Key Points

To compare the early and midterm surgical outcomes of endovascular aneurysm repair versus conventional open repair for elective abdominal aortic aneurysms.
Comparative study evaluating 131 elective abdominal aortic aneurysm operations conducted between January 1999 and March 2004.
Patients underwent either endovascular aneurysm repair with custom-made straight or tapered stent grafts (n=24) or open surgical repair (n=107).
Endovascular repair significantly reduced operative duration (131 ± 53 min vs 250 ± 76 min, p<0.01) and blood transfusion volume (0 ml vs 238 ± 345 ml, p<0.01) compared with open repair.
Cumulative survival did not differ significantly between endovascular and open repair at 1 year (88.0 ± 6.5% vs 99.0 ± 0.9%), 2 years (88.0 ± 6.5% vs 94.1 ± 2.6%), or 3 years (80.6 ± 9.2% vs 87.7 ± 3.9%).
Endovascular repair had significantly lower freedom from surgery-related complications at 1, 2, and 3 years (81.3%, 61.4%, and 47.8%) versus open repair (no midterm complications), requiring four late conversions, one rupture, and one aortoenteric fistula.

Implication

Comparative study reveals higher midterm complication rates following endovascular repair in abdominal aortic aneurysm, highlighting concerns regarding long-term device durability.
