The surgical approach to bleeding visceral artery aneurysms has a mortality rate of 16-50% that is dependent primarily on anatomic location and underlying cause. Nineteen patients were studied over a 10-year period who were definitively treated by embolization. There was a 79% success rate and no mortality. The cause of the aneurysms was pancreatitis in 13 patients, trauma in four patients, subacute bacterial endocarditis in one patient, and secondary to biliary tract surgery in one patient.
