Complicated Fenestrated Endovascular Repair of a Pararenal Aortic Aneurysm.

We report the case of a 77-year-old man treated with a custom-made fenestrated endograft for pararenal aortic aneurysm repair. Fenestrations for the superior mesenteric and both the renal arteries and augmented anterior valley and/or scallop for the celiac trunk were performed. The procedure was complicated by the superior mesenteric artery stent-graft entrapment from the endograft delivery system release wires and total dislodgement into the endograft main body. Superior mesenteric artery restenting and displaced stent-graft removal completed the intervention. Fenestrated-endograft deployment should be performed by a team familiar with the device, deployment system, and bail out solutions.
