Endovascular iliac branch devices for iliac aneurysms

The evolution of endovascular techniques has increased the proportion of patients with abdominal aortic aneurysms suitable for treatment with endovascular aneurysm repair (EVAR). Developments in fenestrated and branched technology provide an endovascular solution to incorporate the visceral branches and iliac arteries into the repair, expanding the indications of EVAR. Iliac branch devices (IBDs) allow preservation of flow into one or both internal iliac arteries in patients with ectatic or aneurysmal iliac arteries. The technique has been performed with high technical success rates and no added morbidity and mortality as compared with standard EVAR, potentially decreasing pelvic ischemic complications associated with hypogastric exclusion. This article summarizes the state of the art on IBD design, procedure planning, implantation, and clinical results.
