Reporting mid- and long-term results of endovascular grafting for abdominal aortic aneurysms using the aortomonoiliac configuration

Purpose

This study evaluated the feasibility, efficacy, and durability of a specific aortomonoiliac endograft for the treatment of abdominal aortic aneurysm (AAA) during a midterm follow-up.

Methods

From January 2002 until November 2008, 106 patients (6 women; mean age, 73.37 ± 7.39 years) were treated for an AAA using an EndoFit aortomonoiliac graft (LeMaitre Vascular, Burlington, Mass). All procedures were elective.

Results

Mean follow-up was 34.9 months (SD, 20.08; range, 2-81 months). Long-term data (follow-up >60 months) were available for nine patients, none of which reported any vascular or procedure related complications. Three of the 106 patients (2.83%) died during early follow-up (<30 days); eight died during late follow-up (7.54%). Endograft infection developed in two patients (1.88%), and an aortoduodenal fistula developed in two (1.88%). Also observed were 15 type II (14.15%) and three type I (2.83%) endoleaks. Femorofemoral bypass thrombosis was detected in two patients (1.88%).

Conclusion

In this retrospective analysis, the aortomonoiliac configuration for elective AAA repair was proven to be safe and efficacious. Midterm and long-term follow-up results in this series compare well with previously reported results for AAA endografting using both bifurcated and aortomonoiliac endoprostheses.
