Intravenous rupture of abdominal aortic aneurysms occurs infrequently but should be considered with the coexistence of severe congestive failure, anasarca, and abdominal bruits. Six patients are presented with four survivors. In only two patients was the diagnosis considered preoperatively without angiography. Two were variants in that thrombus occluded the fistula, thereby negating findings usually manifested clinically. Diagnosis of this type can be made only during operation when copious venous bleeding ensues with evacuation of the aortic thrombus. Careful fluid management and prompt surgery are prerequisites to obtaining a successful outcome. Repair is accomplished easily by suturing the fistula from the aortic aspect, but care is required to avoid dislodgement of thrombus and atherosclerotic debris resulting in pulmonary embolism.
