目的分析下肢深静脉瓣膜修复成形术治疗下肢深静脉瓣膜功能不全的临床疗效。方法对下肢原发性深静脉瓣膜功能不全的101例116条肢体实施股静脉瓣膜外修复成形术，并利用静脉功能不全评分、双向彩超、流速剖面图彩超技术和空气体积描记仪(APG)等方法对其疗效进行分析。结果随访率87.9%，随访病例症状消失，96.1%的肢体浅静脉曲张消失无复发。13例溃疡肢体中有11条在术后3～6个月溃疡消失，2条明显缩小。术前Ⅲ度返流肢体术后90%以上静脉瓣膜功能达Ⅱ度以下，67.6%的瓣膜功能恢复正常或接近正常；静脉功能不全评分从术前15.33±1.83改善到术后5.07±0.60(P<0.01)；术前Ⅳ度返流肢体术后80%以上静脉瓣膜功能达Ⅱ度以下，40.5%的瓣膜功能恢复正常或接近正常，静脉功能不全评分从术前17.38±2.67改善到术后7.25±1.12(P<0.01)。51例58条肢体经流速剖面图彩超检查示，术后静脉返流量均值比术前明显减少(P<0.01)；经APG检测术后VFI均值比术前明显减少(P<0.01)。结论下肢深静脉瓣膜外修复成形术能有效地治疗深静脉瓣膜功能不全，并可大大改善血流动力学指标，对静脉性溃疡也有一定的疗效。

Analysis of curative effect of reconstruction of venous valve of lower limbs.

Objective　To analyze the clinical effect of external valvuloplasty of femoral vein for deep vein valve insufficiency in the lower limbs.Methods　External valvuloplasty of deep vein was performed on 101 patients(116 limbs) with primary deep vein valve insufficiency and the therapeutic effects were analysed by scoring of venous dysfunction,color duplex,color doppler velocity profile technology and APG.Results　Follow-up rate was 87.9%.Symptoms of all follow-uped limbs released and varicose veins were gone in the limbs of 96.1%.Of 13 limbs with ulcers,11 limbs presented ulcer healing in 3 to 6 months after operation and 2 limbs presented ulcer decreasing.The valve imcompetence was improved Ⅱ° or below in the limbs of above 90% with Ⅲ° reflux and above 80% with Ⅳ°reflux,while valve competence was found in the limbs of 67.6% with Ⅲ° reflux and 40.5% with Ⅳ° reflux.The scoring venous dysfunction was improved from preoperative 15.33±11.83 to 5.07±0.60(P<0.01) in the limbs with Ⅲ° reflux and from 17.38±2.67 to 7.25±1.12(P<0.01) in the limbs with Ⅳ° reflux.The venous reflux volume was obviously decreased in 51 cases(58 limbs) after operation by color doppler velocity profile technology(P<0.01) and VFI was also greatly decreased postoperatively in these cases by APG(P<0.01).Conclusion　External valvuloplasty of deep vein valve was effective to treat deep vein valve insufficiency in the lower limbs.It might greatly improve hemodynamic index and had certain effect in the therapy of venous ulcers.
