Abstract

The mortality of ruptured abdominal aortic aneurysm (rAAA) has decreased 3.5% per decade in the last 50 years to a current rate of 40%-50%. Reports have indicated that endovascular repair (EVAR) is feasible for rAAA and may offer potential benefits over open repair. We examined the National Surgical Quality Improvement Program (NSQIP) database to compare 30-day multicenter outcomes for EVAR vs open rAAA repair. Patients that underwent rAAA repair in the NSQIP database from 2005 to 2007 were identified through a combination of Current Procedural Terminology (CPT) codes and International Classification of Diseases-Ninth Revision (ICD-9) diagnoses. Preoperative comorbidities, operative duration and transfusion, and 30 day outcomes were evaluated using t tests or Chi-squared tests depending on the variable. A separate multivariable regression was performed for each outcome adjusting for all independently predictive preoperative and intraoperative risk factors. A total of 427 patients were identified and 76.8% of patients underwent open repair. The open repair groups exhibited lower albumin levels and higher percentage of patients with preoperative hematocrit (Hct) <38% and need for preoperative ventilation. The requirement for preo...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.
