BACKGROUND: Previous reports have revealed various endovascular intervention techniques for prosthetic femoropopliteal bypass occlusion (PFPBO); however, treatment for PFPBO remains challenging for most interventionalists and vascular surgeons because the procedure is complicated. Most of the reported techniques involve device implantation. In the present study, we performed a combination of surgical graft thrombectomy and drug-coated balloon angioplasty for PFPBO without implanting any additional devices...

BACKGROUND: In recent years, endovascular treatment has emerged as a preferred option for treating long lesions in the superficial femoral artery (SFA), including those classified as Trans-Atlantic Inter-Society Consensus IIC and D. This approach may involve the use of multiple stents to ensure adequate coverage of the entire lesion, as maintaining primary patency is a key consideration in the treatment strategy. CASE SUMMARY: An 82-year-old woman underwent endovascular treatment with two stents for a chronic total occlusion lesion in the left SFA...

A 57-year-old woman with critical limb-threatening ischemia (CLTI) of the left lower leg underwent endovascular therapy. She had undergone a femoropopliteal (F-P) bypass for treatment of chronic total occlusion (CTO) of the superficial femoral artery (SFA) four years prior.

OBJECTIVE: True superficial femoral artery aneurysms (SFAAs) are rare and traditionally treated by open repair. However, the endovascular approach excluding the aneurysm sac with a covered stent may be an alternative. This study aimed to compare the outcomes of the open and endovascular repair of SFAAs. METHODS: This is a retrospective, observational, monocentric study. The main endpoints were: technical success, limb salvage and primary patency rate, and hospitalisation time...

PURPOSE: To describe a technique in which two 5-F curved catheters were utilized to facilitate the wire-catheter approach for recanalizing chronic total occlusions (CTOs) in the iliac arteries concurrently affecting the common iliac artery and external iliac artery. METHODS: This was a single-center retrospective analysis involving endovascular recanalization of 17 iliac artery CTOs in 15 patients (mean age: 73.66 years; all men) between January 2019 and October 2022 using the subintimal arterial flossing with antegrade-retrograde intervention technique...

OBJECTIVE: We describe the technique and early results of lower extremity revascularization with total percutaneous bypass using extravascular placement of a stent graft (percutaneous prosthetic bypass). METHODS: Patients with severe chronic limb threatening ischemia for whom open or endoluminal repair was either not feasible and or had failed were selected for a pilot study using percutaneous prosthetic bypass. The procedure requires placement of three introducer sheaths in the contralateral common femoral artery, and the ipsilateral proximal and distal superficial femoral arteries (SFAs)...

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...

Femoropopliteal disease comprises more than one half of lesions in peripheral vascular disease. The treatment modalities for stenosis or occlusion of this anatomic region include femoropopliteal bypass and percutaneous transluminal angioplasty with or without stenting. Our patient developed acute leg ischemia 3 years after stenting, secondary to stent fracture, with distal embolization of stent fragments. Using mechanical thromboembolectomy and superficial femoral artery to below-the-knee popliteal in situ saphenous vein bypass, we were able to restore perfusion to the limb and retrieve fragments of the fractured stent...

Intermittent claudication (IC) from peripheral arterial disease is typically managed with pharmacologic interventions and lifestyle changes. However, despite societal guidelines, initial endovascular interventions are being used more frequently with an increased incidence of complications, resulting in rapid disease progression to critical and acute limb-threatening ischemia (ALI). The present report describes the case of a patient who developed ALI after treatment of IC at another facility, with malpositioned bilateral common iliac stents, continuous stent extension into the popliteal artery, and acute occlusion of the entirety of the right lower extremity vasculature...

OBJECTIVE: Indications for endovascular treatment of femoropopliteal (FP) lesions have steadily increased over the past decade. Accordingly, the number of devices has also increased but the choice of the best endovascular treatment remains to be defined. The aim of this meta-analysis was to summarize all studies investigating endovascular treatment of FP lesions greater than 150 mm from 2010 to 2021. METHODS: Articles were searched using PubMed, Scopus, and Cochrane...

