Abstract
Below-the-knee (BTK) pseudoaneurysms that occur after endovascular therapy (EVT) and result in delayed rupture have rarely been reported. In this report, we present a rare case of an 86-year-old man with chronic limb-threatening ischemia who developed delayed rupture of an idiopathic pseudoaneurysm of the peroneal artery (PA) following EVT. The PA chronic total occlusion (CTO) was successfully crossed using a guidewire via an antegrade approach, however, subintimal crossing was confirmed by intravascular ultrasound. Balloon angioplasty was then performed using an appropriately sized balloon, resulting in successful recanalization of the PA CTO with minor dissection and no complications. Postoperatively, the patient's condition was stable until he suddenly complained of right calf pain 10 days after EVT. Computed tomography revealed a rupture of the PA pseudoaneurysm. Urgent angiography revealed two pseudoaneurysms, one saccular and the other spindle-shaped. The ruptured saccular aneurysm was successfully excluded through coil embolization and stent graft placement. To the best of our knowledge, this is the first reported case of delayed rupture of a BTK pseudoaneurysm following EVT. Balloon angioplasty in the subintimal space can lead to the formation of a pseudoaneurysm and its delayed rupture.

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

Abstract
Introduction: Patients with peripheral artery disease (PAD) are at higher risk for all-cause mortality, driven by increased cardiovascular mortality rates. In this manuscript we review the literature on guideline-recommended therapies and discuss the major clinical considerations after endovascular therapy of PAD.Areas covered: Current guidelines recommend smoking cessation, aspirin, statin, and renin-angiotensin system inhibitors in order to reduce the risk of cardiovascular and limb-related adverse events. Nonetheless, studies have shown that patients with PAD are undertreated with these important medical therapies. Additionally, there is lack in evidence regarding the most optimal follow up imaging approach for early detection of disease recurrence and re-intervention among patients undergoing endovascular therapy for PAD. We also describe the benefits of supervised walking exercise for patients with PAD that undergo revascularization procedures and are fit for such interventions.Expert opinion: Adherence to guideline recommended medical therapy is crucial for improved outcomes in PAD management. Systematic assessment of risk-reduction interventions could help increase adherence to clinically beneficial interventions and improve the overall prognosis of patients with PAD undergoing revascularization procedures. Additionally, optimization of current follow up protocols is needed, with the optimal goal to develop standardized cost-effective algorithms regarding early detection of disease recurrence and re-intervention.

Abstract
PURPOSE Advancements in the endovascular treatment of femoropopliteal atherosclerotic lesions have led to treatment of more complex lesions, particularly long lesions. The aim of this study was to determine the meta-analytic primary patency and need for re-intervention among patients treated for very long lesions (>200 mm) at the femoropopliteal segment and to identify potential risk factors for loss of patency. METHODS This study was performed according to the PRISMA guidelines. A random effects model meta-analysis was conducted, and the I-square was used to assess heterogeneity. RESULTS Fifty-one studies comprised of 3029 patients were included. The mean lesion length was 269 mm. The primary patency rate at 30 days, 6 m, 1-, 2- and 5-years of follow-up was 98%, 76%, 62%, 55%, and 39% respectively. The incidence of TLR was 16% at one year and 32% at two years. The secondary patency rate at 1, 2, 3 and 5 years was 85%, 71%, 64%, and 64% respectively. Heparin bonded ePTFE covered stents (69%) and paclitaxel eluting stents (73%) demonstrated higher 1-year primary patency rates than self-expanding nitinol stents (55%) or uncoated percutaneous transluminal angioplasty (PTA) with provisional stenting (54%). Lesions treated with a heparin bonded ePTFE covered stent had statistically significant higher odds of remaining patent at 1-year of follow-up (OR: 2.74; 95%CI: 1.63-4.61; p < 0.001) than lesions treated with BMS or PTA. Patients with long femoropopliteal lesions causing critical limb ischemia (CLI) developed restenosis or occlusion more often than patients treated for claudication (HR: 1.63; 95%CI: 1.06-2.49; p = 0.026) during an average follow-up of 26 months. CONCLUSION Primary stenting of femoropopliteal TASC D lesions using drug eluting stents or covered stents results in sustained patency over time. PTA or uncoated nitinol stents demonstrated lower patency rates. However, additional comparative studies are needed to determine the efficacy of newer technologies for the treatment of complex femoropopliteal lesions and provide evidence for the most optimal treatment approach.

