This multicenter retrospective study assessed the clinical outcomes of endovascular therapy (EVT) using a drug-coated balloon (DCB) that was larger than the predilatation balloons for femoropopliteal artery lesions. We analyzed 1140 cases with symptomatic peripheral artery disease that underwent EVT with DCB for femoropopliteal lesions between 2017 and 2021. The primary endpoint was procedural failure, defined as a composite of deteriorated dissection and bailout stenting. The secondary endpoints included deteriorated dissection, bailout stenting, restenosis, and target lesion revascularization...

OBJECTIVE: In two randomized controlled trials, the outcomes of endovascular treatment of complex femoropopliteal arterial lesions were compared with bypass surgery and considered a valid alternative treatment. The aim of this study was to compare both endovascular treatment options with the hypothesis that implantation of heparin-bonded self-expanding covered stents (Viabahn, SECS) or drug-eluting stents (ZilverPTX, DES) are related to similar clinical outcomes at one-year follow-up...

Background: Endovascular techniques have gained preference over peripheral arterial bypass surgery due to their minimally invasive nature; however, endovascular treatments often show limited efficacy in arterial segments with a high atherosclerotic load. The use of atherectomy devices enables the removal of calcified plaque material and may promote arterial wall remodeling. This study assessed the technical success, safety, and feasibility of the BYCROSS® atherectomy device in femoropopliteal lesions. Methods: This single-center, retrospective cohort study analyzed elective patients undergoing BYCROSS® atherectomy for chronic peripheral arterial disease from March 2022 to May 2023...

KEY CLINICAL MESSAGE: The presence of multiple pseudoaneurysms in a patient should prompt investigations for the underlying etiologies including autoimmune and immunosuppressive disease processes. Treatment options include open repair and endovascular stenting. ABSTRACT: Pseudoaneurysms (also known as false aneurysms) are atypical dilatations or outpouchings from a vessel which are not always contained by the three layers of a normal vessel wall, namely the intima, media, and adventitia...

INTRODUCTION: Lower extremity angiography is one of the most prevalent vascular procedures performed, generally via the contralateral common femoral artery. The use of retrograde pedal artery access to perform angiography has long been reserved as a "bail-out" technique to help cross chronic total occlusions that were not amenable from an antegrade approach. Recently, there has been reports and discussion involving increased utilization of pedal access for primary revascularization. The purpose of this study is to describe the outcomes of pedal access as a primary approach and to propose a novel evaluation of distal perfusion changes associated with interventions using direct pressure measurements...

OBJECTIVES: The study compared the outcomes between covered-stents grafting (CSG) and ligation of femoral artery (LFA) in the treatment of infected femoral pseudoaneurysm (IFP) caused by intravenous drug injection. METHODS: From 1st January 2016 to 30th November 2021, the clinical data of patients with IFP caused by intravenous drug injection who underwent CSG ( n = 31, 55.4%) and LFA ( n = 25, 45.4%) are retrospectively analyzed. We compared the baseline characteristics and clinical outcomes of the two groups, including early and late mortality and morbidity...

This study aimed to compare lower limb events associated with preplanned and finally selected treatment strategies-the validity and usefulness of the physician-chosen strategy were verified.We examined the data of 1003 patients in the registry of multicenter endovascular treatment for superficial femoral and popliteal artery disease study and prospectively enrolled patients who underwent endovascular treatment (EVT) of the femoropopliteal (FP) artery between February 2017 and June 2018 from 67 Japanese institutes...

OBJECTIVE: To compare the short-term and long-term outcomes of hybrid interventions after various infrainguinal reconstructions (restoration of blood flow through superficial femoral artery and pulsatile blood flow through deep femoral artery) in patients with iliac-femoral arterial disease. MATERIAL AND METHODS: A retrospective analysis included patients after hybrid iliac-femoral interventions between 2014 and 2018. These interventions included stenting of iliac arteries and various open infrainguinal reconstructions...

OBJECTIVE: The study aimed was to report 2-year outcomes of endovascular treatment with interwoven nitinol (Supera™) stent for common femoral artery (CFA) lesions. METHODS: We reviewed the clinical data of 20 patients who presented with CFA stenosis or occlusion and underwent balloon angioplasty followed by Supera™ stenting in CFA between February 2016 and January 2022. The outcomes were evaluated in these patients in terms of technical success, post-intervention complications, reintervention, and cumulative patency (1 year, and 2 years)...

Arteriovenous fistula (AVF) formation after penetrating injury underscores a rare and challenging complication of vascular trauma. Traumatic AVFs have various clinical presentations and reported methods of repair. Although open surgical repair is the most frequently used method of repair, the advancement of endovascular techniques has been increasingly used during the past 3 decades. We report a case of an acute traumatic AVF of the superficial femoral artery and superficial femoral vein from a gunshot wound repaired with a unique endovascular technique involving snaring to establish through-and-through access to allow deployment of a covered stent graft...

