[Comparison of open and endovascular repair for abdominal aortic aneurysm]

To compare the effects of open and endovascular repair for abdominal aortic aneurysm.

From January 2002 to July 2007, clinical data of 223 patients with infrarenal abdominal aortic aneurysm undergoing open (141 patients) or endovascular repair (82 patients) were retrospectively reviewed. The intra- and post-operative complications, mortality, complications, survival, life quality, and cost during follow-up were analyzed.

Operative time in endovascular group was significantly shorter than open repair group. Blood loss and transfusion in endovascular group were significantly less than open repair group (P < 0.01). There was no significant difference of intra- and post-operation complications (P > 0.05). Six-month total SF-36 scores were significantly higher in open repair group compared with endovascular group. There was no significant difference of survival rate at 2 years (P > 0.05), but endovascular group had fewer complications (P < 0.01).

Endovascular repair is mini-invasive, but has more complications of long-term follow-up. The life quality in open repair group is better than endovascular group, and a prospective random trial is required.
