Abstract
High incidence of superficial femoral artery (SFA) restenosis after percutaneous transluminal angioplasty (PTA) poses a persistent challenge in peripheral arterial disease (PAD) treatment. We studied how the patients' and lesions' characteristics, thrombin generation, overall haemostatic potential (OHP), and single nucleotide polymorphisms (SNPs) of the NR4A2 and PECAM1 genes affected the likelihood of restenosis. In total, 206 consecutive PAD patients with limiting intermittent claudication due to SFA stenosis who were treated with balloon angioplasty with bailout stenting when necessary were included. Patients' clinical status and patency of the treated arterial segment on ultrasound examination were assessed 1, 6, and 12 months after the procedure. Restenosis occurred in 45% of patients, with less than 20% of all patients experiencing symptoms. In the multivariate analysis, predictors of restenosis proved to be poor infrapopliteal runoff, higher lesion complexity, absence of treated arterial hypertension, delayed lag phase in thrombin generation, and higher contribution of plasma extracellular vesicles to thrombin concentration. Poor infrapopliteal runoff increased the risk of restenosis in the first 6 months, but not later. The negative effect of poor infrapopliteal runoff on SFA patency opens questions about the potential benefits of simultaneous revascularisation of below-knee arteries along with SFA revascularisation.

Abstract
IntroductionCurrent evidence indicates endovascular intervention is a safe and effective treatment for peripheral artery disease of the lower extremity. However, the clinical outcome of endovascular intervention for femoropopliteal lesions has been shown to be affected by the status of tibial runoff. It remains unclear whether endovascular intervention for tibial runoff is associated with additional benefits.Methods and analysisThis prospective, multicenter, real-world observational study is carried out from January 2021 to December 2022 in 8 designated centers across China with an estimated sample size of 1200 patients with severe femoropopliteal disease. The pre-procedural status of tibial runoff is evaluated with the modified SVS score and categorized as good (SVS <5), compromised (SVS 5–10) or poor (SVS >10). Whether the patient will be treated with endovascular intervention for tibial runoff is determined by the treating vascular surgeons. Patients are dichotomized into the intervention group and the non-intervention group, with each group further divided into the good, compromised and poor tibial run-off subgroup, yielding 6 subgroups in total. Patients within various subgroups are compared with regard to the primary patency rate of the femoropopliteal artery, changes in quality of life, changes of Rutherford category, improvement of the Wound, Ischemia, and Foot Infection Classification, and incidence of major adverse events over 24-months follow-up. The results of this study may provide important information to help vascular sspecialists to decide whether the tibial runoff should be endovascularly intervened and which patient population benefits most from tibial runoff intervention.Clinical trial registrationhttps://clinicaltrials.gov/ct2/show/NCT04675632?id=NCT04675632&draw=2&rank=1, NCT04675632.

Abstract
Peripheral artery disease (PAD) is a prevalent condition that confers substantial morbidity and mortality and remains underdiagnosed as well as undertreated in the overall population. Although PAD prevalence is similar or higher in women compared with men, associations of traditional and nontraditional risk factors with PAD and clinical manifestations of PAD differ by sex and may contribute to delayed or lack of diagnosis in women. Such sex-based differences in the manifestation of PAD may arise from sexual dimorphism in the vascular substrate in health as well as sex variation in the responses to vascular stressors. Despite the availability of proven therapies for improving symptoms and reducing risk of ischemic cardiovascular and limb events among patients with diagnosed PAD, important sex differences in treatment and outcomes have been observed. We provide an overview of current knowledge regarding sex differences in the epidemiology, pathophysiology, clinical presentation, and management of PAD.

Abstract
Background: Disabling peripheral arterial disease (PAD) of femoropopliteal segment is usually treated with percutaneous balloon dilatation, and when this is not successful, stent is placed. Long-term patency of stent is often compromised due to in-stent restenosis (ISR). We aimed to identify factors associated with bailout stenting, and to recognise risk factors for ISR in procedures without paclitaxel application. Patients and methods: We analysed 592 consecutive successful femoropopliteal interventions performed in patients with either disabling intermittent claudication or chronic critical limb ischemia (CLI). In patients with stent implantation, clinical and ultrasound (US) examination were performed one year after the intervention to establish the presence of ISR, defined as >50% stenosis on US imaging. Results: Bailout stenting was required in 133 (22.5%) procedures. Patients with stent placement were younger (70±10 vs 72±11 years, p=0.007) and less often presented with CLI (29.3% vs 40.5%, p=0.019). They more often reported smoking (63.2% vs 49.2%, p=0.005), less often had diabetes mellitus (35.3% vs 47.5%, p=0.013) and arterial hypertension (82.0% vs 90.8%; p=0.004). Stenting was also dependent on lesion complexity (TASC II C>B>A; p<0.001). Subgroup analysis of 110 procedures with bare metal stent (BMS) placement performed in 107 patients revealed ISR in 46.4% of stents, in half of cases it was symptomatic. Neither clinical nor lesion characteristics proved to differ between the group of procedures with ISR and group of procedures without ISR. Conclusions: Factors associated with bailout stenting were age, diabetes mellitus, arterial hypertension, smoking, clinical picture of PAD and complexity of treated lesions. We did not find any risk factors influencing development of ISR in BMS.

Abstract
INTRODUCTION Several factors related to lesion characteristics and endovascular therapy (EVT) procedures have been reported to affect primary patency after EVT. However, it is unknown why these factors were associated with primary patency. We hypothesized patency failure was related to poor blood flow in affected arteries. METHODS This retrospective study included 131 consecutive patients who had received EVT with bare metal stents for peripheral artery disease caused by femoropopliteal artery lesions. Based on the tertile post-EVT flow velocity of the superficial femoral artery (SFA), patients were divided into high (n = 43), middle (n = 44), and low (n = 44) flow velocity groups. Flow velocity was measured using the frame count method. We measured incidence of major adverse limb events (MALE), composed of target lesion revascularization (TLR), non-TLR, and major amputation. RESULTS At a median follow-up period of 22.7 months, MALE had occurred in 7 (16.3%), 10 (22.7%), and 29 (65.9%) of patients from the high, middle, and low SFA flow velocity groups, respectively (p < 0.001). Kaplan-Meier analysis showed incidence of MALE was significantly higher in the patients of low SFA flow velocity (log-rank test χ2 = 38.8, p < 0.001). Multivariate analysis found low SFA flow velocity to be an independent predictor for MALE (hazard ratio: 4.42; 95% CI: 2.27 to 8.60; p < 0.001) as was ankle-brachial index. CONCLUSION Post-EVT SFA flow velocity for femoropopliteal artery lesions treated with bare metal stents is an independent predictor of limb patency. The frame count method for assessing arterial flow velocity is convenient and has potential for wide applications in EVT.

Abstract
PURPOSE This study investigated the 1-year clinical outcomes of directional atherectomy combined with drug-coated balloon (DA + DCB) in femoropopliteal artery disease (FPAD) from real-world experience. MATERIALS AND METHODS A retrospective study was conducted of patients treated between July 2016 and June 2019 using DA + DCB for FPAD. Patients' demographics, comorbidities, clinical characteristics and outcomes, and angiography and duplex ultrasound findings were analyzed. The 6-month and 1-year primary patency, primary assisted patency, secondary patency, and freedom from clinically-driven target lesion revascularization (CD-TLR) were evaluated. Univariate and multivariate analyses were performed to identify risk factors of primary patency loss or CD-TLR. RESULTS Seventy-nine consecutive patients (83 lesions, mean age 70.9 years, 52 men) were included. Twenty-seven limbs had lifestyle-limiting claudication and 56 limbs had critical limb ischemia. There were 73 and 10 limbs with de novo lesion and in-stent restenosis, respectively. The mean lesion length of all the patients was 22.1 cm. The mean length of chronic total occlusions (CTOs) was 8.3 cm. Severe calcification was found in 32.5% cases. The 1-year primary patency rate was 80.8% and freedom from CD-TLR was 92.2%. The bailout stenting rate was 2.4%. Patients with CTO >10 cm had significantly lower 1-year primary patency rate and freedom from CD-TLR than did patients with CTO ≤10 cm. Total length of CTO (stratified as ≤5 cm, 5-10 cm, >10 cm) was identified as an independent risk factor of 1-year primary patency loss and CD-TLR. CONCLUSION DA + DCB appears to be a safe and effective endovascular therapy to treat FPAD in real-world clinical practice, with a promising 1-year patency rate with a low rate of bailout stenting.

