This study examined the impact of body weight on the effectiveness and safety of endovenous thermal ablation (ETA) for the treatment of symptomatic varicose veins. The results showed that obese patients experienced prolonged pain and higher infection rates after ETA, but the effectiveness and safety of ETA for varicose vein treatment were independent of the patient's body weight.
Objective: This study aimed to examine whether body weight may affect the effectiveness and safety of endovenous thermal ablation (ETA) for the treatment of symptomatic varicose veins. Methods: This retrospective single-center cohort study analyzed the outcomes and patient demographic data with a focus on the body weight of all patients who had ETA of symptomatic varicose veins between September 2017 and October 2020. Results: A total of 1178 treated truncal veins from 636 patients were analyzed. The mean +/- standard deviation body mass index (BMI) was 25.5 +/- 4.9. In 2.3% of cases, the patients were underweight (BMI < 18.5), 31.0% were overweight (BMI > 25), and 16.6% were obese (BMI > 30). Complete truncal occlusion was observed 1 year post intervention in 97.6-100% and patients were satisfied or very satisfied in 96.2-100% across BMI groups. Pain was low but significantly higher in the patients with obesity 6 weeks post intervention (visual analog scale 0.84 +/- 1.49) and a higher infection rate was observed in the patients with obesity (n = 4/132; 3.0%). No significant association was observed between BMI and bleeding or thromboembolic events. Conclusions: Patients with obesity experienced prolonged pain and more infections after ETA, but ETA for varicose vein treatment remains effective and safe, independent of the patient's BMI.
