Mid-term comparison of bifurcated modular endograft versus aorto-uni-iliac endograft in patients with abdominal aortic aneurysm.

The aim of this prospective study was to compare the outcome of the Talent bifurcated endograft versus the Endofit aorto-uni-iliac endograft in the short-term and mid-term. Between March 2000 and December 2003, 86 patients were treated with the Talent bifurcated endograft (group A) and 21 with the Endofit aorto-uni-iliac endograft (group B) in the same institute by the same surgical team. All patients followed a prospective protocol of preoperative evaluation and postoperative follow-up. We compared groups A and B in terms of perioperative mortality and morbidity, mid-term endoleak rate, mid-term success rate, and mid-term survival. The perioperative mortality for group A was 1.63%, while that for group B was 0% (P = 0.62). The endoleak rate for group A was 4.65%, and that for group B was 14.29% (P = 0.135). The mid-term success rate was 96.5% for group A and 100% for group B (P = 0.386). There was no significant difference in outcome between the patients treated with the Talent and those treated with the Endofit endoprosthesis. Treating abdominal aortic aneurysms with aorto-uni-iliac endoprosthesis is as safe and effective as treating them with bifurcated endografts.
