[Aneurysmal Degeneration of a Bioprosthesis].

We present a clinical case of successful correction of aneurismatic dilatation of the anastomosis zone after allotransplant implantation. In 2004 this patient underwent implantation of an arterial allotransplant of "complex architectonics" because of trauma of the iliofemoral arterial segment. After 12 years he reported appearance of discomfort in the left side of the abdomen. Duplex ultrasound scanning revealed aneurism at the site of anastomosis of the prosthesis with internal iliac artery. Therefore, we performed endovascular isolation of the aneurism with the use of a stent-graft and restoration of blood flow down to the extremity periphery has been performed.
