Stent Grafting for a Saccular Aneurysm of Cryopreserved Homograft after Implantation for Infectious Abdominal Aortic Aneurysm.

Abstract

An 82-year-old man underwent surgical repair of an infectious abdominal aortic aneurysm using a cryopreserved homograft. Twelve years later, a pseudoaneurysm at the right iliac anastomosis was treated with a stent-graft limb. Sixteen years after the initial surgery, a saccular aneurysm developed in the mid-portion of the homograft without signs of infection. Endovascular aortic repair using an AFX2 stent graft (Endologix, Irvine, CA, USA) was performed to cover the entire graft. Postoperative CT showed no endoleaks or aneurysm enlargement. Although homografts are considered infection-resistant, late degenerative complications may occur, requiring lifelong follow-up.
