腔内射频闭合治疗下肢静脉曲张的应用

目的探讨静脉腔内射频闭合治疗下肢静脉曲张的疗效及应用价值。方法24例患者、30条下肢静脉曲张在DSA及超声导向下,经皮穿刺大隐静脉,通过射频导管发出热能作用于静脉壁,行大隐静脉闭合治疗。结果24例患者、30条下肢大隐静脉射频闭合治疗均获成功,未发生下肢深静脉血栓形成、皮肤烧伤及肺栓塞等严重并发症。平均每条肢体血管闭合时间17.8min,平均住院时间4.9天。术后随访1周～9个月,46.7%（14/30）下肢曲张静脉消失,53.3%（16/30）下肢曲张静脉明显减少。术后血管超声或血管造影复查,83.3%（25/30）大隐静脉主干闭塞,16.7%（5/30）大隐静脉管腔变窄,血流缓慢。未见复发,疗效满意。结论静脉腔内射频闭合术治疗下肢静脉曲张具有操作简单安全,手术时间短,创伤小,恢复快,疗效确切等优点,具有较高的临床应用价值。

Endovenous radiofrequency ablation of varicose veins

Objective To evaluate minimal jnvasive treatment for varicose vein by endoveous radiofrequency obliteration. Methods Twenty-four cases with 30 limbs were undertaken percutaneous puncture of great saphenous vein, treated with radiofrequency heat of the vein wall through an endoluminal catheter under Duplex ultrasound and DSA. Results Endovenous radiofrequency ablation was successful in all 30 cases. No deep venous thrombosis formation skin bruise and pulmonary arterial embolism were found. Complete treatment took an average of 17.8 minutes. The average hospital stay was 4.9 days. Follow-up of 1 week to 9 months, varicose veins were alleviated in 16 limbs and disappearded in 14 limbs. Duplex ultrasound or angiography confirmed 25 treated great saphenous vein have no the venous blood. The caliber of 5 treated great saphenous vein was more narrow than before. No reoccurrence with satisfied result. Conclusion Endovenous radiofrequency obliteration is a minimal invasive treatment for varicose vein with simple and safe manipulation, faster recovery, effective results.
