Treatment of Aortoiliac Aneurysms With the Iliac Bifurcated Device for Preservation of Internal Iliac Artery Flow

Introduction: The iliac bifurcated device (IBD) is an innovative endovascular device for aortoiliac aneurysm repair. The objective of this study is to provide further evidence on the efficacy and safety of the device. Study Design: Case series study with retrospective analysis of prospectively collected nonrandomized data. Methods: Between 2007 and 2010, all consecutive IBD placements were analyzed. The main outcomes included (1) technical failure; (2) morbidity and mortality; and (3) late outcomes. Prospective follow-up was performed by interval computed tomography scanning. Results: In all, 27 consecutive patients had elective placement of 28 IBDs. Mean operating time was 251.1 65.4 minutes, mean fluoroscopy time was 63.9 +/- 27.2 minutes, and mean contrast volume used was 186.2 +/- 106.7 mL. Periprocedural type I endoleak occurred in 2 patients. No aneurysm-related adverse events were recorded. Conclusion: We demonstrate that IBDs can be used in patients with aortoiliac aneurysms and are associated with satisfactory medium-term results as expressed by high patency and low reintervention rates.
