摘　　要：本文研究彩超检查下肢静脉瓣膜功能不全的血流返流。对作股浅静脉第一对瓣膜重建术的４０例患者进行彩超检查，并与手术结果对照分析：认为静脉血流返流时间阈值０．５秒可较准确地诊断下肢静脉有无返流。静脉血流返流指数与手术探查的静脉血流返流严重程度二者具有较好的相关性（ｒ＝０．８７４７Ｐ＝０．０００），股浅静脉第一对瓣膜有轻度返流者的静脉血流返流指数为０．７４３３±０．２０９６，中度者为１．４６７８±０．４０６２，重度者为３．４１３３±０．３８５５。轻中度静脉血流返流者的静脉血流返流指数与重度静脉血流返流者的静脉血流返流指数相比具有显著性差异（Ｐ＝０．０００）。We studied the venous reflux parameters of the lower extremity vessels with color Doppler flow imaging(CDFI)for 40 patients prior valve reconstruction of superficial femoral vein.CDFI parameters of venous reflux was compared with surgical findings.High accuracy of venous reflux,defined as reverse flow greater than 0 5 second,and well correlated(r=0 8747,P=0 000)with surgical detection.Mild venous reflux index was 0 7433±0 2096,moderate venous reflux index was 1 4678±0 4062 and severe venous reflux index was 3 4133±0 3855.They were quite different.
