Radio-opaque ethylcellulose-ethanol is a safe and efficient sclerosing agent for venous malformations

Objective To evaluate the efficacy and safety of gelified ethanol, a newly developed sclerosing agent for slow-flow vascular malformations. Methods Seventy-nine sclerotherapy procedures were performed on 44 patients with 37 venous malformations, 2 glomuvenous malformations, 2 lymphatic malformations, 2 lymphatico-venous malformations, and 1 Klippel-Trenaunay syndrome. The median injected volume was 1.00 mL/site of injection. Effects of sclerotherapy on pain, functional and cosmetic disturbance were statistically evaluated with a final result score. Local and systemic complications were recorded. Results The mean Visual Analogue Scores were 5.20 ± 2.81 before and 1.52 ± 1.25 after treatment ( p
