EVS植入术治疗原发性下肢深静脉瓣膜功能不全

EVS implantation in the treatment of primary deep venous insufficiency

目的评估静脉瓣膜外支撑环(EVS)植入术治疗原发性下肢深静脉瓣膜功能不全的疗效和应用价值。方法将66例病人(69侧患肢)随机分为两组,A组37侧,B组32侧。A组,股浅静脉第1对瓣膜行EVS植入术;B组行股静脉壁环形缩窄术。以下肢静脉顺行造影评估疗效。结果术后造影显示A组26侧患肢股浅静脉瓣膜功能恢复;B组中6例见逆流(P<0.05)。结论EVS植入术安全可靠,操作简便,实用,易标准化,疗效满意。

Objective To evaluate therapeutic effect of external valve support(EVS) implantation in the treatment of primary deep venous insufficiency(PDVI).Methods 66 cases of deep venous insufficiency were randomly divided into Group A(37limbs) and GroupB(32limbs). The patients of Group A underwent EVS implantation at the fist valve of the superficial femoral vein,while those in Group B were treated with encircling suturing of the venous wall. Postoperative effects were evaluated by ascending venography.Results Postoperative venogrphy was performed in 26 Patients of GroupA and in 21 patients of Group B.All the valve functions of the superficial feroral vein were restored except in 2 cases of Group A and 6 cases of Group B(P<0.05).Conclusion EVS implantation is a safe,simple and reliable procedure.
