths and limitations. CONCLUSIONS Infrapopliteal bifurcation stenting allows complex bifurcation lesions to be treated effectively when flow-limiting complications are encountered after angioplasty.

Abstract
PURPOSE We aimed to evaluate limb salvage, defined as freedom from major amputation, and to identify predictors of major amputation in patients with infrapopliteal peripheral arterial disease (PAD) based on the updated 2015 TASC II anatomic classification treated by percutaneous transluminal angioplasty (PTA). METHODS This was a retrospective study of infrapopliteal PTA procedures performed for PAD over a 4-year period. Patient demographics, medical comorbidities, risk factors, angiographic imaging, technical details, and clinical follow-up were analyzed to determine limb salvage rates, technical success, and all-cause mortality. Predictors of major amputation following PTA were identified. RESULTS A total of 112 patients were treated by infrapopliteal PTA. Most lesions consisted of TASC C (44%) and D (34%) categories, were over 10 cm in length, and were occlusive and heavily calcified (89%). Overall technical success was 75%, with limb salvage rates of 77% at 1 year and 65% at 3 years following PTA. Smoking, previous stroke or cardiovascular events, and anticoagulation use were associated with an increased risk of major amputation following PTA. CONCLUSION PTA of complex infrapopliteal PAD is associated with good intermediate term limb salvage rates.

Abstract
Critical limb ischemia (CLI) is the most severe form of peripheral arterial disease (PAD) that may result in limb loss and even death; thus, the fast and proper treatment should be employed as earlier as possible to prevent these catastrophic consequences. Arterial revascularization is almost always an indispensable treatment option for CLI. Although both endovascular and surgical revascularization procedures have an important role, nowadays, the hybrid revascularization as a combination of these revascularization procedures has also gained increasing popularity in the treatment of patients with CLI. This review provides an update on the arterial revascularization strategies for the treatment of CLI.

Abstract
Introduction Progressive improvement in the ability to treat complete total occlusions in the tibial level arterial circulation have made it possible to revascularize patients with critical limb ischemia. Report A 59 year old male presented with a complete total occlusion of his anterior tibial artery with distal reconstitution through peroneal artery collaterals. During attempted angioplasty a balloon was retained within the patent portion of the target vessel. Two 3.0 mm drug eluting coronary stents were deployed across the length of the balloon with excellent luminal preservation. Discussion Successful CTO revascularization was completed and a strong dorsalis pedis artery pulse was restored following intervention. Improved treatment for tibial level arterial occlusions makes revascularization possible. A balloon was retained in the target vessel and two coronary stents were deployed across the balloon. CTO revascularization was successful with restoration of a strong dorsalis pedis pulse.

Abstract
Purpose: To describe the dual bull’s-eye technique to achieve successful extravascular revascularization of an occlusion after vessel perforation when the antegrade and retrograde catheters are too far apart for salvage with a reentry catheter. Technique: The dual bull’s-eye technique, which is an adaptation of the “gun-sight” method for transjugular portosystemic shunt procedures, is demonstrated in a popliteal artery occlusion in which multiple recanalization attempts have produced vessel perforation. Via antegrade femoral and retrograde anterior tibial artery accesses, 10-mm Amplatz GooseNeck snares were advanced in plane from each access to rendezvous in the popliteal fossa to obtain through-and-through wire access. A 15-cm Chiba needle was advanced percutaneously in plane through both snares, and a hydrophilic guidewire was maneuvered across an extravascular tract parallel to the popliteal artery. The tract was carefully predilated, and a 5×100-mm Viabahn stent-graft was deployed across the extravascular tract. Conclusion: Owing to potential complications (limited patency, injury to adjacent structures) and only single-case use, this new technique should be considered a bailout strategy exclusively employed for limb salvage when traditional methods have failed and there are no viable surgical options.

