Stent thrombosis is a feared complication of percutaneous coronary intervention due to its catastrophic consequences. We analysed the incidence of angiographically-confirmed thrombosis in 5011 consecutive patients treated with drug-eluting stents or bare-metal stents. Although the incidence of thrombosis was similar between the two groups (0.8%), angiographically-documented late thrombosis was a relatively unusual complication after implantation of either stent, though it was more common with drug-eluting stents than bare-metal stents (0.25 vs. 0.06%, P=.03).

Aim This study aims to evaluate the safety and efficacy of transjugular intrahepatic portosystemic shunt (TIPS) check and revision procedures performed in a freestanding interventional radiology (IR) outpatient facility. Methodology A total of 40 patients (male 31:female 9, median age 60 years old) underwent a TIPS check and/or revision at a freestanding IR outpatient facility between 2009 and 2017. Procedures were performed using a mobile C-arm unit under intravenous (IV) moderate sedation, with the patient discharged home on the same day.

: Contemporary treatments of acute aortic dissection, including medical, surgical, and endovascular options, are remarkably effective at the management of malperfusion and rupture. Unfortunately, long-term studies indicate that 30%-50% of patients need secondary procedures to treat progressive aneurysmal enlargement of the untreated aorta. The Stent-assisted balloon-induced intimal disruption and relamination in aortic dissection repair (STABILISE) technique was introduced to improve long-term outcomes.

The growing prevalence of coronary artery diseases in the US corresponds to the increasing use of minimally invasive techniques that require coronary stents. Although extensive research is available on the perioperative outcomes of the 3 stent options - bare-metal stents (BMS), drug-eluting stents (DES), and bioresorbable drug-eluting stents (BVS), a knowledge gap exists in the longitudinal monitoring of patient outcomes due to device-related causes. Therefore, our study examines the device-related patient outcome and the relative performance for BMS, DES, and BVS.

Background: To compare the performance of a new-generation cobalt-chromium balloon-expandable bare metal stent with a stainless steel platform for the treatment of iliac occlusive disease.

Methods: Consecutive patients treated for symptomatic iliac occlusive disease between 2014 and 2021 with the cobalt-chromium Dynetic-35 or the stainless steel Dynamic platform were retrospectively evaluated. Outcome measures included technical success, device- or procedure-related death, clinically-driven target lesion revascularization (CD-TLR), primary patency, and major index limb amputation up to 12 months.

Background: The risk of limb graft occlusion (LGO) after endovascular aneurysm repair (EVAR) is increased by severe tortuosity of the iliac artery. A bare metal stent (BMS) may protect LGO, according to the hypothesis of this single-center retrospective analysis.

Methods: All patients undergoing elective EVAR with a bifurcated stent graft between January 2012 and June 2022 were included in this cohort study.
