Radiofrequency Ablation and Concomitant Sclerotherapy for the Treatment of Varicose Veins (VV): Perspectives from a Developing Country

Objectives/Background: With decreased patient downtime and reduction in health expenditures, endovascular treatments have become popular for the treatment of venous insufficiency. In this study, we assessed the outcomes of using radiofrequency ablation (RFA) and sclerotherapy for refluxing veins and incompetent perforators in a developing country.

Materials and Methods: Subjects were selected from an ongoing registry from October 15, 2015 to April 5, 2018. Patients were followed up until 6 months. Pre- and post-procedural Clinical, Etiologic, Anatomic, and Pathophysiologic (CEAP) scores were compared, and complications were documented and treated accordingly.

Results: In total, 102 limbs (n=97) with 76 great saphenous veins (GSVs) and 26 small saphenous veins (SSVs) underwent RFA, with 79% undergoing concomitant sclerotherapy. Mean follow-up time was 188 days (±33.16). Moreover, 59% were males and 41% females. At the end of follow-up, 99% of the legs had complete occlusion. Pre- and post-procedural CEAP scores were 4.21±1.5 and 3.36±1.7, respectively (p-value <0.001). Endovenous heat-induced thrombosis (EHIT) types 1, 2, 3, and 4 were found in 8.8%, 3.9%, 1.9%, and 0% of the legs, respectively. Most common complications were pain and tenderness (51%), bruising (18%), and paresthesia (7%).

Conclusion: RFA and sclerotherapy have proved to be safe and efficacious. Computed tomography (CT) venous mapping aids in delineating complex venous anatomy and in ruling out deep vein thrombosis (DVT) in cases with discrepancy on Doppler ultrasound. Strict compliance of procedural and post-procedural protocol can assure promising results and futuristic value.
