In recent years, minimally invasive endovenous treatments have gained popularity in the treatment of superficial venous reflux. The perceived advantages of endovenous therapy include reduced pain, high vein occlusion rates, and early return to work and normal activities. Endovenous radiofrequency ablation (RFA) involves the delivery of thermal energy from a bipolar catheter to the venous segment to be treated. This technique has been available since 1998 and numerous devices and catheters are now produced. Numerous prospective and randomized studies have compared the effectiveness of RFA with traditional and endovenous procedures. In this article, the available evidence for clinical effectiveness, quality of life and cost gains following endovenous RFA is summarized. The scientific principles behind RFA and technical procedural considerations are discussed and standards of care for the delivery of endovenous RFA are proposed.
近年来，微创静脉内治疗在浅表静脉反流的治疗中越来越受欢迎。静脉内治疗的公认优点包括疼痛减轻、静脉闭塞率高以及能早期恢复工作和正常活动。静脉内射频消融（RFA）涉及将热能从双极导管传递到待治疗的静脉段。自1998年以来就有这项技术，现在生产了许多设备和导管。众多前瞻性和随机研究比较了RFA与传统和静脉内手术的有效性。本文总结了静脉内RFA后临床有效性、生活质量和成本效益的现有证据。讨论了RFA背后的科学原理和技术操作注意事项，并提出了静脉内RFA的护理标准。
