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 non-aneurysm 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.
1975年4月至1980年9月期间，在200例用于长期血液透析的移植物中，发现了16例有症状的牛移植血管动脉瘤。动脉瘤出现在5例（3.6%）前臂直形移植物、2例（33%）前臂翻转移植物、2例（33%）大腿直形移植物和7例（18.9%）上臂移植物中。动脉瘤组和非动脉瘤组的平均血压相似（142/81 vs 153/83 mmHg）。手术时，确定3例患者的动脉瘤为真性，13例为假性。5例患者接受了移植物结扎和动脉瘤切除治疗，11例接受了动脉瘤切除和移植物修复，移植物额外存活时间为1至25个月。总之，牛移植血管动脉瘤通常为假性，且在近端移植物中更为常见。在无感染的情况下，应进行切除，这将显著延长移植物的存活时间。
