Long-tern follow-up of patients having abdominal aneurysmectomy and graft replacement will show that a considerable number develop false aneurysms at the anastomotic sites. This is the particularly true in situations in which silk suture was used for the vascular anastomoses. Successful management of this problem necessitates an awareness that unsuspected, asymptomatic ureteral obstruction can be a complicating factor. Preoperative work-up of all abdominal aortic problems should include an intravenous pyelogram. When evidence of ureteral obstruction is encountered, retrograde ureteral catheterization is important to precisely identify the point of obstruction and to aid in the ureterolysis at the time of operation. Inadvertent injury and contamination from an obstructed ureter is a situation which must be avoided when prosthetic grafting is anticipated.
对接受腹主动脉瘤切除术和移植物置换术的患者进行长期随访会发现，相当一部分患者在吻合部位出现假性动脉瘤。在血管吻合使用丝线缝合的情况下尤其如此。成功处理这一问题需要认识到，未被怀疑的无症状输尿管梗阻可能是一个复杂因素。所有腹主动脉问题的术前检查都应包括静脉肾盂造影。当发现输尿管梗阻的证据时，逆行输尿管插管对于精确确定梗阻点并在手术时协助进行输尿管松解很重要。在预期进行人工血管移植时，必须避免输尿管梗阻导致的意外损伤和污染。
