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.

Abstract
PURPOSE Endovascular revascularization is the preferred treatment to improve perfusion of the lower extremity in patients with chronic limb-threatening ischemia (CLTI). Patients with CLTI often present with stenotic-occlusive lesions involving the infrapopliteal arteries. Although the frequency of treating infrapopliteal lesions is increasing, the reintervention rates remain high. This study aimed to determine the outcomes and patency of infrapopliteal endovascular reinterventions. METHODS This retrospective, multicenter cohort study of 3 Dutch hospitals included patients who underwent an endovascular infrapopliteal reintervention in 2015 up to 2021 after a primary infrapopliteal intervention for CLTI. The outcome measures after the reintervention procedures included technical success rate, the mortality rate and complication rate (any deviation from the normal postinterventional course) at 30 days, overall survival, amputation-free survival (AFS), freedom from major amputation, major adverse limb event (MALE), and recurrent reinterventions (a reintervention following the infrapopliteal reintervention). Cox proportional hazard models were used to determine risk factors for AFS and freedom from major amputation or recurrent reintervention. RESULTS Eighty-one patients with CLTI were included. A total of 87 limbs underwent an infrapopliteal reintervention in which 122 lesions were treated. Technical success was achieved in 99 lesions (81%). The 30-day mortality rate was 1%, and the complication rate was 13%. Overall survival and AFS at 1 year were 69% (95% confidence interval [CI], 55%-79%) and 54% (95% CI, 37%-67%), respectively, and those at 2.5 years were 45% (95% CI, 33%-56%) and 21% (95% CI, 11%-33%), respectively. Freedom from major amputation, MALE, and recurrent reinterventions at 1 year and 2.5 years were 59% (95% CI, 46%-70%) and 41% (95% CI, 25%-56%); 54% (95% CI, 41%-65%) and 36% (95% CI, 21%-51%); and 68% (95% CI, 55%-78%) and 51% (95% CI, 33%-66%), respectively. A Global Limb Anatomic Staging System score of III showed an increased hazard ratio of 2.559 (95% CI, 1.078-6.072; p=0.033) for freedom of major amputation or recurrent reintervention. CONCLUSIONS The results of this study indicate that endovascular infrapopliteal reinterventions can be performed with acceptable 30-day mortality and complication rates. However, outcomes and patency were moderate to poor, with low AFS, high rates of major amputations, and recurrent reinterventions. CLINICAL IMPACT This multicenter retrospective study evaluating outcome and patency of endovascular infrapopliteal reinterventions for CLTI, shows that endovascular infrapopliteal reinterventions can be performed with acceptable 30-day mortality and complication rates. However, the short- and mid-term outcomes of the infrapopliteal reinterventions were moderate to poor, with low rates of AFS and a high need for recurrent reinterventions. While the frequency of performing infrapopliteal reinterventions is increasing with additional growing complexity of the disease, alternative treatment options such as venous bypass grafting or deep venous arterialization may be considered and should be studied in randomized controlled trials.

Abstract
Patients with no-option chronic limb-threatening ischemia are not candidates for conventional revascularization options and will inevitably require major amputation. Deep venous arterialization (DVA) is a potential option for these patients. A complete endovascular system to perform DVA has recently received great acclaim and US Foor and Drug Administration approval. However, patients with severe tibial medial calcinosis such as those with diabetes or renal failure may not be candidates for this because most endovascular needles cannot penetrate severe calcium. Here we describe a novel hybrid approach to DVA that provided technical success in three patients with end-stage renal disease and severe medial calcinosis.

Abstract
BACKGROUND To establish the feasibility and safety of multimodal prehabilitation (MP), and to obtain pilot data on the change in quality of life, functional walking capacity, and the need for surgery for a full-scale trial. METHODS Pilot randomized controlled trial that included patients older than 50 years old suffering from moderate to severe intermittent claudication and who were candidates for endovascular revascularization (ER). Participants were excluded if they presented with ischemic rest pain, gangrene or ulceration of the index leg, significant lesions in the iliac vessels, planned surgical bypass, comorbidities in which exercise was contraindicated or if they were unable to speak English or French. Participants were randomized in a 1:1 ratio to 12 weeks of MP or institutional standard of care (unsupervised walking advice). MP consisted of i)1 weekly supervised exercise session; ii) home-based exercise prescription; iii) nutritional counseling and supplementation; iv) smoking cessation therapy; and v) psychosocial support. Feasibility and safety were measured with recruitment and retention rates, as well as the occurrence of any adverse events. In addition, barriers to attend supervised sessions and compliance to each component were assessed. Change in functional walking capacity, health-related quality of life, and the rates of patients deciding not to undergo ER were collected and analyzed throughout the follow-up period of 12 months. RESULTS Of the 37 patients referred for eligibility, 27 (73%) accepted to participate in the trial and were randomized. Of the 27 patients included, 24 completed the 12-week program. Adherence to each prehabilitation component was 83% interquartile range [72,93] for supervised exercise, 90% [83,96] for home-based exercise and 69% [45,93] for nutritional sessions. Fifty percent of patients were referred for and underwent psychosocial intervention and 40% of the active smokers enrolled in the smoking cessation program. No adverse events were observed during the program. The 2 main barriers for not fully adhering to the intervention were excessive pain while performing the exercises and the difficulty to keep up with the prescribed exercises. A statistically significant mean change (standard deviation (SD)) was seen in the MP group versus standard of care for functional capacity, mean (SD) 6 Min Walk Test 60 (74) vs. -11 (40) meters P < 0.05, and quality of life mean (SD) VascuQol 1.15 (0.54) vs. -0.3 (1.09) points P < 0.05. There was no statistically significant difference between groups in the rates of patients deciding to undergo ER during the 1-year follow-up period. CONCLUSIONS The results of this pilot trial demonstrate that MP is safe and feasible. A 12-week MP program seems to improve quality of life and functional walking capacity to a greater extent than unsupervised walking advice. There is a need for a large-scale trial to investigate the effectiveness of MP at improving quality of life and assessing its impact on the rates of patients deciding not to undergo or delay ER. The long-term functional and quality of life outcomes of the patients deciding to undergo ER after prehabilitation also need to be assessed.

Abstract
OBJECTIVES In this study, perioperative properties and early and mid-term clinical outcomes of endovascular revascularization with a combined usage of rotational atherectomy (RA) and drug-coated balloon angioplasty (DCB) angioplasty for isolated popliteal artery lesion were reported. METHODS A total of 28 patients with isolated popliteal artery stenosis who underwent combined RA and DCB angioplasty between December 2018 and September 2022 were analyzed retrospectively. Temren atherectomy system (Invamed, Ankara, Turkey) and Extender paclitaxel-coated drug-coated balloon catheter (Invamed, Ankara, Turkey) were used in all cases. The main outcome was primary patency; secondary outcomes were technical success, freedom from amputation, and mortality. RESULTS The mean age of patients was 64.2 ± 9.1 years and the majority of the patients were male (n = 20; 71.4%). Types of the lesions were total occlusion in 24 limbs and critical stenosis in 4 limbs. The mean total occlusion length was 65.2 ± 14.2 mm. Flow-limiting dissection was seen in lesions of 2 patients (7.1%) and treated with prolonged balloon dilatation without bail-out stenting requirement. Technical success defined as an adequate vascular lumen (less than 30% stenosis) was achieved in 26 (92.8%) with a mean follow-up of 17.2 ± 8.2 months. The mean primary patency rates at 12 months and 24 months were 92.3% ± 3.2 and 81.2% ± 3.2, respectively. Complications included 1 distal embolization following RA, 2 flow-limiting dissections, and 3 puncture site hematomas. CONCLUSIONS Endovascular procedures using combined RA and DCB angioplasty seem to be effective alternative treatment modalities for the treatment of popliteal artery lesions with high rates of primary patency and freedom from TLR.

Abstract
Critical limb-threatening ischemia is the most advanced stage of peripheral arterial disease, and patients with this problem represent a group at very high risk of limb loss. Until recently, patients with severe disease in the foot that was unreconstructable through the arterial system were relegated to treatment with wound care, pain management, and ultimately often faced major amputation. In recent investigations into the use of a percutaneous approach to venous arterialization, transcatheter arterialization of the deep veins has been evaluated as a mechanism to improve oxygen delivery to the foot in patients faced with the prospect of limb loss. Identifying patients who would benefit from this approach and a critical evaluation of the technique are provided along with expected outcomes. While the procedure remains in its infancy, early outcomes are promising, and continued advancement and improvement will further enhance options for these patients.

Abstract
Deep venous arterialization (DVA) is a final option for limb salvage in patients with end stage arterial anatomy. We report a 66-year-old dialysis dependent male with forefoot gangrene, Rutherford class 6 chronic limb ischemia, who required a redo endovascular DVA. On initial presentation an angiogram was demonstrated a desert foot with absent tibial runoff to his bilateral lower extremities. After discussion, patient elected to trial DVA in hope of avoiding a major amputation. A hybrid DVA was performed using a Pioneer Plus and .018″ Viabahn stents from the peroneal artery into the peroneal venous system; following this, the peroneal vein was anastomosed to the lesser saphenous vein via an open posterior approach at the ankle. 3 months later, a second DVA was performed by exposing the above knee popliteal artery and vein and creating an end-to-side anastomosis. Of note, the great saphenous vein was less than 2 mm in diameter and no arm vein was available due to history of prior fistulas in bilateral arms. Via the popliteal vein, the posterior tibial vein was selected and additional .018″ Viabahn stents were deployed from the malleolus to the P2 segment of the popliteal vein. Three months after the second hybrid DVA, the patient's forefoot had healed after split thickness skin grafting. Continued patency is noted of the re-do hybrid DVA with minimal calf edema. Newer creative strategies are required for "No Option Chronic Limb Ischemia" which is becoming more relevant in diabetic and dialysis dependent patients. This case illustrates the potential to convert a deep venous arterialization to a superficial venous arterialization for improved venous outflow and wound healing.

