Renal artery aneurysms are rare and typically found incidentally. Risk of rupture drives the incentive for repair, which can be achieved by both open and endovascular techniques. Ex vivo repair with renal auto-transplantation is recommended for complex aneurysms involving distal or multiple arteries. Here we describe a successful treatment of a renal artery aneurysm after previous endovascular treatment failure. A multi-layered stent was left misplaced inside of the aneurysm. Ex vivo repair with renal auto-transplantation allowed for complete aneurysm exclusion. With increasing use of endovascular techniques, failure of endovascular treatment might become a common indication for ex vivo repair in renal artery aneurysms.
