In-stent restenosis of drug-eluting stents in patients with diabetes mellitus: Clinical presentation, angiographic features, and outcomes.

Objective: Diabetes mellitus (DM) is a risk factor for developing in-stent restenosis (ISR) following percutaneous coronary intervention (PCI). This study aimed to examine the presentation and outcomes of drug-eluting stent (DES) ISR in diabetics.

Methods: This retrospective study included consecutive patients with clinical DES-ISR, who were hospitalized between January 2013 and December 2017 and who were grouped based on the presence or absence of DM.

Percutaneous intervention for restoration of patency of occluded lower limb arteriovenous dialysis access.

Background: Arteriovenous (AV) fistula thrombosis is a serious complication in patients undergoing hemodialysis, often presenting with symptoms of venous hypertension, failure to dialysis and uremic symptoms. Treatment is aimed to provide symptomatic relief and to maintain hemodialysis access site patency.

Aim: To describe our initial experience in the endovascular treatment of lower limb AV dialysis access (AV fistula) thrombosis and/or obstruction in patients undergoing hemodialysis.
