The Long-Term Results of Covered Endovascular Aortic Bifurcation Repair in Complex Aortoiliac Disease: A Two-Year Follow-Up.

Abstract

Background: We aimed to investigate the two-year outcomes of covered endovascular reconstruction (CERAB) of the aortic bifurcation in patients with complex aortoiliac occlusive dis ease. Methods: This study was prospectively initiated, with data retrospectively collected from 40 patients categorized as TASC II B, C, and D based on computed tomography angiography (CTA) findings. All patients underwent the CERAB procedure. We assessed the procedural outcomes, including clinical and symptomatic improvements, as well as patency rates over a two-year follow-up period. Results: A total of 40 patients (33 males and 7 females) with aorto-occlusive disease were treated using the CERAB procedure and included in this observational study. The technical success rate was 100% across all procedures. At 36 months, the overall primary patency, assisted primary patency, and secondary patency rates were 85%, 90%, and 92.5%, respectively. Conclusions: The two-year results of this study suggest that CERAB offers patency rates comparable to those reported in other studies for complex aorto-occlusive bifurcation diseases. The procedure showed favorable patency rates, particularly for more advanced TASC II B, C, and D lesions.