Abstract
BACKGROUND Peripheral artery disease (PAD) is a common disease associated with atherosclerosis, leading to significant mortality and morbidity worldwide. Our study focuses on the association between insulin resistance (IR) and PAD, specifically investigating the triglyceride-glucose index (TyG) as a potential surrogate marker of IR in the context of PAD by pooling the existing studies on this topic. METHODS Online databases, including PubMed, Embase, Scopus, and the Web of Science, were searched to find the studies comparing the TyG index in PAD vs. control, reporting the TyG index among PAD severities, and assessing the association of increase in TyG with PAD prevalence. Random-effect meta-analysis was performed to calculate the standardized mean difference (SMD) and 95% confidence interval (CI) for TyG level comparison and to calculate pooled odds ratio (ORs) for a 1-unit increase in TyG and higher vs. lower quartile/tertile of TyG association with PAD. RESULTS In the final review, 22 studies comprising 73,168 cases were included. Random-effect meta-analysis showed that patients with PAD had significantly higher levels of the TyG index compared with controls (SMD 0.76, 95%CI 0.65-0.88, P < 0.001). Also, higher severities of PAD were associated with higher TyG levels (SMD 0.48, 95%CI 0.22-0.74, P = 0.0003). Additionally, a 1-unit increase in TyG was associated with a 60% increase in odds of PAD (OR 1.60, 95%CI 1.41-1.80, P < 0.001). Finally, the highest quartile (Q4) of TyG had significantly higher odds of PAD compared to Q1 (OR 1.94, 95%CI 1.49-2.54, P < 0.001). CONCLUSION Our meta-analysis has identified a significant association between TyG levels and PAD and its severity. These findings not only contribute to our understanding of the role of IR in PAD pathology but also offer clinicians an exact index for evaluating PAD risk and its complications. This could potentially lead to more effective prevention and management strategies in the future.

Abstract
In drug-coated balloon (DCB) angioplasty for femoropopliteal lesions, there are adverse effects of drug embolization on downstream non-target organs following the slow-flow phenomenon. We devised a novel method, known as VaSodilator injection via the over-the-wire lumen during DCB dilatation to prevent the slow-flow phenomenon in treatment of femoropopliteal lesions (V.S.O.P.), and evaluated its efficacy and safety. This single-center, retrospective, observational study analyzed 196 femoropopliteal lesions treated with IN.PACT Admiral between April 2018 and July 2023. The IN.PACT Admiral is a DCB consisting of a 0.035-inch over-the-wire (OTW) lumen balloon coated with high-dose paclitaxel. Regarding the V.S.O.P. method, we injected vasodilators through the OTW lumen during DCB dilation of the lesions. The cohort was classified into two groups according to the use of the V.S.O.P. method (V.S.O.P. group: n = 53; non-V.S.O.P. group: n = 143). The V.S.O.P. group had lower rates of hemodialysis (21% vs. 43%, p = 0.01) and higher rates of critical limb-threatening ischemia (56% vs. 23%, p < 0.01) and severe calcification lesions (Peripheral Arterial Calcium Scoring Systems score 3/4) (53% vs. 34%, p = 0.01) than the non-V.S.O.P. group. The occurrence of the slow-flow phenomenon was significantly lower in the V.S.O.P. group than in the non-V.S.O.P. group. The V.S.O.P. method could be an effective method for preventing the slow-flow phenomenon after DCB angioplasty for femoropopliteal lesions.

J Vasc Surg 2024:S0741-5214(24)01881-0. [PMID: 39303863 DOI: 10.1016/j.jvs.2024.09.003] [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: 06/10/2024] [Revised: 08/27/2024] [Accepted: 09/09/2024] [Indexed: 09/22/2024]
Abstract
OBJECTIVE Poor glycemic control in the perioperative period has been reported to be associated with early and late major adverse limb events (MALE). However, these studies were mostly from large databases or lacked long-term outcomes. We examined the long-term effects of high hemoglobin A1c (HbA1c) level on patency, MALE, limb salvage (LS) and survival after lower extremity revascularization procedures in diabetic patients. METHODS Patients with diabetes who had revascularization for Rutherford class 3-6 ischemia between May 2002 and December 2018 were identified. Patients with HbA1c≤7% were compared to HbA1c>7% for patency, MALE, survival, LS and amputation-free survival (AFS). RESULTS Of 706 patients, 699 had HbA1c data (775 limbs), with 311 (357 limbs) in HbA1c≤7%, and 388 (418 limbs) in HbA1c>7% groups. Patients with HbA1c>7% were younger (69.9±10.2 vs 71.7±9.5, P=0.011), had higher lipid levels, insulin use (70% vs 49%, P<0.01), ASA 4, and had lower prevalence of chronic kidney disease (CKD) (32%vs41%, P=0.023). HbA1c>7% patients were more likely to present with chronic limb-threatening ischemia (CLTI) (79% vs 72%,P=0.019) and undergo infrapopliteal interventions (49% vs 42%, P=0.005), with no difference in anatomic complexity (TASC C/D, 75% vs 77%, p=0.72) or type of revascularization (24% vs 18% Open, 66% vs 70% EV, 10% vs 12% Hybrid, p=0.236). Patency and freedom from MALE were significantly lower in patients with HbA1c>7% for infra-inguinal revascularizations, whereas AFS and overall survival were similar. In patients with CLTI, LS rates at five years were significantly lower in patients undergoing open revascularization (HbA1c>7%: 64%±6%vs HbA1c<7%:86%±5%, P=0.020), whereas it was similar after endovascular interventions (HbA1c>7%:79%±4% vs HbA1c<7%:77%±3%, p=0.631). Seventy patients with HbA1c>7% lost limbs vs 38 patients with HbA1c≤7% (P=0.007). In multivariate analysis, HbA1c was significantly associated with primary patency. HbA1c, insulin use, level of intervention, and ACEI use were associated with MALE. CONCLUSIONS Perioperative HbA1c>7% is associated with poorer patency rates, and increased MALE especially at the infra-inguinal level revascularization in diabetics, with no significant impact on survival. Limb salvage is impacted after open, but not after endovascular revascularization.

Abstract
AIM The current study aimed to evaluate the effectiveness of peripheral blood mononuclear cells (PB-MNCs) therapy for patients with ischaemic diabetic foot ulcers (DFUs) treated through indirect revascularization. METHODS The study is a prospective non-controlled observational study including patients with neuro-ischaemic DFUs who received indirect peripheral revascularization and showed a persistence of wound ischaemia defined by the absence of angiographic collateral vessels and TcPO2 values < 30 mmHg in the wound angiosome area. All patients received 3 cycles of PB-MNCs therapy administered along the wound related artery based on the angiosome theory. The primary outcomes measures were healing, major amputation, and survival after 1 year of follow-up. The secondary outcomes measures were the evaluation of tissue perfusion by TcPO2 and foot pain defined by the Numerical Rating Scale (NRS). RESULTS Overall 52 (9.7%) patients were included. Most patients were aged (> 70 years), all of them were affected by Type 2 Diabetes with a long diabetes duration (> 20 years). Almost 80% were assessed as grade 2D- 3D of Texas University Classification. Forty-four patients (84.6%) patients healed and survived, 2 (3.85%) healed and deceased, 2 (3.85%) not healed and deceased, 4 (7.7%) not healed and survived. No major amputations were recorded. A significant increase of TcPO2 after PB-MNCs therapy were recorded in comparison to the baseline (43 ± 9 vs 18 ± 8 mmHg, p < 0.0001), such as a concomitant reduction of foot pain (1.8 ± 1.2 vs 6.2 ± 2.1, p < 0.0001). CONCLUSIONS PB-MNCs resulted effective to promote wound healing and limb salvage in diabetic patients with ischaemic DFUs who received indirect revascularization.

Abstract
BACKGROUND Although femoropopliteal-specific stents have durable patency, stent thrombosis (ST) may occur, which can lead to acute limb ischaemia (ALI). AIMS We aimed to investigate the clinical features and outcomes of ALI caused by femoropopliteal ST in patients with lower extremity artery disease. METHODS This multicentre retrospective study included 499 patients with ALI - of whom 108 patients had ALI caused by femoropopliteal ST (ST-ALI) and 391 patients had ALI caused by other aetiologies (de novo ALI) - who underwent treatment between September 2011 and March 2023. Clinical features and outcomes were compared between the two groups. The primary outcome measure was 12-month amputation-free survival; factors associated with amputation or death were investigated using multivariate Cox proportional hazards regression analysis. RESULTS Patients with ST-ALI were significantly more likely to exhibit conventional atherosclerotic risk factors, including diabetes mellitus (63% vs 26%) and haemodialysis (51% vs 10%) compared to patients with de novo ALI, whereas patients with de novo ALI were older (80 years vs 74 years) and more likely to have atrial fibrillation (49% vs 18%) than patients with ST-ALI. The 12-month amputation-free survival rate was significantly lower in the ST-ALI group than that in the de novo ALI group (51% vs 76%; p<0.001). Multivariate analysis revealed that ST-ALI, older age, haemodialysis, atrial fibrillation, the presence of a wound, peak C-reactive protein level, and non-ambulatory status all have an independent, positive association with death or major amputation. CONCLUSIONS The current study revealed that patients with ST-ALI had worse clinical outcomes than those with de novo ALI, highlighting the need to maximise ST prevention.

Abstract
INTRODUCTION Predicting the outcomes of endovascular revascularization of chronic limb-threatening ischemia (CLTI) patients with foot wounds can be challenging. Angiographic wound blush (WB) assessment has been found to be a helpful tool to assess wound perfusion. The aim of this study is to evaluate WB during endovascular revascularization of CLTI patients and its effects on treatment outcomes. METHODS This prospective study included all CLTI patients with foot wounds who underwent successful endovascular revascularization of infrainguinal arterial disease between 2019 and 2021. Patients were grouped according to the WB status into positive WB (group A) and negative WB (group B). Both groups were compared for demographics, comorbidities, clinical picture, and 12-month limb-based patency (LBP) and amputation-free survival (AFS) rates. RESULTS The study included 69 patients of Rutherford classes 5 (46.4%) and 6 (53.6%), with the main arterial lesion located at the femoropopliteal (58%) or infrapopliteal (42%) segments. Completion angiography showed positive WB in 38 (55.1%) patients and negative WB in 31 (44.9%) patients. Both groups were comparable regarding patient presentation, site of the main arterial lesion, and distribution of foot lesions in relation to the feeding artery. The overall 12-month LBP and AFS rates were 21.7% and 39.1%, respectively, with significantly better rates in group A than in group B (LBP, 31.6% vs 9.7%, p = 0.001 and AFS, 54.1% vs 22.2%, p = 0.006, respectively). Successful angiosome-based direct flow to the foot was achieved in 38 patients (55.1%), resulting in significantly better 12-month AFS rates than those with indirect revascularization (54.8% vs 26.3%, p = 0.036, respectively), despite the comparable 12-LBP rates between the direct and indirect revascularization groups (29% vs 15.8%, p = 0.133, respectively). Multivariate logistic regression analysis identified smoking as a significant predictor of a major amputation, whereas positive WB and successful direct revascularization were significant predictors of limb salvage. CONCLUSIONS WB can serve as a predictor for AFS and LBP during endovascular revascularization of CLTI patients with foot wounds. A positive WB may guide the decision to conclude an endovascular procedure, potentially avoiding unnecessary complicated maneuvers to recanalize more vessels. Conversely, a negative WB may suggest the need for further revascularization attempts to augment wound perfusion and healing.

