Infected iliac artery aneurysm with aortocaval fistula.

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.
