This report is concerned with an analysis of 16 anastomotic aneurysms which developed in 12 patients after arterial surgery in which dacron sutures were used for all graft anastomoses. Knitted dacron grafts had been used in all but two of the original surgical procedures; a woven dacron graft had been used in one procedure and a saphenous vein graft in the other. The majority of anastomotic aneurysms occurred in the femoral triangle at the site of an end-to-side anastomosis. Five anastomotic aneurysms were caused by infection, and a variety of etiologic factors were responsible for the 11 non-infected aneurysms. Fourteen anastomotic aneurysms in 10 patients were treated surgically. A good result had been obtained in six patients; one patient required amputation of an extremity and three patients died postoperatively as a result of cardiac disease or pulmonary embolization. This report also contains a discussion of the factors affecting the occurrence of anastomotic aneurysms and a description of specific operative measures designed to decrease the incidence of these aneurysms.
本报告涉及对16例吻合口动脉瘤的分析，这些动脉瘤发生在12例接受动脉手术的患者身上，所有移植血管吻合均使用了涤纶缝线。除2例原始手术外，其余均使用针织涤纶移植物；1例手术使用了编织涤纶移植物，另1例使用了大隐静脉移植物。大多数吻合口动脉瘤发生在股三角区的端侧吻合部位。5例吻合口动脉瘤由感染引起，11例非感染性动脉瘤由多种病因所致。10例患者的14个吻合口动脉瘤接受了手术治疗。6例患者取得了良好效果；1例患者需要截肢，3例患者术后因心脏病或肺栓塞死亡。本报告还讨论了影响吻合口动脉瘤发生的因素，并描述了旨在降低这些动脉瘤发生率的具体手术措施。