Abstract
OBJECTIVE The effects of concomitant endovascular interventions on multiple infrapopliteal vessels are not well known, and the short-term and long-term sequelae of such procedures have not been reported. METHODS From 2004 to 2014, 673 limbs in 528 patients underwent an infrapopliteal endovascular intervention for tissue loss (77%), rest pain (13%), stenosis of a previously treated vessel (5%), acute limb ischemia (3%), or claudication (2%). Outcomes included wound healing, RAS events (reintervention, major amputation, or stenosis [>3.5x step-up by duplex]), and mortality. Patients without an initial indication of critical limb ischemia (CLI) were excluded. Patients were characterized as having undergone either a single-vessel infrapopliteal intervention or a multiple-vessel infrapopliteal intervention. RESULTS Of the 673 limbs, 558 underwent a successful infrapopliteal endovascular intervention for CLI (86% for tissue loss, 14% for rest pain). During a single procedure, 503 limbs (90%) underwent a single-vessel intervention and 55 (10%) underwent a multiple-vessel intervention. Patients undergoing a single-vessel intervention more commonly underwent a prior ipsilateral endovascular procedure (17% vs 6%; P = .03) or a prior ipsilateral bypass procedure (20% vs 9%; P = .04). Kaplan-Meier analysis revealed that a RAS event ≤1 year occurred in 229 limbs (49%), with no significant difference in the 1-year rates of reintervention (22% vs 20%; P = .53), major amputation (16% vs 10%; P = .24), or stenosis (29% vs 21%; P = .25). After adjustment for baseline characteristics, multivariable regression illustrated that neither major amputation rates nor RAS events differed between patients undergoing a single-vessel vs a multiple-vessel intervention (P = .26 and P = .61, respectively). CONCLUSIONS Our data suggest that a multiple-vessel intervention does not improve outcomes when compared to a single-vessel intervention following infrapopliteal angioplasty for CLI.

Abstract
PURPOSE To assess the influence of repeat intervention on the risk of major amputation after infrapopliteal angioplasty for patients with critical limb ischemia (CLI). METHODS A multicenter database of Japanese CLI patients was interrogated to identify patients who underwent balloon angioplasty for isolated infrapopliteal lesions from April 2004 to December 2012. In that time frame, 1298 limbs of 1065 patients (mean age 72±10 years; 739 men) were eligible for this analysis. The prevalence of tissue loss was 76%, with 33% accompanied by infection. The association between repeat intervention and future risk for major amputation was evaluated using a mixed effects logistic regression model. A stratification analysis was also performed with baseline variables. A supplementary analysis compared baseline characteristics between the cases with and without repeat intervention. Hazard ratios (HR) and their 95% confidence intervals (CI) are reported. RESULTS Median follow-up was 1.2 years (interquartile range 0.4-2.5), during which time 143 (11.0%) limbs had major amputations and 499 (38.4%) underwent repeat intervention. The mixed effects modeling revealed that repeat intervention was significantly associated with future risk for major amputation (unadjusted HR 3.01, 95% CI 2.05 to 4.41, p=0.001). From the stratification analysis, repeat intervention significantly increased future risk of major amputation in cases with regular dialysis (HR 3.35, 95% CI 2.14 to 5.26, p<0.001), whereas it did not in those without dialysis. The supplemental analysis showed that patients with repeat intervention within 1 year had a higher prevalence of nonambulatory status, regular dialysis, tissue loss, and infection at baseline compared to those without repeat intervention for 1 year. CONCLUSION In the patients with CLI due to infrapopliteal lesions, the need for repeat intervention increased the risk of future major amputation. However, this correlation was not applicable to nondialysis patients.

Gonzalez AA, Cruz CG, Dev S, Osborne NH. Indication for Lower Extremity Revascularization and Hospital Profiling of Readmissions. Ann Vasc Surg 2016; 35:130-7. [PMID: 27311949 DOI: 10.1016/j.avsg.2016.01.054] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2015] [Revised: 01/19/2016] [Accepted: 01/22/2016] [Indexed: 11/19/2022]
Abstract
BACKGROUND Surgical readmissions are common, costly, and the focus of national quality improvement efforts. Given the relatively high readmission rates among vascular patients, pay-for-performance initiatives such as Medicare's Hospital Readmissions Reduction Program (HRRP) have targeted vascular surgery for increased scrutiny in the near future. Yet, the extent to which institutional case mix influences hospital profiling remains unexplored. We sought to evaluate whether higher readmission rates in vascular surgery are a reflection of worse performance or of treating sicker patients. METHODS This retrospective observational cohort study of the national Medicare population includes 479,047 beneficiaries undergoing lower extremity revascularization (LER) in 1,701 hospitals from 2005 to 2009. We employed hierarchical logistic regression to mimic Center for Medicare and Medicaid Services methodology accounting for age, gender, preexisting comorbidities, and differences in hospital operative volume. We estimated 30-day risk-standardized readmission rates (RSRR) for each hospital when including (1) all LER patients; (2) claudicants; or (3) high-risk patients (rest pain, ulceration, or tissue loss). We stratified hospitals into quintiles based on overall RSRR for all LERs and examined differences in RSRR for claudicants and high-risk patients between and within quintiles. Next, we evaluated differences in case mix (the proportion of claudicants and high-risk patients treated) across quintiles. Finally, we simulated differences in the receipt of penalties before and after adjusting for hospital case mix. RESULTS Readmission rates varied widely by indication: 7.3% (claudicants) vs. 19.5% (high risk). Even after adjusting for patient demographics, length of stay, and discharge destination, high-risk patients were significantly more likely to be readmitted (odds ratio 1.76, 95% confidence interval 1.71-1.81). The Best hospitals (top quintile) under the HRRP treated a much lower proportion of high-risk patients compared with the Worst hospitals (bottom quintile) (20% vs. 56%, P < 0.001). In the absence of case-mix adjustment, we observed a stepwise increase in the proportion of hospitals penalized as the proportion of high-risk patients treated increased (35-60%, P < 0.001). However, after case-mix adjustment, there were no differences between quintiles in the proportion of hospitalized penalized (50-46%, P = 0.30). CONCLUSION Our findings suggest that the differences in readmission rates following LER are largely driven by hospital case mix rather than true differences in quality.

