Seven-Year Approach Evolution of the Aortoiliac Occlusive Disease Endovascular Treatment

Abstract

Background: Endovascular treatment is now considered the first-line therapy for the aortoiliac occlusive disease (AIOD). We report our experience with the total endovascular treatment of infrarenal and pararenal aortoiliac occlusions and the 7-year approach evolution.

Methods: A total of 22 patients underwent total endovascular treatment of AIOD from January 2008 to September 2014. Bare metal stents in kissing configuration were deployed in 9 cases, covered stents in kissing configuration in 9 patients and the aortic bifurcation reconstruction with the Y-guidewire configuration technique was performed in the last 4 patients.

Results: Technical success was 100%. Perioperative mortality rate was 4.5%. ankle-brachial index improved from 0.49 ± 0.19 to 0.96 ± 0.05 at the right side and from 0.53 ± 0.17 0.98 ± 0.04 at the left side (P < 0.01). Mean follow-up was 39.5 months (range, 5-80 months). The primary patency rate was 95.2% at 1 year and 90.5% at 3 years, and the secondary patency rate was 95.2% at 1 year and 100% at 3 years.

Conclusions: Different stent types and configurations used for the aortoiliac endovascular treatment offer all the benefits of these materials for treatment on a case-by-case basis. The Y-guidewire configuration technique for the aortic bifurcation reconstruction may render the procedure more feasible. More cases and longer follow-up are necessary before the widespread use of this technique.
