Comparison of Different Endovascular Treatments of Femoropopliteal Artery In-Stent Restenosis: A Systematic Review and Bayesian Network Meta-Analysis. Ann Vasc Surg 2024; 104:205-216. [PMID: 38492725 DOI: 10.1016/j.avsg.2023.12.081] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Revised: 12/07/2023] [Accepted: 12/18/2023] [Indexed: 03/18/2024]
Abstract
BACKGROUND This Bayesian network meta-analysis (NMA) sought to evaluate the efficacy of different endovascular treatments for femoropopliteal artery in-stent restenosis (FP-ISR). METHODS PubMed, Embase, Cochrane Central Register of Controlled Trials, and Web of science for clinical trials from database inception to March 31, 2023, with no language restrictions to retrieve randomized controlled trials or cohort studies evaluating the impact of any kind of endovascular treatments for FP-ISR. Pair-wise meta-analysis and Bayesian NMA were performed to pool the outcome estimates different endovascular treatments. The primary end points under consideration were primary patency rates at both 6-month and 12-month follow-up. RESULTS A total of 15 studies with 1,424 patients were ultimately enrolled to be analyzed, 7 types of endovascular treatment were identified for comparison. In terms of primary patency and freedom from target lesion revascularization (TLR) at 6-month and12-month follow-up, the direct meta-analysis findings showed that drug-coated balloons (DCB) and covered stent (CS) are considerably superior to plain old balloon angioplasty (POBA), Excimer laser atherectomy (ELA) + DCB is significantly better than DCB. According to the meta-analysis based on Bayesian theory, during the 6-month and 12-months follow-up, we could not find significant difference between the different treatments in terms of the primary patency and the freedom from TLR, based on the surface values under the cumulative ranking curve (SUCRA), CS was considered the best treatment in terms of primary patency (6 months SUCRA = 85.2; 12 months SUCRA = 78.9) and freedom from TLR (6 months SUCRA = 84.9; 12 months SUCRA = 70.9); directional atherectomy + POBA may lead to higher survival rate at 12 months (SUCRA = 89.1) than others treatments; in addition, both ELA + POBA and ELA + DCB have higher limb salvage than POBA. CONCLUSIONS The findings of this NMA suggest that CS showed positive encouraging results in primary patency and TLR in FP-ISR at 6 and 12 months. However, due to the potential influence of certain confounding factors, the long-term results necessitate validation through numerous randomized controlled trials.

Outcomes of Excimer Laser Ablation Combined with Drug-coated Balloon in Atherosclerotic Lesions of the Popliteal Artery. Ann Vasc Surg 2024; 104:196-204. [PMID: 38492729 DOI: 10.1016/j.avsg.2023.12.091] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Revised: 12/14/2023] [Accepted: 12/18/2023] [Indexed: 03/18/2024]
Abstract
BACKGROUND The treatment of atherosclerotic lesions in the popliteal artery is challenging. This study aims to investigate the efficacy and safety of excimer laser ablation (ELA) combined with drug-coated balloon (DCB) for these lesions. METHODS From June 2019 to December 2021, data of patients who underwent ELA combined with DCB in the popliteal artery were retrospectively reviewed. Demographics, lesion characteristics, periprocedural complications, and follow-up information were analyzed. The primary endpoint was primary patency. Secondary endpoints included major amputation-free survival rate, technical success, bailout stenting, clinically-driven target lesion reintervention, improvement of ankle-brachial index (ABI), and Rutherford class. RESULTS A total of 61 patients were enrolled. The mean age was 73.4 ± 11.7 years. 20 (32.8%) patients had stenotic lesions, while 41 (67.2%) patients had chronic total occlusions. The mean length of these lesions was 7.3 ± 2.8 cm. Procedure technical success rate was 95.1%. Bailout stent was performed in 3 (4.9%) patients. Intraprocedural distal embolization occurred in 3 (4.9%) patients, while flow limiting dissections occurred in 3 (4.9%) patients. The mean ABI was significantly improved from 0.45 ± 0.13 at baseline to 0.90 ± 0.12 after ELA, 0.88 ± 0.11 at 6 months and 0.85 ± 0.12 at 12 months during the follow-up period. The median follow-up time was 28.2 ± 6.1 months. Reintervention was performed in 5 (8.2%) patients. The 2-year primary patency was 83.5%. CONCLUSIONS ELA combined with DCB is a safe and effective strategy in the treatment of popliteal artery atherosclerotic lesions with low rates of bail-out stenting and high primary patency.

