Infected iliac artery aneurysm with aortocaval fistula

Abstract

Case: We report a case of an infected iliac artery aneurysm complicated by an aortocaval fistula. Outcome: A 74-year-old-man was admitted with fever, chills, general fatigue, and appetite loss. The patient was diagnosed with an infected iliac artery aneurysm, which was controlled with antibiotics preoperatively. During hospitalization, deep vein thrombosis developed with a pulmonary embolism resulting from an aortocaval fistula. The patient was successfully operated on with in situ autologous vein graft reconstruction.Conclusion: An infected iliac artery aneurysm with aortocaval shunt has rarely been reported. We successfully treated the patient with a combination of appropriate i.v. antibiotics and surgical resection.

Phlegmasia cerulea dolens as an initial manifestation of a fistula between a ruptured iliac artery aneurysm and the iliac vein

“…We considered the possibility of infection and prepared a retroperitoneal detour; however, we did not use it, because there was no clear intraoperative sign of infection. A case of an infected CIAA with an ACF has been reported, and it was reconstructed with a reversed femoral vein graft 14 . If infection is suspected intraoperatively, a detour or an autologous graft or homograft can be considered.…”