Abstract
Conservative therapy is favored over revascularization for patients with peripheral arterial disease (PAD) and intermittent claudication (IC) owing to the better long-term results. The adjunctive use of intravascular ultrasound (IVUS) significantly improves endovascular therapy. However, data on IVUS and IC is scarce. Therefore, the aim of this investigation was to determine the safety and efficacy of IVUS in patients with IC and to evaluate discrepancies compared to angiography and potential consequences for treatment.This was a single-center prospective cohort study. Twenty patients with IC and femoropopliteal disease eligible for endovascular therapy were enrolled. Procedural data and discrepancies between IVUS and angiography were recorded.In total, 30 lesions were treated. IVUS-based measurements yielded substantially higher reference vessel diameters (RVD) and lesion lengths compared to DSA alone (RVD: 5.37 ± 0.71 mm vs. 4.74 ± 0.63 mm, p<.001, lesion length: 62.4 ± 41.4 mm vs. 42.18 ± 30.2 mm, p<.001). In 24 of 30 lesions (80%), a significant discrepancy in RVD (defined as difference >0.5 mm) and lesion length (defined as >20 mm) was determined between IVUS and standard DSA. Subsequently, IVUS assessment led to upsizing in 14 of 30 lesions (47%) and downsizing in 3 of 30 lesions (10%). On average, IVUS led to the selection of considerably larger balloons (5.25 ± 0.62 vs. 4.74 ± 0.63, p<.004) and device length (78.97 ± 44.19 mm vs. 42.18 ± 30.2, p<.001). Serious adverse events did not occur. Technical success was achieved in all cases.IVUS is safe and provides advantages regarding the evaluation of IC by depicting RVD and lesion length more reliably than standard DSA. More precise assessment of lesions resulted in the use of significantly larger devices. · The safety and efficacy of IVUS are confirmed for the distinct cohort of patients with IC.. · IVUS provides advantages for the evaluation of IC by depicting RVD and lesion length more reliably than standard DSA.. · More precise assessment of stenoses resulted in the selection of significantly larger devices, hence suggesting substantial clinical impact..

Abstract
Objective Lower limb peripheral arterial disease in the symptomatic stage has a significant effect on patients´ functional disability. Before an intervention, an imaging diagnostic examination is necessary to determine the extent of the disability. This study evaluates cost-effectiveness of duplex ultrasonography (DUS), digital subtraction angiography (DSA), computed tomography angiography (CTA) and magnetic resonance angiography (MRA) in the diagnostics of symptomatic patients with lower limb peripheral arterial disease indicated for endovascular or surgical intervention. Methods Discrete event simulation was used to capture lifetime costs and effects. Costs were calculated from the perspective of the health care payer, and the effects were calculated as quality-adjusted life year's (QALY's). The cost-effectiveness analysis was performed to pairwise compare CTA, MRA and DSA with DUS as the baseline diagnostic modality. A scenario analysis and probabilistic sensitivity analysis were carried out to evaluate the robustness of the results. Results In the basic case, the DUS diagnostic was the least expensive modality, at a cost of EUR 10,778, compared with EUR 10,804 for CTA, EUR 11,184 for MRA, and EUR 11,460 for DSA. The effects of DUS were estimated at 5.542 QALYs compared with 5.554 QALYs for both CTA and MRA, and 5.562 QALYs for DSA. The final incremental cost-effectiveness ratio (ICER) value of all evaluated modalities was below the cost-effectiveness threshold whereas CTA has the lowest ICER of EUR 2,167 per QALY. However, the results were associated with a large degree of uncertainty, because iterations were spread across all cost-effectiveness quadrants in the probabilistic sensitivity analysis. Conclusion For imaging diagnosis of symptomatic patients with lower limb peripheral arterial disease, CTA examination appears to be the most cost-effective strategy with the best ICER value. Baseline diagnostics of the DUS modality has the lowest costs, but also the lowest effects. DSA achieves the highest QALYs, but it is associated with the highest costs.

Abstract
BACKGROUND Intermittent Claudication (IC) is exercise pain seen in lower extremity arterial diseases. If it is left untreated, it may be the initial sign of a process leading to amputation. In the present study, the purpose was to compare the postoperative early and mid-term results of the patients who were treated with endovascular methods and those who underwent bypass graft surgery in the treatment due to IC complaints because of isolated Femoropopliteal Arterial Disease. METHOD Postoperative first-month, sixth-month, and 12th-month follow-up results, procedure requirements, and demographic characteristics of the 153 patients who underwent femoropopliteal bypass because of isolated Femoropopliteal Arterial Disease and 294 patients who underwent endovascular intervention in our hospital between January 2015 and May 2020 were compared in the study. RESULTS It was found in demographic characteristics that endovascular intervention was performed more frequently in smokers and graft bypass surgery was performed more frequently in hyperlipidemic patients, and the results were found to be statistically significant. High amputation rates were detected at statistically significant levels in diabetic and hypertriglycemic patients and 1-year primary patency rates were found to be higher in patients who underwent graft bypass surgery. No differences were detected between the two methods in terms of mortality. CONCLUSION Interventional treatment modalities must be considered for patients with isolated Femoropopliteal Arterial Disease whose symptoms persist despite exercise and the best medical treatment. We think that Bypass Graft Surgery has more positive results than endovascular interventions when short and medium-term amputation, repetitive intervention needs, and changes in quality of life are compared in patients who receive the same medical treatment.

[PMID: 38821476 DOI: 10.1016/j.avsg.2024.03.026] [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: 01/24/2024] [Revised: 03/12/2024] [Accepted: 03/21/2024] [Indexed: 06/02/2024]
Abstract
BACKGROUND Antiplatelets and statins therapies are associated with improved cardiovascular outcomes following major vascular intervention. Many vascular surgery institutions are reporting improved prescribing rates for aspirin (ASA), P2Y12 antagonists, and statins. Nevertheless, there remains limited publication describing rates and patient-perceived barriers for postoperative adherence. The purpose of this study is to investigate patient nonadherence to antiplatelet and statin therapies following major vascular intervention. METHODS A retrospective review of patients who underwent major vascular intervention at a single academic center was performed. The prescribing rates of ASA, P2Y12 antagonists, and statins were reviewed. Postoperative adherence, defined as consistent intake as prescribed, was evaluated at 1, 3, 6, 9, and 12 months using electronic documentation of both follow-up clinic appointments and phone call assessments, then corroborated with pharmacy fulfilment records. Patient-reported barriers to medication adherence were also examined. RESULTS A total of 101 subjects underwent major vascular intervention between January 2020 and July 2020, 98% of whom were discharged on at least 1 antiplatelet or statin agent. Approximately 90% of patients were discharged with ASA, 32% with a P2Y12 antagonist, and 96% with a statin. All patients who maintained adherence up to 6 months continued to report adherence at 9 and 12 months. Consistent adherence at 12 months was documented in 76% of patients on ASA, 81% on P2Y12 antagonism therapy, and 73% on statins. New adverse drug reactions represented the most common barrier to achieving adherence (37% [n = 20]). Preoperative therapy with ASA, P2Y12 antagonists, and statins were all independently predictive of postoperative adherence to the same regimen (P ≤ 0.001). The female gender was also associated with higher rates of adherence to postoperative P2Y12 antagonism therapy (P ≤ 0.05). CONCLUSIONS The current prescribing rates for antiplatelet and statin agents are promising, but postoperative nonadherence remains a multifaceted issue.

Abstract
BACKGROUND AND AIMS Diet has an essential role in primary and secondary cardiovascular prevention by modulating various cardiovascular risk factors. The need to have easily useable tools seems essential to facilitate the daily practice of clinicians in order to propose the most optimal management of their patients' diet. The aim of this study was to compare the diet assessed with a simple food frequency questionnaire (FFQ) between patients with symptomatic peripheral artery disease (PAD) and healthy subjects. MATERIALS AND RESULTS In this ancillary study (ELECTRO-PAD study), we included symptomatic PAD patients and healthy participants. All participants filled a FFQ previously validated called Cardiovascular-Dietary-Questionnaire 2 (CDQ-2). CDQ-2 allows the calculation of different scores: global food score, saturated fatty acids score (SFA), unsaturated fatty acids score (UFA), fruit and vegetable score. The higher the score, the better the diet. We compared the different scores between PAD patients and healthy participants. We included 37 PAD patients and 40 healthy subjects. Mean global score was significantly lower in PAD patients compared to the healthy participants (5.35 ± 7.65 vs 10.60 ± 5.81; p = 0.0011). Similarly, the sub-scores concerning unsaturated fatty acids and fruits-vegetables were significantly lower in PAD patients (p < 0.010). Only the sub-score concerning saturated fatty acids was not significantly different (p = 0.8803) between PAD patients and healthy participants. CONCLUSION CDQ-2 highlights that PAD patients have an unfavorable diet compared with healthy participants. CDQ-2 is a tool of interest to help the clinicians for dietary advice of PAD patients.