Abstract
BACKGROUND Chronic limb-threatening ischemia (CLTI) is characterized by rest pain and tissue loss, with an annual mortality rate of 20% and amputation rate of 40%, if not treated. Open bypass surgery is recommended in CLTI, depending on the availability of good quality venous material, outflow artery patency, and surgical expertise. The aim of the study is to analyze primary patency, limb salvage, and survival rate in patients undergoing popliteal-to-distal bypass. METHODS All consecutive patients who underwent popliteal-to-distal bypass surgery between January 2016 and December 2021 were enrolled in the study. Primary outcomes were primary patency, limb salvage, and overall survival. Secondary outcomes included amputation-free survival and secondary patency. RESULTS Forty-nine patients were included during the study. Technical success was achieved in 100% of cases. Target outflow artery was in 27% (n. 13) of cases the anterior tibial artery, in 27% (n. 13) the dorsalis pedis, in 2% (n. 1) the peroneal artery, in 30% (n. 15) the retromalleolar tibial artery, in 10% (n. 5) the medial plantar artery, and in 4% (n. 2) the tarsal artery. Two-year primary patency was 85% ± 5. Secondary patency rates were 86% ± 3 at 2 years. The overall survival was 81% ± 6 at 2 years, the amputation-free survival was 70% ± 9, and the limb salvage rate was 81% ± 6. CONCLUSIONS Popliteal-to-distal bypass requires high technical expertise to be performed. When a good autologous vein and adequate outflow artery are present, they can be feasible with good patency rates and overall survival.

Abstract
In endovascular therapy (EVT) for femoropopliteal artery (FPA) lesions, studies examining the relationship between lesion morphology and hemodynamic status are limited. The purpose of this study was to investigate FPA lesion characteristics, including imaging findings and their cutoff values that can predict hemodynamic significance after balloon angioplasty. This single-center retrospective study enrolled 50 de novo FPA lesions from 43 patients treated under intravascular ultrasound (IVUS) usage between June 2022 and March 2023. As a physiological parameter, the pressure gradient was measured, and the cutoff value of the residual pressure gradient (RPG) was defined as a systolic pressure > 10 mmHg through the lesions after balloon angioplasty. The pressure gradients were measured using a 0.014-inch wire-guided, rapid exchange-type microcatheter, Navvus II (Acist, Eden Prairie, Minnesota, USA). Predictive risk factors for RPG were analyzed using the random forest (RF) method. The relationship between the variables, RPG, and the cutoff points of each predictor was assessed using the partial dependence plot (PDP) method. RPG was observed in 20% of the lesions after balloon angioplasty. The RF model revealed that the percent diameter stenosis (%DS) and minimum lumen area (MLA) on IVUS assessment were strong predictive factors for RPG after balloon angioplasty. The PDP model revealed that a higher %DS (cutoff 30%) and smaller MLA (cutoff 10 mm2) could predict RPG after balloon angioplasty. Conventional lesion parameters such as %DS and MLA can predict hemodynamic significance during EVT for FPA lesions.

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

Abstract
OBJECTIVE Percutaneous transmural arterial bypass (PTAB) using the DETOUR system aims to create a percutaneous, endovascular femoropopliteal bypass for the treatment of long segment, complex superficial femoral and proximal popliteal artery disease. The goal of the DETOUR2 study is to investigate the safety and effectiveness of the therapy in comparison with pre-established performance goals. METHODS The DETOUR2 investigational device exemption study is a prospective, single-arm, multicenter, international trial of symptomatic peripheral arterial disease patients (Rutherford classes 3-5) undergoing the DETOUR procedure for long segment (>20 cm) superficial femoral artery disease. Prespecified end points included primary safety (composite of major adverse events) at 30 days, and effectiveness (primary patency defined as freedom from restenosis or clinically driven target lesion revascularization) at 1 year. RESULTS We enrolled 202 patients at 32 sites with 200 treated with the DETOUR system. The mean lesion length was 32.7 cm, of which 96% were chronic total occlusions (CTO) and 70% were severely calcified. Technical success was achieved in 100% of treated patients. The primary safety end point was met with a 30-day freedom from major adverse event rate of 93.0%. The 1-year primary effectiveness end point was met with 72.1% primary patency at 12 months. Primary-assisted and secondary patency were 77.7% and 89.0%, respectively, at 12 months. The 12 month deep venous thrombosis incidence was 4.1% with no pulmonary emboli reported. Venous quality-of-life scores showed no significant changes from baseline. There was a Rutherford improvement of at least one class through 12 months in 97.2% of patients. The mean ankle-brachial index also improved from 0.61 to 0.95 during this period. There were marked improvements in quality-of-life and functional status measures. CONCLUSIONS The DETOUR2 study met both the primary safety and effectiveness end points, demonstrating clinical usefulness of this novel therapeutic strategy in long femoropopliteal lesions.

