摘要
作者用光电容积描记（ＰＰＧ）方法测定原发性深静脉瓣膜功能不全和单纯性大隐静脉曲张共６４例９２条病肢的静脉再充盈时间（ＶＲＴ）。通过９２条病肢深静脉造影和２２条病肢静脉压测定对照分析，提示ＰＰＧ测定能作为下肢静脉瓣膜功能不全的诊断指标，应用膝上水平气压止血带的ＶＲＴ测定，可以将中、重度原发性深静脉瓣膜功能不全与单纯性大隐静脉曲张、轻度原发性深静脉瓣膜功能不全加以区别，有助于手术方式的选择，是一种有价值的、无创伤性的、反映血液动力学的功能性诊断方法。
Abstract Ninety-two lower limbs in 64 patients including primary deep venous in competence (PDVI) and simple varicose veins (SVV) were examined by photoplethysmography (PPG) in the assessment of venous refill time (VRT). All limbs underwent deep vein venography and 22 out of the 92 were raken for ambulatory venous pressure (AVP) measurment. Our results suggested that PPG evaluation could be taken as clinical diagnostic marker of venous valvular incompetence of the lower extremity.
