The incidence of early failure in 115 vein femoropopliteal grafts has been analyzed for the presence of reliable prognostic indicators of such failures. One hundred twelve patients had preoperative Doppler ultrasound assessment; 98 had intraoperative graft flow measured. Early graft failure was more prevalent in patients with rest pain and gangrene and in patients with poor runoff. Neither of these two findings had predictive value. Ninety-one percent of patients with a pressure index (ankle systolic pressure/brachial systolic pressure) less than 0.20 had early graft thrombosis. This suggests that arterial reconstruction is futile in this group. Measurement of vein graft flows intraoperatively was of value. Grafts with basal flows less than 70 ml/min uniformly thrombosed. There was significant correlation between ankle pressure index and intraoperative vein graft flow (r=.52). Both ankle pressure index and intraoperative vein graft flow provide prognostic indications of graft failure and should be of value in selecting patients for femoropopliteal reconstructions.
对115例股腘静脉移植血管早期失败的发生率进行了分析，以寻找此类失败的可靠预后指标。112例患者术前行多普勒超声评估；98例患者术中测量了移植血管血流量。移植血管早期失败在静息痛和坏疽患者以及流出道不佳的患者中更为普遍。这两个发现均无预测价值。压力指数（踝部收缩压/肱部收缩压）小于0.20的患者中有91%发生了移植血管早期血栓形成。这表明在该组患者中行动脉重建是徒劳的。术中测量移植静脉血流量具有重要意义。基础血流量小于70 ml/min的移植血管均发生了血栓形成。踝部压力指数与术中移植静脉血流量之间存在显著相关性（r = 0.52）。踝部压力指数和术中移植静脉血流量均能提供移植血管失败的预后指标，在选择股腘动脉重建患者时应具有重要价值。