Abstract
Popliteal artery entrapment syndrome (PAES) is a rare vascular disease, and cases of bilateral PAES associated with distinct symptoms in each of the affected legs are very rare. In an effort to improve current understanding regarding the presentation and treatment of this condition, a case of bilateral PAES is herein described with a corresponding review of the associated literature. The overall process of diagnosing and treating one patient affected by bilateral PAES was retrospectively assessed to provide comprehensive insight regarding this disease. This patient was diagnosed via contrast-enhanced computed tomography (CT), and right-sided symptomatic PAES was successfully treated via autogenous saphenous venous graft arterial bypass surgery. In contrast, the asymptomatic left-sided PAES in this patient was subject to close follow-up monitoring. Over a 2-year postoperative follow-up period, this patient did not experience any symptoms or complications. As such, autogenous saphenous venous graft arterial bypass surgery represents a safe and efficacious means of treating PAES, whereas surgery may not be required for cases of asymptomatic PAES even in patients with a bilateral presentation.

Abstract
PURPOSE The previous single-arm registries showed the acceptable primary patency after endovascular therapy (EVT) using covered stent-graft (CSG) and Supera interwoven nitinol stent (Supera peripheral stent [SPS]) in calcified femoropopliteal lesions. The aim of this study was to compare the safety and efficacy between CSG and SPS in calcified femoropopliteal lesions in clinical practice. MATERIALS AND METHODS We retrospectively analyzed 341 cases who had Rutherford class 2 to 6 peripheral artery disease and underwent EVT with either CSG (n=137) or SPS (n=204) for femoropopliteal lesions with bilateral calcification in fluoroscopic image, based on the Peripheral Arterial Calcium Scoring System (PACSS) classification, between April 2017 and February 2021 at 7 cardiovascular centers in Japan. RESULTS After propensity score (PS) matching, the final study population consisted of 150 matched patients with no remarkable intergroup difference in baseline characteristics. The primary patency at 1 year was not statistically different between CSG and SPS groups (81.4% vs 71.2%, p=0.32). There was also no significant difference in freedom from target lesion revascularization (82.8% vs 77.6%, p=0.28) and overall survival rate (88.6% vs 87.2%, p=0.81). The stratification analysis demonstrated that advanced age, current smoking, diabetes mellitus, and PACSS grade 4 had a significant interaction on the association of CSG versus SPS implantation with restenosis (interaction p<0.05). CONCLUSIONS In patients with bilaterally calcified femoropopliteal lesions, 1-year primary patency was not significantly different between treatments using CSG and SPS after the PS matching. CLINICAL IMPACT Covered stent-graft (CSG) and Supera interwoven nitinol stent (SPS) are reliable endovascular devices in calcified femoropopliteal lesions. This retrospective multicenter study compared the clinical outcomes between the two devices. After propensity score matching, 150 matched patients with no remarkable intergroup difference in baseline characteristics. The primary patency at 1 year was not statistically different between the CSG and SPS group (81.4% vs. 71.2%, p=0.32). There was also no significant difference in freedom from target lesion revascularization (82.8% vs. 77.6%, p=0.28) and overall survival rate (88.6% vs 87.2%, p=0.81). The two devices showed the similar efficacy in calcified femoropopliteal lesions.

Abstract
BACKGROUND Functional popliteal entrapment syndrome (FPES) is an under-recognized source of leg pain caused by dynamic compression of the popliteal vessels by surrounding musculature in the absence of anatomic abnormality. Late recognition and difficulty capturing this entity across imaging modalities can lead to significant morbidity in an often young and active patient population. Surgical outcomes and optimal diagnostic strategies remain uncertain. METHODS We performed a retrospective cohort study of all patients undergoing surgical decompression for FPES at an academic medical center between 2018 and 2022. Preoperative symptoms, patient characteristics, imaging, operative details, and follow-up were captured. The primary outcome was symptomatic improvement at last clinic visit. Secondary outcomes included symptomatic improvement at 6 months and postoperative complications. RESULTS A total of 24 extremities (16 patients) were included. The mean ± standard deviation age was 23.3 ± 6.4 years and 75.0% of patients were female. The median symptom duration before decompression was 27 months (interquartile range, 10.7-74.6 months). Preoperative symptom severity in the affected extremity was as follows: 33.3% limited from peak exercise, 25% unable to exercise, and 41.7% with debilitating symptoms that affected activities of daily living. Preoperative imaging with provocative maneuvers included duplex ultrasound (87.5%), magnetic resonance angiography (100%), and digital subtraction angiography (100%). Using digital subtraction angiography as the gold standard, the sensitivity for detection of FPES was 85.7% for duplex examination and 58.3% for magnetic resonance angiography. The median follow-up was 451 days (interquartile range, 281-635 days). Most patients demonstrated durable improvement in the affected extremity, with 29.2% realizing complete resolution of symptoms and 37.5% reporting symptomatic improvement at last clinic visit for a total of 66.7%; 20.8% had initial improvement, but developed recurrent symptoms and were found to have elevated compartment pressures consistent with chronic exertional compartment syndrome and were treated with formal fasciotomy. Repeat decompression was required in one extremity (4.2%) owing to recurrent symptoms. Two patients (8.3%) had minimal or no improvement in their affected extremity and workup for the cause of continued discomfort was ongoing. CONCLUSIONS Delays in diagnosis of FPES are common. Provocative maneuvers until replication of symptoms across multiple imaging modalities may be necessary to reliably identify the disease process. Surgical decompression improved or completely resolved symptoms in two-thirds of extremities. Treating physicians should maintain suspicion for comorbid chronic exertional compartment syndrome, especially if symptoms recur or persist after decompression.

