Radiofrequency ablation of superficial and perforator veins for venous insufficiency has emerged as a leading alternative to traditional vein stripping operations. This percutaneous technique can be performed in less than an hour using local anesthetic or sedation. The VNUS Closure catheters (VNUS Medical Technologies, San Jose, California) work by resistive heating in the vein wall that is constantly monitored through a feedback loop to the VNUS Closure generator. Side effects are less than with other endovenous ablation techniques and patients resume normal activity immediately. The new ClosureFAST catheter is an important advancement that combines the speed of endovenous laser ablation with the expected fewer side effects of radiofrequency ablation.
用于治疗静脉功能不全的浅表静脉和穿支静脉射频消融术已成为传统静脉剥脱术的主要替代方法。这种经皮技术使用局部麻醉或镇静，可在不到一小时内完成。VNUS闭合导管（VNUS医疗技术公司，加利福尼亚州圣何塞）通过静脉壁的电阻加热起作用，通过反馈回路持续监测至VNUS闭合发生器。其副作用比其他静脉内消融技术少，患者可立即恢复正常活动。新型ClosureFAST导管是一项重要进展，它结合了静脉内激光消融的速度和射频消融预期较少的副作用。