Abstract
The assessment of local blood flow patterns in patients with peripheral arterial disease is clinically relevant, since these patterns are related to atherosclerotic disease progression and loss of patency in stents placed in peripheral arteries, through mechanisms such as recirculating flow and low wall shear stress (WSS). However, imaging of vascular flow in these patients is technically challenging due to the often complex flow patterns that occur near atherosclerotic lesions. While several flow quantification techniques have been developed that could improve the outcomes of vascular interventions, accurate 2D or 3D blood flow quantification is not yet used in clinical practice. This article provides an overview of several important topics that concern the quantification of blood flow in patients with peripheral arterial disease. The hemodynamic mechanisms involved in the development of atherosclerosis and the current clinical practice in the diagnosis of this disease are discussed, showing the unmet need for improved and validated flow quantification techniques in daily clinical practice. This discussion is followed by a showcase of state-of-the-art blood flow quantification techniques and how these could be used before, during and after treatment of stenotic lesions to improve clinical outcomes. These techniques include novel ultrasound-based methods, Phase-Contrast Magnetic Resonance Imaging (PC-MRI) and Computational Fluid Dynamics (CFD). The last section discusses future perspectives, with advanced (hybrid) imaging techniques and artificial intelligence, including the implementation of these techniques in clinical practice.

Differentiating total from subtotal arterial occlusion in lower extremities by using reverse attenuation gradient sign in CT angiography. Eur Radiol 2021; 31:8335-8341. [PMID: 33890150 DOI: 10.1007/s00330-021-07929-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2020] [Revised: 02/07/2021] [Accepted: 03/23/2021] [Indexed: 12/01/2022]
Abstract
OBJECTIVES To investigate the use of reverse attenuation gradient sign (RAGS) in CT angiography (CTA) to differentiate total from subtotal occlusion in lower extremities which poses different challenges for the procedure and carries different prognoses. METHODS Eighty patients with 91 lesions in the lower extremities were divided into total occlusion (TO) group and subtotal occlusion (SO) group confirmed by digital subtraction angiography. The CT numbers of vascular lumen at the end of lesion (proximal, P) and at the first entrance (distal, D) of the lateral branch were measured and their difference (CT(PD) = CT(P) - CT(D)) of each lesion was calculated. The CT number gradient (G(DP) = 2 * CT(PD)/[CT(P) + CT(D)]) was calculated by dividing the CT number difference by the average CT number of the two points. The existence of RAGS where the CT number at the distal point is higher than that at the proximal point (CT(PD) and G(PD) < 0) was determined and the diagnostic efficacy of using RAGS in CTA for differentiating total from subtotal occlusive lesions in lower extremities was calculated. RESULTS The SO group had higher CT numbers than the TO group (p < 0.001). More importantly, the SO group had positive CT number gradient (G(PD) > 0), while the gradient was negative (G(PD) < 0) in the TO group. The specificity and sensitivity of using RAGS (G(PD) < 0) in images for diagnosing TO of lower extremity were 97.6% and 92.0%, respectively, and 87.8% and 88.0% using the standard CTA images. CONCLUSION The use of RAGS in CTA images has high diagnostic accuracy to differentiate TO from SO in lower extremities. KEY POINTS • Total occlusions often exhibit higher CT number at distal point than at proximal point to the occlusion. • The reverse attenuation gradient sign (RAGS) may be determined using the CT number measurements between the proximal and distal points after occlusion. • RAGS can be used to improve the diagnostic efficiency in CTA to differentiate between total and subtotal occlusions of lower extremity arteries.

Abstract
OBJECTIVE Covered stents (CS) to treat superficial femoral artery (SFA) occlusive disease have become more common. However, concerns about patients presenting with acute limb ischemia (ALI) after failure due to coverage of important collaterals have been raised. Herein, we determine if CS are associated with ALI after failure. METHODS Vascular Quality Initiative peripheral vascular intervention and infrainguinal bypass datasets were queried from 2010 to 2020 for patients who underwent SFA stenting with a bare metal stent (BMS) or CS and who also had a subsequent ipsilateral SFA endovascular reintervention or bypass recorded in the Vascular Quality Initiative. The initial SFA stenting procedure will be referred to as the index procedure and the subsequent procedure will be referred to as the reintervention. Patients with aneurysmal pathology, prior infrainguinal bypass, and ALI at the index procedure were excluded. Patients with pre-index inflow/outflow procedures were not excluded. The primary outcome was ALI at reintervention. Other outcomes included higher degree of ischemia (claudication vs rest pain vs tissue loss vs ALI) and reoperative factors. Predictors of the primary outcome were determined with multivariable logistic regression. The index treatment length and pre-index ankle-brachial index were forced into the model. RESULTS There were 3721 patients: 3338 with index BMS, 383 with index CS. The mean patients age was 66.3 ± 11.0 years and 59.2% were male. Baseline covariates were similar between the groups; during the index procedure, more patients with BMS underwent plain balloon angioplasty (68.7% vs 62.1%; P = .001) and had shorter total index treatment length (median, 15.0 cm [interquartile range, 10.0-25.0 cm] vs 20.0 cm [interquartile range, 12.0-30.0 cm]; P < .001). At reintervention, ALI was the presenting symptom for 12.0% of the CS cohort vs 6.3% of the BMS cohort (P < .001). More patients with an index CS underwent major amputation at the time of reintervention (2.6% vs 1.0%; P = .006). Reinterventions for the patients with a CS more often used bypass, pharmacologic thrombolysis, and mechanical thrombolysis. CS at the index procedure was a predictor of ALI at reintervention (odds ratio, 1.87; 95% confidence interval, 1.31-2.65; P = .001) while controlling for age, time difference between procedures, body mass index, chronic obstructive pulmonary disorder, preoperative anticoagulation and antiplatelet, prior carotid intervention and major amputation, index procedure fluoroscopy time and treatment length, and pre-index ankle-brachial index. CONCLUSIONS In patients undergoing reintervention for failed SFA stents, CS are more likely to present with ALI than those with failed SFA BMS.