Abstract
Below-the-knee (infrapopliteal) atherosclerotic disease, which presents as chronic limb-threatening ischemia (CLTI) in nearly 50% of patients, represents a treatment challenge when it comes to the endovascular intervention arm of management. Due to reduced tissue perfusion, patients usually experience pain at rest and atrophic changes correlated to the extent of the compromised perfusion. Unfortunately, the prognosis remains unsatisfactory with 30% of patients requiring major amputation and a mortality rate of 25% within 1 year. To date, randomized multicentre trials of endovascular intervention have shown that drug-eluting stents (DES) increase patency rate and lower target lesion revascularization rate compared to plain balloon angioplasty and bare-metal stents. The majority of these trials recruited patients with focal infrapopliteal lesions, while most patients requiring endovascular intervention have complex and diffuse atherosclerotic disease. Moreover, due to the nature of the infrapopliteal arteries, the use of long DES is limited. Following recent results of drug-coated balloons (DCBs) in the treatment of femoropopliteal and coronary arteries, it was hoped that similar effective results would be achieved in the infrapopliteal arteries. In reality, multicentre trials have failed to support the proposed hypothesis and no advantage was found in using DCBs in comparison to plain balloon angioplasty. This review aims to explore anatomical, physiological and pathological differences between lesions of the infrapopliteal and coronary arteries to explain the differences in outcome when using DCBs.

Abstract
PURPOSE Drug-coated balloon (DCB) angioplasty and laser atherectomy (LA) have been frequently utilized to treat femoropopliteal in-stent restenosis (ISR); however, no studies have concurrently compared available regimens, including DCB, LA+DCB, and LA + plain balloon angioplasty (PB). Therefore, we conducted this network meta-analysis to determine whether there were significant differences in outcomes among these regimens. MATERIALS AND METHODS A comprehensive search was conducted in PubMed, EMBASE, and the Cochrane library to identify all randomized controlled trials comparing DCB or LA-based regimes with POBA or each other for treating femoropopliteal in-stent restenosis (ISR) from their inception until March 2021. The primary outcome measure was binary restenosis, and secondary outcome measures were target lesion revascularization (TLR) and mortality, evaluated at 6 and 12 months, respectively. Statistical analysis was performed using Aggregate Data Drug Information System (ADDIS) 1.4 software, and all data were graphically summarized using Microsoft Excel software. RESULTS The final analysis included 11 studies, of which 6 studies compared DCB with PB, 2 studies compared PB vs LA+PB, 2 studies compared DCB vs LA+DCB, and 1 study compared LA+DCB with LA+PB. DCB was better than PB in decreasing binary restenosis at 6 (odds ratio [OR]: 0.22, 95% credible interval [CrI]: 0.04-0.91) and 12 (OR: 0.26, 95% CrI: 0.12-0.50) months. DCB was associated with lower TLR than PB at 6 months (OR: 0.31, 95% CrI: 0.13-0.69). LA+DCB was also superior to PB in treating binary restenosis at 12 months (OR: 6.10, 95% CrI: 1.94-24.41) and TLR at 6 months (OR: 5.32, 95% CrI: 1.43-28.06). There was no statistical difference in mortality between PB, DCB, and LA+PB. DCB and LA+DCB were the first 2 options for reducing binary restenosis and TLR. CONCLUSION The current network meta-analysis demonstrates that both DCB and LA+DCB are superior to PB alone, and that DCB and LA+DCB may be the preferred treatment options for reducing binary restenosis and TLR. CLINICAL IMPACT The treatment for femoropopliteal in-stent restenosis (ISR) remains challenging clinical practice. One important reason is that no optimal treatment strategy was available. Drug-coated balloon angioplasty (DCB) and laser atherectomy (LA) have been extensively utilized to treat ISR; however, different combinations of these treatments further confused the clinicians' choices. This network meta-analysis systematically investigated the difference between the currently available treatments regarding therapeutic effects and safety, indicating that DCB and LA+DCB may be the optimal treatment for decreasing the risk of binary restenosis and target lesion revascularization. The results of the current network meta-analysis help to resolve the confusion of clinicians in making the decision.

