Letter to the Editor in Response to Long-Term Results of Radiofrequency Ablation for Unilateral Great Saphenous Vein Insufficiency and Hemodynamic Changes in the Contralateral Leg.

Abstract

We commend the authors for their valuable contribution on the long-term outcomes of radiofrequency ablation (RFA) in unilateral great saphenous vein insufficiency and its hemodynamic effects on the contralateral limb. While the study provides meaningful data, we highlight several methodological concerns, including limited ethnic diversity, unexplored causes of recanalization, high loss to follow-up, and potential observer bias. To enhance the clarity and generalizability of the findings, we pose specific questions to the authors regarding these aspects. Addressing these concerns may help reinforce the reliability and applicability of the study's conclusions in broader clinical contexts.