Society for Vascular Surgery femoral runoff score is associated with limb-based patency after aortofemoral bypass. J Vasc Surg 2021; 74:124-133.e3. [PMID: 33548431 DOI: 10.1016/j.jvs.2020.12.084] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2020] [Accepted: 12/12/2020] [Indexed: 12/27/2022]
Abstract
OBJECTIVE Despite advancements, aortofemoral bypass (AFB) remains the most durable option for aortoiliac occlusive disease. Although runoff has been shown to be associated with AFB patency, the association of the Society for Vascular Surgery (SVS) thigh runoff scoring system with patency has not been assessed. The aim of the present study was to evaluate the association between the SVS runoff scoring system and limb-based primary patency after AFB. METHODS Institutional data for patients undergoing AFB with preoperative runoff imaging available from 2000 to 2017 were queried. Runoff scores were assigned according to the presence of occlusive disease in the superficial femoral artery and profunda femoris artery (minimum, 1; maximum, 10) as described by the 1997 SVS reporting standards for lower extremity ischemia. Limb-based patency was the primary endpoint. Kaplan-Meier analysis was used to compare the long-term limb-based patency and freedom from reintervention between limbs with runoff scores ≥6 and those with runoff scores <6. Propensity score-weighted Cox proportional hazards modeling was used to evaluate the association between a runoff score of ≥6 and primary patency loss, controlling for other factors associated with primary patency. RESULTS In 161 patients, 316 limbs had undergone revascularization. The mean patient age was 66.7 ± 11.3 years, and 51.6% were women. Most limbs had undergone revascularization for claudication (56.5%). Most (89.4%) had TransAtlantic InterSociety Consensus class D lesions, 27.3% had required suprarenal or higher clamping, and 11.2% had undergone concomitant mesenteric intervention. A femoral outflow adjunct and concurrent lower extremity bypass was required in 41.8% and 2.9% of limbs, respectively. Those with a runoff score of ≥6 had experienced greater rates of 30-day myocardial infarction (11% vs 1%; P = .005), respiratory failure (11% vs 1%; P = .005), and mortality (8% vs 0%; P ≤ .006). The median follow-up period was 4.0 years (interquartile range, 6.5 years). The 1-, 3-, and 5-year primary patency was 94.6% (95% confidence interval [CI], 91.9%-97.3%), 89.2% (95% CI, 85.4%-93.2%), and 81.4% (95% CI, 76.0%-87.1%), respectively. The 5-year primary-assisted patency, secondary patency, and freedom from reintervention were 84.9% (95% CI, 79.7%-90.5%), 91.7% (95% CI, 87.3%-96.3%), and 83.3% (95% CI, 78.3%-88.7%), respectively. Patients with a runoff score of ≥6 had lower primary (log-rank P < .01), primary-assisted (P < .01), and secondary patency (P = .01). The factors associated with the loss of primary patency included a high runoff score (runoff score of ≥6: hazard ratio [HR], 4.1; 95% CI, 2.1-8.0; P < .01), simultaneous mesenteric endarterectomy (HR, 13.5; 95% CI, 1.9-97.8; P = .01), and chronic kidney disease (HR, 4.6; 95% CI, 1.5-14.6; P = .01). Increasing age (HR, 0.94 per year; 95% CI, 0.91-0.97; P < .01) and hyperlipidemia (HR, 0.44; 95% CI, 0.23-0.85; P = .01) were protective. CONCLUSIONS The SVS femoral runoff score is an important factor associated with long-term AFB limb patency. Scores of ≥6 portend for worse limb outcomes and a greater incidence of operative complications. The SVS score can be determined from preoperative axial imaging studies and serve as a guide in decision-making and operative planning.

Influence of Infrapopliteal Runoff Vessels on Primary Patency after Superficial Femoral Artery Angioplasty with Stenting in Patients with Claudication. Vasc Specialist Int 2020; 36:233-240. [PMID: 33293487 PMCID: PMC7790694 DOI: 10.5758/vsi.200056] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2020] [Revised: 10/04/2020] [Accepted: 10/28/2020] [Indexed: 11/20/2022] Open
Abstract
Purpose The number of infrapopliteal runoff vessels seems to be one of the factors influencing arterial patency in patients who had undergone superficial femoral artery (SFA) angioplasty with stenting. However, the effectiveness of infrapopliteal runoff vessels in predicting patency during SFA angioplasty remains unclear. This study aimed to determine whether the number and quality of infrapopliteal runoff vessels affect the primary patency after SFA angioplasty with stenting in patients with claudication. Methods Materials and This study reviewed a retrospective database of patients with claudication who underwent SFA angioplasty with stenting between March 2011 and December 2016. The preoperative computed tomography findings of all patients were reviewed to assess infrapopliteal runoff vessels. The Trans-Atlantic Inter-Society (TASC) II classification and modified Society for Vascular Surgery (SVS) runoff score were used for subsequent analysis. Kaplan–Meier survival curves were constructed, and Fisher’s exact and chi-square tests were used for data analysis. Results A total of 153 limbs of 122 patients (88.2% male, mean age: 69.1 years) underwent SFA angioplasty with stenting. The overall primary patency rates of TASC II A/B and C/D cases were 77.1% and 31.2%, respectively, at 36 months (P<0.001). The primary patency rates at 36 months using the modified SVS runoff scoring system were 64.6% and 49.8% for the good-to-compromised (≤9 points) and poor (≥10 points) runoff groups, respectively (P=0.011). Conclusion The modified SVS runoff scoring system is effective in predicting primary patency after SFA angioplasty with stenting in patients treated for claudication.

Abstract
OBJECTIVES The purpose of this study was to evaluate the results of combining superficial femoral artery endovascular therapy with distal bypass originating from the popliteal artery as a method of lower extremity revascularization in patients with chronic limb-threatening ischemia. METHODS The records of patients undergoing combined superficial femoral artery endovascular therapy with popliteal-to-distal bypass for chronic limb-threatening ischemia from January 2014 to April 2020 at a single institution were retrospectively reviewed. The patients' background, operative details, and long-term outcomes were analyzed. RESULTS Fifty-two popliteal-to-distal bypasses with superficial femoral artery endovascular therapy were performed in 49 patients (33 men; mean age, 76 ± 9 years; diabetes mellitus, 80%; end-stage renal disease with hemodialysis, 47%). The Trans-Atlantic Inter-Society Consensus II classification of superficial femoral artery-popliteal lesion was "A" in 8 (15%) patients, "B" in 14 (27%) patients, "C" in 24 (46%) patients, and "D" in 6 (12%) patients. The intervention for superficial femoral artery lesions was plain old balloon angioplasty in 4 patients, self-expandable nitinol stent in 15 patients, drug-coated balloon in 18 patients, drug-eluting stent in 4 patients, stent graft in 10 patients, and interwoven nitinol stent in 1 patient. Distal bypass originated from the above-knee popliteal artery in 9 (17%) limbs and the below-knee popliteal artery in 43 (83%) limbs. The most common outflow artery was the posterior tibial artery (44%). The mean follow-up period was 17 ± 17 months. The primary and secondary patency of the graft was 44% and 72%, respectively, at 1 year and 39% and 72%, respectively, at 3 years. Primary patency and freedom from clinical-driven target lesion revascularization of superficial femoral artery endovascular therapy lesions were 85% and 90%, respectively, at 1 year and 63% and 75%, respectively, at 3 years. Limb salvage was 97% at 1 year and 92% at 3 years. Wound healing was 67% at 6 months and 83% at 12 months. CONCLUSIONS Combined superficial femoral artery endovascular therapy with popliteal-to-distal bypass may be a promising approach for patients with chronic limb-threatening ischemia because of durable patency, acceptable wound healing, and good limb salvage.

Abstract
Abstract
Background
Though uncommon, complications of endovascular angioplasty and stenting may have devastating outcomes that can threaten limb and life. Adequate awareness of these complications will allow to achieve excellent clinical outcomes.
Results
Endovascular intervention was successful in treatment of most of distal SFA complications with limited use in flush ostial complications; residual stenosis ≥ 30%, flow-limiting dissection, perforation or rupture; 100% in group (2) vs 50% in group (1) but thrombosis; 75% of distal SFA lesions were treated endovascularly vs 40% of flush ostial lesions; X2 = 12.7, P = 0.02. Emergency surgery as a bailout was used for most ostial lesion complications: residual stenosis ≥ 30%, flow-limiting dissection, and perforation or rupture; 50% in group (1) vs 0% in group (2); X2 = 20.1, P = 0.01.
Conclusion
Bailout procedures are procedures used to save the limb or the patient. Evolving endovascular strategies embrace new technologies in an attempt to improve the safety and efficacy of revascularization procedures for lower extremity arterial occlusive disease.