Abstract
OBJECTIVE To evaluate the safety and effectiveness of drug-coated balloon angioplasty (DCB) in isolated popliteal lesions. BACKGROUND The benefit of using DCB in femoropopliteal arteries including the proximal popliteal artery has been demonstrated, but has not yet been evaluated for isolated popliteal lesions. METHODS This retrospective, single-center study includes patients requiring treatment with DCB of isolated popliteal lesions. Two cohorts matched (Plain old balloon angioplasty (POBA) versus DCB) by their baseline and lesion characteristics were compared. Lesions receiving bail-out stents were excluded. Primary endpoint was the 1-year target lesion revascularization (TLR) rate. Secondary endpoints included the procedural success and complication rate, primary patency, changes in Rutherford-Becker class (RBC) and ankle-brachial index (ABI). RESULTS One hundred and seven patients were included in this study. More than one third of the patients had critical limb threatening ischaemia (CLTI) (35 % (POBA) versus 40.4 % (DCB), p = 0.354. The technical success rate of the procedure was 85.1 % (n = 40/47) in the DCB group and 83.3 % (n = 60) in the POBA group (p = 0.510). There were three complications in the POBA group (5.0 %) but none in the DCB group (p = 0.172). After 12 months, in the entire cohort 14 patients (13.1 %) had to undergo a TLR. The TLR-free survival was 81.7 % in the POBA and 93.6 % in the DCB group (p = 0.060). Primary patency rates after POBA and DCB were 65.1 % and 87.5 % at 6 months (p = 0.024), respectively. At 12 months, the patency rates were 71.7 % and 85.1 % (p = 0.076), respectively. For both treatment arms, there was a significant improvement in ABI and RBC compared to baseline. Four patients from the DCB group and two from the POBA group received a minor amputation (p = 0.232). One patient in the DCB group died within 12 months. CONCLUSION After one year the use of DCB is by trend more effective for the treatment of isolated popliteal stenosis compared to POBA. A larger scale prospective study is mandatory.

Randomized Trial Comparing a Stent-Avoiding With a Stent-Preferred Strategy in Complex Femoropopliteal Lesions. JACC Cardiovasc Interv 2024; 17:1134-1144. [PMID: 38749594 DOI: 10.1016/j.jcin.2024.03.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Revised: 03/05/2024] [Accepted: 03/12/2024] [Indexed: 06/15/2024]
Abstract
BACKGROUND Limited comparative data exist on different interventional strategies for endovascular revascularization of complex femoropopliteal interventions. OBJECTIVES In this study, the authors aimed to compare a stent-avoiding (SA) vs a stent-preferred (SP) strategy, promoting optimal lesion preparation and the use of drug-eluting technologies in both arms. METHODS Within a prospective, multicenter, pilot study, 120 patients with symptomatic complex femoropopliteal lesions (Rutherford classification 2-4, mean lesion length 187.7 ± 78.3 mm, 79.2% total occlusions) were randomly assigned in a 1:1 fashion to endovascular treatment with either paclitaxel-coated balloons or polymer-coated, paclitaxel-eluting stents. Lesion preparation including the use of devices for plaque modification and/or removal was at the operators' discretion in both treatment arms. RESULTS In the SA group, lesion preparation was more frequently performed (71.7% SA [43/60] vs 51.7% [31/60] SP; P = 0.038) with a high provisional stenting rate (48.3% [29/60]). At the 12-month follow-up, primary patency was 78.2% (43/55) in the SA group and 78.6% (44/56) in the SP group (P = 1.0; relative risk: 0.995; 95% CI: 0.818-1.210). Freedom from major adverse events was determined in 93.1% (54/58) in the SA group and in 94.9% (56/59) in the SP group (P = 0.717; relative risk: 0.981; 95% CI: 0.895-1.075), with all adverse events attributable to clinically driven target lesion revascularization. CONCLUSIONS Both endovascular strategies promoting lesion preparation before the use of drug-eluting devices suggest promising efficacy and safety results in complex femoropopliteal procedures with a high proportion of total occlusions through 12 months. Ongoing follow-up will show whether different results emerge over time. (Best Endovascular Strategy for Complex Lesions of the Superficial Femoral Artery [BEST-SFA]; NCT03776799).