Ann Vasc Surg 2024; 106:426-437. [PMID: 38815915 DOI: 10.1016/j.avsg.2024.03.013] [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: 11/10/2023] [Revised: 02/20/2024] [Accepted: 03/07/2024] [Indexed: 06/01/2024]
Abstract
BACKGROUND Aortoiliac occlusive disease (AIOD) has traditionally been treated with aortobifemoral bypass (ABF). Unibody endograft (UBE) for AIOD, however, has been increasingly utilized in selected patients. We report outcomes of patients undergoing ABF or UBE for AIOD. METHODS Patients (2016-2021) undergoing elective ABF or UBE with a unibody device for AIOD were identified at an academic institution. Chi-square and Kaplan-Meier analysis were used to evaluate outcomes by group. RESULTS One hundred thirty-one patients undergoing UBE or ABF were screened, with 82 included. Twenty-one patients underwent UBE (25.6%) and 61 (74.4%) underwent ABF. UBE patients were older (63.8 vs. 58.2 years; P = 0.01), with a higher prevalence of diabetes (52.4 vs. 19.7%; P = 0.004). Significant differences were seen between UBE and ABF including a shorter surgery length (214 vs. 360 min; P = 0.0001), less blood loss (300 vs. 620 mls; P = 0.001), larger minimum aortic diameter (14.6 vs. 12.6; P = 0.0006), larger common iliac artery (9.5 vs. 7.9; P = 0.005) and lower postoperative ankle-brachial index (0.8 vs. 0.9; P = 0.04). There were no differences in TASC C/D iliac lesions in the UBE than ABF group (66.6% vs. 63.9%; P < 0.82) or Trans-Atlantic Inter-Society Consensus classification femoropopliteal lesions. Unadjusted analysis revealed no significant differences between UBE and ABF for 30-day mortality (0 vs. 1.6%; P = 1), stroke (0 vs. 3.3%; P = 1), or major adverse cardiac events (4.8 vs. 4.9%; P = 1). There were no significant differences in mid-term surgical outcomes over a mean follow-up period of 23.7 months between UBE and ABF groups; specifically endovascular (0 vs. 8.2%; P = 0.3) or open/hybrid reintervention (9.5 vs. 14.8%; P = 0.7) with similar limb occlusion (4.8 vs. 27.8; P = 0.12). Kaplan-Meier estimated primary, primary-assisted, and secondary patency at 36 months were similar with 94%, 100%, and 94% for UBE and 86%, 95%, and 86% for ABF, respectively. Estimated survival at 36 months was 95% for UBE and 97% for ABF (P = 0.8). CONCLUSIONS Equivalent outcomes were seen between AIOD treated with UBE or ABF in similar patient populations. Mid-term outcomes such as reintervention and patency are similar for UBE and ABF. We still recommend ABF over UBE as a primary modality of treatment in surgically fit patients with greater complexity aortoiliac lesions and with smaller arterial diameters, especially women.

Abstract
PURPOSE To compare arm-ergometry and treadmill supervised exercise training on cardiorespiratory fitness and walking distances in patients with peripheral artery disease (PAD). METHODS ARMEX was a single-center, single-blinded, parallel group, non-inferiority trial enrolling symptomatic patients with PAD. Patients were randomized (1:1 ratio) to a 12-wk arm-ergometry (AEx) or standard treadmill (TEx) supervised exercise training protocol. The powered primary end point was the change in peak oxygen uptake (VO 2 ) at 12 wk, measured on a treadmill cardiopulmonary exercise test (CPX). Secondary outcomes included changes in VO 2 at the first ventilatory threshold (VT-1), ventilatory efficiency (ratio of minute ventilation [VE] to carbon dioxide production [VCO 2 ], VE/VCO 2 ), walking distances by CPX and 6-min walking test (6MWT), and self-reported walking limitations. RESULTS Fifty-six patients (66 ± 8 yr; 88% male) were randomized (AEx, n = 28; TEx, n = 28). At 12 wk, VO 2peak change was not significantly different between groups (0.75 mL/kg/min; 95% CI, -0.94 to 2.44; P = .378), despite a significant increase only in AEx. VO 2 at VT-1 improved in both groups without between-group differences, and VE/VCO 2 slope improved more in AEx. The TEx attained greater improvements in walking distance by CPX (121.08 m; 95% CI, 24.49-217.66; P = .015) and 6MWT (25.08 m; 95% CI, 5.87-44.29; P = .012) and self-perceived walking distance. CONCLUSIONS Arm-ergometry was noninferior to standard treadmill training for VO 2peak , and treadmill training was associated with greater improvements in walking distance. Our data support the use of treadmill as a first-line choice in patients with PAD to enhance walking capacity, but arm-ergometry could be an option in selected patients.

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] [MESH Headings] [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
OBJECTIVE Recent randomized controlled trials have demonstrated a notable prevalence of immediate technical failures in percutaneous vascular interventions (PVIs) for complex arterial lesions associated with chronic limb-threatening ischemia. Current imaging modalities present inherent limitations in identifying these lesions, making it challenging to determine the most suitable candidates for PVI. We present a novel preprocedural magnetic resonance imaging (MRI) histology protocol for identifying lesions that might present a higher rate of immediate and midterm PVI failure. METHODS We enrolled 22 patients (13 females, average age 65.8 ± 9.72 years) scheduled for PVI were prospectively and underwent 3T MRI using ultrashort echo time and steady-state free precession contrasts to characterize target lesions before PVI. Lesions were scored as hard if >50% of the lumen was occluded by hard components (calcium/dense collagen) on MRI in the hardest cross-section. Two readers evaluated MRI datasets. Trans-Atlantic Inter-Society Consensus Document on Management of Peripheral Arterial Disease (TASC)/Global Limb Anatomic Staging System (GLASS)/Wound, Ischemia and Foot infection scoring was performed based on intraprocedural angiograms and chart review. The relationship between MRI scoring, TASC/GLASS scoring, and procedural outcomes was investigated using univariate analysis. Midterm follow-up (revascularization and amputation rates) was recorded at 3 and 6 months after the intervention. RESULTS Our cohort of 22 patients yielded 40 target lesions. Five lesions were excluded (two for nondiagnostic image quality; three PVIs were ultimately diagnostic only). Six lesions (17%) were scored as hard. MRI-scored hard lesions had a higher proportion of immediate technical failure (hard vs soft 83% [5/6] vs 3% [1/29]; P < .001). Hard vs soft MRI scoring was the only factor significantly associated with immediate PVI technical success (P < .001), as opposed to TASC/GLASS scoring. Both at 3 months and 6 months after PVI, the reintervention rate was significantly higher among those lesions which were scored hard on MRI (3 months hard, 80% vs soft, 16% [P =.011]; 6 months hard, 80% vs soft, 27%; P = .047). CONCLUSIONS MRI histology could be a valuable tool for optimizing PVI patient selection and treatment strategies.

Abstract
OBJECTIVE Most individuals with lower extremity peripheral artery disease (PAD) experience symptoms other than claudication and live with undiagnosed PAD yet no tools exist to detect atypical PAD symptoms. The purpose of this study was to identify discriminating PAD symptom descriptors from a community-based sample of patients with no current diagnosis of PAD. METHODS Symptoms descriptors were obtained in a sample of 22 participants with persistent lower extremity symptoms pre/post exercise. An ankle brachial index with exercise was used to classify participants as "PAD" or "No PAD." RESULTS Thirteen (59%) participants had a positive ankle brachial index (<0.9, ≥20% drop postexercise, or 30 mmHg drop postexercise). Symptoms do not disappear while walking, trouble keeping up with friends/family, positive response to pain or discomfort while sitting, and pain outside of the calves and thighs were associated with a positive ankle brachial index. CONCLUSION Atypical symptoms were common among study participants. Symptoms while sitting and symptoms outside of the calf and thigh were negatively associated with a positive ankle brachial index. More precise descriptions of symptom characteristics are needed to improve PAD symptom recognition.

Abstract
BACKGROUND For chronic limb-threatening ischemia, revascularization has been reported for occlusions but not for stenosis in the inframalleolar (IM) lesions. We investigated the clinical outcomes of balloon dilation for stenotic IM lesions distal to the treatment target in the infrapopliteal (IP) legion. METHODS We conducted a retrospective analysis of patients who had chronic limb-threatening ischemia and underwent revascularization of stenotic IM lesions distal to the target IP lesions between January 2015 and August 2022. The outcome measures were amputation-free survival, wound healing rate, and freedom from target IM reintervention. RESULTS The 87 patients had a mean age of 72.7 ± 10.7 years and comprised 67.8% men, 74.7% with diabetes mellitus, 55.2% on dialysis, 33.3% who had Rutherford six classification. The amputation-free survival (AFS), wound healing, and freedom from target IM reintervention rates at 1 year were 82.9%, 53.3%, and 58.4%, respectively. On Cox proportional multivariate analysis, the predictors were Wound, Ischemia, and foot Infection (WIfI) ≥3 and diffuse stenosis in the target IM vessels for delayed wound healing and Global Limb Anatomic Staging System stage Ⅲ and ≥3 diseased IM vessels before endovascular therapy for target IM reintervention. At the time of reintervention, the lesion morphology had progressed from stenosis to occlusion in 50% of cases. CONCLUSIONS In patients with chronic limb-threatening ischemia, revascularization of stenosis in IM lesions showed a high reintervention rate and progression of lesion morphology, although AFS and wound-healing rates were acceptable.

Abstract
INTRODUCTION Cardiovascular disease represents the foremost cause of death among chronic and non-transmissible diseases. Diagnostic tools commonly used for peripheral and carotid atherosclerosis, such as ankle-brachial index (ABI) and carotid ultrasonography (CU), may contribute as surrogates for the diagnosis of coronary arterial disease (CAD). MATERIAL AND METHODS We report a cross-sectional study of 50 patients referred to elective invasive coronary angiography (ICA). Patients were submitted to ABI and CU-for carotid intima-media thickness (CIMT) and carotid atherosclerotic plaque screening (CAPS). Clinical and demographic variables were also evaluated. CAD was defined as greater than 50% stenosis in at least one coronary artery. RESULTS In logistic regression analysis, only CAPS showed a statistically significant area under the curve (AUC) for CAD prediction: 0.812 (95% CI, p <0.001). ABI and CIMT did not show statistically significant performance. For multivariate logistic regression analysis, the model including variables "gender," "dyslipidemia," "smoking," "pack-years," and CAPS predicted CAD better. The AUC for this model was 0.912 (95% CI, p = 0.002). CONCLUSION The screening for carotid atherosclerotic plaques may enhance traditional risk stratification strategies for CAD. Longitudinal studies and bigger samples of subject are needed to allow extrapolation of our findings.

