• From April 1975 to September 1980, 16 symptomatic bovine graft aneurysms were identified in 200 grafts used for long-term hemodialysis. Aneurysms occurred in five (3.6%) straight forearm grafts, two (33%) reversed forearm grafts, two (33%) straight thigh grafts, and seven (18.9%) upper arm grafts. Mean blood pressures were similar in the aneurysm and nonaneurysm groups (142/81 vs 153/83 mm Hg). At operation, the aneurysms were determined to be true in three patients and false in 13. Five patients were treated by graft ligation and aneurysm excision and 11 by aneurysm excision and graft revision, with additional graft survivals of one to 25 months. In conclusion, bovine graft aneurysms are usually false and are more frequent in proximal grafts. In the absence of infection, resection is indicated and will result in considerable prolongation of graft survival.
