Endovenous thermal and non‐thermal therapeutic approaches have become standard of care for the treatment of venous insufficiency. However, comparative studies on its use in the population of venous leg ulcer patients are scarce. The present study aimed at a comparison of the efficacy of endovenous laser ablation (EVLA) and ultrasound‐guided foam sclerotherapy (UGFS) for the treatment of venous leg ulcers (VUs). We retrospectively analyzed patient records of 68 patients with active VUs (C6 of the CEAP‐classification), who underwent EVLA (n = 33) or UGFS (n = 35) between January 2001 and January 2021. In 68 patients, 97 venous segments (GSV: 43, SSV: 17, NSV: 37) were treated. Ulcer surface area at initial presentation did not differ significantly between both treatment groups (EVLA: 7.7 ± 10.7 vs. UGFS: 8.5 ± 16.3 cm2; p = 0.73). No significant difference regarding patient characteristics was found, with the exception of age, as patients receiving UGFS treatment were significantly older (EVLA: 61 ± 17 vs. UGFS: 70 ± 14 years; p = 0.018). The rate of ulcer resolution was not significantly different between EVLA and UGFS groups (97.0% vs. 85.7%; p = 0.20). Also, the mean time to complete ulcer healing after endovenous intervention was comparable (EVLA: 59 ± 37 vs. UGFS: 63 ± 41 days; p = 0.68). However, the relapse rate was significantly higher for UGFS than for EVLA treated patients (31.4% vs. 3.0%; p = 0.002). Taken together, rates of ulcer resolution and ulcer healing time after endovenous intervention were comparable between both treatment modalities. Nevertheless, a significantly higher relapse rate was observed in UGFS treated patients.