Abstract
Objective To evaluate the impact of run-off vessels number on the outcomes of Supera stent (Abbott Vascular, Santa Clara, Calif, USA) for treatment of femoropopliteal occlusive disease. Methods We retrospectively evaluated the medical records of 188 consecutive patients (mean age 68.2 ± 9.6 years, 100 males) undergone angiography and woven mesh stent implantation in femoral or popliteal arteries or both arterial segments, in our institution between January 1 2014 and January 1 2018. Target lesion revascularization and major adverse limb events at 12-month were evaluated comparing patients with 1-, 2- or 3-run-off vessels in the foot. Results Interventional success was achieved in 100%. Stent implantation involved in the femoral site in 56 patients (30.3%), the femoropopliteal in 92 patients (48.9%) and the popliteal site in 40 patients (21.3%). A significant improvement of ankle-brachial index (0.29 ± 0.6 vs. 0.88 ± 0.3, P < 0.001) and Rutherford class (5.3 ± 0.8 vs. 0.7 ± 1.9, P < 0.01) were observed before discharge. The median follow-up duration was 12.3 months (inter quartile range: 11.0 to 13.9). During the follow-up period, 52 patients (27.6%) had clinical events. Primary patency at 12 months was 72.4%. The primary patency significantly increased when the runoff status. Comparing the number of events among patients with different number of run-off vessels, a significant difference (P < 0.001) was observed for patients having one (24.0%) and two run-off vessels (15.0%). Conclusions The outcomes of Supera stent in femoropopliteal occlusive disease depend strictly on the number of run-off vessels.

Abstract
BACKGROUND Endovascular intervention is commonly pursued as first-line management of symptomatic, long-segment superficial femoral artery (SFA) disease. The relative effectiveness and comparative long-term outcomes among bare metal stents (BMS), covered stents (CS), and drug-eluting stents (DES) for long-segment SFA lesions remain uncertain. METHODS A retrospective cohort study identified patients with symptomatic SFA lesions measuring at least 15 cm in length who successfully received an endovascular stent (BMS, CS, or DES). The outcomes were patency, patient presentation upon stent occlusion, amputation-free survival (AFS), and all-cause mortality. Proportional hazards regressions and a multinomial logistic regression model were used to control for significant confounders. RESULTS A total of 226 procedures were analyzed (BMS: 95 [42%]; CS: 74 [33%]; DES: 57 [25%]). There were no significant differences among the 3 stent types with respect to age, prevalence of either diabetes or end-stage renal disease, or smoking history. The median length of the SFA lesion varied across the cohorts (BMS: 28 cm [interquartile range, IQR 20-30]; CS: 26 cm [IQR 20-30]; DES: 20 cm [IQR 16-25]; P = 0.002). The unadjusted primary patency of BMS at 12, 24, and 48 month following index stent placement was 57%, 47%, and 44%, respectively. This is compared to 62%, 49%, and 42% for CS, and 81%, 66%, and 53% for DES, respectively (log-rank P = 0.044). In adjusted models, however, there were no significant differences in primary patency among the stent types. Compared to CS however, DES was associated with improved primary-assisted patency (hazard ratio [HR] for patency loss: 0.35, P = 0.008) and secondary patency (HR: 0.32, P = 0.011). Across the entire follow-up period, stent occlusions occurred in 38 (40%) BMS cases, 42 (57%) CS, and 11 (19%) DES (P < 0.001). Of these, acute limb ischemia (ALI) occurred in 2 (5%) BMS cases, 14 (33%) CS, and 1 (9%) DES (P = 0.010). After adjustment, the relative risk of presenting with ALI as opposed to claudication was 27 times greater among patients re-presenting with occluded CS compared to BMS (P = 0.020). There were no significant differences in AFS or all-cause mortality across the 3 cohorts. CONCLUSIONS For long-segment SFA lesions, DES is associated with improved primary-assisted and secondary patency over long-term follow-up. In the event of stent occlusion, CS is associated with an increased risk of ALI.

Abstract
OBJECTIVE To investigate the differences in risk factors and in-hospital outcomes for women undergoing percutaneous coronary intervention (PCI) and peripheral vascular intervention (PVI). BACKGROUND The clinical impact of coronary artery disease (CAD) and peripheral artery disease (PAD) is well characterized and is associated with high morbidity and mortality. There is lack of data comparing risk factors and in-hospital outcomes for PCI and PVI, particularly in women. METHODS Only female hospitalizations (age ≥ 18 years) who underwent PCI or PVI from 2005 to 2014 were identified using appropriate International Classification of Diseases-Ninth Revision, Clinical Modification codes from the National Inpatient Sample database. Charlson's Comorbidity Index (CCI) was selected as the primary endpoint of the study. Coprimary endpoint was the cost of hospitalizations associated with PCI or PVI. RESULTS Of the 2,461,328 female hospitalizations that were included, 85.6% (N = 2,105,236) underwent PCI and 14.4% (N = 356,092) received PVI. Compared to PCI, PVI hospitalizations were 3.2 years older (p < .001) and consisted of significantly more hospitalizations above 80 years of age (26.5% vs. 18.6%; p < .001). Hospitalizations with CCI ≥3 were significantly higher in the PVI cohort (29.1% vs. 24%; p < .001). CCI in women increased during the study period for both groups. PVI hospitalizations had a significantly longer length of stay (3 days vs. 2 days; p < .001) and cost of hospitalization ($23,610 vs. $20,571; p < .001), compared to PCI. Finally, the mean cost of hospitalizations increased during the study period for PCI and PVI. CONCLUSION Women hospitalized for PVI had a greater risk-profile and resource utilization as demonstrated by the longer length of stay and higher cost compared to PCI.

Abstract
A 78-year-old woman with a prior history of a right femoropopliteal bypass 5 years before and a coronary artery bypass graft 3 months before was admitted for a non-healing ulcer on her right foot. A computed tomography angiogram revealed occlusion of her superficial femoral artery (SFA) from its orifice to the anastomotic site of the bypass graft. The lesion was thought to consist of a partial atherosclerotic plaque with a large number of relatively fresh thrombi, referring to an angiogram of her lower extremity 3 months ago. We recanalized the occlusive SFA by Fogarty thrombectomy, and endovascular therapy preceded by direct SFA endarterectomy.

Abstract
Purpose: To report an alternative approach for rescue of an occluded aortofemoral bypass using the Gore Excluder Iliac Branch Endoprosthesis (IBE). Case Report: A 52-year-old man presented with acute right limb ischemia because of displaced and occluded iliac stents and was treated with aortofemoral bypass. On the third postoperative day, there was early bypass failure due to distal embolization from aortic thrombus. After fluoroscopy-guided balloon thrombectomy of the bypass, an endovascular bailout strategy was used. The Gore Excluder IBE was deployed below the renal arteries (with the external iliac limb opening in the surgical prosthesis and the gate opening within the aortic lumen). After antegrade catheterization of the gate, a Gore Viabahn endoprosthesis was inserted as the bridging endograft and deployed so that it landed just above the preimplanted aortoiliac kissing stents without overlapping them. Completion angiography showed technical success without complications; results were sustained at 1-year follow-up. Conclusion: The Gore Excluder IBE may represent a versatile solution for the rescue of complex cases when open surgery would be associated with a considerable risk. This off-label application of a well-recognized endovascular device is safe and feasible and may prove useful as a valuable alternative in properly selected patients.

