Objective:To evaluate the difference in perioperative conditions of open surgery and endovascular repair for abdominal aortic aneurysm in China.
Methods:Articles of non-randomized comparative studies(NRCs) of open surgical repair and endovascular repair for abdominal aortic aneurysm which were published in china before January 2009 were retrieved, and correlated indexes were extracted for meta-analysis.
Results:The mean quality score of the 6 articles selected was 18.83±0.98. Compared with open surgical repair, the endovascular repair was associated with a significantly less amount of blood loss (WMD=-689.24   mL,95%CI:-1077.61～-300.88,P＜0.05),less blood transfusion(WMD=-440.01 mL,95%CI:-488.96～-391.06,P＜0.05）during the operation, shorter time of fasting period(WMD=-5.21 d,95%CI:-6.23～-4.19,P＜0.05),shorter observation period in intensive care unit(WMD=-1.79 d,95%CI:-2.21～-1.46,P＜0.05) and shorter hospital stay after operation(WMD=-5.19 d,95%CI:-7.09～-3.28,P＜0.05). There was no statistically significant difference in operative time（WMD=-35.86 min,95%CI:-85.01～13.28,P=0.15） or complication rate(OR=0.92,95%CI:0.55～1.53,P=0.74)between the two groups.
Conclusions:The results of meta-analysis show that endovascular repair has the advantage of mild trauma, less blood loss and quicker recovery after operation. But there was no significant difference in operative time and complication rate between the two groups.
