摘　　要：目的应用彩色多普勒超声观察下肢静脉瓣膜关闭功能不全,对静脉血流返流程度定性诊断。方法对600例经二维(2D)、血管改善技术(Cvlaify VE)、彩色多普勒(CDFI)、脉冲多普勒(PW)检查下肢静脉的超声结果回顾分析,总结超声诊断下肢静脉瓣膜关闭功能不全的指标及诊断价值。结果 600例中98例下肢静脉瓣膜关闭功能不全有108条,左下肢54例,右下肢44例;其中大隐静脉60条,股总静脉和股浅静脉20条,大隐静脉和股浅静脉20条,小腿交通静脉8条。Valsalva试验,交谈和站立结合CDFI血管腔内均出现双向血流;PW:VCT≥0.7s、Vmax>7-10cm/s定为判断静脉瓣膜关闭功能不全的阳性指标,根据VCT的大小分为Ⅰ、Ⅱ、Ⅲ、Ⅳ级。结论彩色多普勒超声可对下肢静脉瓣膜关闭功能不全的返流程度,进行快速的定性定量诊断。Objective To analyze and evaluate the application of colour Doppler imaging in diagnosing of chronic venous insufficiency and the degrees of the venous reflux.Methods 600 cases with lower extremity vessels were examined by using 2D,Clarify VE and CDFI and PW technique.And valve closure,the opening degree and the shape size were observed.Results In 600 patients,108 legs in 98 patients with chronic venous insufficiency,54 of them have this problem on left leg,while 44 on right leg;among them there were 60 cases of great saphenous vein,20 cases of common femoral vein and superficial femoral vein,20 cases of great saphenous vein and superficial femoral vein and 8 cases of perforating veins of leg.Bidirectional flow was found in Valsalva maneuver,talks with the patients and standing position.PW retrograde flow waveform could appear,flow back time≥0.7s and back-streaming speed7-10cm/s was regarded as the positive criteria for diagnosing chronic venous insufficiency.Chronic venous insufficiency was sorted into four grades according to the VCT.Conclusion The color Doppler ultrasound device could make a fast qualitative and quantitative detection on chronic venous insufficiency retrograde flow through the blood pressure test.
