One of the most important prerequisites prior to femorocrural bypass is the identification of a patent calf vessel. To determine the ability of three preoperative investigations to demonstrate patent distal vessels we compared preoperative conventional arteriography, Doppler ultrasound measurement of ankle systolic pressure (ASP) and pulse generated run-off (PGR). PGR and ASP both identified significantly more calf vessels than did preoperative conventional arteriography. However, only PGR had the ability to distinguish those vessels suitable for bypass grafting from those unsuitable for grafting. These results demonstrate that PGR is the investigation of choice prior to femorocrural bypass.
股腘动脉搭桥术前最重要的前提条件之一是确定小腿血管通畅。为了评估三种术前检查显示远端血管通畅的能力，我们比较了术前传统动脉造影、多普勒超声测量踝部收缩压（ASP）和脉冲激发血流（PGR）。PGR和ASP识别出的小腿血管均明显多于术前传统动脉造影。然而，只有PGR能够区分适合搭桥移植的血管和不适合移植的血管。这些结果表明，PGR是股腘动脉搭桥术前的首选检查方法。
