Comparison of the effect of combination therapies in the treatment of large varicose ulcers: A real-world cohort study

Objectives:The primary treatment for varicose ulcers is to address the underlying cause of venous hypertension, additionally, split-thickness skin transplantation (ST) is an effective option for large ulcers. The aim of this study was to compare the efficacy of venous surgery with or without split-thickness ST in the management of varicose ulcers (diameter ≥6 cm).Methods:Patients with varicose ulcers between 2013 and 2023 were included in the real-world retrospective cohort study. The endovenous microwave ablation/endovenous laser ablation-high ligation-foam sclerotherapy-compression therapy + ST group (EMA/EVLA-CT-HL-FS + ST) consisted of 32 patients, while the EMA/EVLA-CT-HL-FS group consisted of 48 patients.Results:A difference in ulcer healing time was found between the two groups (the hazard ratio [HR] was 4.4, 95% CI [2.3–8.2], P < 0.0001). However, the healing rate did not differ between the two groups at 6 and 12 months postoperatively.Conclusion:ST has been shown to expedite ulcer healing and ameliorate the symptoms of VVs in the early stages of treatment, while its intermediate to long-term efficacy for ulcer healing and overall patient quality of life may be limited.
