Neurologic Complications after Abdominal Aortic Aneurysm Repair: a Comparison between Endovascular and Open Procedure. (P4.157)

OBJECTIVE/ BACKGROUND: Abdominal aortic aneurysm (AAA) repairs may be completed through either an open or endovascular approach. Endovascular repair has become more common, over 70[percnt] of the procedures currently done. Despite acceptance of endovascular repair as the ‘first-line’ treatment for AAA, there is limited data on neurologic complications following these interventions. The incidence of neurologic complications in the immediate 30 days following AAA repair was investigated. Mortality and incidence of neurologic complications in those with prior neurologic comorbidities and in those receiving emergent repair was also studied. DESIGN/METHODS: The American College of Surgeons National Surgical Quality Improvement Program Participant Data File was analyzed, including all vascular surgeries for AAA repair, 2009-2010. Neurologic complications in the first 30-days postoperative were investigated, including cerebrovascular accident, coma, and peripheral nerve injury as well as total neurologic complications and RESULTS: AAA repairs (n=6,921), were investigated during 2009-2010, with prevalence of men to women, 4.5:1. Neurologic complications were significantly higher postoperatively in open versus endovascular repair, with significant differences in number of cerebrovascular accidents (x 2 =16.95; p 2 =27.15; p 2 =823.59; p 2 =196.29; p 2 =6.2918; p=0.012). CONCLUSIONS: These findings clearly demonstrate that the endovascular approach is safer than the open repair, with less short-term, 30-day post-operative neurological complications and mortality.
