Systolic ankle blood pressure was measured with the limb extended and then acutely flexed in four study groups. These included 11 normal individuals, 11 patients with below-knee autologous saphenous vein bypass grafts, 11 patients with polytetrafluoroethylene (PTFE) prosthetic below-knee bypass grafts, and 11 patients with femoropopliteal arterial occclusion who had not undergone bypass grafting. This study shows that normal limbs, limbs with saphenous vein bypass grafts, arteriosclerotic limbs, and those with PTFE bypass grafts all tolerate acute knee flexion without significant decrease in distal blood pressure.
在四个研究组中，分别在肢体伸展和急性屈曲状态下测量收缩期踝部血压。这四个研究组包括11名正常个体、11名下肢自体隐静脉搭桥移植患者、11名下肢聚四氟乙烯（PTFE）人工血管搭桥移植患者以及11名未接受搭桥移植的股腘动脉闭塞患者。本研究表明，正常肢体、隐静脉搭桥移植肢体、动脉硬化肢体以及PTFE搭桥移植肢体均能耐受急性膝关节屈曲，而远端血压无显著下降。
