Abstract
BACKGROUND: The American College of Surgeons' National Quality Improvement Program (NSQIP) database can be used to assess trends and outcomes of ruptured abdominal aortic aneurysm (rAAA) repair. The purpose of this study is to examine the morbidity and mortality for ruptured endovascular (rEVAR) and ruptured open (rOPEN) aneurysm repair compared with elective endovascular (EVAR) and elective open (OPEN) aneurysm repair. METHODS: Ruptured and nonruptured abdominal aortic aneurysms were identified from the NSQIP database between 2008 and 2016. Data regarding demographics and comorbidities, 30-day mortality, and postoperative complications were collected for rEVAR, rOPEN, EVAR, and OPEN cases. RESULTS: There were 43,105 AAAs, 34,177 (79.28%) EVARs, and 8928 (20.71%) OPENs. There were 3806 rAAAs, 1843 (48.42%) rEVARs, and 1963 (51.58%) rOPENs. The incidence of rEVAR repair lagged behind EVAR considerably. Mortality for rOPEN was 575 (29.29%) and 344 (18.66%) for rEVAR. No difference between the ratio of men to women in rOPEN vs rEVAR was noted. There was a significant increase in mortality for women vs men undergoing rEVAR (P = .0362). No difference in mortality existed between women vs men undergoing rOPEN (P = .0639). There was no difference in the percentage of hypotensive cases undergoing rEVAR vs rOPEN (P =.1873). For all rAAAs with hypotension, rOPEN had an increased mortality compared to rEVAR (P = .0004). There were 20 (3.11%) rEVAR and 40 (8.00%) rOPEN cases with lower extremity ischemia. rOPEN conferred a significant increase in lower extremity ischemia (P = .0002). There were 46 (7.15%) rEVAR and 60 (12.00%) rOPEN cases of ischemic colitis. rOPEN had a significant increase in ischemic colitis (P = .0052). CONCLUSIONS: NSQIP data, over 9 years, demonstrate an increased morbidity and mortality associated with open vs endovascular repair of rAAAs. A great disparity exists between the proportion of rEVAR and rOPEN to EVAR and OPEN. The lagging use of endovascular repair of rAAAs must be further explored.
