Insights and Clinical Implications from the pELVIS Registry for the Treatment of Aneurysms Involving the Iliac Bifurcation

The pErformance of iLiac branch deVIces for aneurysmS (pELVIS) Registry is the largest retrospective analysis of prospectively collected data on the use of iliac branch devices (IBD) for the treatment of iliac and aortoiliac aneurysms. It shows the feasibility of the technique with good short- and mid-term results. The most common anatomical challenge for IBD use is the presence of aneurysmal deterioration of the internal iliac arteries (IIA). Experience acquired in the registry treating concomitant aneurysmal lesions of the IIA provides significant information on the performance of IBDs for this specific clinical presentation. Treatment of isolated aneurysms in the common iliac artery without extension to the infrarenal aorta showed favourable results with lower costs, and lower use of irradiation and contrast media. Overall, the relatively low procedure-related complications and repeat interventions show broad applicability of the technique. Further analysis is required to evaluate the longstanding performance of IBD.