Abstract
The treatment of chronic total occlusions (CTO) in patients with peripheral arterial disease (PAD) is a complex topic with multiple treatment techniques and treatment strategies. The interventionalist treating patients with PAD should have both a defined treatment algorithm and multiple techniques available for crossing these challenging lesions. This article will cover techniques for treating CTOs and provide an overview of current available evidence.

Abstract
AIMS The crossing of chronic total occlusions (CTOs) is the key step for an endovascular treatment. The Ocelot system is a novel device that combines a steerable drilling tip with optical coherence tomography (OCT) technology. It provides intraluminal imaging to help the crossing of CTOs in the femoropopliteal segment. Aim of the study was to determine early and midterm results after recanalization with this device. METHODS AND RESULTS During a period of 16 months, 84 CTOs were treated using the Ocelot system and prospectively registered. The primary end points were technical success and the primary and secondary patency of the lesion. Risk factors associated with early and midterm results were also analyzed. In all, 58 (69.0%) lesions were treated for intermittent claudication, 26 (31.0%) for critical limb ischemia, 34 (40.5%) were classified as Trans-Atlantic Inter-Society Consensus II D lesions, and 22 (26.2%) showed severe calcifications. The technical success rate was 72.6%. During 36 months of follow-up (mean 25.9), there were 10 reinterventions. The primary and secondary patency at 36 months were 54.2% and 68.1%, respectively. CONCLUSIONS In our experience, the Ocelot system would appear to be a safe and effective tool for increasing the applicability of endovascular techniques. However, the midterm results did not show drastic improvement.

Ann Vasc Surg 2017; 47:179-187. [PMID: 28943491 DOI: 10.1016/j.avsg.2017.09.008] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2017] [Revised: 09/14/2017] [Accepted: 09/14/2017] [Indexed: 11/25/2022]
Abstract
BACKGROUND In patients with severe occlusive disease (Trans-Atlantic Inter-Society Consensus II D [TASC II D]) of the femoropopliteal segment, the advantages of endovascular versus bypass revascularization still remain debated. Most reports available in literature comparing percutaneous transluminal angioplasty (PTA) ± bare metal stent (BMS) versus synthetic bypass analyze patients with heterogeneous anatomical lesions creating possible bias when results of different treatments are matched. In this study, we compared early and midterm outcomes of PTA ± BMS versus heparin-bonded expanded polytetrafluoroethylene graft (Propaten-Gore) + Linton patch in patient affected by symptomatic femoropopliteal TASC II-D lesions. METHODS Eighty limbs with symptomatic severe occlusive disease (TASC II D) of the femoropopliteal segment observed from January 2013 to January 2017 were included in this retrospective study. Indication to treatment was severe claudication in 17 limbs (21.2%) and critical limb ischemia (CLI) in 63 (78.8%). 36.2% of limbs presented at least 2 distal patent vessels, and 63.8% had only 1 patent vessel. Of these limbs, 40 were treated by means of PTA ± BMS (group A), and 40 were treated by means of femoropopliteal bypass with Propaten-Gore graft + Linton patch (group B). Patients were followed with a clinical assessment and duplex at 1, 6, and 12 months after procedure and then annually. A closer follow-up was performed in case of any complication. Patency, reintervention rate, and limb salvage were compared in the 2 groups. RESULTS The mean length of arterial occlusion was 22.1 cm (range, 8-37) in group A versus 25.2 cm (range, 9-41) in group B, P = ns. A slight difference in mean procedural time was observed (83.5 min of group A versus 114 min of group B, minutes, P = 0.02). Mean follow-up was 26.7 months (range, 3-46). Primary patency at 6, 12, and 24 months of group A versus group B was 76.9% vs. 97.5% (P = 0.007), 65.7% vs. 89.1% (P = 0.05), and 52.6% vs. 78.1% (P = 0.005), respectively. Assisted primary patency was 76.9% vs. 97.5% (P = 0.007), 68.5% vs. 91.8% (P = 0.02), and 57.8% vs. 87.5% (P = 0.001), respectively. Secondary patency was 94.8% vs. 97.5% (P = ns), 85.7% vs. 97.2% (P = ns), 73.6% vs. 93.7% (P = 0.004), respectively. Rate of reintervention at 24 months was 45% in group A vs. 20% in group B (P = 0.03). Limb salvage rate at 24 months was 90% for group A vs. 92.5% for group B (P = ns). Univariate analysis showed CLI and poor runoff to be independent risk factors for significant restenosis/occlusion of target artery and reintervention. CONCLUSIONS In patients with severe femoropopliteal occlusive disease (TASC II D), the surgical revascularization by means of Propaten-Gore bypass + Linton patch can be considered safe and effective. Early and midterm results of this approach seem to be superior to PTA ± BMS in terms of restenosis/occlusion and reintervention rates. Larger cohort and longer term results are mandatory to better define this advantage.

