    Abstract:
    INTRODUCTION: Abdominal aortic aneurysms can be complicated by some conditions and aortocaval fistula is one of them. Aortocaval fistula is an unusual entity. CASE REPORT: A male patient was admitted to the hospital for abdominal pain and leg oedema of three days duration. In addition, severe anuria was also noted. We determined a fistula from the right lateral wall of aneurysm to the distal of vena cava inferior. The aortocaval fistula was closed with pledged-reinforced 4/0 polypropylene suture in the aneurysmal wall. At the postoperative 10th day, he was discharged with normal renal function. DISCUSSION: After a long-term untreated fistula, right-sided heart failure, acute renal and hepatic insufficiency, deep vein thrombosis and pulmonary thrombo-embolism can be seen in these patients. Increased venous pressure should be the reason for decreased arterial flow results in renal insufficiency. Emergency intervention in these patients saves the patient's life as well as prevents irreversible organ failure.
