下肢静脉曲张行浅静脉手术对深静脉瓣膜功能影响的研究

目的：探讨下肢浅静脉手术改善深静脉瓣膜功能的程度及影响效果的因素。方法：收集住院行浅静脉手术治疗的下肢原发性深静脉瓣膜功能不全的患者60例（70条肢体）, 术前经双功能彩色多普勒超声检查记录深静脉血流动力学指标。浅静脉手术后6个月进行随访, 行超声复查, 比较手术前后深静脉瓣膜功能。 结果：下肢浅静脉手术后深静脉瓣膜功能的总体改善率为65.7%；病程超过20年较之病程小于或等于20年的患者改善不佳的可能性高4.355倍；股浅静脉和腘静脉同时存在倒流的患者比两静脉各自单独存在倒流的患者改善不佳的可能性高4.247倍；年龄大于60岁比年龄小于或等于60岁的患者改善不佳的可能性高3.516倍；股浅静脉和腘静脉瓣膜功能改善的程度差异无显著性（P＞0.05）。 结论：下肢静脉曲张单纯行浅静脉手术可在一定程度上改善深静脉瓣膜功能, 手术近期效果好, 可有选择性地应用于某些早期深静脉瓣膜功能不全的患者。

Research on effect of lower extremity superficial varicose vein operation on deep venous valve function

Objective To discuss the efficiency and influential factors that can improve the function of deep venous valve after superficial vein surgery of lower extremity.Methods Sixty(70 limbs) patients with primary deep venous insufficiency were enrolled to accept surgical management of superficial vein systems.All patients were examined with color Doppler ultrasonography,and their deep venous hemodynamics index was measured,recorded and compared before operation and six months after operation.Results The total imp...
