Aortocaval fistula as a complication of leaking aortic aneurysm.

The successful management of 2 patients is reported, each involving the closure of a fistula into the inferior vena cava as a sequel to the rupture of an atherosclerotic aortic aneurysm. It is an uncommon complication which should be suspected in the presence of an aortic aneurysm with a loud machinery bruit. Associated peripheral cyanosis and venous pulsation in the accessible proximal veins of the lower extremity and priapism afford strong supporting evidence.
