Sixty-five patients treated by femoropopliteal bypass in 1974 were surveyed; the mean follow-up time was 10.4 months. The one year cumulative patency rate for velour Dacron was 50 percent; this was less successful than were the results from a comparable group in which vein grafts were used (79 percent). These poor results were due principally to the high failure rate of velour Dacron in patients suffering from clinically severe ischemia. In these only one in four grafts remained patent. If a less than perfect arteriographic runoff was obtained, only one in three still functioned. These results occurred despite high intraoperative graft flows. It appears that velour Dacron may be acceptable in patients treated for claudication if no adequate vein is available. This prosthesis gives an unacceptably high failure rate in patients with severe ischemia.
对1974年接受股腘动脉搭桥术治疗的65例患者进行了调查；平均随访时间为10.4个月。涤纶绒血管的一年累积通畅率为50%；这一结果不如使用静脉移植物的可比组（79%）成功。这些不良结果主要是由于涤纶绒血管在临床上严重缺血的患者中失败率高。在这些患者中，只有四分之一的移植物保持通畅。如果动脉造影显示的血流情况不太理想，仍能正常发挥功能的移植物只有三分之一。尽管术中移植物血流量很高，但仍出现了这些结果。如果没有合适的静脉可用，对于因间歇性跛行接受治疗的患者，涤纶绒血管似乎是可以接受的。在严重缺血的患者中，这种假体的失败率高得令人无法接受。