Abstract
BACKGROUND Chronic total occlusions (CTOs) are challenging to treat endovascularly. Classic subintimal approach is offering only moderate success rates mainly due of the lack of dedicated crossing catheters. Purpose of this study is to assess the acute procedural success of the use of a novel hydrophilic crossing catheter in the recanalization of peripheral CTOs. MATERIALS AND METHODS This is a retrospective, single-centre study of patients with femoropopliteal CTOs. Revascularization was performed with the use of the NaviCross®- crossing catheter (Terumo Europe). Technical, procedural success and complications were assessed. RESULTS Thirty-two patients were included in the study. Mean age was 65.9 (46-85) years; Critical limb ischemia was the indication for the procedure in 26 (81%). Target vessels included 12 superficial femoral arteries, 9 popliteal, and 11 femoropopliteal segment lesions. Mean length was 85 (50-350) mm; 21(65.6%) lesions were heavily calcified. In all cases a sub-intimal approach was used; in 21 cases the procedure was performed as a day case. Technical success was achieved in 31 (96.8%) cases. Recanalization was achieved with a guidewire in 22 (71%) lesions and with the catheter alone in 9 (29%) cases. Procedural success was achieved in all lesions. No major adverse events occurred. CONCLUSION The use of the NaviCross®- crossing catheter showed high rate of technical and procedural success in challenging femoropopliteal CTOs without significant complications. The use of this catheter needs to be considered as the first approach for CTOs prior to the use of any other more complex re-entry device.

Abstract
Objective This study aimed to evaluate the safety and the efficacy of primary stenting to treat Trans-Atlantic Inter-Society Consensus II (TASC) D femoropopliteal lesions. Background Advances in wire, balloon and stent design have been reported to improve the durability of stenting of longer femoropopliteal lesions. Methods A total of 57 limbs of 53 patients with Rutherford stage 3 to 6 due to TASC D femoropopliteal lesions were treated with a self-expanding nitinol stent in a prospective, single-centre, observational study. End points of interest included primary and secondary patency, target lesion revascularization, in-stent restenosis, major adverse cardiovascular events, Rutherford class improvement and change in walking capacity at 1 year. Results A total of 53 patients (57 lesions) were treated with a self-expanding nitinol stent and final procedural success was 91.2%. The median length of the treated segment was 330 ± 96 mm. The median stented segment was 366 ± 71 mm and the mean number of the stents was 2.1 ± 0.9. At 1 year, primary and secondary patency rates were 63.9% and 82.1%, respectively. Major adverse cardiovascular events occurred in 11 patients (22.9%), and[[strike_start]] [[strike_end]]significant benefits were observed in Rutherford class and walking distance (both P < 0.001). Conclusions Primary implantation of self-expanding nitinol stents for the treatment of TASC D femoropopliteal lesions appears to be safe and effective, especially in patients who have multiple co-morbidities and a high risk for surgical bypass. The risk of restenosis was higher when long stenting was extended to the popliteal artery.

Abstract
Objective To compare the long-term safety and clinical efficacy of endovascular treatment for TASC-II type C/D femoropopliteal lesion compared with TASC-II type A/B femoropopliteal lesion in Korea. Methods A total of 179 limbs [TASC-II A/B femoropopliteal lesion (group I, n = 105 limbs) and TASC-II C/D (group II, n = 74 limbs)] were retrospectively analyzed from patients who underwent angioplasty with or without primary stent implantation between February 2008 and November 2012 at two medical centers in South Korea. The major adverse limb event was defined as a composite of target lesion revascularization, symptom relapse with abnormal ankle brachial index, and major amputation. Results Immediate procedural success rates were not significantly different (96.2% vs. 95.7%, p = 0.450). Although major adverse limb event, mainly driven by symptom relapse with abnormal ankle brachial index, were significantly higher in group II ( p = 0.013), the incidence of major amputation was very low and similar in both groups. Conclusion Even though there were higher incidences of overall procedural complication and major adverse limb event, the technical success rate of endovascular treatment for TASC-II C/D femoropopliteal lesion was comparable to endovascular treatment for TASC-II A/B FPL without an increase in major procedural complications or serious clinical events during follow-up.