Abstract
BACKGROUND Multidetector computed tomography angiography (MDCTA) and magnetic resonance angiography (MRA) are accurate techniques for selecting patients with peripheral arterial disease for surgical and endovascular treatment. No studies in the literature have directly compared MDCTA and MRA to establish which one should be employed, in patients suitable for both techniques, before endovascular treatment. PURPOSE To compare diagnostic performance of MDCTA vs MRA before endovascular intervention. MATERIAL AND METHODS We prospectively compared MDCTA (64 slices scanner) and MRA (1.5 T scanner; 3D gadolinium-enhanced bolus-chase acquisition plus time resolved acquisition on calves) to stratify 35 patients according to the TASC II score and a runoff severity score. We also evaluated the accuracy of both techniques in each arterial segment. Selective angiography performed during the treatment was the standard of reference. RESULTS MDCTA and MRA accurately classify disease in the aorto-iliac (accuracy 0.92 for MDCTA and MRA) and femoro-popliteal (MDCTA 0.94, MRA 0.90) segments. MDCTA was more accurate in stratifying disease in the infrapopliteal segments (0.96 vs. 0.9) and in assessing the impairment of runoff arteries (0.92 vs. 0.85) at per-segment analysis. MDCTA showed a higher confidence and a shorter examination time. CONCLUSION Our results suggest that MDCTA can be considered as a first-line investigation in patients being candidates for endovascular procedures when clinical history or duplex sonographic evaluation are indicative of severe impairment of the infrapopliteal segment.

Abstract
AIM Infrapopliteal occlusive arterial lesions mostly characterize diabetic patients arteriopathy. Diabetic patients are prone to multiple comorbidities that make them candidates for low-invasive therapeutic options. The aim of this study was to evaluate the safety of infrapopliteal angioplasty in high-risk diabetic patients. METHODS We undertook a study (retrospective study of a prospectively collected database) of all infrapopliteal endovascular revascularizations performed for critical limb ischemia in high-risk (≥3 major comorbidities) diabetic patients in our institution between 2008 and 2010. Study end points were safety, technical success rate, healing rate, overall 1-year survival, primary patency, secondary patency and limb salvage rates. RESULTS A total of 101 high-risk diabetic patients (160 arterial lesions: 94 stenosis and 66 occlusions) underwent infrapopliteal endovascular surgery. No major adverse cardiovascular or cerebrovascular event was recorded within 30 days. Two major adverse limb events (two thromboses requiring major amputation) and seven minor adverse events were recorded. Technical and healing rates were, respectively, 83% and 78%. The 1-year survival, primary patency, secondary patency and limb salvage rates were, respectively, 86%, 67%, 83% and 84%. CONCLUSION Infrapopliteal angioplasty can be considered as a safe and feasible option for high-risk diabetic patients with critical limb ischemia.

