超声评估下肢浅静脉手术后深静脉瓣膜功能变化

目的 应用超声评估下肢浅静脉手术改善深静脉瓣膜功能的程度及其影响因素.方法 60例住院治疗的下肢原发性深静脉瓣膜功能不全的患者(70条患肢),术前经彩色多普勒超声检查深静脉血流动力学指标,术后6个月对患者进行超声随访,比较手术前后深静脉瓣膜功能的改善程度.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%,股浅静脉和腘静脉的瓣膜功能亦均得到了改善,且二者在改善程度上没有差异.激光腔内闭合术与大隐静脉高位结扎剥脱术对深静脉反流的改善程度无差异.结论 超声检查可用于下肢浅静脉手术改善深静脉瓣膜功能的评估.

Clinic significance of ultrasound in diagnosing change of deep venous valve function after superficial operation of lower extremity

Objective To observe the function improvement of deep venous valve after superficial vein surgery of lower extremity by ultrasound.Methods Sixty patients(70 lower limbs)with primary deep venous insufficiency were enrolled tO accept surgical management of vein systems.All Datients were detected with color Doppler ultrasonography,their deep venous hemodynamics indices were measured and recorded before operation and 6 months after operation. Results The total improvement rate of the deep venous hemodynamics after superficial vein surgery was 65.7%.The valve function of suPerficial femoral vein and popliteal vein were improved after operation,and there was no significant difference between the two veins in effectiveness.The improvement for deep venous reflux had no significant difference between two surgical methods. Conclusions The superficial vein surgery of lower extremity can improve deep vein valve function in some extent.
