From October 1978 to June 1983, 64 sequential bypass grafts were performed in 59 patients with limb-threatening ischemia. These patients were classified into three study groups as follows: reversed saphenous vein graft alone (12), composite sequential (proximal polytetrafluoroethylene [PTFE] and distal vein) graft (30), and PTFE graft in entirety (22). Graft patency was confirmed in all cases by serial Doppler ankle pressure measurements or by angiography. Cumulative life-table patency rates were then compared over a period of 27 months. The patency rates for composite sequential grafts using a distal short segment of vein were statistically indistinguishable from those for bypasses performed entirely with saphenous vein. These yielded a patency rate of 80% at 1 and 2 years. In contrast, the 1- and 2-year patency rates of the PTFE sequential grafts were 52% and 47%, respectively (p less than 0.05). Composite sequential bypasses using an otherwise inadequate segment of saphenous vein are a sound alternative revascularization procedure, with a patency rate comparable to that of reversed saphenous vein bypasses.
1978年10月至1983年6月，对59例患有肢体威胁性缺血的患者进行了64例序贯旁路移植术。这些患者被分为以下三个研究组：单纯大隐静脉倒置移植组（12例）、复合序贯移植组（近端聚四氟乙烯[PTFE]和远端静脉）（30例）以及全PTFE移植组（22例）。所有病例均通过连续多普勒踝压测量或血管造影术确认移植血管通畅。然后在27个月的时间内比较累积寿命表通畅率。使用远端短段静脉的复合序贯移植的通畅率与完全使用大隐静脉进行的旁路移植的通畅率在统计学上无显著差异。这些移植血管在1年和2年时的通畅率为80%。相比之下，PTFE序贯移植在1年和2年时的通畅率分别为52%和47%（p<0.05）。使用原本不充足的大隐静脉段进行复合序贯旁路移植是一种合理的替代血管重建手术，其通畅率与大隐静脉倒置旁路移植相当。