Abstract
BACKGROUND Complex femoropopliteal artery disease represents a challenge. The Supera stent holds the promise of improving the results of endovascular therapy for complex femoropopliteal disease. AIMS We aimed at appraising the early and long-term effectiveness of the Supera stent after successful subintimal angioplasty (SuperSUB strategy) for complex femoropopliteal lesions. METHODS We conducted a multicenter, prospective, single-arm observational study including consecutive patients at participating centers in whom Supera was implanted after successful subintimal angioplasty for complex femoropopliteal lesions. RESULTS A total of 92 patients were included Femoropopliteal arteries were the most common target, and lesion length was 261 ± 102 mm. Most procedures were technically demanding, with antegrade femoral access in 35 (38%) and retrograde distal access in 55 (60%). Supera stent length was 281 ± 111 mm, with 4, 5, and 6 mm devices being most commonly used: 32 (35%), 35 (38%), and 23 (25%), respectively. Technical success was achieved in 100% of subjects, as was clinical success (per subject), whereas procedural success (per subject) was obtained in 98%. At 24 months, freedom from clinically driven target lesion revascularization was 93%, whereas primary patency was 87%. When compared with a similar historical cohort, Supera stent use appeared to be associated with a reduction in resources. CONCLUSION Use of Supera stent after successful subintimal recanalization of complex lower limb arterial lesions yields favorable procedural results, which are maintained over follow-up, and are associated also with a favorable resource use profile.

Abstract
PURPOSE To describe our clinical experience of endovascular exclusion of popliteal artery aneurysms using the new self-expandable covered stent SOLARIS® (Scitech Medical, Brazil), and to report its results in the context of surgical and endovascular treatment of popliteal artery aneurysms. CASE REPORT Among 20 popliteal artery aneurysms undergoing open or endovascular repair in 2022 and 2023, two patients were successfully treated with the Solaris stentgraft. Both patients had a patent popliteal artery and three run-off vessels. After stentgraft implantation, they received dual antiplatelet therapy for three months and they were followed-up with Duplex scan and clinical evaluation after three months, and every six months thereafter. After three months, one Solaris stentgraft had complete thrombosis and the other ruptured, requiring surgical removal. No complications were observed among the other aneurysms treated with open repair or with the Viabahn® stentgraft. CONCLUSIONS Endovascular treatment of popliteal aneurysms with the new covered self-expandable stent Solaris resulted in severe complications in the two cases reported, and in worse short-term outcomes than endovascular repair with Viabahn® and open repair. Its off-label use to treat popliteal artery aneurysms should be therefore discouraged.

Abstract
Drug-coated balloons (DCBs) have been widely used in endovascular therapy for femoropopliteal arteries with atherosclerotic lesions. Vascular response after DCBs remains unclear. This mini-review proposes a possible mechanism of restenosis after the DCB strategy. Balloon dilatation including DCBs expands the vascular lumen by producing dissections, which is composed of the original vascular lumen and the cavity surrounded by dissected flaps. The cavity surrounded by dissected flaps is eventually replaced with the thrombus in the healing process after balloon dilatation. However, the thrombus may propagate to the expanded vascular lumen through the entry point of the dissection. Subsequently, the thrombus both in the cavity and the expanded lumen would be organized over time. The vascular lumen in the chronic-phase after DCBs may be influenced by the propagated thrombus from the cavity surrounded by dissected flaps.

Abstract
OBJECTIVE To investigate dissection severity, need for bailout stenting and limb outcomes in patients undergoing antegrade vs. retrograde revascularisation. METHODS Consecutive patients who underwent either antegrade or retrograde revascularisation after failed antegrade recanalisation of long femoropopliteal chronic total occlusion (CTO) due to symptomatic peripheral artery disease between January 2017 and June 2022 were studied. Retrospective case control matching was used to adjust for lesion length and calcification using the peripheral artery calcification scoring system (PACSS). Procedural outcomes included severity of dissection (Type A to F dissections, numerically graded on a scale from 0 - 6 with increasing severity) after angioplasty and number and location of stents needed to be implanted during the index procedure. Additionally, clinically driven target lesion revascularisation (CD-TLR) and major (above ankle) amputation rates were assessed during follow up. RESULTS A total of 180 patients were analysed who underwent antegrade (n = 90) or retrograde after failed antegrade (n = 90) recanalisation. The median patient age was 76.0 (interquartile range [IQR] 67.0, 82.0) years and 76 (42.2%) were female. Moreover, 78 patients (43.3%) had intermittent claudication, whereas 102 (56.7%) had chronic limb threatening ischaemia (CLTI). The mean lesion length was 30.0 (IQR 24.0, 36.0) cm with moderate to severe (3.0 [IQR 2.0, 4.0]) lesion calcification. Dissection severity after angioplasty was higher in the antegrade than retrograde after failed antegrade recanalisation group (4.0 [IQR 3.0, 4.0] vs. 3.0 [IQR 2.0, 4.0]; p < .001). Additionally, the number of stents in all segments and the rate of bailout stenting in popliteal segments was significantly higher with the antegrade strategy (2.0 [IQR 1.0, 3.0] vs. 1.0 [IQR 0, 2.0], p < .010; and 37% vs. 14%, p < .001). During a median follow up of 1.48 (IQR 0.63, 3.09) years, CD-TLR rates (p = .90) and amputation rates in patients with CLTI (p = .15) were not statistically significant. CONCLUSION In complex femoropopliteal CTOs, retrograde after failed antegrade recanalisation, is safe for endovascular revascularisation, which in experienced hands may result in less severe dissections and lower rates of stent placement. However, considering the relatively short follow up, CD-TLR and amputation rates were not statistically different between the two approaches. [German Clinical Trials Register: DRKS00015277.].

