Treating iliac aneurysm using the Nellix Endovascular Sac Sealing System

Abstract

As endovascular treatment of abdominal aortic aneurysms has become established, there has been growing focus on treatment of the aneurysmal iliac artery. Isolated, large iliac aneurysms >30 mm pose a risk of rupture, but, in addition, 20% to 30% of abdominal aortic aneurysms are associated with iliac aneurysmal dilatation, which can compromise long-term outcomes. Endovascular solutions are evolving and until recently have utilized standard stent graft technology. The endovascular aortic sealing system was introduced as a new, effective method for the treatment of infrarenal aortic aneurysms. In this article, we present our recent extended use of the Nellix system, with or without a combination of adjuvant endovascular techniques, in the treatment of 84 common iliac artery aneurysms. The results support the use of endovascular aortic sealing system in endovascular therapy for aneurysmal iliac pathologies. Different endovascular sealing techniques for the treatment of common iliac artery aneurysms, re-interventions, and extended follow-up are also discussed.
