Aorto-uni-iliac endograft for complex aortoiliac aneurysms compared with tube/bifurcation endografts: Results of the EVT/Guidant trials

Abstract

Objective: Our objective was to present the results of the multicenter EVT/Guidant aorto-uni-iliac trial and to compare them with the tube, bifurcated graft, and open control series in regard to patient demographics, medical comorbidity, 30-day morbidity/mortality, and outcome at 1 year. Methods: One hundred twenty-one patients not eligible for tube or bifurcated endografts were entered into the aorto-uni-iliac trial (A-I). These were compared with 153 patients in a tube (T) groups, 268 patients in a bifurcated endograft (BI) group, and 111 patients in an open control (C) group. All data were audited and independently analyzed for presentation to the Food and Drug Administration. Results: Group demographics were similar with the following exceptions. Aneurysm diameter was significantly less in the T group (51.2 mm) but similar for the A-I (57 mm), BI (54.6 mm), and C (55.6 mm) groups (P
