As of the end of September 1989, 52 EXS Dacron grafts had been implanted for femoropopliteal bypass operations. The distal ends of 27 grafts were anastomosed to above-knee popliteal arteries and those of 25 grafts to below-knee popliteal arteries. The cumulative patency rate of above-knee grafts was 71.3% at 54 months, and that of below-knee grafts was 78.8% at 48 months (n.s.). Kinking and stenosis of the arteriosclerotic proximal and/or mid popliteal artery when the knee was bent were angiographically remarkable. These changes may explain why some femoropopliteal grafts occlude with time and why the late results of above-knee grafts are not much better than those of below-knee grafts.
截至1989年9月底，已植入52条EXS涤纶移植物用于股腘动脉搭桥手术。27条移植物的远端与膝上腘动脉吻合，25条移植物的远端与膝下腘动脉吻合。膝上移植物在54个月时的累积通畅率为71.3%，膝下移植物在48个月时的累积通畅率为78.8%（无显著性差异）。膝关节弯曲时，动脉硬化的腘动脉近端和/或中段出现扭结和狭窄，血管造影显示明显。这些变化可以解释为什么一些股腘动脉移植物会随着时间的推移而闭塞，以及为什么膝上移植物的远期效果并不比膝下移植物好多少。