Abstract
INTRODUCTION The durability of hemodialysis vascular access remains a troublesome issue for the patients as well as vascular surgeons that requires frequent reinterventions to maintain the access function. AIM This study aimed to evaluate straight thigh polytetrafluethylene (PTFE) arteriovenous graft (AVG) in patients with exhausted upper extremities dialysis access. METHOD Our study was a retrospective analysis of prospectively collected data of 30 patients were operated upon for straight pattern lateral thigh PTFE AVG between 2016 and 2018. The primary outcome was efficacy and patency of AVG, and secondary outcome was procedure safety, including infection, thrombosis, ligation, lower limb functional status, and mortality. RESULTS A 30 patients with 30 Lower Limb AVG with maximum 30-month follow-up period. The mean age was 48 years. Males were (n = 15/30). Thrombophilia patients were (n = 7/30). Primary patency at 6 months was 100%. It declined to 93% at 12 months, 73% at 18 months, 47% at 24 months, and 40% at 30 months. The secondary patency was 97% at 18 months, 83% at 24 months, and 73% at 30 months. More than half of the patients showed complications (n = 18/30), the most frequent was thrombosis (n = 16/18). A secondary procedure was needed for 17 patients, the most frequent was thrombectomy (n = 11/17), adjunctive culprit lesion repair was the key for regaining graft patency. Graft removal was necessary in six patients due to infection (n = 4) and ruptured graft aneurysm (n = 2). CONCLUSION Lateral straight thigh PTFE AVG is a reliable and durable alternative modality with adequate dialysis efficacy in patients with exhausted upper extremities dialysis accesses. Secondary procedures due to complications were frequent but no significant major bleeding as regard patients with ruptured graft were non-significant and no distal threatening ischemia or related deaths were observed.

Abstract
BACKGROUND There appears to be an association between paclitaxel-coated devices and increased 5-year all-cause mortality. METHODS We are conducting a prospective, randomized, controlled, single-center, noninferiority study. All consecutive patients with femoropopliteal arterial disease who fulfilled the inclusion/exclusion criteria are sequentially and consecutively assigned to either paclitaxel (Ranger, Boston Scientific) or sirolimus (MagicTouch, Concept Medical) coated balloon angioplasty treatment. The primary outcome are procedural success and primary vessel patency at index procedure. The secondary outcomes are 30-day and 12-month freedom from MAEs (amputation, death, TLR/TVR, MI, distal embolization that requires a separate intervention or hospitalization), procedural success (≤30% residual diameter stenosis or occlusion after the procedure), Rutherford category improvement (reduction ≤1 category) and ABI improvement (increase ≥0.10 from baseline). RESULTS A total of six patients have been enrolled in the present study up to now. The mean age was 72.6 years old and five were male. All patients had angiographic evidence of isolated occlusion in the transition segment of the distal femoral superficial artery in the popliteal artery. The mean length was 109 mm. Three patients were treated by sirolimus-coated (group A) and three by paclitaxel coated balloon angioplasty (group B). The primary patency and procedural success was in two of three and three of three patients, for group A and B, respectively. CONCLUSIONS Preliminary results show safety and feasibility of the Sirolimus-coated balloon angioplasty. Further investigation and increase of sample size will allow for more sustained conclusions regarding patency and procedural success of this type of balloons for the endovascular treatment of peripheral arterial disease.