J Vasc Surg 2024:S0741-5214(24)01786-5. [PMID: 39208919 DOI: 10.1016/j.jvs.2024.08.032] [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: 05/20/2024] [Revised: 08/03/2024] [Accepted: 08/18/2024] [Indexed: 09/04/2024]
Abstract
BACKGROUND Endovascular therapy (ET) outcomes for femoropopliteal peripheral arterial disease (FP-PAD) remain suboptimal. Cilostazol therapy may improve patency rates and decrease major adverse limb events after ET for FP-PAD. Our goal was to analyze published studies evaluating the use of cilostazol after ET for FP-PAD. METHODS We searched MEDLINE, EMBASE, and CENTRAL for randomized and observational studies (OSs) evaluating cilostazol therapy after ET for FP-PAD. We only included OSs adjusting for confounding variables. We analyzed observational and randomized studies separately and explored heterogeneity by estimating an I2 statistic. A fixed-effects model was chosen if the I2 statistic was low. If the two-sided probability of observing the difference between groups under a true null hypothesis was <5%, we considered this difference statistically significant. RESULTS We screened 2171 studies and included 26 papers in our analysis (5 randomized controlled trials and 21 OSs). All randomized studies were open label. In randomized studies, the odds of restenosis were lower in patients treated with cilostazol (pooled odds ratio, 0.28; 95% confidence interval [CI], 0.18-0.43; P < .01; I2 = 0%). The odds of target lesion revascularization (TLR) were also lower in patients treated with cilostazol (pooled odds ratio, 0.35; 95% CI, 0.22-0.65; P < .01; I2 = 0%). In OSs, we also identified associations between peri-interventional treatment with cilostazol and lower rates of restenosis (pooled hazard ratio [pHR], 0.57; 95% CI, 0.51-0.65; P < .01; I2 = 34%), TLR (pHR, 0.53; 95% CI, 0.36-0.79; P < .01; I2 = 0%), and amputation (pHR, 0.54; 95% CI, 0.32-0.90; P = .02; I2 = 30%). CONCLUSIONS In randomized open-label studies, peri-interventional treatment with cilostazol after ET for FP-PAD decreased the odds of restenosis and TLR (Level 1A). Similarly, in OSs that adjusted for confounding, peri-interventional cilostazol therapy was associated with lower rates of restenosis, TLR, and amputation (Level 2A).

Abstract
BACKGROUND The introduction of radial-specific equipment has made transradial (TR) aortoiliac (AI) endovascular therapy (EVT) more convenient. OBJECTIVES The authors aimed to investigate the perioperative outcomes of the TR approach in patients undergoing AI EVT for symptomatic peripheral artery disease. METHODS The COMFORT (Contemporary Strategy for Aortoiliac Intervention) registry was a prospective, multicenter, observational study enrolling patients with symptomatic peripheral artery disease undergoing AI EVT between January 2021 and June 2023. The primary outcome was perioperative complications, whereas the secondary outcomes included core laboratory-evaluated residual stenosis >30%, time to hemostasis, time to ambulation, 30-day patency, and 30-day limb symptoms. These outcomes were compared between TR and non-TR AI EVT after propensity score matching. RESULTS The TR approach was selected for 231 of the 947 patients (24.3%). The TR approach was chosen more in patients with a higher ankle-brachial index, chronic total occlusion, aortic lesion, bare nitinol stent implantation, and plain angioplasty, whereas it was chosen less in patients with dialysis, a history of AI EVT, chronic limb-threatening ischemia, bilateral calcification, and simultaneous infrainguinal EVT (all P < 0.05). After propensity score matching, the incidence of perioperative complications did not differ significantly between the groups (TR group: 6.0% vs non-TR group: 5.1%; P = 0.69). The proportions of residual stenosis, 30-day patency, and 30-day limb symptoms were not significantly different (all P > 0.05); however, the time to hemostasis and the time to ambulation were shorter in the TR group (both P < 0.05). CONCLUSIONS Non-TR AI EVT and TR AI EVT using radial-specific equipment were associated with a similar risk of perioperative complications. The TR approach helps shorten the time required for hemostasis and ambulation.

Abstract
Critical limb ischemia (CLI) is the most severe form of peripheral arterial disease, significantly impacting quality of life, morbidity and mortality. Common complications include severe limb pain, walking difficulties, ulcerations and limb amputations. For cases of CLI where surgical or endovascular reconstruction is not possible or fails, spinal cord stimulation (SCS) may be a treatment option. Currently, SCS is primarily prescribed as a symptomatic treatment for painful symptoms. It is used to treat intractable pain arising from various disorders, such as neuropathic pain secondary to persistent spinal pain syndrome (PSPS) and painful diabetic neuropathy. Data regarding the effect of SCS in treating CLI are varied, with the mechanism of action of vasodilatation in the peripheral microcirculatory system not yet fully understood. This review focuses on the surgical technique, new modalities of SCS, the mechanisms of action of SCS in vascular diseases and the parameters for selecting CLI patients, along with the clinical outcomes and complications. SCS is a safe and effective surgical option in selected patients with CLI, where surgical or endovascular revascularization is not feasible.

Abstract
PURPOSE To present a novel technique for the treatment of heavily calcified aorto-iliac disease using intravascular lithotripsy (IVL) and self-expanding bare-metal stents (BMS). TECHNIQUE We present our experience with 4 cases of calcified aorto-iliac disease that were treated with IVL as vessel preparation followed by BMS deployment. Intravascular lithotripsy was performed using a 7-mm or 8-mm Shockwave catheter from 1 access and a non-compliant balloon introduced from the second access in a "hugging-balloon" configuration. Afterward, a self-expandable BMS is deployed in the infrarenal aorta and additional bare-metal balloon-mounted stents are deployed in the iliac arteries as needed. This technique provides a low-profile solution with only 6- and 7-French introducers, preservation of the collateral circulation while also preserving the option for an up-and-over approach in the future. Technical success was achieved in all cases and no periprocedural complications were observed. CONCLUSION Intravascular lithotripsy in combination with BMS for the infrarenal aorta and the aortic bifurcation seems to be a safe and effective low-profile treatment option for heavily calcified lesions. Large-scale studies with long-term follow-up are needed to validate our positive early results. CLINICAL IMPACT Endovascular treatment of heavily calcified aortoiliac disease poses significant challenges, including the risk of rupture and dissection. The proposed technique uses intravascular lithotripsy and bare-metal stenting of the aortic bifurcation and represents a low-profile solution that preserves collaterals and potentially reduces the risk of dissection with IVL vessel preparation.

Abstract
The current treatment options for peripheral arterial disease (PAD) are limited due to a lack of significant high-level evidence to inform clinical decisions and unfavorable outcomes in terms of cost-effectiveness and amputation rates. In order to suggest the use of the commercially available L-Ornithine-L-Aspartate (LOLA) for treating PAD, we induced hind limb ischemia (HLI) by unilaterally ligating the femoral artery in a rat model. The rats were randomly divided into three groups, with seven rats assigned to each group: group 1 (control), group 2 (sorbitol), and group 3 (LOLA). Intraperitoneal injections were administered five times on post-operative days (PODs) 3, 5, 7, 10, and 12. Perfusion imaging was conducted on PODs 7 and 14 and compared to pre-operative perfusion imaging. Immunohistochemistry staining and Western blotting were performed after the final perfusion imaging. Group 3 showed a significant increase in perfusion, high CD31-positive capillary lumen density, and substantial overexpression of VEGF in the ischemic limb during the subacute phase of HLI. In conclusion, this study provides the first documented evidence of angiogenesis and perfusion recovery in the subacute phase of the HLI model following the administration of LOLA. With LOLA readily available on the commercial market, the implementation of LOLA treatment for PAD in humans can be expedited compared to other therapies still in the developmental stage.

Abstract
PURPOSE Although endovascular therapy (EVT) is considered a vital strategy for treating infrapopliteal lesions in chronic limb-threatening ischemia (CLTI), the recurrence rate after EVT exceeds that after bypass surgery (BSX). The optimal approach for managing infrapopliteal lesion recurrence in patients with CLTI and unhealed ulcers remains uncertain. This study aimed to evaluate the clinical outcomes of repeat EVT and subsequent inframalleolar BSX for CLTI with infrapopliteal lesion recurrence. MATERIALS AND METHODS We conducted a retrospective analysis of 140 patients with CLTI (mean age, 70±10 years; male, 71.4%; diabetes mellitus, 73.6%; dialysis, 74.3%; Rutherford 5, 79.3%; and Rutherford 6, 20.7%) who had an unhealed wound due to the recurrence of infrapopliteal lesions between January 2015 and May 2020. We compared the clinical outcomes of 40 patients who underwent the subsequent inframalleolar BSX with those of 100 patients who underwent repeat EVT. The outcome measures were amputation-free survival (AFS) and wound healing rate. Propensity score matching analysis was conducted to minimize differences in baseline characteristics. RESULTS Propensity score matching extracted 38 pairs (38 patients in the subsequent BSX group and 83 patients in the repeat EVT group). AFS was not significantly different between the repeat EVT and subsequent BSX groups (81.9% vs 82.6% at 1 year, p=0.97). Neither was cumulative wound healing (42.8% vs 43.3% at 1 year, p=0.55). No baseline characteristics had any significant interaction effect on the association between repeat EVT, subsequent BSX, and failure of AFS. CONCLUSION This study using propensity score matching revealed that the clinical outcomes following repeat EVT were comparable with those following subsequent inframalleolar BSX, indicating that repeat EVT may be a viable treatment option for CLTI with infrapopliteal lesion recurrence. CLINICAL IMPACT Although endovascular therapy (EVT) has expanded the treatment options for chronic limb-threatening ischemia (CLTI), the recurrence rate after EVT is higher than that after bypass surgery (BSX). This retrospective study compared the clinical outcomes of repeat EVT with those of subsequent BSX for CLTI with infrapopliteal lesion recurrence. After propensity score matching, amputation-free survival (AFS) was not significantly different between the repeat EVT and subsequent BSX groups (81.9% vs 82.6% at 1 year, p=0.97). Neither was cumulative wound healing (42.8% vs 43.3% at 1 year, p=0.55). There was no difference between the 2 revascularization strategies when treating infrapopliteal restenosis lesions.