Costs of Real-Life Endovascular Treatment of Critical Limb Ischemia: Report from Poland-A European Union Country with a Low-Budget Health Care System. Ann Vasc Surg 2015; 31:111-23. [PMID: 26616505 DOI: 10.1016/j.avsg.2015.08.016] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2015] [Revised: 07/28/2015] [Accepted: 08/05/2015] [Indexed: 11/22/2022]
Abstract
BACKGROUND To analyze the costs of inhospital, percutaneous treatment of patients with critical limb ischemia (CLI) carried out in Poland, a European Union country with a low-budget national health system. METHODS A retrospective analysis of prospectively collected data on all patients admitted to a tertiary care hospital for endovascular treatment of CLI over 1 year. SETTING A single, large volume, tertiary angiology center located in Southern Poland. PARTICIPANTS CLI patients due to aortoiliac, femoropopliteal, or infrapopliteal arterial stenoses or occlusions with indications for first-line endovascular therapy or similar patients who refused open surgical procedure despite having primary indications for vascular surgery. INTERVENTIONS Direct stenting using bare-metal stents was the primary mode of treatment for lesions located within the aortoiliac and femoropopliteal arterial segments. Plain old balloon angioplasty (POBA) was the second most commonly used technique. For below-the-knee arteries, POBA was the mainstay of treatment, which was occasionally supported by drug-eluting stent angioplasty. Directional atherectomy, scoring balloon angioplasty, or local fibrinolysis was used infrequently. Drug-eluting balloon percutaneous transluminal angioplasty was not used. MAIN OUTCOME MEASURES The main outcome measures were the mean reimbursement of costs provided by the Polish National Health Fund (NHF) for inhospital treatment of patients for whom endovascular procedures were performed as initial treatment for CLI and the inhospital costs of endovascular treatment calculated by the caregiver in the 2 years since the first procedure. The average total number of days spent in hospital, amputation-free survival (AFS), overall survival (OS), and limb salvage rate (LSR) according to a life-table method were also calculated for the 2 years. RESULTS In the first year, there were 496 endovascular and 15 surgical hospitalizations for revascularization procedures to treat 340 limbs in 327 patients, with a further 53 revascularization procedures in the second year. There were an additional 90 hospitalizations over the first year and 38 over the second year for CLI-associated cardiovascular comorbidities. The mean reimbursement for hospitalizations of patients included into observation, provided by the NHF, was $4901.94 per patient for the first year and $833.57 per patient alive to the second year. The mean cost of hospitalization for percutaneous revascularization treatment was $3804.25 per patient for the first year and $3340.30 per patient requiring revascularization within the second year. All costs were calculated in constant 2011 USD. The average total number of days spent in hospital was 8.4 days for the first year and 1.97 days per patient alive to the second year. At 1 and 2 years, the AFS was 76.8% and 66.6%, the OS was 86.5% and 77.3%, and the LSR was 89.4% and 86%, respectively. CONCLUSIONS Endovascular therapy using the currently available techniques can be performed in almost all patients suffering from CLI at relatively low costs, and satisfactory results can be obtained. Physicians play a pivotal role in ensuring quality of treatment and the reduction of treatment cost in these patients.

Abstract
Acute limb ischemia (ALI) is one of the most common vascular emergencies, with high risk for limb loss if it is not treated expediently. Endovascular therapy is less invasive and used increasingly because of patient factors that disfavor open surgery despite limited quality data to support its safety and efficacy. This evidence summary reviews literature from 1990 to 2014, comparing contemporary surgical and endovascular revascularization. Systematic review was performed with emphasis on acuity of presentation, study design, revascularization techniques, limb salvage and mortality rates, and complications. There were 2999 articles identified and 563 abstracts reviewed; 68 articles were reviewed fully and 26 critically appraised. Limb salvage, amputation-free survival, overall survival and mortality, and treatment complications were elucidated, including Medicare outcomes data. Risk factors for amputation and mortality were identified. Surgical or endovascular revascularization for ALI is achievable with acceptable limb salvage and amputation rates, which are not markedly different between the two modalities in the short term. Endovascular therapy and surgery are complementary rather than competing strategies for ALI. Further good-quality clinical trial data are needed to define longer term outcomes.

Abstract
Background and Aim: To evaluate the amputation-free survival after below the knee percutaneous transluminal angioplasty in a consecutive group of patients with critical ischemia of the lower extremity. Materials and Methods: A total of 70 consecutive patients with critical ischemia were treated with below the knee percutaneous transluminal angioplasty at the vascular center at Rigshospitalet with the purpose of limb salvage. All patients were deemed unfit for major surgery due to anatomical limitations or severe co-morbidity, and no prior attempts of revascularization were performed. Follow-up clinical examinations were performed within 6 weeks and after 1 year. All medical records were crosschecked with the national vascular registry ensuring a valid 1-year status in 97% of the patients. Results: A total of 15 major amputations were performed during follow-up, with 11 amputations performed within the first year. Complications after percutaneous transluminal angioplasty were rare. Cumulative mortality after 1 and 2 years was 22% and 34%, respectively. Amputation-free survival at 1 and 2 years of follow-up was 68% and 58%, respectively. There were no association between known risk factors such as diabetes, ischemic ulcers, cardiac disease, history of smoking, major amputation, or overall amputation. Conclusion: Below the knee percutaneous transluminal angioplasty in patients with end-stage peripheral arterial disease and critical limb ischemia is a safe procedure in relieving critical ischemia, reducing the short-term rate of a major amputation as opposed to best medical treatment alone.
