Technological advances in artificial blood vessels used in arterial reconstructive surgery have contributed significantly to the development of this field. The 5-year cumulative patency rate of femoropopliteal bypass using knitted Dacron grafts at Keio University Hospital is over 80% (1). This rate is comparable with the results of femoropopliteal bypass surgery using autovein grafts (2, 3, 4). Therefore, we usually perform femoropopliteal bypass using a knitted Dacron graft. However, pseudoaneurysm formation remains one of the major complications of arterial reconstructive surgery. In most cases, a pseudoaneurysm is caused by infection or external injury, and is detected at the anastomotic site. This paper deals with an extremely rare, non-anastomotic aneurysm caused by total disruption in the middle of an externally supported knitted Dacron graft used for femoropopliteal bypass.
用于动脉重建手术的人造血管技术进步对该领域的发展做出了重大贡献。庆应义塾大学医院使用针织涤纶移植物进行股腘动脉搭桥术的5年累积通畅率超过80%（1）。该比率与使用自体静脉移植物进行股腘动脉搭桥手术的结果相当（2、3、4）。因此，我们通常使用针织涤纶移植物进行股腘动脉搭桥术。然而，假性动脉瘤形成仍然是动脉重建手术的主要并发症之一。在大多数情况下，假性动脉瘤是由感染或外部损伤引起的，并且在吻合部位被检测到。本文讨论了一种极其罕见的非吻合口动脉瘤，它是由用于股腘动脉搭桥的外部支撑针织涤纶移植物中部完全断裂引起的。
