股浅静脉瓣膜外修复成形术后血流动力学动态变化74例分析

目的检测股浅静脉瓣膜外修复成形术后血流动力学动态变化 ,以分析其治疗下肢深静脉瓣膜功能不全的疗效。方法回顾性分析原发性下肢深静脉瓣膜功能不全 74例 ( 96条肢体 )的资料 ,利用流速剖面图彩超和空气体积描记仪分别于术前、术后 1、3个月及 1年进行血流动力学指标检测并进行统计学分析。结果全组术后静脉返流量、灌注指数、静脉功能不全评分指标于术后 1、3个月、1年均较术前显著降低 (P <0 0 1)。而射血分数、剩余容积分数均值于术后 3个月、1年较术前明显改善 (P <0 0 1)。溃疡愈合率达 78 8% ( 2 6 /33) ,术后 93 6 %的肢体各种症状体征消失和明显缓解。结论股浅静脉瓣膜外修复成形术可显著改善血流动力学状况 ,对治疗原发性下肢深静脉瓣膜功能不全及静脉性溃疡有确切疗效

Hemodynamic changes after external valvuloplasty of the superficial femoral vein

ObjectiveTo analyze the effect of external valvuloplasty of the superficial femoral vein for primary deep venous valvular incompetence in the lower limbs (PDVI). Methods Consecutive seventy four cases(96 limbs) of PDVI were enrolled for prospective study, and color Doppler velocity profile technology and APG were performed preoperatively, the first month, the third month and the first year postoperatively. Results Postoperative venous reflux volume, VFI and score of venous dysfunction significantly decreased ( P <0 01). The EF,RVF significantly improved ( P <0 01). Ulcer healing rate was 78 8%(26/33). Symptoms and signs relieved or disappeared in 93 6% limbs. Conclusions External valvuloplasty of the superficial femoral vein greatly improves the hemodynamic status. It has definite curative effect for PDVI and venous ulcer.