Minimally invasive treatment of severe aortic stenosis by transcatheter aortic valve replacement (TAVR) and infrarenal abdominal aortic aneurysm by endovascular aortic aneurysm repair (EVAR) requires large-bore vascular access. These percutaneous transfemoral interventions may be performed as a combined procedure, however, vascular injury may necessitate surgical vascular repair. We implemented a strategy designed to enable percutaneous vascular repair, with stent-graft implantation, if necessary, after these combined procedures...

OBJECTIVE: Superficial femoral artery stenting is a common treatment for peripheral artery disease. It is effective in the short term, however in-stent restenosis limits long term success. Surveillance with duplex ultrasound can identify patients who develop in-stent restenosis leading to early reintervention, but data to support this practice is sparce. The purpose of this study was to evaluate whether surveillance and subsequent reintervention improves outcomes in patients with SFA stents...

BACKGROUND: Though fracture is known complication of stenting, pseudoaneurysm asscoiated with stent fracture is an extremely rare complication. This has previoulsy been described to occur at least one or more years following initial stent placement. Here we present a case of multi-site stent fracture leading to two separate SFA pseudoaneurysms within one year of placement, successfully treated with covered stents. CASE PRESENTATION: A 72-year-old male presented with severe claudication of his left lower extremity (Rutherford 3), found to have long segment SFA chronic total occlusion (CTO)...

BACKGROUND: The Bard LifeStent® self-expanding stent is approved for the treatment of occlusive disease involving the superficial femoral artery (SFA) and proximal popliteal artery. We conducted a post-market trial of treatment of the popliteal artery above and below the knee (P1,P2 and P3 segments) within the Society for Vascular Surgery (SVS) Vascular Quality Initiative (VQI) Peripheral Vascular Intervention (PVI) registry. METHODS: A single arm, prospective trial was conducted at 29 VQI sites in the United States enrolling 74 patients from November 2016 to May 2019...

INTRODUCTION: PAD frequently co-occurs with diabetes, often leading to chronic nonhealing wounds. Foot gangrene and amputation are common outcomes of untreated CLI. CASE REPORT: A 67-year-old male with diabetes and deteriorating limb ischemia following surgical stress underwent successful surgical repair after emergency PTA of the SFA for extensive heel necrosis. After surgical debridement of necrotic heel tissue, the ABI on the affected side suddenly reduced to 0...

BACKGROUND AND AIMS: Polymer-coated drug-eluting stents (Eluvia) have shown favorable clinical outcomes in real-world registries. There are no reports on recurrent predictors after Eluvia placement based on intravascular ultrasound (IVUS) findings. METHODS: We analyzed clinical data from the ASIGARU PAD registry, a retrospective, multicenter, observational study that enrolled patients who underwent endovascular therapy for superficial femoral and proximal popliteal arteries lesions using Eluvia or drug-coated balloon...

PURPOSE: To investigate the one- and two-year clinical outcomes of Supera (Abbott Laboratories, IL, USA) interwoven stent (IWS) implantation for symptomatic femoropopliteal arterial disease with calcification. MATERIAL AND METHODS: This prospective multicenter study evaluated 308 limbs (63% with the peripheral arterial calcium scoring system [PACCS] 3 and 4 severe calcification, and 87% with ≥180° calcification on intravascular ultrasound) of 299 patients (diabetes in 66...

OBJECTIVE: Peripheral arterial stenoses (PAS) are commonly investigated with duplex ultrasound (DUS) and angiography, but these are not functional tests. Fractional flow reserve (FFR), a pressure based index, functionally assesses the ischaemic potential of coronary stenoses, but its utility in PAS is unknown. FFR in the peripheral vasculature in patients with limb ischaemia was investigated. METHODS: Patients scheduled for angioplasty/stenting of isolated iliac and superficial femoral artery stenoses were recruited...

PURPOSE: Clinical trials have demonstrated the superiority of drug-coated balloon (DCB) to noncoated balloon angioplasty for the treatment of femoropopliteal (FP) lesions. In those trials, the difference of primary patency between DCB and noncoated angioplasty widens especially after 6 months, speculating that the antirestenosis effect of paclitaxel is manifested after 6 months. Factors associated with restenosis after 6 months differ from those associated with restenosis within 6 months...
