Abstract

Outcomes following transcatheter interventions at vascular and general surgery teaching hospitals (STH) are unknown. We examine whether surgery training programs influence clinically relevant outcomes after commonly performed endovascular procedures. Using an all-payer inpatient care database from 2008, we selected adults who underwent either endovascular carotid stenting, endografting of descending thoracic aortic aneurysm, endovascular abdominal aortic aneurysm repair, or peripheral arterial revascularization. Patients were stratified by procedures completed at Surgery Teaching (Participate in Accreditation Council for Graduate Medical Education [ACGME]-accredited vascular and general surgery programs), STH, or nonteaching hospitals (NTH). Hierarchical regression models assessed adverse outcomes and in-hospital mortality among groups. Of the 175,698 records, 44% of the patients were treated at STH, while 56% underwent procedures at NTH. The adjusted odds ratio of any complication or mortality at STH and NTH were similar. Transfers, weekend admissions, and nonelective cases were higher at STH (P < .001, respectively). Paradoxically, STH treated fewer patients with more than three comorbidities compared with NTH (STH: 47% vs NT...Continue Reading

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.
