Endovascular repair of a pancreatic allograft mycotic aneurysm: two-year follow-up.

Objective: To describe midterm outcome of endovascular stent-graft repair of a mycotic aneurysm associated with a peripancreatic allograft abscess after transplantation.

Methods: A 46-year-old woman underwent combined kidney and pancreas allograft transplantation under heavy immunosuppression. She developed a peripancreatic allograft abscess with associated mycotic aneurysm of the pancreatic allograft donor iliac artery 2 months after transplantation. Endovascular stent-grafts were used to exclude the aneurysm, retaining normal pancreatic allograft function over the next 2 years.

Conclusions: Allograft arterial mycotic aneurysm development after transplantation is a rare but potentially life-threatening problem. This case suggests that control of a mycotic aneurysm may be obtained with stent-grafting in the presence of active infection under intense immunosuppression, avoiding allograft pancreatectomy.
