Lower extremity varicose veins(LEVV)are a common vascular disorder.Emerging evidence suggests that ultrasound-guided microwave ablation(UGMA)is an effective treatment modality for this condition.This minimally invasive technique closes affected veins via leveraging the thermal effects generated from microwave energy.Multiple clinical researches have highlighted its high success rate,low complication rate,rapid postopera-tive recovery,and significant improvement in patient's quality of life,particularly among those with C2-C6 stage disease and larger great saphenous vein diameters.Compared with traditional open surgeries and other minimally invasive techniques,UGMA demonstrates superior therapeutic efficacy,safety,and patient satisfaction.This review elucidates the physical principles,operational essentials,and clinical progress of UGMA,exploring its strengths and challenges in LEVV management.Despite current hurdles like high equipment costs and strict operation standards,UGMA holds a promising future and may potentially offer safer and more effective treatment options for LEVV.
