Background: Among patients with chronic limb-threatening ischemia (CLTI) and infrapopliteal artery disease, angioplasty has been associated with frequent reintervention and adverse limb outcomes from restenosis. The effect of the use of drug-eluting resorbable scaffolds on these outcomes remains unknown.
Methods: In this multicenter, randomized, controlled trial, 261 patients with CLTI and infrapopliteal artery disease were randomly assigned in a 2:1 ratio to receive treatment with an everolimus-eluting resorbable scaffold or angioplasty.

Background: Critical limb-threatening ischemia (CLTI) is a severe condition characterized by rest pain and ischemic tissue loss that affects 5% to 10% of people with peripheral artery disease. In the United States, there are few Food and Drug Administration-approved devices for the primary treatment of arteries below-the-knee (BTK). Unfortunately, all suffer from high restenosis rates due to intimal hyperplasia, elastic recoil, and untreated dissection because of a lack of scaffolding.

Vascular medicine specialists may help to bridge gaps in care, especially as part of multidisciplinary teams. However, there is a limited number of vascular medicine specialists because of constraints in training.

Veterinarians are most qualified to support local, state, national, and international efforts in emergency management. However, they may lack the knowledge and advanced training to most effectively plan, prepare, and respond.

However, stand-alone DCB use in long, severely calcified lesions is frequently associated with vessel recoil and/or high-grade dissections necessitating provisional stent implantation.
Objectives: Assess the safety and effectiveness of a vessel preparation strategy with directional atherectomy (DA) prior to DCB angioplasty in patients with symptomatic severely calcified femoropopliteal PAD.
Objectives: The authors analyzed data from the NCDR (National Cardiovascular Data Registry) PVI Registry and defined acute kidney injury (AKI) as increased creatinine of ≥0.3 mg/dl or 50%, or a new requirement for dialysis after PVI.
Background: AKI is an important and potentially modifiable complication of peripheral vascular intervention (PVI).
Isolated renal artery dissection (IRAD) is a rare and often unrecognized clinical entity, with a paucity of data on its epidemiology and management. We extracted 129 cases of IRAD from the medical literature between 1972 and 2016. IRAD as a result of an extended dissection from the aorta and splanchnic or mesenteric arteries was excluded.

Peripheral arterial calcification reduces acute success and long-term patency of endovascular therapy for PAD. Several calcium modification devices are available for use in peripheral interventions.

Isolated atherosclerotic lesions of the common femoral artery (CFA) are rare but can produce significant claudication and critical limb ischemia. To date, the "gold standard" treatment for this entity has been common femoral endarterectomy (CFE) with or without patch angioplasty. However, surgery does have significant early postoperative complications, with a 15% combined mortality/morbidity.

Background: Embolization is ubiquitous during endovascular procedures for lower extremity peripheral artery disease.
Methods: The WISE LE was a multicenter study, performed in the United States and Germany.
Objectives: To report on procedural, safety, and effectiveness outcomes of real-world practice with the Jetstream rotational atherectomy system for treatment of femoropopliteal artery lesions.
Background: Safety and effectiveness of treatment with the Jetstream device has been demonstrated in clinical trials, but outcomes during real-world clinical practice have yet to be examined.
Methods: 241 patients (66% male, mean age 67years, 41% diabetes; Rutherford 1-3) with de novo or restenotic (non-stent) femoropopliteal lesions ≥4cm in length were recruited.
Background: FDA approved the Gore Viabahn (WL Gore, Flagstaff, AZ, USA) stent for both femoro-popliteal arterial denovo and instent restenosis (ISRS) lesions. To date there is little data on Viabahn stent graft outcomes in ISRS arterial disease.
Methods: Between 2007 and 2014 we identified 734 patients who underwent 1573 endovascular interventions in our institution for infra-inguinal revascularization.
Purpose: To report the effectiveness of directional atherectomy for the treatment of popliteal artery occlusive disease.
Methods: This subset of the prospective, multicenter, single-arm DEFINITIVE LE trial included 158 patients (mean age 72.0±10.
Objectives: To propose a classification system for characterizing angiographic femoropopliteal artery restenosis patterns associated with common endovascular modalities.
Background: Peripheral artery disease is a worldwide issue affecting millions of people. Despite a myriad of endovascular technologies available to treat peripheral artery disease of the femoropopliteal arteries, restenosis remains a common failure mode.

Peripheral arterial disease (PAD) is a clinical manifestation of systemic atherosclerosis and is associated with significant morbidity and mortality. Vascular physicians come across PAD of different complexity and among them complex total occlusions present a formidable challenge to endovascular operators. Newer tools and techniques, particularly in the retrograde approach, have made endovascular therapy applicable to increasingly complex disease.

Importance: Long-term outcomes of an interwoven nitinol stent design represent the best in class for treatment of lower limb arterial obstructive disease METHODS: The subjects were enrolled in an open single arm study comparing the outcomes to an FDA mandated objective performance goal (OPG).
Results: About 325 patients (264 intention-to-treat and 64 roll-in subjects) were enrolled. Mean follow-up period was 887+/- 352 days.

Peripheral vascular disease (PVD) carries a significant morbidity and mortality. The role of inflammatory markers in cardiovascular medicine has been extensively studied. Neutrophil Lymphocyte ratio (NLR) is a novel biomarker which has been proposed as a marker of cardiovascular disease.

Methods: In the DEFINITIVE LE trial, follow-up assessments occurred up to 1 year postprocedure. Of the 800 patients enrolled, 145 subjects with 189 infrapopliteal lesions met the criteria for this analysis.
We report the case of a 66-year-old woman who developed acute kidney allograft failure due to thrombotic occlusion of the common iliac artery after hysterectomy requiring emergent allograft rescue. She underwent percutaneous transluminal angioplasty with endovascular balloon expandable covered stent graft placement in the right common iliac artery. Although there are a handful of case reports of acute limb ischemia secondary to acute common iliac artery thrombosis, this is the first case reported in the literature resulting in successful kidney allograft rescue following pelvic surgery.

Methods: DEFINITIVE LE, a US/European multicenter study, assessed the effectiveness of directional atherectomy using SilverHawk/TurboHawk systems for treatment of peripheral artery disease in the superficial femoral, popliteal, and infrapopliteal arteries. Of the 800 patients enrolled in the study, only the 598 claudicant patients (mean age 69.
