The substitute "valve" operation, using Technique II with a Silastic (polymeric silicone) tendon designed to produce a valve-like mechanism in the popliteal vein, was performed upon 162 lower limbs (145 patients) which had deep venous insufficiency. Results achieved by this procedure were assessed clinically by Doppler ultrasound and venous pressure measurements, and partially by phlebography. Clinical improvement in 154 of 162 limbs was associated with a reduction of ambulatory venous pressure, prolongation of refilling time, interruption of popliteal reflux by Doppler, and phlebographic evidence of a functioning substitute "valve" postoperatively.
对162条下肢（145例患者）进行了替代“瓣膜”手术，采用技术II并使用硅橡胶（聚硅氧烷）腱，旨在在腘静脉中产生瓣膜样机制，这些患者患有下肢深静脉功能不全。通过多普勒超声和静脉压力测量对该手术的结果进行临床评估，并部分通过静脉造影进行评估。162条肢体中的154条临床症状改善，表现为动态静脉压降低、再充盈时间延长、多普勒显示腘静脉反流中断，以及静脉造影显示术后替代“瓣膜”功能良好。
