: Fenestrated endovascular aortic repair of aneurysms with challenging necks has advanced significantly over the last three decades. In cases with extremely hostile proximal necks, such as the one described here (a common trunk between the superior mesenteric artery and the celiac artery), it may be necessary to cover the celiac trunk to ensure better graft attachment and avoid endoleaks. However, unexpected events can still occur, even with collateral circulation present. To our knowledge, this is the second reported case of gallbladder necrosis following fenestrated endovascular aortic repair.
