曲张浅静脉激光闭合术对原发性深静脉功能不全中远期血流动力学和瓣膜功能的影响

目的观察曲张浅静脉激光闭合术对下肢原发性深静脉功能不全中、远期血流动力学和瓣膜功能的影响。方法选择2010年1月-12月接受曲张浅静脉激光闭合术治疗的854例下肢原发性深静脉功能不全病例,应用彩色多普勒超声评估术前和术后1、6和12个月时,股浅静脉第一对瓣膜静脉反流指数的变化。结果 321例术前轻度瓣膜反流患者,在术后1、6和12个月时的瓣膜反流改善率分别为57.6%、72.0%和86.9%。301例中度瓣膜反流患者和232例重度瓣膜反流患者,在术后1、6和12个月时瓣膜反流改善率分别为15.0%、23.6%、26.2%和8.2%、13.4%和19.4%。轻度瓣膜反流患者术后瓣膜反流改善率与中度和重度患者相比,差异均有统计学意义（P均〈0.05）。结论曲张浅静脉激光闭合术能够有效改善股浅静脉第一对瓣膜轻度反流患者的瓣膜反流程度。

The long-term result of hemodynamics and valvular function after endovenous laser ablation of varicose veins in the primary deep venous insufficiency

Objective To observe the long-term results of hemodynamics and valvular function after endovenous laser ablation of varicose veins in the primary deep venous insufficiency.Methods Between January and December 2010,854 patients diagnosed as primary deep venous insufficiency had their varicose veins treated by endovenous laser ablation.Color doppler ultrasound was used to measure the venous reflux index of the first valve of superficial femoral vein preand post-operative,at 1,6 and 12 months after surgery.Results The correction rate of valvular reflux in mild reflux cases were 57.6%,72.0% and 86.9% respectively at 1,6 and 12 months after surgery.The results of moderate and severe reflux cases were 15.0%,23.6%,26.2% and 8.2%,13.4%,19.4% respectively.The correction rate of valvular reflux in mild reflux cases after operation was better than the moderate and severe groups(both P <0.05).Conclusion Endovenous laser ablation of varicose veins can correct the deep venous incompetence of the lower extremity in mild reflux groups.