PURPOSE: Surgical thromboendarterectomy has been the gold standard treatment for common femoral artery (CFA) disease. However, endovascular therapy (EVT) is conducted in certain patients with CFA lesions because of multiple comorbidities. The interwoven nitinol stent (IWS) has been developed to prevent stent fracture. Thus, this study aimed to evaluate the feasibility of EVT using IWS for CFA lesions in clinical practice. MATERIALS AND METHODS: This retrospective multicenter registry analyzed patients who had symptomatic lower-extremity artery disease due to CFA lesions and underwent EVT using IWS between 2019 and 2021...

The patient received endovascular therapy for a superficial femoral artery occlusion. Placement of a SMART stent distal to the lesion was successful, but deployment issues occurred with the Innova stent, requiring forceful retraction and causing elongation. The "cut and peel technique" was developed as a bailout strategy for such cases.

OBJECTIVE: This study aims to compare the 5-year outcomes of endoluminal bypass (EB) using heparin-bonded self-expanding covered stents versus bypass surgery for extensive femoropopliteal disease, including technical and clinical outcomes and health status. BACKGROUND: The surgical femoropopliteal bypass was the gold standard to treat peripheral arterial disease (PAD) for decades; however, endovascular treatment modalities are now recommended for most femoropopliteal lesions...

BACKGROUND: The treatment of complex infra-inguinal disease with drug-coated balloons (DCBs) is associated with a significant number of patients undergoing provisional stenting to treat a suboptimal result. To determine the potential long-term impact of DCB treatment with provisional bare metal stenting in complex lesions in real-world patients, a post hoc analysis was performed on data from the IN.PACT Global Study (The IN.PACT Global Clinical Study for the Treatment of Comprehensive Superficial Femoral and/or Popliteal Artery Lesions Using the IN...

Entrapment of devices, such as a Rota bar, an extension catheter, or an intravascular ultrasound device, during percutaneous coronary intervention has been reported and bailout strategies have been discussed. However, there have been few reports on entrapment of devices during endovascular treatment (EVT). A 70-year-old man was referred to our clinic for the management of rest pain in his left lower limb. His left ankle-brachial index was unmeasurable and computed tomography angiography revealed total occlusion of the left common, external iliac, and superficial femoral arteries (SFA)...

PURPOSE: This follow-up study was designed as a reopen of the completed Freeway Stent Study and collected mortality and clinical outcome data for at least 5 years after enrollment to evaluate long-term patient safety and treatment efficacy. The primary study enrolled 204 patients with stenosis or occlusion in the superficial femoral artery and proximal popliteal artery. Patients were randomized to primary nitinol stenting followed by standard PTA or primary nitinol stenting followed by FREEWAY™ paclitaxel-eluting balloon PTA...

OBJECTIVE: To report the results of a prospective, single-arm, registry-based study assessing the safety and performance of a paclitaxel drug-coated balloon (DCB) for the treatment of superficial femoral artery (SFA) or popliteal artery in-stent restenosis (ISR) in a United States population. METHODS: We conducted a prospective, non-randomized, multi-center, single-arm, post-market registry of the IN.PACT Admiral DCB for the treatment of ISR lesions in the SFA or popliteal artery at 43 sites within the Society for Vascular Surgery (SVS) Vascular Quality Initiative (VQI) Registry from December 2016 to January 2020...

OBJECTIVE: We evaluated the midterm results of atherectomy-assisted angioplasty for the treatment of femoropopliteal lesions and the identification of possible subgroups of patients with superior outcomes. METHODS: We conducted a single-center, physician-initiated, nonindustry-sponsored retrospective analysis of patients with Rutherford category ranging from II to V and de novo occlusive or stenotic lesions of the superficial femoral (SFA) and/or popliteal arteries treated with atherectomy-assisted angioplasty (Jetstream rotational atherectomy + drug-eluting ballooning)...

BACKGROUND: Hydrophilic polymer gel coatings are used on different intravascular devices to prevent vasospasm and thrombosis. However, it may become dislodged from these devices, leading to ischaemic complications in various organs including the skin, kidneys, brain, heart or lungs. Hydrophilic polymer embolisation (HPE) is a rare complication following endovascular procedures that is currently not fully recognised. The current knowledge of this phenomenon is based on reports consisting of histologic evidence of foreign polymers in the affected organ...

PURPOSE: To evaluate the potential differences in characteristics of femoropopliteal in-stent restenosis (ISR) stratified by stent design with a focus on the swirling flow-inducing BioMimics 3D helical centerline stent. METHODS: Patients with ISR of the superficial femoral and popliteal arteries undergoing reintervention were included in this study. The primary endpoint was the angiographic localization and extent of restenosis or reocclusion with the following five different stent systems: SMART Control stent, Supera peripheral stent, GORE® VIABAHN® endoprosthesis, BioMimics 3D stent, and Zilver® PTX® stent...
