Office Based Endovenous Radiofrequency Ablation of Truncal Veins: A Case for Moving Varicose Vein Treatment out of Operating Theatres

Abstract

This study aims to assess the efficacy and outcomes at one year after office based endovenous radiofrequency ablation (OBEVRFA) as a standalone procedure for varicose veins under local anaesthesia. A retrospective study of prospectively collected data of all OBEVRFAs done in the vascular unit from April 2014 to June 2016 was performed. The demographics, clinical findings, initial venous duplex ultrasound (DUS) findings, the vein ablated, and immediate complications were recorded. Patients were reviewed at six weeks and again if necessary with or without a repeat DUS. The follow up period ranged from 12 to 38 months. Patients undergoing further procedures for symptomatic residual veins within the follow up period were recorded. Average cost and income were obtained from the hospital Patient Level Information and Costing Systems data. A total of 523 limbs were listed for OBEVRFA during the study period. Ninety-four (18%) were cancelled on the day of surgery for various reasons. A total of 429 procedures in 394 patients were performed. There were 35 bilateral cases; each limb performed on separate occasions. The female to male ratio was 1.2:1. The median age was 54 years (range 17-88 years). The CEAP (Clinical, Etiologic, Anatomic and Pathophysiologic) classification was C2 to C3, 291 (68%); C4 to C5, 11 (26%), and C6, 26 (6%). Forty-seven (11%) recurrent varicose veins were treated. There were three recorded cases of endovenous heat induced thrombosis (EHIT). Sixty (14%) patients were lost to follow up. One hundred and five (29%) patients underwent repeat DUS for persistent symptoms. In the follow up period, only 86 patients (23%) needed further multiple avulsions. OBEVRFAs of the truncal veins for the treatment of varicose veins is safe and effective and could be performed in all suitable patients to free up theatre capacity.