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

Abstract
PURPOSE To investigate the effect of distal stenotic lesions on flow patterns near a covered endovascular reconstruction of the aortic bifurcation (CERAB) configuration used in the treatment of aortoiliac occlusive disease. METHOD Laser particle image velocimetry measurements were performed using in vitro models of the aortic bifurcation with and without a CERAB configuration in place. A hemodynamically nonsignificant stenosis (ΔP: 9 mm Hg), a hemodynamically significant (ΔP: 26 mm Hg) stenosis, and a total occlusion were simulated in the left iliac arteries. Velocity fields and time-averaged wall shear stress (TAWSS) were calculated. RESULTS Hemodynamically significant distal lesions did not influence the inflow patterns or TAWSS (0.5-0.6 Pa) in either model. However, hemodynamically significant distal stenotic lesions caused a 2-fold decrease in peak outflow velocities (control: 106 vs 56 cm/s, CERAB: 96 vs 54 cm/s) and a 3-fold decrease in TAWSS (control: 1.34 vs 0.44 Pa, CERAB: 0.75 vs 0.21 Pa). There was a 2-fold decrease in wall shear stress in the CERAB outflow compared with the control, independent of lesion severity. CONCLUSION In the CERAB technique, adequate distal runoff is identified as an important parameter to ensure patency. This in vitro study showed that distal stenotic lesions influence aortic bifurcation outflow patterns and TAWSS more extensively in the CERAB configuration. Distal stenotic lesions could therefore increase the risk of disease progression and loss of stent patency. In vivo studies are necessary to confirm these observations.

Abstract
PURPOSE To evaluate 2-year results of the Zilver PTX (Cook Medical, Bloomington, Indiana) drug-eluting stent (DES) for femoropopliteal peripheral artery disease (PAD) in patients with no continuous patent infrapopliteal runoff arteries compared with patients with ≥ 1 continuous patent runoff vessels. MATERIALS AND METHODS A retrospective analysis of patients with femoropopliteal PAD enrolled in the Zilver PTX Post-Market Surveillance Study in Japan was performed. There were no exclusion criteria. Outcomes, including freedom from target lesion revascularization (TLR), patency, and clinical benefit, for the no-runoff group (n = 54) were compared with the runoff group (n = 846). RESULTS The 2 groups were similar in terms of demographics, lesion characteristics, and comorbidities (P > .05). There was a higher incidence of critical limb ischemia in the no-runoff group compared with the runoff group (44.8% vs 19.7%; P < .01). There were 3 amputations (5.6%) in the no-runoff group versus 7 amputations (0.8%) in the runoff group (P = .02). At 2 years, freedom from TLR rates were 81.3% versus 83.8% (P = .87), patency rates were 68.4% versus 70.7% (P = .95), and clinical benefit rates were 73.7% versus 80.0% (P = .16) in the no-runoff versus runoff group, respectively. CONCLUSIONS Results in patients with no continuous patent tibial runoff were favorable through 2 years and similar to results for patients with ≥ 1 continuous patent runoff vessels, indicating that the Zilver PTX DES may be a valid treatment option for patients with these difficult-to-treat lesions.

Abstract
BACKGROUND Percutaneous endovascular therapy is becoming a primary option for managing femoropopliteal occlusive disease. The purpose of this study was to evaluate the mid-term results of endovascular treatment of femoropopliteal arterial disease. METHODS Femoropopliteal percutaneous transluminal angioplasty was performed on 162 consecutive limbs (160 patients) from January 2006 to January 2016. RESULTS In our study, 87.6% of patients had critical limb ischemia. Lesions were classified as Trans-Atlantic Inter-Society Consensus (TASC) A (43%), B (43%), C (7%), and D (7%). Femoropopliteal interventions included angioplasty only in 70 cases (43.2%), and the remaining 92 (56.8%) received at least one stent. Technical success was achieved in 98.7% of patients, with three deaths and a major morbidity rate of 15%. The actuarial primary patency at 12 and 36 month was 65.4% and 40.2%, respectively, 33 peripheral reinterventions were performed after femoropopliteal axis occlusion, resulting in an actuarial primary limb preservation rate of 94.4 at 12 months. Comparison between angioplasty only and the use of stent show no difference in primary patency (P=0.832) and limb salvage (P=0.67). Negative predictors of primary patency determined by univariate analysis included popliteal location (P<0.001) and TASC D (P<0.001). However, diabetes mellitus (P=0.001) and poor run off (P<0.001) were the principal predictive factors of limb loss. CONCLUSION Femoropopliteal angioplasty can be performed with a low morbidity and mortality. Intermediate primary patency is directly related to TASC classification and popliteal localization.

Abstract
In-stent restenosis is a pervasive challenge to the durability of stenting for the treatment of lower extremity ischemia. There is considerable controversy about the criteria for diagnosis, indications for treatment, and preferred algorithm for addressing in-stent restenosis. This evidence summary seeks to review existing information on strategies for the treatment of this difficult problem.

Abstract
Purpose Favorable long-term outcomes of the Zilver PTX drug-eluting stent (DES) in femoropopliteal lesions have been demonstrated. Chronic renal failure (CRF) has been shown to be a risk factor for restenosis and decreased limb salvage. The results of the DES in patients with CRF have not previously been reported. This study compares the results with the DES in patients with CRF and those without CRF. Methods This retrospective analysis from the Zilver PTX Japan Post-Market Surveillance Study included 321 patients with CRF and 584 patients without CRF. Outcomes included freedom from target lesion revascularization (TLR) and patency. Results Of the patients included in this subgroup analysis, 2-year data were available for 209 patients in the CRF group and 453 patients in the non-CRF group. The two groups were similar in terms of lesion length and the frequency of in-stent restenosis. Critical limb ischemia, severe calcification, and diabetes were more common in patients with CRF, whereas total occlusion was more common in patients without CRF. Freedom from TLR rates were 81.4 versus 84.9% (p = 0.24), and patency rates were 70.7 versus 70.3% (p = 0.95) in patients with and without CRF at 2 years, respectively. Conclusion This is the first comparative study of the DES in femoropopliteal artery lesions in patients with and without CRF. These results indicate that the DES placed in femoropopliteal artery lesions of CRF patients is safe and effective with similar patency and TLR rates to patients without CRF.

Abstract
Purpose The present study aimed to determine the safety and efficacy of a drug-coated balloon inflated within a thin-strut self-expanding bare-metal stent in patients with severe and complex femoropopliteal occlusive disease. Methods This prospective study used the Pulsar-self-expanding stent and Passeo-18 Lux drug-coated balloon in patients with severe and complex femoropopliteal occlusive disease. The primary endpoint was the 12-month primary patency, and the secondary endpoints included 24-month primary patency, assisted primary patency, secondary patency, and clinically associated target lesion revascularisation. Results The study included 44 patients (51 limbs). The mean age of the patients was 67.6 ± 10.2 years, with 73% men. Chronic limb severity was classified as Rutherford Category III in 41% of the patients, stage IV in 31%, and stage V in 27%. Lesions were predominantly Trans-Atlantic Inter-Society Consensus (TASC 2007) D (51%) and C (45%), with 32 (63%) chronic total occlusions. Procedural success was obtained in all cases. The mean lesion length was 200 ± 74.55 mm (95% CI = 167.09–208.01) with a mean number of stents per limb used of 1.57 ± 0.70 (95% CI = 1.37–1.76). Distal embolisation occurred in two patients. The primary patency rates at the 12- and 24-month follow-up were 94% (95% CI = 82.9–98.1) and 88% (95% CI = 75.7–94.5), respectively. The assisted primary was 94% (95% CI = 82.9–98.1) and secondary patency was 96% (95% CI = 85.2–99.0) at 24-month follow-up. The cumulative stent fracture rate at the 24-month follow-up was 10%. Freedom from clinically driven target lesion revascularisation was 94% (95% CI = 83–98%) at 12-month follow-up and 88% (95% CI = 76–94%) at 24-month follow-up, with two patients requiring a bypass graft. Conclusion Our novel approach involving the combination of a thin-strut bare-metal stent and a drug-coated balloon may be safe and effective, with sustainable and promising clinical outcomes up to 24 months after treatment.

