A Case of Aortocaval Fistula Succeeded by Surgery for Extensive Renal Failure

Abstract

A 75-year-old man consulted our hospital because of anorexia. Liver and renal dysfunctions were found in a laboratory examination and plain CT revealed Abdominal Aortic Aneurysm. Although hemodialysis was done after admission, the improvement of renal function was poor. Because enhanced CT revealed aortocaval fistula, we were consulted for purpose of surgery immediately. We performed fistula closure and Y-graft replacement of the abdominal aorta. After the operation, the renal dysfunction was immediately improved. Aortocaval fistula is rare but should be considered if patients have symptoms of right heart failure or liver and renal dysfunctions complicated with Abdominal Aortic Aneurysm.
