Simultaneous manifestation of an aortocaval and aortoduodenal fistula.

An unusual case of traumatic aortocaval and aortoduodenal fistula is presented in which the two conditions occurred simultaneously. A 19-year-old man was admitted with acute upper gastrointestinal bleeding and a pulsatile abdominal mass. An aortography revelead an aortocaval fistula and at the operation an aortocaval and aortoduodenal fistula was found. An aortocaval fistula can be discovered when a patient presents with an abdominal bruit or cardiomegaly with or without heart failure. The diagnosis of an aortoenteric fistula is difficult because of the subtleties in manifestation. The presence of an abdominal pulsatile mass and acute gastrointestinal bleeding should indicate that an aortoenteric fistula is possible.