Abstract
BACKGROUND The purpose of this study was to define patient and anatomical factors associated with technical results specific to rotational atherectomy. Controversy exists surrounding appropriate utilization of atherectomy to treat femoral-popliteal atherosclerosis. Importantly, the existence of different atherectomy devices and lack of technical reports highlighting variables that impact outcomes obscures the ability to assess perioperative performance. METHODS The nonindustry sponsored, Multicentric National Registry on the use of rotational atherectomy in femoral-popliteal occlusive atherosclerotic disease (MORPHEAS) database was queried. The MORPHEAS investigators included experienced providers at four centers who previously had not utilized rotational atherectomy. The primary endpoint was flow-limiting dissection and/or >50% recoil resulting in stent-placement while a secondary endpoint included peripheral thromboembolism incidence. RESULTS One hundred thirteen patients were enrolled. Only femoropopliteal occlusions were included in the analysis and anatomic distribution and calcification severity were depicted separately. The most common adjunctive therapy was drug-coated balloon angioplasty (84%; N.=96). Flow-limiting dissection was identified in 16% (N.=18) and thromboembolism occurred in 4% (N.=4). Diabetes increased risk of thromboembolism (P=0.03) while lesion length ≥8.0 cm (P=0.07) and SFA-popliteal adductor canal location (P=0.01) were associated with flow-limiting dissection. In multivariable analysis, SFA-popliteal adductor canal occlusion had a 4.7-fold risk of perioperative complications (OR=4.7, 95%CI: 1.1-21.0; P=0.04). CONCLUSIONS Rotational atherectomy was characterized by reproducible performance among four centers; however, diabetic patients, as well as those with long-segment, heavily calcified SFA-popliteal adductor canal occlusion present greatest risk of complications.

Abstract
OBJECTIVE Peripheral artery disease (PAD) is often caused by atherosclerosis. However, causes other than atherosclerosis is often overlooked. Popliteal artery entrapment syndrome (PAES) and popliteal artery adventitial cystic disease (PACD) are two common nonatheromatous causes of claudication and critical limb ischemia. The purpose of this study is to present early results of treatment of PAES and PACD involving the lower limbs. METHODS From December 2019 to February 2021, 10 patients with PAES underwent surgeries, and 1 patient with PAES received conservative treatment. 2 patients with PACD underwent surgery. Patient data including age, gender, etiology of vascular pathology, diseased vessel, surgical method, and hemodynamic status were collected retrospectively. RESULTS The mean follow-up duration was 5.64 ± 3.72 months (range, 1-12 months). All patients had their symptoms improved or resolved. The success rate of surgery was 100%, the rate of freedom from reintervention for any reason was 100%. There were no death, bleeding, embolism, or skin ulcers during late follow-up. CONCLUSIONS PAES and PACD require early diagnosis and intervention, and early surgery may lead to good early- and mid-term results.

Abstract
OBJECTIVES Recent controversies on the use of drug coated/eluting devices in the arteries of the lower extremities renewed the focus on the evaluation of more conventional techniques. The results of the stenting of short and/or intermediate femoro-popliteal lesions are well known, but little data relate to the endovascular treatment of long femoro-popliteal lesions with contiguous bare metal stents (ETLFBS). The objective of this study was to report our results of ETLFBS. MATERIAL AND METHODS Between January 2014 and December 2017, 1233 patients had an infrainguinal angioplasty in our center. The files of patients treated for femoropopliteal lesions longer than 250 mm using extensive stenting with contiguous bare metal stents were reviewed and analyzed. The primary outcome was the 12-month primary patency, defined by the absence of restenosis (≥50%) and/or reintervention on the target lesion. Continuous data were expressed as mean and standard deviation. Survival analysis was carried out according to Kaplan-Meier. RESULTS Overall, 64 patients aged 80 ± 11 years were included, with 49 (76.6%) presenting with critical limb ischemia. Lesions were classified as TASC D in 54.7% of the cases. The length of the lesions was 295 ± 64 mm and 3 ± 1 stents were implanted. The 30-day mortality was null but two patients (3.1%) presented nonvascular major complications. With a follow-up of 27 ± 17 months, 22 patients (34.3%) died including three of vascular causes. The healing of the trophic disorder was obtained in 77.5% of the cases. The rate of amputation was 10.9%. The 6-, 12-, and 24-month primary patency rates were 79.7%, 66.6%, and 60.9%, respectively. The 6-, 12-, and 24-month rates of freedom from target lesion revascularization were 96.3%, 73.9%, and 71.9%, respectively. The 6-, 12-, and 24-month survival rates were 90.3%, 83.6%, and 65.6%, respectively. CONCLUSIONS The 12-month primary patency rate of ETLFBS is acceptable. This strategy constitutes an acceptable alternative in patients presenting with critical limb ischemia and a limited life expectancy.
