Abstract

Objective. To evaluate the effectiveness of surgery in treating primary varicose veins in the lower limbs by photoplethysmography (PPG) and duplex mapping (DM). Method. Forty-eight lower limbs were clinically evaluated according to the CEAP classification system and subjected to PPG and DM exams. Each limb had a venous refill time (VRT) of <20 seconds and a normal deep vein system (DVS) by DM. Results. The mean pre- and postoperative VRTs were 13.79 and 26.43 seconds, respectively (P < 0.0001). After surgery, 42 limbs (87.50%) had normal results by PPG (VRT > 20 seconds). Four limbs (8.33%) showed improved VRTs, but the VRTs did not reach 20 seconds. In the 2 limbs (4.17%) that maintained their original VRTs, the DM exams showed the presence of insufficient perforating veins. Conclusion. In most cases, PPG allows for a satisfactory evaluation of the outcome of varicose vein surgery.

摘要

目的。通过光电容积脉搏波描记法（PPG）和双功超声造影（DM）评估手术治疗下肢原发性静脉曲张的有效性。方法。根据CEAP分类系统对48条下肢进行临床评估，并进行PPG和DM检查。每条下肢的静脉充盈时间（VRT）<20秒，且DM显示深静脉系统（DVS）正常。结果。术前和术后VRT的平均值分别为13.79秒和26.43秒（P<0.0001）。术后，42条下肢（87.50%）PPG检查结果正常（VRT>20秒）。4条下肢（8.33%）的VRT有所改善，但未达到20秒。在2条维持原VRT的下肢（4.17%）中，DM检查显示存在交通静脉功能不全。结论。在大多数情况下，PPG能够对静脉曲张手术的结果进行满意的评估。
