Abstract
We encountered an aortovenous fistula which caused vomiting, diarrhea and lower limb pain. A 78-year-old man complained of nausea, diarrhea and left lower limb pain. A blood test revealed acute renal failure, hepatic insufficiency and increased creatine kinase. An abdominal aortic aneurysm was found on plain computed tomography, however there was no evidence of rupture. Enhanced CT showed an aortovenous fistula, and emergency surgery was performed. The postoperative course was satisfactory. Aortovenous fistula is rare, but it can cause various types of symptoms and dysfunction in multiple organs. Therefore, it is important to consider the possibility of fistula.
