A tapered stent with inclined proximal end is designed for fitting the iliac anatomically. The aim of the present study was to evaluate the safety and performance of the new stent in ovine left iliac veins. The experiment was performed in 30 adult sheep, and one nitinol-based VENA-BT iliac venous stent (KYD stent) was implanted into each animal's left common iliac vein.

The present study evaluated the prognosis of directional atherectomy (DA)+drug-coated balloon (DCB) angioplasty for femoropopliteal artery lesions compared with bare nitinol stent (BNS). This retrospective cohort study included patients with femoropopliteal artery lesions who underwent percutaneous endovascular surgery between January 2016 and June 2019. The primary outcome was the primary patency rate after 12, 24, and 36 months; the secondary outcomes comprised incidence of flow-limiting dissections, technical success, limb salvage, and all-cause death.

Background: Percutaneous transluminal angioplasty (PTA) has been the conventional therapy to infrapopliteal arterial occlusion. Lately, cool excimer laser-assisted angioplasty has been proposed to be the alternate methods. We performed a systematic review and meta-analysis of prospective and retrospective cohort studies and randomized controlled trials to assess the effect of cool excimer laser-assisted angioplasty vs.

Restenosis is the main restriction on the long-term efficacy of percutaneous transluminal angioplasty (PTA) therapy for peripheral artery disease (PAD). Interventions to prevent restenosis are poor, and the exact mechanism is unclear. Here, we aimed to elucidate the role of in the restenosis process post-PTA in lower extremity arteries.

Background: Dislocation of inferior vena cava filter (IVCF) is a rare complication with potential IVC perforation and other life-threatening risks requiring early diagnosis and in-time retrieval. Most of dislocation IVCF in the past have been shelved or removed by open surgery. It is very difficult to retrieve the filters by interventional technology.

The purpose of this article was to compare the efficiency and safety of drug-coated balloon angioplasty (DCB) and atherectomy with percutaneous transluminal angioplasty (PTA) in patients with femoropopliteal in-stent restenosis (ISR). Pubmed, Embase, and the Cochrane Central Register of Controlled Trials (CENTRAL) (all up to March 2019) were searched systematically. Trial sequential analysis (TSA) was conducted.

Background: The "leave nothing behind" strategies have been becoming a popular treatment for femoropopliteal arteriosclerosis obliterans. Atherectomy before drug-coated balloon (DCB) angioplasty may have an advantage in improving the efficiency of drug delivery into the blood vessel wall. This study aimed to compare the therapeutic effects of directional atherectomy combined with DCB angioplasty with DCB angioplasty alone in the treatment of femoropopliteal arteriosclerosis obliterans.

Background: Embolic superior mesenteric artery (SMA) occlusion is associated with high mortality rates. Delayed treatment often leads to serious consequences, including intestinal necrosis, resection, and even patient death. Endovascular repair is being introduced, which can improve clinical symptoms and prognosis and decrease the incidence of exploratory laparotomy.

Behçet's disease is a rare, chronic, relapsing condition comprising multisystemic inflammatory dysfunction, whereas subclavian artery aneurysm is a rare peripheral atherosclerotic aneurysm that has a high risk of rupture or embolization. Herein, we report the case of a 32-year-old man with Behçet's disease who developed pseudoaneurysm of the left subclavian artery. He was admitted to the emergency department due to radiating pain in the left neck and shoulder.

Background: Patients undergoing carotid artery stenosis who are prescribed aspirin, clopidogrel, or sarpogrelate as treatment options to inhibit platelet aggregation continues to increase. The purpose of this study was to compare the efficacy and safety of clopidogrel combined with aspirin (CA) versus sarpogrelate combined with aspirin (SA) treatment in carotid endarterectomy (CEA) patients.

Methods: This retrospective study included 197 CEA patients (mean age 61.

A 68-year-old female patient was treated for unhealed ulcer in the fourth toe of the left foot. Clinical examinations identified severe stenosis of the proximal segment and occlusion of the distal segment of the left anterior tibial artery, and occlusion of the left posterior tibial artery and the peroneal artery. The proximal stenotic segment of the left anterior tibial artery was dilated, but the distal occlusive part failed to be re-canalized.
