Chronic venous insufficiency (CVI) is the most common vascular disease and represents a significant health care problem in the United States. Reflux of the great saphenous vein is the most common cause of this condition, whose symptoms include varicose veins, leg swelling, skin discoloration, and ulceration. The traditional treatment of this condition is saphenofemoral ligation with stripping of the saphenous vein followed by varicose vein removal, if necessary. Recent advances in minimally invasive endovenous therapy have led to the development of catheter-based radiofrequency ablation (RFA) of the saphenous vein, which has gained an increasing acceptance in clinical practice. Endovenous RFA was introduced into clinical practice in Europe in 1998 and in the United States in 1999. Since then, over 250,000 procedures have been performed worldwide. Procedure safety and efficacy are well understood, with over 60 publications on the subject in the peer review literature, including four randomized trials comparing this technology with traditional vein stripping surgery. With the advent of tumescent anesthesia, the majority of RFA procedures are now performed in an office setting. This article examines the current technology using RFA in saphenous vein ablation with the Closure catheter system. Procedural techniques and clinical outcome using RFA in saphenous vein ablation are discussed. Clinical data comparing RFA versus saphenous vein stripping are also examined. Lastly, the clinical utility of a new RFA catheter, ClosureFAST, is discussed. ClosureFAST is a new generation of RFA catheter and has exhibited significant improvement in the ease of use and the procedure speed over the previous generation catheters while maintaining the favorable patient recovery profile seen with the RFA technology.
慢性静脉功能不全(CVI)是最常见的血管疾病,在美国是一个重大的医疗保健问题。大隐静脉反流是导致这种疾病的最常见原因,其症状包括静脉曲张、腿部肿胀、皮肤变色和溃疡。这种疾病的传统治疗方法是大隐静脉高位结扎并剥脱大隐静脉,必要时切除静脉曲张。微创腔内治疗的最新进展导致了基于导管的大隐静脉射频消融(RFA)技术的发展,该技术在临床实践中越来越被接受。腔内RFA于1998年在欧洲引入临床实践,1999年在美国引入。从那时起,全球已进行了超过25万例手术。手术的安全性和有效性已得到充分了解,同行评审文献中有60多篇关于该主题的出版物,包括四项将该技术与传统静脉剥脱手术进行比较的随机试验。随着肿胀麻醉的出现,现在大多数RFA手术都在门诊进行。本文探讨了使用Closure导管系统进行大隐静脉消融的RFA当前技术。讨论了在大隐静脉消融中使用RFA的手术技术和临床结果。还研究了比较RFA与大隐静脉剥脱的临床数据。最后,讨论了一种新型RFA导管ClosureFAST的临床应用。ClosureFAST是新一代RFA导管,在易用性和手术速度方面比上一代导管有显著改进,同时保持了RFA技术所见的良好患者恢复情况。
