A report is presented on two helically reinforced polytetrafluoroethylene vascular prostheses in the femoro-popliteal (below-knee) position which thrombosed in the early postoperative period. Lateral angiography in the 45, 90 and 120 degree position of the knee joint showed short (2 mm) mild stenosis like kinking in case 1. At reoperation in case 2 the prosthesis was kinked in the longitudinal axis. Femoro-popliteal allografts across the knee joint should accomplish the following demands: 1. no kinking on postoperative lateral angiography with the knee joint bent and 2. intact prosthesis at reoperation.
本文报告了两例位于股腘（膝下）部位的螺旋增强聚四氟乙烯血管假体在术后早期发生血栓形成的病例。病例1中，膝关节处于45度、90度和120度位置时的侧位血管造影显示有短（2毫米）的轻度狭窄，类似扭结。病例2再次手术时，假体在纵轴上发生扭结。跨越膝关节的股腘同种异体移植物应满足以下要求：1. 膝关节弯曲时术后侧位血管造影无扭结；2. 再次手术时假体完整。
