Abstract

General anesthesia (GA) and locoregional anesthesia (LA) are two anesthetic options for endovascular repair of ruptured abdominal aortic aneurysms (REVAR). Studies on elective endovascular repair of nonruptured aneurysms have indicated that in select patients, LA may provide improved outcomes compared with GA. We aimed to examine the 30-day outcomes in patients undergoing REVAR using GA and LA in a contemporary nationwide cohort of patients presenting with ruptured abdominal aortic aneurysms. Patients who underwent REVAR using GA and LA from January 2011 through December 2015, inclusively, were studied in the American College of Surgeons' National Surgical Quality Improvement Program (ACS NSQIP)-targeted EVAR database. Univariate and multivariate analyses were used to compare preoperative demographics, operation-specific variables, and 30-day postoperative outcomes between the two groups. Six-hundred ninety patients were identified to have undergone REVAR from 2011 to 2015, of which 12.5% (86) were performed under LA. For the entire cohort, the mean age was 74.3 years, and 80% were male. Mean aneurysm size was 7.6 cm and did not differ between the two anesthetic groups. Major comorbidities were similar between both groups, exce...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.

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.

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.
