Abstract: Anatomical variations of the renal arteries may complicate endovascular repair of infrarenal abdominal aortic aneurysms (AAA). Occlusion of renal branches may be necessary to seal the aneurysm sac efficiently. Depending on the size of the affected renal arteries and the supplied parenchyma, this can lead to loss of renal function. Iliac branch devices (IBDs) have been created in order to preserve the internal iliac artery in aortoiliac or isolated iliac aneurysms; however, IBDs have the potential to maintain patency of other arteries as well. This case report describes the off-label use of an IBD inside the main body of a bifurcated endoprosthesis in a patient with an AAA and multiple renal arteries in order to preserve the main renal artery that emerges directly out of the aneurysm sac. Special considerations such as limited craniocaudal dimensions for endoprosthesis placement and the reduced vascular space are discussed.
