Treatment of varicose great saphenous vein with endovenous laser alone or combined with eco-guided foam sclerotherapy: A randomized controlled trial

Objectives: This study compares Endovenous Laser Ablation (EVLA) alone versus combined with ultrasound-guided foam sclerotherapy (UGFS) for Great Saphenous Vein (GSV) insufficiency. Methods: Sixty patients were randomly allocated to EVLA or EVLA-UGFS groups which focused on GSV occlusion rates, complications, additional treatments, and quality of life (QoL) changes. Results: Among 55 participants, the EVLA group had higher 12-month occlusion rates (92.3% vs. 75.8%, p = 0.11). Nervous injury (NI) was rarer in EVLA-UGFS (3.4% vs. 23.1%, p = 0.04). No significant difference in other complication rates (p > 0.05). QoL improved in both groups (p < 0.001). EVLA-UGFS required more subsequent procedures (24.1% vs. 7.7%, p = 0.03). Conclusions: EVLA and EVLA-UGFS effectively treat GSV insufficiency, enhancing QoL. The combined method reduces NI risk but may require more follow-up procedures.
