Abstract
BACKGROUND: Given the various types of anesthesia used for endovascular abdominal aortic aneurysm repair (EVAR), we sought to determine the effect of anesthesia type in the outcomes of elective EVAR in a large multiinstitutional healthcare maintenance organization. METHODS: A retrospective chart review was conducted on all elective EVAR conducted from August 2010 to August 2017 in 14 regional hospitals of Kaiser Permanente Southern California. Patients undergoing emergent, nonelective abdominal aortic aneurysm repairs, thoracoabdominal aneurysm repair, requiring conversion to open surgery or general anesthesia were excluded from the study. Basic demographic information, medical risk factors, anesthesia type, operative data, and postoperative morbidity and mortality data were obtained for univariate and multivariate statistical analysis. RESULTS: A total of 1,536 patients underwent EVAR, of which 1,206 met inclusion criteria. A total of 788 patients underwent general anesthesia, 164 patients underwent spinal anesthesia, 82 patients underwent epidural anesthesia, and 172 patients underwent local and monitored anesthesia care (AC). There was a significant difference in length of stay and operative time when comparing local/monitored AC to general anesthesia. No significant difference was noted in 30-day morbidity or mortality among the anesthesia groups. CONCLUSIONS: Local and regional anesthesia is a safe and effective approach for elective EVAR.