Abstract
The superficial femoral artery is a complex artery subject to a unique set of biomechanical loading conditions in its course through the leg. Plain balloon angioplasty and balloon-expandable stents had unacceptably high rates of restenosis, necessitating target vessel revascularization. Nitinol alloy is well suited to provide the strength and flexibility needed of stents to withstand the external forces posed by the environment of the superficial femoral artery. Advances in stent technology with the addition of a slow-releasing antiproliferative agent and changes in scaffold design have shown promise in reducing the rates of stent fracture and in-stent restenosis.

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

Abstract
The treatment of femoropopliteal artery disease remains controversial, without clear guidelines specifying the indications for endovascular therapy (EVT). Accordingly, we retrospectively examined our experience of using EVT to treat femoropopliteal artery disease. A total of 91 limbs in 82 patients underwent EVT for the treatment of femoropopliteal artery disease. Percutaneous transluminal angioplasty alone was performed in 20 limbs, and additional stenting was performed in 71 limbs. The 1-year primary patency, primary-assisted patency, limb salvage, and survival rates were 76%, 88%, 96%, and 92%, respectively. Multivariate Cox analysis of primary patency showed that critical limb ischemia (CLI; hazard ratio [HR], 2.53; 95% confidence interval [CI], 1.08-5.33; P < .01) and TASC II C/D disease (HR, 2.70; 95% CI, 1.14-6.39; P < .05) were independent predictors of decreased primary patency. In conclusion, patients with CLI or extensive lesions have reduced patency after EVT for femoropopliteal artery disease.

[PMID: 26541966 DOI: 10.1016/j.avsg.2015.07.039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2015] [Revised: 07/24/2015] [Accepted: 07/31/2015] [Indexed: 11/29/2022]
Abstract
BACKGROUND To analyze the clinical impact derived from endovascular treatment failure on patients with femoropopliteal occlusive disease (FPOD) regarding their preoperative clinical stage. METHODS Retrospective review for primary endovascular procedures for FPOD from 2008 to 2013. Primary end point included clinical deterioration defined as acute limb ischemia (ALI) or clinical worsening by, at least, one Rutherford's classification category, related to procedure's failure (restenosis >70% or occlusion). RESULTS Ninety procedures were analyzed in 85 patients, 87.8% operated due to critical limb ischemia. The lesion treated was classified as Trans-Atlantic Inter-Society Consensus (TASC)-A/B in 76.7%, with a mean length of 98.5 ± 54 mm. Covered stent graft (SG) was used in 31.1% of the cases. Median follow-up was 14.5 months and treatment failure occurred in 33.3% of cases (n = 30, 9 restenosis and 21 occlusions). Clinical worsening was assessed in 40% of treatment failures and 6 of 21 (28.6%) presented as ALI. Twenty-two major adverse limb events (MALEs) were recorded and 8 major amputations. Regarding the type of stent, more occlusions were recorded on patients treated with SG compared with bare metal stent (39.3% vs. 16%; P = 0.02). However, no differences were found between groups regarding clinical worsening attributable to treatment failure (HR, 1.33; CI 95%, 0.5-3.5; P = 0.5). On multivariate analysis, TASC-C/D lesions (HR, 5.5; CI 95%, 2.3-13.3; P < 0.001) and female sex (HR, 4.9; CI 95%, 1.9-12.5; P = 0.001) behaved as significant predictors for failure and dual-antiplatelet therapy as a protective factor (HR, 0.3; CI 95%, 0.3-0.13; P = 0.03). No predictors were obtained regarding clinical worsening and occurrence of MALEs in our series. CONCLUSIONS Patients with failure of endovascular procedures on FPOD appeared with clinical worsening in a no negligible number of cases in our sample regarding their preoperative clinical situation. Thus, we believe that endovascular treatment should be carefully deliberated.

Abstract
Purpose: To investigate the 5-year outcome of patients treated with self-expanding covered stents for superficial femoral artery (SFA) occlusive disease and identify parameters that could predict loss of primary patency. Methods: In a dual-center study, 315 consecutive patients (mean age 69.0±10.1 years; 232 men) treated for SFA occlusive disease in 334 limbs with Viabahn self-expanding covered stents between 2001 and 2014 were retrospectively analyzed. Mean lesion length was 11.7±8.8 cm, and half of the lesions were classified as TASC II C/D. Five-year patency rates were calculated, and Cox regression analyses were performed to assess potential factors affecting patency. Results: All-cause mortality at 5 years was 14.1%. Primary patency rates at 1, 3, and 5 years were 72.2%, 51.8%, and 47.6%, respectively, with secondary patency rates of 86.2%, 78.7%, and 77.5%. Parameters predicting loss of primary patency in a univariate analysis were covered stent diameter (p=0.001), the number of covered stents per lesion (p=0.015), and TASC II D classification (p=0.007). Covered stent diameter was the only parameter predicting loss of primary patency in the multivariate regression analysis (p=0.001), with 7-mm covered stents having superior performance. Conclusion: Five-year patency rates of self-expanding covered stents inserted for SFA occlusive disease are within an acceptable range. Covered stent diameter is the most relevant factor in predicting loss of primary patency, and thus, an adequate diameter of the distal landing site seems to be among the most important factors in the decision-making process. In smaller vessels, one should not use covered stents but venous conduits, as oversizing may be detrimental.

Anatomic runoff score predicts cardiovascular outcomes in patients with lower extremity peripheral artery disease undergoing revascularization. Am Heart J 2015; 170:400-8.

Abstract
BACKGROUND Although the presence, extent, and severity of obstruction in patients with lower extremity peripheral artery disease (LE PAD) affect their functional status, quality of life, and treatment, it is not known if these factors are associated with future cardiovascular events. We empirically created an anatomic runoff score (ARS) to approximate the burden of LE PAD and determined its association with clinical outcomes. METHODS We evaluated all patients with LE PAD and bilateral angiography undergoing revascularization in a community-based clinical study. Primary clinical outcomes of interest were (1) a composite of all-cause death, myocardial infarction (MI), and stroke and (2) amputation-free survival. Cox proportional hazards models were created to identify predictors of clinical outcomes. RESULTS We evaluated 908 patients undergoing angiography, and a total of 260 (28.0%) patients reached the composite end point (45 MI, 63 stroke, and 152 death) during the study period. Anatomic runoff score ranged from 0 to 15 (mean 4.7; SD 2.5) with higher scores indicating a higher burden of disease, and an optimal cutpoint analysis classified patients into low ARS (<5) and high ARS (≥5). The unadjusted rates of the primary composite end point and amputation-free survival were nearly 2-fold higher in patients with a high ARS when compared with patients with a low ARS. The most significant predictors of the composite end point (death/MI/stroke) were age (δ 10 years; hazard ratio [HR] 1.53; CI 1.32-1.78; P < .001), diabetes mellitus (HR 1.65; CI 1.26-2.18; P < .001), glomerular filtration rate <30 (HR 2.23; CI 1.44-3.44; P < .001), statin use (HR 0.66; CI 0.48-0.88; P < .001), and ARS (δ 2 points; HR 1.21; CI 1.08-1.35; P < .001). CONCLUSIONS After adjustment for clinical factors, the LE PAD ARS was an independent predictor of future cardiovascular morbidity and mortality in a broadly representative patient population undergoing revascularization for symptomatic PAD. A clinically useful anatomic scoring system, if validated, may assist clinicians in risk stratification during the course of clinical decision making.