Abstract
Background Peripheral artery disease is a common condition caused by narrowing/blockage of the arteries, resulting in reduced blood supply. Peripheral artery disease is associated with an increased risk of vascular complications, but early treatment reduces mortality and morbidity. Leg ulcers are long-lasting wounds, usually treated by compression therapy. Compression therapy is not suitable for people with peripheral artery disease, as it can affect the arterial blood supply. In clinical practice, people with peripheral artery disease are identified by measurement of the ankle-brachial pressure index using a sphygmomanometer and manual Doppler device. However, this method can be uncomfortable for people with leg ulcers and automated devices have been proposed as a more acceptable alternative. The objective of this appraisal was to summarise the clinical and cost-effectiveness evidence on the use of automated devices to detect peripheral artery disease in people with leg ulcers. Methods . Clinical effectiveness To identify reports of relevant studies, we searched major electronic databases and scrutinised the information supplied by the manufacturers of the automated devices under investigation. Due to the lack of evidence on people with leg ulcers, we considered evidence from studies of any design assessing automated devices versus an acceptable reference device in any population receiving ankle-brachial pressure index assessment. We summarised information on diagnostic accuracy of the automated devices and level of agreement with the reference device. For each device, when data permit, we pooled data across studies by conducting random-effects meta-analyses using a Hierarchical Summary Receiving Operating Characteristics model. Cost-effectiveness An economic model comprising a decision tree (24 weeks) and Markov models to capture lifetime costs and quality-adjusted life-years associated with venous, arterial and mixed aetiology disease in leg ulcer patients. Analyses were conducted from a United Kingdom National Health Service and Personal Social Services perspective. Costs and quality-adjusted life-years were discounted at 3.5% per year. Deterministic and several probabilistic analyses were used to capture uncertainty surrounding a range of optimistic and pessimistic assumptions about the impact of automated tests on health outcomes (ulcer healing and requirement for invasive management of arterial disease). Results . Clinical effectiveness From the 116 records retrieved by the electronic searches, we included 24 studies evaluating five devices (BlueDop Vascular Expert, BOSO ABI-System 100, Dopplex Ability, MESI ankle-brachial pressure index MD and WatchBP Office ABI). Two studies assessing people with leg ulcers found that automated devices often gave higher ankle-brachial pressure index readings than manual Doppler (underestimation of arterial disease). In the 22 studies involving people without leg ulcers, automated devices generally demonstrated good specificity and moderate specificity. Meta-analysis of 12 studies showed a pooled sensitivity of 64% (95% confidence interval 57% to 71%) and a pooled specificity of 96% (95% confidence interval 92% to 98%) for detection of peripheral artery disease. Cost-effectiveness Automated devices cost less than manual Doppler to deliver. However, increased risks of invasive treatment requirements for inappropriately compressed arterial/mixed ulcers due to false-negative results, and increased healing times due to delayed compression of false-positive test results mean that in most scenarios manual Doppler was less costly and had slightly higher quality-adjusted life-years than automated devices. Results are highly uncertain, dependent on many assumptions and should be interpreted cautiously. Limitations and conclusions The limited evidence identified for each automated device, especially in people with leg ulcers, and its clinical heterogeneity precludes any firm conclusions on the diagnostic performance and cost-effectiveness of these devices in clinical practice.

Abstract
OBJECTIVE In two randomized controlled trials, the outcomes of endovascular treatment of complex femoropopliteal arterial lesions were compared with bypass surgery and considered a valid alternative treatment. The aim of this study was to compare both endovascular treatment options with the hypothesis that implantation of heparin-bonded self-expanding covered stents (Viabahn [SECS]) or drug-eluting stents (ZilverPTX [DES]) are related to similar clinical outcomes at 1-year follow-up. METHODS In a post-hoc analysis, the SuperB trial and Zilverpass databases were merged. Patients in the endovascular treatment arms were included, and data was analyzed in an intention-to-treat (ITT) and a per-protocol (PP) fashion. Data included baseline and lesion characteristics, procedural details, and follow-up data. The primary endpoint of this study was primary patency at 1-year follow-up. The secondary endpoints were secondary patency, target lesion revascularization (TLR), limb loss, and all-cause mortality. RESULTS A total of 176 patients were included; 63 in the SECS arm and 113 in the DES arm. Through 1-year follow-up, there were no significant differences in primary patency (ITT: 63.4% vs 71.1%: P = .183 and PP: 60.8% vs 71.1%; P = .100). Secondary patency rates were not significantly different in the ITT analysis (86.5% vs 95.1%; P = .054), but in the PP analysis, there was a significant difference in favor of the DES group (SECS, 85.6% vs DES, 95.1%; P = .038). There was no significant difference in freedom from TLR between groups (79.6% vs 77.0%; P = .481). No major amputations were performed in the SECS group, and two were performed in the DES group (1.8%). Survival rate was 98.2% in the SECS group, and 91.3% in the DES group after 1-year follow-up (P = .106). Based on diagnosis (intermittent claudication vs chronic limb-threatening ischemia) no differences between patients with intermittent claudication and chronic limb-threatening ischemia were observed in primary patency, secondary patency and freedom from TLR. CONCLUSIONS Treatment of complex femoropopliteal arterial disease with the heparin-bonded Viabahn endoprosthesis and the Zilver PTX drug-eluting stent are related to similar primary and secondary patency, and TLR rates at 1 year, except for secondary patency in the PP analysis. This study further supports the endovascular treatment of long complex lesions in the femoropopliteal artery.

Abstract
BACKGROUND Endovascular treatment is nowadays accepted as first-line treatment for most patients with aorto-iliac obstructive disease (AIOD), including those with Trans-Atlantic Inter-Society Consensus II (TASC-II) lesion types C and D. Aim of the study was to evaluate the role of Viabahn VBX (W. L. Gore and Associates, Flagstaff, AZ, USA), in patients with chronic occlusive aorto-iliac disease (ChO). METHODS A retrospective review of patients undergone elective endovascular repair with VBX (W. L. Gore and Associates) for ChO at five referral vascular institutions in Italy from 2018 to 2022 was conducted. Primary endpoints were technical success and the incidence of any early and midterm procedure-related reintervention. Secondary endpoints were clinical success, primary and secondary patency. RESULTS Among 89 included patients, technical success was obtained in 87 patients (97.8%). Postoperative complication requiring early surgical reintervention was necessary in 5 (6%), all but one for arterial bleeding. Clinical improvement of at least 3 classes was observed in 49 (55%). After a mean follow-up of 24.1 months ±14.1, primary patency and freedom from any procedure-related reintervention at 12, 24 and 36 months was 83.0% and 94.8%, 80.0% and 91.5%, 77.9% and 89.3%, respectively. Secondary patency was 100%. TASC-II D lesion (OR=3.67, 95% CI: 1.1289-11.9823, P=0.03) and Grade III iliac calcification (OR=3.41, 95% CI: 1.0944-10.6428, P=0.03) were identified as independent predictors for procedure-related reintervention. CONCLUSIONS Use of VBX (W. L. Gore and Associates) in ChO was safe and effective with low rate of stenosis/occlusion in the early and mid-term follow-up. TASC-II D and Grade III calcifications resulted as independent predictors for procedure-related reintervention.

Abstract
Open surgical repair, often in the form of endarterectomy, is still the gold standard for steno-occlusive disease in the common femoral artery, despite the success of lower-risk endovascular alternatives in other peripheral arterial regions. Stenting in the common femoral artery is not widely adopted due to the proximity of the artery to the mobile hip joint, and the perceived risk this has on the stent structure due to kinking. The purpose of this review was to assess how hip movement contributes to the anatomical and biomechanical challenges proposed in the common femoral artery, and how these challenges impact the hemodynamics with both open surgical and endovascular stent treatments. The findings demonstrated that the common femoral artery is a fixed arterial segment which does not bend or twist as previously perceived. However, high degrees of bending and twisting are evident in the vessels directly proximal and distal to the common femoral artery. Mechanical testing suggests that the latest generation braided Nitinol stents could be well-suited to these challenges. Both endarterectomy and stenting provide good hemodynamic results regarding limb perfusion. However, other hemodynamic parameters, such as wall shear stress, may not be optimized with either modality, increasing the risk of chronic restenosis. As a high proportion of common femoral artery disease extends into the adjacent arterial segments, further research is warranted to ascertain the optimum hemodynamic stent configuration, as a lower-risk alternative to open surgery.

Abstract
BACKGROUND Covered endovascular reconstruction of aortic bifurcation (CERAB) is increasingly used as a first line-treatment in patients with aortoiliac occlusive disease (AIOD). We sought to compare the outcomes of patients who underwent CERAB compared with the gold standard of aortobifemoral bypass (ABF). METHODS The Vascular Quality Initiative was queried for patients who underwent ABF or CERAB from 2009 to 2021. Propensity scores were generated using demographics, comorbidities, Rutherford class, and urgency. The two groups were matched using 5-to-1 nearest-neighbor match. Our primary outcomes were 1-year estimates of primary patency, major adverse limb events (MALEs), MALE-free survival, reintervention-free survival, and amputation-free survival. Standard statistical methods were used. RESULTS A total of 3944 ABF and 281 CERAB cases were identified. Of all patients with AIOD, the proportion of CERAB increased from 0% to 17.9% between 2009 and 2021. Compared with ABF, patients who underwent CERAB were more likely to be older (64.7 vs 60.2; P < .001) and more often had diabetes (40.9% vs 24.1%; P < .001) and end-stage renal disease (1.1% vs 0.3%; P = .03). In the matched analysis (229 CERAB vs 929 ABF), ABF patients had improved MALE-free survival (93.2% [±0.9%] vs 83.2% [±3%]; P < .001) and lower rates of MALE (5.2% [±0.9%] vs 14.1% [±3%]; P < .001), with comparable primary patency rates (98.3% [±0.3%] vs 96.6% [±1%]; P = .6) and amputation-free survival (99.3% [±0.3%] vs 99.4% [±0.6%]; P = .9). Patients in the CERAB group had significantly lower reintervention-free survival (62.5% [±6%] vs 92.9% [±0.9%]; P < .001). Matched analysis also revealed shorter length of stay (1 vs 7 days; P < .001), as well as lower pulmonary (1.2% vs 6.6%; P = .01), renal (1.8% vs 10%; P < .001), and cardiac (1.8% vs 12.8%; P < .001) complications among CERAB patients. CONCLUSIONS CERAB had lower perioperative morbidity compared with ABF with a similar primary patency 1-year estimates. However, patients who underwent CERAB experienced more major adverse limb events and reinterventions. Although CERAB is an effective treatment for patients with AIOD, further studies are needed to determine the long-term outcomes of CERAB compared with the established durability of ABF and further define the role of CEARB in the treatment of AIOD.