Abstract
BACKGROUND In recent years subintimal angioplasty (SIA) has become an established percutaneous procedure for the treatment of symptomatic lower limb arterial chronic total occlusions. However, the clinical benefits of this practice remain unclear. The aim of the review was to determine the effectiveness of SIA on clinical outcomes. This is an update of a review first published in 2013. OBJECTIVES To assess the effectiveness of SIA versus other treatment for people with lower limb arterial chronic total occlusions, determined by the effects on clinical improvement, technical success rate, patency rate, limb salvage rate, and morbidity rates. SEARCH METHODS The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register (last searched January 2016) and Cochrane Central Register of Controlled Trials (CENTRAL) (2015, Issue 12). We also searched clinical trials registries. SELECTION CRITERIA We included data from randomized controlled trials comparing the effectiveness of SIA and any other management method in the treatment of lower limb arterial chronic total occlusions. The primary intervention of interest was SIA, with or without a stent, for the restoration of vessel patency in people with occlusions of a lower limb artery. We compared SIA against alternative modalities used to restore vessel patency, including conventional percutaneous transluminal angioplasty, surgical bypass, or any other treatments. We compared different SIA devices and techniques against each other. DATA COLLECTION AND ANALYSIS Two review authors independently selected trials, assessed trials for eligibility and methodological quality, and extracted data. The third review author resolved disagreements. MAIN RESULTS Two studies, involving a total of 147 participants with TransAtlantic Inter-Society Consensus (TASC)-II D femoropopliteal lesions, met our inclusion criteria and were included in the review. Both studies were small but otherwise of high methodological quality. However, the treatment techniques and control groups of the two studies differed, precluding the combining of study results and resulting in the evidence being less applicable. We therefore considered the quality of the evidence to be low.In one study, participants with TASC-II D lesions were randomized to receive either SIA with stenting of the superficial femoral artery or remote endarterectomy (RE) with stenting of the superficial femoral artery. Three-year follow-up results showed a Rutherford classification improvement of 64% in the SIA group compared to 80% in the RE group (risk ratio (RR) 0.79, 95% confidence interval (CI) 0.61 to 1.03; 95 participants; P = 0.079). Postexercise ankle brachial index improvements (defined as an increased value of 0.2) were reported in 70% of participants in the SIA group compared to 82% in the RE group (RR 0.86, 95% CI 0.68 to 1.08; 95 participants; P = 0.18). The study reported the technical success rate was 93% for the SIA group and 96% for the RE group (RR 0.97, 95% CI 0.88 to 1.07; 95 participants; P = 0.91). Primary patency at 12 months was 59.1% in the SIA group compared to 78.4% in the RE group (RR 0.75, 95% CI 0.57 to 1.00; 95 participants; P = 0.05). Primary patency at 24 months was 56.8% in the SIA group compared to 76.5% in the RE group (RR 0.74, 95% CI 0.55 to 1.00; 95 participants; P = 0.05) and 47.7% in the SIA group and 62.7% in the RE group at 36 months (RR 0.76, 95% CI 0.52 to 1.11; 95 participants; P = 0.15). Assisted primary patency was 52.3% in the SIA group compared to 70.6% in the RE group (P = 0.01) at 36 months. Secondary patency was better for the RE group (P = 0.03) at 36 months. Limb salvage at three years' follow-up was 95% in the SIA group and 98% in the RE group (RR 0.97, 95% CI 0.90 to 1.05; 95 participants; P = 0.4). There were no perioperative deaths, but complications occurred in two SIA participants (femoral pseudoaneurysm and pulmonary edema) and in three RE participants (seroma, femoral pseudoaneurysm, superficial femoral artery acute occlusion).In the second study, the effects of the SIA OUTBACK re-entry catheter device in people affected by TASC-II D superficial femoral artery chronic total occlusion were compared with the SIA manual re-entry technique. This study did not report clinical improvement and limb salvage. Technical success was achieved in all cases in both the OUTBACK device and manual groups. The primary 6-month patency rate was 100% in the OUTBACK group (26 of 26 participants) compared to 96.2% in the manual group (25 of 26 participants) (RR 1.04, 95% CI 0.94 to 1.15). The primary 12-month patency rate was 92.3% in the OUTBACK group (24 of 26 participants) compared to 84.6% in the manual group (22 of 26 participants) (RR 1.09, 95% CI 0.90 to 1.33). Patency rates at 24 and 36 months were not reported. The study reported that there were no complications. AUTHORS' CONCLUSIONS Using the GRADE approach, we classified the quality of the evidence presented by both studies in this review as low due to small study size and the small number of studies. In addition, the two included trials differed from each other in the techniques and control used, and we were therefore unable to combine the data. Consequently there is currently insufficient evidence to support SIA over other techniques. Evidence from more randomized controlled trials is needed to assess the role of SIA in people with chronic lower limb arterial total occlusions.