Abstract
Peripheral arterial disease (PAD) continues to grow in global prevalence and consumes an increasing amount of resources in the United States health care system. Overall rates of intervention for PAD have been rising steadily in recent years. Changing demographics, evolution of technologies, and an expanding database of outcomes studies are primary forces influencing clinical decision making in PAD. The management of PAD is multidisciplinary, involving primary care physicians and vascular specialists with varying expertise in diagnostic and treatment modalities. PAD represents a broad spectrum of disease from asymptomatic through severe limb ischemia. The Society for Vascular Surgery Lower Extremity Practice Guidelines committee reviewed the evidence supporting clinical care in the treatment of asymptomatic PAD and intermittent claudication (IC). The committee made specific practice recommendations using the GRADE (Grades of Recommendation Assessment, Development and Evaluation) system. There are limited Level I data available for many of the critical questions in the field, demonstrating the urgent need for comparative effectiveness research in PAD. Emphasis is placed on risk factor modification, medical therapies, and broader use of exercise programs to improve cardiovascular health and functional performance. Screening for PAD appears of unproven benefit at present. Revascularization for IC is an appropriate therapy for selected patients with disabling symptoms, after a careful risk-benefit analysis. Treatment should be individualized based on comorbid conditions, degree of functional impairment, and anatomic factors. Invasive treatments for IC should provide predictable functional improvements with reasonable durability. A minimum threshold of a >50% likelihood of sustained efficacy for at least 2 years is suggested as a benchmark. Anatomic patency (freedom from restenosis) is considered a prerequisite for sustained efficacy of revascularization in IC. Endovascular approaches are favored for most candidates with aortoiliac disease and for selected patients with femoropopliteal disease in whom anatomic durability is expected to meet this minimum threshold. Conversely, caution is warranted in the use of interventions for IC in anatomic settings where durability is limited (extensive calcification, small-caliber arteries, diffuse infrainguinal disease, poor runoff). Surgical bypass may be a preferred strategy in good-risk patients with these disease patterns or in those with prior endovascular failures. Common femoral artery disease should be treated surgically, and saphenous vein is the preferred conduit for infrainguinal bypass grafting. Patients who undergo invasive treatments for IC should be monitored regularly in a surveillance program to record subjective improvements, assess risk factors, optimize compliance with cardioprotective medications, and monitor hemodynamic and patency status.

Abstract
This article is a review of the evidence regarding the management of patients with critical limb ischemia. The aim of the study is to discuss the definition, incidence, and clinical importance of critical limb ischemia, as well as the aims of treatment in terms of quality of life and limb salvage. Endovascular and surgical treatments should not be viewed as competing therapies. In fact, these are complementary techniques each with strengths and weaknesses. The authors will propose a strategy based on the available evidence for deciding the optimal approach to management of patients with critical limb ischemia.

Abstract
BACKGROUND The aims of this study were to determine the effect of failed prior endovascular treatment (EV) on early and midterm outcomes of subsequent lower extremity open surgical (OS) bypass. METHODS Patients undergoing infrainguinal bypass for critical limb ischemia (CLI) from January 2008 to December 2011 were retrospectively reviewed. The results after first-line bypass and bypass after failure of EV treatment were compared. A total of 213 patients (65.25% men; average age, 73.30 years) underwent bypass. OS patients were then divided into 2 groups: group 1 consisted of 138 patients who underwent primary OS for CLI without prior EV (control group) and group 2 consisted of 75 patients who had OS after a failed attempt at elective EV for peripheral vascular disease. Of the 213 bypass performed, 34% had a prior infrainguinal failed EV. The primary study end points were early and 1-year major amputations and graft occlusion. The secondary outcomes included early and 1-year mortality and the level of distal revascularization. RESULTS Secondary patency and limb salvage rates were significantly better in group 1 up to 1 year (99% vs. 86%; P < 0.001 at 1 month and 95% vs. 76%, P < 0.05 at 12 months, respectively). CONCLUSIONS Previous failed EV should be predictive of poor outcome in patients undergoing distal OS for CLI.

Abstract
Objective To compare outcomes of hybrid (combined surgical and endovascular) procedures (HYBRID) with open surgical reconstructions (OPEN) in patients with multilevel infrainguinal artery occlusive diseases. Design Case series study with retrospective analysis of prospectively collected nonrandomized data. Methods Between 2008 and 2012, 64 patients underwent OPEN and 43 underwent HYBRID. Patient characteristics, technique success, clinical improvement, and procedure-related morbidity were reviewed and compared. Patency rates and limb salvages were analyzed and compared using Kaplan–Meier life tables. Cox regression analyses were used to assess the influence of various risk factors on primary patency. Results HYBRID patients were older and presented with worse New York Heart Association function compared with OPEN patients. The increase in the ankle-brachial index and improvement of Ruthford category after procedures were equivalent between two groups, but HYBRID patients had shorter hospital length of stay (7.6±12.0 versus 15.5±17.3; P= 0.018) and less overall perioperative morbidity (12% versus 28%; P=0.042) compared with OPEN patients. No statistically significant difference in 36-month primary (47.1%±7.1% versus 50.1%±9.4%; P=0.418), assisted primary (57.0%±7.9% versus 62.4%±9.2%; P=0.517), or secondary (82.0%±6.8% versus 83.1%±7.3%; P=0.445) patency was seen between the two groups. Limb salvage rates of HYBRID vs OPEN at 3 years were similar (76.3%±9.3% versus 80.4%±8.2%; P=0.579). Critical limb ischemia was a negative predictor of long-term patency of patients in both the HYBRID and OPEN groups (P=0.012 and P<0.001, respectively), and the presence of diabetes and renal insufficiency were another two independent predictors of decreased primary patency for HYBRID (P=0.017 and P=0.019, respectively). Conclusion Multilevel infrainguinal artery occlusive diseases could be treated by hybrid procedure, with shorter hospitalization, less perioperative morbidity, and similar early- and long-term efficacy compared with open revascularization. A hybrid procedure should be considered for patients with high surgical risk, but critical limb ischemia, diabetes, and renal insufficiency could compromise its long-term patency.

Abstract
Treatment of the femoropopliteal (FP) artery remains a challenge to the endovascular specialist. Long-term patency is low with a high rate of target lesion revascularization. The true patency rate varies considerably between studies partly because there is a lack of uniform performance criteria and reporting standards in peripheral arterial interventions. Literature review supports three principles that emerge as important components of an optimal strategy in treating the FP artery: (1) improving vessel compliance and subsequently less dissections and bailout stenting, (2) reducing smooth muscle cell proliferation, and (3) protecting outflow vessels from distal embolization. In this overview, we examine current data that support the validity of this strategy.

Abstract
PURPOSE Infrainguinalfemoropopliteal bypass (IFPB) is recommended to peripheral arterial disease (PAD) with a long occlusion of the superficial femoral artery (SFA). The aims of our study were to determine the patency of graft materials, and identify the risk factors of graft failure. METHODS From January 1995 to April 2011, we had performed 380 IFPBs in 351 patients, including 302 femoro-above the knee (AK) bypasses and 78 femoro-below the knee (BK) bypasses. We compare age, sex, severity of ischemia between polytetra-uoroethylene (PTFE) graft and saphenous vein (SV) graft, and evaluate patency rate rates of the two groups. RESULTS The primary patency rates at 5 years for SV (n = 76 limbs) and PTFE grafts (n = 226 limbs) in AK were 85.2% and 64.5% (log rank = 0.03), and the secondary patency rates at 5 years for SV and PTFE grafts in AK were 88.2% and 79.0% (log rank = 0.13). The primary patency rates at 5 years for SV (n = 50 limbs) and PTFE grafts (n = 28 limbs) in BK were 63.2% and 40.0% (log rank = 0.08), and the secondary patency rates at 5 years for SV and PTFE grafts in BK were 71.6% and 55.5% (log rank = 0.18). CONCLUSION There was no statistical significant difference in secondary patency rates between SV and PTFE in IFPB. PTFE grafts as SV grafts can be a good alternative bypass material in IFPB instead of SV grafts.