Abstract
OBJECTIVE Most surgeons employ an endovascular-first approach to the treatment of peripheral arterial disease (PAD), but controversy remains regarding the ideal interventions for the management of isolated popliteal artery disease (IPAD). Indeed, there are a paucity of data that compare outcomes of popliteal stents vs other peripheral vascular interventions (PVIs). The goal of this study was to evaluate outcomes of PVIs in IPAD. METHODS The Vascular Study Group of New England database was queried for all IPAD PVIs performed for atherosclerotic occlusive disease from 2010 to 2021. Those with at least 1 year of follow-up data available were included for analysis. The primary endpoint was 1-year freedom from a composite target lesion (TL) treatment failure that included restenosis >50% on duplex, reintervention, or ipsilateral major amputation. RESULTS We included 689 procedures performed on 634 patients. Of these, 250 (36.3%) were treated with plain balloons (POBA), 215 (31.2%) had stents, 170 (24.7%) had special balloons (drug-coated, cutting, or lithotripsy), and 54 (7.8%) atherectomies were performed. Stent placement was associated with lower freedom from TL treatment failure (72.6%) than special balloon (81.2%; P = .048) and atherectomy (88.9%; P = .012), but not POBA (76.8%; P = .293). On multivariable logistic regression, stents (odds ratio, 0.637; P = .021) and preoperative P2Y12 inhibitor therapy (odds ratio, 0.683; P = .048) were both associated with lower freedom from intervention failure. CONCLUSIONS Popliteal stent placement is associated with a higher rate of TL treatment failure at 1 year when compared with other PVIs including special balloon angioplasty and atherectomy, but not POBA, and should therefore be avoided in favor of special balloons or atherectomy whenever feasible.

Abstract
INTRODUCTION Black persons bear a disproportionate burden of peripheral artery disease (PAD) and experience higher rates of endovascular revascularization failure (ERF) when compared with non-Hispanic White persons. We aimed to identify predictors of ERF in Black persons using predictive modeling. METHODS This retrospective study included all persons identifying as Black who underwent an initial endovascular revascularization procedure for PAD between 2011 and 2018 at a midwestern tertiary care center. Three predictive models were developed using (1) logistic regression, (2) penalized logistic regression (least absolute shrinkage and selection operator [LASSO]), and (3) random forest (RF). Predictive performance was evaluated under repeated cross-validation. RESULTS Of the 163 individuals included in the study, 113 (63.1%) experienced ERF at 1 y. Those with ERF had significant differences in symptom status (P < 0.001), lesion location (P < 0.001), diabetes status (P = 0.037), and annual procedural volume of the attending surgeon (P < 0.001). Logistic regression and LASSO models identified tissue loss, smoking, femoro-popliteal lesion location, and diabetes control as risk factors for ERF. The RF model identified annual procedural volume, age, PAD symptoms, number of comorbidities, and lesion location as most predictive variables. LASSO and RF models were more sensitive than logistic regression but less specific, although all three methods had an overall accuracy of ≥75%. CONCLUSIONS Black persons undergoing endovascular revascularization for PAD are at high risk of ERF, necessitating need for targeted intervention. Predictive models may be clinically useful for identifying high-risk patients, although individual predictors of ERF varied by model. Further exploration into these models may improve limb salvage for this population.

Abstract
Critical limb ischemia (CLI) is a state of severe peripheral artery disease, with no effective treatment. Cell therapy has been investigated as a therapeutic tool for CLI, and pericytes are promising therapeutic candidates based on their angiogenic properties. We firstly generated highly proliferative and immunosuppressive pericyte-like cells from embryonic stem (ES) cells. In order to enhance the angiogenic potential, we transduced the basic fibroblast growth factor (bFGF) gene into the pericyte-like cells and found a significant enhancement of angiogenesis in a Matrigel plug assay. Furthermore, we evaluated the bFGF-expressing pericyte-like cells in the previously established chronic hindlimb ischemia model in which bone marrow-derived MSCs were not effective. As a result, bFGF-expressing pericyte-like cells significantly improved blood flow in both laser Doppler perfusion imaging (LDPI) and dynamic contrast-enhanced MRI (DCE-MRI). These findings suggest that bFGF-expressing pericyte-like cells differentiated from ES cells may be a therapeutic candidate for CLI.

Abstract
BACKGROUND/OBJECTIVE The endovascular approach is the first choice of treatment in high-risk patients suffering from Leriche syndrome. Although many techniques and devices have been developed, there are still difficulties in accessing the true lumen. Herein, we reported a novel technique to increase the support and ease of crossing the lesion. METHOD We presented a case report of a 45-year-old male patient with Leriche syndrome. The patient refused surgery; therefore, he was scheduled for endovascular treatment. RESULTS We attempted to cross the right and left common iliac occlusions by intraluminal crossing. The left common iliac artery couldn't be cannulated despite the stiff wires and percutaneous intentional extraluminal revascularization (PIER). Afterward, a cross-over approach was performed from the right side to reach the ostium of the left common iliac artery. To increase the support, a non-absorbable suture was stitched up to the tip of the guiding catheter and kept slightly taut like a lasso. Finally, successful penetration was achieved with the novel assistive technique. CONCLUSION Endovascular treatment for Leriche syndrome is a precious alternative to open surgery. Intraluminal crossing, PIER, and re-entry devices are the most preferred techniques. Increasing the technical success of intraluminal crossing and PIER leads to an apparent reduction in cost.

Abstract
BACKGROUND Endovascular treatment (EVT) for aortoiliac (AI) occlusive lesions is now conducted worldwide, but there are challenges in EVT for complex AI lesions. The VIABAHN VBX (W.L. Gore & Associates, Flagstaff, AZ) is a next-generation balloon-expandable covered stent designed for use with complex AI lesions. The purpose of this study is to evaluate the medium-term outcomes of VIABAHN VBX for such lesions. METHODS Symptomatic patients who underwent EVT with VIABAHN VBX for an AI lesion from 2018 to 2020 at 7 Japanese centers were reviewed retrospectively. The primary endpoints were primary patency and freedom from target lesion revascularization (TLR). RESULTS A total of 95 EVT procedures with VIABAHN VBX for AI occlusive lesions were performed in 71 patients. The patients had high rates of dyslipidemia (53%) and chronic kidney disease (61%), and 22% had chronic limb-threatening ischemia (CLTI). The Transatlantic Inter-Society Consensus (TASC Ⅱ) class was A in 12 patients (17%), B in 12 (17%), C in 10 (14%), and D in 37 (52%). Severe calcification (360°) of the treated lesion was present in 31 patients (33%). The median procedure time was 84 (49-158) min, with a technical success rate of 100%. The median follow-up period was 36 (32-43) months. The 3-year primary and secondary patency of VIABAHN VBX were 91% and 99%, the 3-year freedom from TLR was 92%, and the 3-year freedom from major adverse limb event (MALE) was 98%. No limbs required major amputation. Lesion severity (TASC Ⅱ C or D) and severe calcification did not affect the primary patency or freedom from TLR. CONCLUSIONS Medium-term outcomes after EVT with VIABAHN VBX for AI lesions were acceptable regardless of lesion severity and calcification. These results suggest that VIABAHN VBX may be suitable for AI occlusive lesions with severe anatomical complexity and/or severe calcification.

Abstract
OBJECTIVE Predictive value of systemic immune-inflammation index (SII) has been shown in clinical outcomes and complexity of coronary artery disease, acute coronary syndrome, and heart failure. We sight to evaluate value of SII in patients with lower extremity arterial disease (LEAD). METHODS A total of 271 patients diagnosed with LEAD were included to our study. Blood samples of the patients were collected and analyzed for biochemical variables and complete blood count parameters. SII value of each patient was calculated. The complexity of atherosclerotic disease was classified according to Trans-Atlantic Inter-Society Consensus (TASC II) classification. RESULTS Patients with TASC C-D were older than patients in TASC A-B group (63.06 ± 9.24 years and 60.85 ± 8.75 years, respectively). Other co-morbidities were comparable in both groups. Hemoglobin level and lymphocyte count were significantly lower, neutrophil, platelet counts, and SII values were significantly higher in patients with TASC C-D disease compared to that of patients with TASC A-B disease. SII showed significant correlation with the severity of LEAD (r = 0.363, p < .001). SII value of 664.24 predicted TASC C-D disease with a sensitivity and specificity of 60.8% and 73.3%, respectively. Results of multivariate logistic regression analysis showed that SII had higher odds ratio compared to platelet, neutrophil, and lymphocyte counts. CONCLUSION Higher SII may indicate probability of more complex LEAD. This relationship seems plausible in terms of similar pathophysiology of coronary artery disease and peripheral artery disease.