Abstract
Endovascular management of chronic total occlusions (CTO) can be challenging both from decision-making and technical perspectives. Successful treatment and management of a CTO requires the operator to have an understanding of the salient imaging findings, a thorough knowledge of the various technical challenges of the procedure, and comprehension of the importance and necessity of long-term clinical management. This article outlines a general approach to endovascular management of lower limb CTOs and discusses indications, techniques, potential complications, and therapeutic options of the procedure.

Abstract
Development of aortoiliac occlusive disease (AIOD) is associated with classic risk factors for atherosclerotic disease such as hyperlipidemia, hypertension, diabetes, or smoking. Risk factor modification, smoking cessation, and prevention of cardiovascular events remain the cornerstones of AIOD management. Symptom improvement and limb loss prevention are considered secondary goals of therapy. Continuous technological advances, new devices, as well as new revascularization techniques are constantly changing the landscape of AIOD management. Surgical interventions, which were considered a gold standard therapy for nearly 50 years, currently give way to newer and less invasive endovascular techniques.

Ann Vasc Surg 2014; 28:1686-96. [PMID: 24709402 DOI: 10.1016/j.avsg.2014.03.033] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2013] [Revised: 02/22/2014] [Accepted: 03/15/2014] [Indexed: 10/25/2022]
Abstract
BACKGROUND The 1-year results of the prospective register STELLA suggested that primary stenting of long femoropopliteal (FP) lesions (≥15-cm) was a sure and effective treatment. However, the long-term results of this technique remain unknown. METHODS STELLA is a prospective monocentric register of patients treated for FP lesions ≥15-cm (Trans-Atlantic Inter-Society Consensus [TASC] C and D) by direct stenting (Flexstar(®), Bard). The patients with de novo atheromatous lesions were included between November 2008 and October 2009 when the guidewire had crossed the lesion. Restenoses were excluded. The follow-up was coordinated by a clinical research assistant. Clinical and ultrasound evaluation were carried out every 3 months for 12 months, then every 6 months up to 30 months. Restenosis was defined by an index of peak systolic velocity >2.4. RESULTS Among the 58 patients (62 limbs) included, 40.3% presented an effort ischemia and 59.7% a critical ischemia (CI). The mean age was 71 ± 12 years. The lesions were classified as TASC D in 37.1% of the cases. The median length of the stenting was 26 ± 18 cm. The average follow-up was 26.1 months (1-30). At 30 months, a complete follow-up was obtained in 55 patients (58 limbs). The rate of survival was 79.6%. Nine of the 11 patients deceased presented initially with CI. Death was in connection with CI in 2 cases. At the date of latest news, 98.3% of the patients were under antiaggregating treatment, 20% received antivitamin K treatment, 75% received statins, and 75% received angiotensin-converting-enzyme inhibitors. The rates of maintenance of the primary and secondary clinical improvement were 68.6 ± 6.0% and 82.6 ± 5.1% at 12 months and 65.1 ± 6.2% and 78.4 ± 5.6% at 30 months, respectively. The mean Rutherford index was 4.1 ± 1.0 in preoperative, 0.7 ± 1.2 at 12 months, and 0.6 ± 1.1 at 30 months (P < 0.001). Two major amputations were carried out at 9 and 28 months for patients initially with CI. The mean systolic pressure index was 0.6 ± 0.1 in preoperative and 1.0 ± 0.2 at 1-year and 0.9 ± 0.3 at 30 months (P < 0.001). The rates of primary and secondary patency were 66 ± 6.3% and 80.9 ± 9.5% at 12 months and 62.2 ± 6.6% and 77.2 ± 5.9% at 30 months, respectively. Between 0 and 12 months, 12 (19.3%) intrastent restenosis (ISR) were noted. One ISR was observed after 12 months. At the same period, we observed 11 and 1 target lesion revascularization, respectively. CONCLUSIONS In the long run, the primary stenting of long FP lesions (≥15-cm) is a safe and durable treatment. A strong clinical and ultrasound monitoring is indicated during the first year to maintain the clinical improvement.

