Varicose veins are the prevalent vascular disorder that has conventionally been managed via risky postoperative wound infections and conventional surgery. While ultrasound‐guided microwave ablation (UMA) has gained attention as a minimally invasive alternative, there is still a lack of research examining its comparative effectiveness. A prospective comparative investigation was undertaken in the Zhejiang region of China from January to November 2023, involving 140 patients who had received the diagnosis of primary varicose veins. An equal number of 70 patients underwent UMA and conventional surgery. Exclusion criteria for the study encompassed adult patients aged 18–65, with the exception of those who had undergone prior venous surgery, deep vein thrombosis or peripheral arterial disease. The demographical characteristics, procedural details and complication profiles of patients who developed postoperative wound infections within 30 days were analysed statistically. The outcomes demonstrated that postoperative wound infections were significantly diminished (5.7%) with UMA in comparison to conventional surgery (17.1%). In addition, the average duration of procedures and length of hospital stay for UMA patients were both reduced, although neither of these differences was found to be statistically significant (p > 0.05). Infection management, age and gender distribution of varicose veins were comparable between the two groups (p > 0.05). A significant inverse correlation was observed between the severity of varicose veins and postoperative outcomes, as determined by the regression analysis (p < 0.05). Using UMA to treat varicose veins showed promise as an alternative to conventional surgery, specifically in minimizing the incidence of postoperative wound infections. Additional research and clinical consideration are needed regarding the potential transition toward minimally invasive techniques in treatment of varicose veins, as suggested by these results.