Comparative outcomes of aortobifemoral bypass with or without previous endovascular kissing stenting of the aortoiliac bifurcation. J Vasc Surg 2024; 80:451-458.e1. [PMID: 38537877 DOI: 10.1016/j.jvs.2024.03.027] [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: 12/28/2023] [Revised: 03/17/2024] [Accepted: 03/19/2024] [Indexed: 04/23/2024]
Abstract
OBJECTIVE The aim of this multicenter national study was to compare the outcomes of primary open surgery by aorto-bifemoral bypass (ABFB) with those performed after a failed endovascular treatment (EVT) by kissing stent technique for complex aortoiliac occlusive disease (AIOD) lesions (TransAtlantic Inter-Society Consensus [TASC] II C and D). METHODS All consecutive ABFB cases carried out at 12 vascular surgery centers between 2016 and 2021 were retrospectively collected and analyzed. Data included patients' baseline demographics and clinical characteristics, procedural details, perioperative outcomes, and follow-up results (survival, patency, amputation). The study cohort was divided into two groups based on indications for ABFB: primary treatment vs secondary treatment after EVT failure. RESULTS Overall, 329 patients underwent ABFB during the study period (71% males; mean age, 64 years), of which 285 were primary treatment and 44 were after prior EVT. At baseline, no significant differences were found between study groups in demographics and clinical characteristics. TASC C and D lesions were similarly represented in the study groups (TASC C: 22% vs 78%; TASC D: 16% vs 84%). No major differences were found between study groups in terms of procedural details, early mortality, and perioperative complications. At 5 years, primary patency rates were significantly higher for primary ABFB (88%; 95% confidence interval [CI], 93.2%-84%) as compared with ABFB after prior EVT (69%; 95% CI 84.9%-55%; log rank P value < .001); however, the 5-year rates of secondary patency (100% vs 95%; 95% CI, 100%-86%) and limb salvage (97%; 95% CI, 99%-96 vs 97%; 95% CI, 100%-94%) were similar between study groups. CONCLUSIONS Surgical treatment of TASC C/D AIOD with ABFB seems to be equally safe and effective when performed after prior EVT, although primary ABFB seemed to have higher primary patency rates. Despite the need for more frequent reinterventions, secondary patency and limb salvage rates were similar. However, future large prospective trials are required to confirm these findings.

Abstract
Aortoiliac occlusive disease (AIOD) is a specific form of peripheral artery disease (PAD) that affects the infrarenal aorta and iliac arteries. Patients with PAD commonly suffer from intermittent claudication (IC), a condition characterized by cramping pain during or after exercise that is relieved by rest. The first-line therapy for IC involves medical management, foot care, and structured exercise programs while revascularization therapy, which can be endovascular, surgical, or a combination of both, is generally reserved for patients with claudication who do not respond adequately to initial therapies. We present the clinical case of a 58-year-old female with hypertension, dyslipidemia, and a smoking habit who was referred to our hospital (Misericordia Hospital, Grosseto, Italy) due to bilateral IC of the buttocks and thighs. Computed tomography (CT) angiography revealed a 90% tight stenosis of the infrarenal abdominal aorta just above the iliac bifurcation with diffuse calcifications. After a careful evaluation of the patient's condition and anatomical characteristics of the atherosclerotic disease, the vascular team decided to perform covered endovascular reconstruction of aortic bifurcation (CERAB) with previous intravascular lithotripsy (IVL) with shockwave balloon using intravascular ultrasound (IVUS) as guidance, because of severe aortic luminal calcifications. We performed successful CERAB, and the patient was discharged in good clinical condition on the fifth day of hospitalization with an indication to follow optimal medical therapy. At the one-month clinical follow-up, the patient reported the disappearance of claudication with marked improvement in quality of life. This first described case of IVUS-guided IVL-facilitated CERAB demonstrates the efficacy and safety of IVL in calcific aortic disease and shows the usefulness of IVUS as guidance in peripheral calcium debulking procedures.

Illness Trajectories After Revascularization in Patients With Peripheral Artery Disease: A Unified Approach to Understanding the Risk of Major Amputation and Death. Circulation 2024; 150:261-271. [PMID: 39038089 DOI: 10.1161/circulationaha.123.067687] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Accepted: 05/08/2024] [Indexed: 07/24/2024]
Abstract
BACKGROUND The aim of this study was to investigate the illness trajectories of patients with peripheral artery disease (PAD) after revascularization and estimate the independent risks of major amputation and death (from any cause) and their interaction. METHODS Data from Hospital Episode Statistics Admitted Patient Care were used to identify patients (≥50 years of age) who underwent lower limb revascularization for PAD in England from April 2013 to March 2020. A Markov illness-death model was developed to describe patterns of survival after the initial lower limb revascularization, if and when patients experienced major amputation, and survival after amputation. The model was also used to investigate the association between patient characteristics and these illness trajectories. We also analyzed the relative contribution of deaths after amputation to overall mortality and how the risk of mortality after amputation was related to the time from the index revascularization to amputation. RESULTS The study analyzed 94 690 patients undergoing lower limb revascularization for PAD from 2013 to 2020. The majority were men (65.6%), and the median age was 72 years (interquartile range, 64-79). One-third (34.8%) of patients had nonelective revascularization, whereas others had elective procedures. For nonelective patients, the amputation rate was 15.2% (95% CI, 14.4-16.0) and 19.9% (19.0-20.8) at 1 and 5 years after revascularization, respectively. For elective patients, the corresponding amputation rate was 2.7% (95% CI, 2.4-3.1) and 5.3% (4.9-5.8). Overall, the risk of major amputation was higher among patients who were younger, had tissue loss, diabetes, greater frailty, nonelective revascularization, and more distal procedures. The mortality rate at 5 years after revascularization was 64.3% (95% CI, 63.2-65.5) for nonelective patients and 33.0% (32.0-34.1) for elective patients. After major amputation, patients were at an increased risk of mortality if they underwent major amputation within 6 months after the index revascularization. CONCLUSIONS The illness-death model provides an integrated framework to understand patient outcomes after lower limb revascularization for PAD. Although mortality increased with age, the study highlights patients <60 years of age were at increased risk of major amputation, particularly after nonelective revascularization.

Abstract
OBJECTIVES Cardio-ankle vascular index (CAVI) is a blood pressure-independent measure of heart-ankle pulse wave velocity and is used as an indicator of arterial stiffness. However, there is a paradox that CAVI is inversely associated with leg ischemia in patients with lower extremity arterial disease (LEAD). The aim of this study was to clarify the significance of the absolute value of left and right difference in CAVI (diff-CAVI). METHODS The subjects were 165 patients with LEAD who had received medication therapy. Relationships between diff-CAVI and leg ischemia were investigated. Leg ischemia was evaluated by decrease in leg arterial flow using ankle-brachial index (ABI) and by symptoms using the Rutherford classification. RESULTS There was a significant inverse correlation between diff-CAVI and ABI. The odds ratio for low ABI of the 3rd versus 1st tertile groups of diff-CAVI was 7.03 with a 95% confidence interval of 2.71 ∼ 18.22. In ROC analysis, the cutoff value of diff-CAVI for low ABI was 1.05 with a sensitivity of 61.1% and a specificity of 87.1%. The median of diff-CAVI was significantly higher in subjects with grade 2 of the Rutherford classification than in subjects with its grade 1. CONCLUSIONS diff-CAVI showed an inverse association with ABI and a positive association with symptoms of leg ischemia. Thus, diff-CAVI is thought to be a useful indicator of leg ischemia in LEAD patients.

Abstract
Peripheral arterial disease (PAD) prevalence and diabetes mellitus (DM) prevalence are continuously increasing worldwide. The strong relationship between DM and PAD is highlighted by recent evidence. PAD diagnosis in diabetic patients is very important, particularly in patients with diabetic foot disease (DFD); however, it is often made difficult by the characteristics of such diseases. Diagnosing PAD makes it possible to identify patients at a very high cardiovascular risk who require intensive treatment in terms of risk factor modification and medical therapy. The purpose of this review is to discuss the diagnostic methods that allow for a diagnosis of PAD in diabetic patients. Non-invasive tests that address PAD diagnosis will be discussed, such as the ankle-brachial index (ABI), toe pressure (TP), and transcutaneous oxygen pressure (TcPO2). Furthermore, imaging methods, such as duplex ultrasound (DUS), computed tomography angiography (CTA), magnetic resonance angiography (MRA), and digital subtraction angiography (DSA), are described because they allow for diagnosing the anatomical localization and severity of artery stenosis or occlusion in PAD. Non-invasive tests will also be discussed in terms of their ability to assess foot perfusion. Foot perfusion assessment is crucial in the diagnosis of critical limb ischemia (CLI), the most advanced PAD stage, particularly in DFD patients. The impacts of PAD diagnosis and CLI identification in diabetic patients are clinically relevant to prevent amputation and mortality.

Abstract
Peripheral arterial disease (PAD) represents one of the most frequent manifestations of atherosclerosis in men and women. In both sexes, PAD is related to classical risk factors of atherosclerosis, which are similarly distributed, but some additional factors determine differences between men and women. More frequent asymptomatic disease in women than in men and less frequent screening in women may result in a false underestimation of the prevalence of PAD in women. All these factors may cause delayed diagnosis and treatment of PAD in women. Estrogen hormones have vasoprotective properties that lower the prevalence of atherosclerosis in women of younger age. However, estrogen probably does not have a protective role against the development of cardiovascular disease in women of an older age. Hormone replacement therapy (HRT) of less than one year does not appear to reduce the odds of developing PAD in postmenopausal women. It may even increase the risk of morbidity from vascular interventions. However, some studies indicated that HRT for more than one year significantly decreases the risk of PAD if administered early after the last menstruation. Also, treatment of PAD in women differs to some extent from men.

Abstract
OBJECTIVE Although high-frequency repetitive transcranial magnetic stimulation (HF-rTMS) has shown benefits in chronic stroke, its application in subacute ischemic stroke remains underexplored. This study aims to investigate the effects and safety of lesion-side HF-rTMS in subacute ischemic stroke. METHODS Prospective lesion-side HF-rTMS was conducted on consecutive ischemic stroke patients within 3 days of onset from February 2019 to June 2022. Inclusion criteria required persistent paralysis (NIHSS score ≥ 1 for at least 7 days). Exclusion criteria comprised cortical infarction, disturbance of consciousness, and age over 80 years. A conventional rehabilitation group meeting the same criteria from June 2015 to January 2019 served as a comparison. We compared the two groups regarding clinical background and outcome. We also evaluated incidence of epilepsy and exacerbation of the NIHSS score in the rTMS group. RESULTS Seventy-eight patients participated, with 50% in the HF-rTMS group. Median time from onset to HF-rTMS initiation was 9 (IQR 7-12) days. A favorable outcome (modified Rankin Scale score 0-2) at 3 months was more frequent in the rTMS group (80% vs. 44%, p = 0.002). HF-rTMS was independently associated with a favorable outcome at 3 months (OR = 5.60, 95% CI = 1.53-20.50, p = 0.009). No cases of epilepsy or exacerbation of NIHSS score were observed. CONCLUSIONS HF-rTMS demonstrates potential effectiveness and safety in subacute ischemic stroke patients.
