Hybrid Treatment of Coexisting Renal Artery Aneurysm and Abdominal Aortic Aneurysm in a Gallbladder Cancer Patient.

Renal artery aneurysm (RAA) is uncommon, and the coexistence of an abdominal aortic aneurysm (AAA) is an extremely rare condition with potentially high life-threatening mortality in case of rupture. Aneurysms can be treated by endovascular intervention or open surgery. Although most of aneurysms are treated by endovascular intervention, open surgery is often necessary for RAAs associated with the proximal renal bifurcation or the branches in the distal renal arteries. We report a rare case of coexisting RAA with AAA treated by hybrid method, consisting of endovascular aneurysm repair for AAA and open surgery for RAA located adjacent to the distal branches of the renal artery.
