Endovascular versus open repair for ruptured abdominal aortic aneurysm

Objective To compare the effect after endovascular repair (EVAR) or open repair (OR) of ruptured abdominal aortic aneurysm (rAAA) in Department of Vascular Surgery, Beijing Anzhen Hospital. Methods Clinical data of 46 repaired rAAAs patients was retrospectively analyzed from 2005 to 2015. The difference between the EVAR group and the OR group in perioperative mortality, operation time, ICU stay, blood transfused, length of stay(LOS), complication rate were compared by χ2 test and t test. Results 18 rAAA patients were repaired by EVAR, aged from 51 to 91 with a mean of (68±9).28 were repaired by OR, aged from 41 to 83 with a mean of (70±11). Perioperative mortality was 21.0% for EVAR and 28.6% for OR (P>0.05). LOS was (15.3±9.5) days for EVAR, and (23.9±10.5) days for OR (P<0.05). Blood transfused was (3 210±3 780) ml for EVAR and (4 814±3 392) ml for OR (P<0.05). ICU stay time was (7.7±4.2) d for EVAR and (4.2±2.5) d for OR (P<0.05). Conclusion EVAR is a reliable approach for the treatment of acute rAAA. Key words: Aortic aneurysm, abdominal; Endovascular repair; Open surgery; Treatment outcome
