Acute aortoiliac and infrainguinal arterial thrombotic events in four patients diagnosed with the novel coronavirus 2019.

The novel coronavirus disease 2019 (COVID-19) pandemic is seriously challenging the healthcare system globally. Endothelial damage and increased coagulation activity have been reported in some patients with COVID-19, resulting in a variety of thrombotic events. We report the cases of four patients with various severities of COVID-19 who had presented with acute arterial thrombosis.

Femoral Access for Iliac Branched Endoprosthesis Deployment in Patients with a Prior Bifurcated Aortic Stent Graft.

This series describes an innovative technique to deploy iliac branched endoprostheses (IBEs) in patients with preexisting endovascular aneurysm repair (EVAR). It demonstrates an alternative approach that may be preferred when brachial access is anatomically challenging or when access site complications are of concern. We detail a technique that uses transfemoral access to bring IBE device components up and over an infrarenal endograft bifurcation and into proper position.

Preoperative inflammatory status as a predictor of primary patency after femoropopliteal stent implantation.

Objective: The purpose of this study was to evaluate the impact of preoperative inflammatory status, as determined by complete blood count test parameters, on 12- and 24-month patency of femoropopliteal stenting for peripheral arterial disease.

Methods: We retrospectively analyzed baseline clinical and angiographic data among 138 patients (median age, 73 years; 46% female) from 2005 to 2014 at our institution with preoperative complete blood count test values and information of patency for at least 12 months after first-time femoropopliteal stenting. Patients were stratified into tertiles on the basis of preoperative blood counts to evaluate associations with in-stent restenosis (ISR) leading to loss of primary patency, defined by a Doppler velocity ratio ≥2.

No major difference in outcomes for endovascular aneurysm repair stent grafts placed outside of instructions for use.

Objective: Studies have shown that a sizable percentage of endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms (AAAs) is performed outside the instructions for use (IFU). We report our long-term outcomes after EVAR with respect to device-specific IFU.

Methods: Computed tomography angiography data from a cohort of 566 patients meeting inclusion criteria who underwent elective EVAR between 2003 and 2014 were examined.
