Endovascular Treatment of a Late False Aneurysm Complicating Open Suprarenal Mycotic Aneurysm Repair with a Cryopreserved Aortic Homograft

We report a patient who was initially treated for a suprarenal mycotic aortic aneurysm. The aneurysm repair was performed using a cryopreserved arterial homograft and debranching of visceral arteries. Five years later, the patient was referred due to a large symptomatic false aneurysm at the distal homograft anastomosis. Endovascular repair was indicated and performed using a bifurcated Medtronic composite stent graft. The procedure was uneventful, while control angiography showed complete exclusion of the false aneurysm. Within 6 months of follow-up, the endograft showed favorable position and maintained patency with no signs of endoleaks. We discuss the role of the cryopreserved homografts for in situ repair of mycotic aortic aneurysms and comment on possible late complications after placing those grafts.
