The prognostic value of Doppler-derived ankle systolic pressure indices for predicting the patency of vein bypass grafts in the lower extremity was analyzed in 126 vein bypass grafts performed for limb salvage. Early or late graft failure was not found to correlate with the preoperative ankle systolic pressure index (ASPI). Intraoperative blood flow measurements did not correlate with the preoperative ASPI. An intraoperative graft flow of less than 0.7 at 24 to 48 hours, or an increase in ASPI of less than 0.4 were prognostic signs of early vein graft failure.
对126例为挽救肢体而进行的下肢静脉搭桥手术中，多普勒衍生的踝部收缩压指数预测静脉搭桥通畅情况的预后价值进行了分析。未发现早期或晚期移植失败与术前踝部收缩压指数（ASPI）相关。术中血流测量与术前ASPI无关。术后24至48小时移植血流量小于0.7，或ASPI升高小于0.4是早期静脉移植失败的预后征象。