Abstract
OBJECTIVE Current clinical classification of superficial femoral artery (SFA) occlusions as defined by TASC II guidelines is limited to length and calcifications analysis on 2D angiograms, while state-of-the-art cross-sectional imaging like computed tomography angiography (CTA) and magnetic resonance angiography (MRA) provides much more detailed anatomical information than traditional invasive angiography: quantitative morphological analysis of these advanced imaging techniques could therefore be the basis of a refined classification. METHODS AND RESULTS Forty-six patients (65% men, 68±11.6 years) that underwent lower limb CTA were retrospectively included, totalizing 60 SFA occlusions. Lesions were classified as TASC II stage A in 3% of cases, stage B in 20%, stage C in 2% and stage D in 75%. For each pathological artery, curved multiplanar reconstructions following the occluded SFA course were used to measure the total length and the mean diameter of the occluded segment. Color-coded map provided an accurate estimation of calcifications' volume. Thirty-nine percent of the occlusions were total. Mean occluded segment length was 219±107 mm (range, 14-530 mm); mean occluded segment diameter was 6.1±1.6 mm (range, 3.4-10 mm); mean calcifications' volume in the occluded segment was 1,265±1,893 mm(3) (range, 0-8,815 mm(3)), corresponding to a percentage of 17.4%±20% (range, 0-88.7%). Shrinked occluded occlusions were defined by a mean diameter under 5 mm and heavily calcified occlusions by a mean percentage of calcifications above 4%. Use of these thresholds allowed the distinction of four groups of patients: heavily calcified occlusions with preserved caliber (56%), non-calcified occlusions with preserved caliber (19%), non-calcified occlusions with small caliber (15%) and heavily calcified occlusions with small caliber (10%). CONCLUSIONS SFA OCCLUSIONS ARE DISPARATE: this simple morphological study points out TASC II classification weaknesses for SFA occlusions, as quantitative cross-sectional imaging analysis with measurement of mean occluded diameter and percentage of calcifications can refine it. This could be particularly useful in the management of TASC II type D lesions, for which new endovascular revascularization techniques are arising, and where a CTA or MRA-based morphological classification could provide support in choosing between them.

Abstract
PURPOSE Describe outcomes after endovascular intervention of TransAtlantic Inter-Society Consensus C and D femoro-popliteal disease. MATERIALS AND METHODS Retrospective cohort study. Patient demographics, ankle-brachial indices, and lesion details were analyzed from a prospectively maintained database. In all, 980 limbs treated with percutaneous transluminal angioplasty±stenting of the femoro-popliteal segment between 2005 and 2012 were reviewed. Seventy-six patients representing 83 limbs with de novo TransAtlantic Inter-Society Consensus C and D lesions measuring ≥15 cm continuously were identified (mean age 71.3±12.1 years, 62% male). RESULTS Twenty-five (30.1%) limbs were treated for severe claudication and 58 (69.9%) for critical limb ischemia. The mean pre-procedural ankle-brachial index was 0.47±0.19. The mean lesion length was 22.9±4.82 cm. Seventy patients representing 77 limbs were available for a mean follow-up length of 19.5 months (range 0-79). The mean post-procedural ankle-brachial index was 0.71±0.28. Primary, assisted-primary, and secondary patency rates were 68.1%, 72.7%, and 83.3% at 6 months, 55.3%, 63.6%, and 58.3% at 12 months, and 38.2%, unavailable, and 10.4% at 24 months, respectively. CONCLUSIONS Angioplasty-first strategy for TransAtlantic Inter-Society Consensus C and D lesions of the femoro-popliteal artery can be safely performed. However, patency drastically decreases after 12 months suggesting further improvements are required to achieve longer-term clinical benefit.

Abstract
Background Women have high rates of peripheral artery disease (PAD) despite fewer cardiovascular disease (CVD) risk factors, compared to men. We sought to determine the gender‐specific prevalence of low ankle brachial index (ABI) and the relationship to C‐reactive protein (CRP) levels and CVD risk factors in the Life Line Screening population. Methods and Results Between April 2005 and August 2011, 133 750 women and 71 996 men had ABI and CRP measured at a Life Line Screening Center. Women were slightly older than men, whereas men were more likely to be current smokers, have diabetes mellitus (DM), and coronary artery disease (CAD) (P<0.001 for each). Women were more likely to have ABI≤1.0, compared to men (26.6% versus 14.4%, respectively; P<0.001), as well as ABI≤0.9 (4.1% women versus 2.6% men; P<0.001). Women had higher median CRP levels (1.94 mg/L; interquartile range [IQR], 0.89, 4.44 mg/L), compared to men (1.35 mg/L; IQR, 0.73, 2.80 mg/L; P<0.001). Men and women shared similar risk factors for ABI≤0.9, including older age, black race, smoking, DM, hypertension, hypercholesterolemia, CAD, and elevated CRP levels. In an adjusted model, there were significant interactions between gender and age (P<0.001), CRP (P<0.001), CAD (P=0.03), and DM (P=0.06) with ABI as the outcome. The associations between age, CRP, CAD, and DM with ABI≤0.9 were stronger in men than in women. Conclusions Women participating in the Life Line Screening had higher CRP levels and a higher prevalence of PAD, compared to men. Neither higher CRP levels nor conventional CVD risk factors explained the excess prevalence of PAD in women.

Hiramori S, Soga Y, Tomoi Y, Tosaka A. Impact of runoff grade after endovascular therapy for femoropopliteal lesions. J Vasc Surg 2013; 59:720-7. [PMID: 24377941 DOI: 10.1016/j.jvs.2013.09.053] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2013] [Revised: 09/20/2013] [Accepted: 09/24/2013] [Indexed: 11/17/2022]
Abstract
BACKGROUND We conceived a new method, runoff grade, to evaluate runoff after endovascular therapy (EVT). We evaluated the validity of using runoff score based on angiographic findings. METHODS The subjects were 859 consecutive patients (males, 69%; mean age, 73.0 ± 9.0 years) who underwent EVT for de novo femoropopliteal lesions at Kokura Memorial Hospital. We evaluated the postprocedural tibial runoff, named it runoff grade, classified it into 0 through 2, and retrospectively assessed the relationship with the outcome of EVT. Primary, secondary, and assisted primary patency rates and freedom from major adverse limb events (MALE) were compared between runoff grades. RESULTS The mean follow-up period was 31 ± 25 months. The lesion length was 91.5 ± 83.0 mm. The rate of stent use was 52.0%. The primary patency rates at 1, 2, and 3 years were 68.1%, 59.1%, and 53.9%; the secondary patency rates were 90.9%, 88.1%, and 85.9%; the assisted primary patency rates were 79.4%, 72.6%, and 68.5%; and freedom from MALE was 72.5%, 64.8%, and 61.0%, respectively. The primary patency rates at 1, 2, and 3 years were significantly lower in the runoff grade 0 group than in the other groups (55.5% vs 66.7% and 75.6%; 35.8% vs 57.6% and 69.2%; 35.8% vs 53.3% and 60.9% for grade 0, 1, 2, respectively; log-rank, P < .0001). Secondary patency rate (78.5% vs 91.8% and 91.8%; 76.3% vs 88.6% and 89.9%; 72.8% vs 86.3% and 88.2%, respectively; P = .015), assisted primary patency rate (67.0% vs 78.5% and 85.1%; 56.9% vs 71.6% and 79.3%; 47.6% vs 68.0% and 74.8%; respectively, P = .0002), and freedom from MALE (60.8% vs 71.2% and 79.4%; 44.3% vs 64.0% and 72.6%; 36.6% vs 60.7% and 68.5%, respectively; P < .0001) were also similar. After adjustment for age, gender, diabetes, hemodialysis, critical limb ischemia, TransAtlantic Inter-Society Consenus II classification, and stent use, runoff grade was an independent predictor of primary patency. CONCLUSIONS Vessels with runoff grade 0 had significantly worse cumulative outcomes. Our results suggested that runoff grade seemed to play an important role to keep the primary patency.