Abstract
A best evidence topic in surgery was written according to a structured protocol. The question addressed how subintimal angioplasty (SIA) compares to transluminal angioplasty (TA) for the treatment of femoral occlusive disease. One hundred and thirty two papers were found using the reported search; the 5 which represented the best evidence to answer the question are discussed. The evidence on this subject is limited; there are no randomised controlled trials (RCTs) comparing SIA to TA for pathologically equivalent lesions. However SIA remains a safe and effective alternative to surgical bypass grafting when TA cannot be performed.

Abstract
PURPOSE The purpose of this article is to report the results of a prospective single-center study analyzing the long-term clinical and angiographic outcomes of subintimal angioplasty (SIA) for the treatment of chronic total occlusions (CTOs) of the femoropopliteal artery. MATERIALS AND METHODS Patients with severe intermittent claudication or critical limb ischemia (CLI) were enrolled in the study. All lesions were treated with SIA and provisional stenting. Primary end points were technical success, patient survival, limb salvage, lesion primary patency, angiographic binary restenosis (>50%), and target lesion revascularization (TLR). Regular clinical and angiographic follow-up was set at 6 and 12 months and yearly thereafter. Study end points were calculated with life-table survival analysis. Proportional-hazards regression analysis with a Cox-model was applied to adjust for confounding factors of heterogeneity. RESULTS Between May 2004 and July 2009, 98 patients (105 limbs, patient age 69.3±9.9 years) were included in the study. Technical success rate was 91.4% with a lesion length of 121±77 mm. Limb-salvage and survival rates were 88.7% and 84.1% at 3 years, respectively. After 12, 24, and 36 months, primary patency was 80.1%, 42.3%, and 29.0%, angiographic binary restenosis was 37.2%, 68.6%, and 80.0%, and TLR was 84.8%, 73.0%, and 64.5%, respectively. CLI was the only adverse predictor for decreased primary patency (hazard ratio [HR] 0.36; 95% confidence interval [CI] 0.16-0.80, p=0.012), whereas significantly less restenosis was detected after spot stenting of the entry and/or re-entry site (HR 0.31; 95% CI 0.10-0.89, p=0.01 and HR 0.20; 95% CI 0.07-0.56, p=0.002, respectively). CONCLUSIONS Subintimal angioplasty is a safe and effective revascularization technique for the treatment of CTOs of the femoropopliteal artery. Provisional stenting may have a role at the subintimal entry or true lumen re-entry site.

Abstract
OBJECTIVES This study investigated the results with primary stenting using the Protégé EverFlex 200-mm-long self-expanding nitinol stent (ev3 Endovascular Inc, Plymouth, Minn) in femoropopliteal TransAtlantic Inter-Society Consensus (TASC) C and D lesions of at least 150 mm in length. METHODS Between March 2008 and June 2009, 100 patients (66 men) presenting with 100 symptomatic TASC C and D femoropopliteal lesions were treated with at least one 200-mm-long Protégé EverFlex stent. The intention of this study was to treat all lesions with as few stents as possible. The primary study end point was primary patency at 12 months, defined as the absence of hemodynamically significant stenosis on duplex ultrasound imaging (systolic velocity ratio <2.4) at the target lesion and without target lesion revascularization (TLR) ≤12 months. Stent fracture occurrence was assessed at the 12-month follow-up by conventional x-ray imaging. RESULTS Average patient age was 70 years. Preoperative symptom assessment reported 71 patients (71%) had claudication vs 29 (29%) with critical limb ischemia. Average lesion length was 242 mm (range, 160-450 mm), and 27 patients (27%) presented with popliteal involvement. A total of 158 Protégé EverFlex stents were used to treat 100 lesions. Kaplan-Meier estimation reported a 12-month freedom from target lesion revascularization of 68.2% and a primary patency rate of 64.8%. Stent fractures occurred in six patients (6.0%) when x-ray images taken immediately after the procedure were compared with those taken after 1 year. CONCLUSIONS The results of our Durability-200 study show an acceptable primary patency rate after 1 year was obtained in this patient cohort with TASC C and D femoropopliteal lesions.
