Ethanol sclerotherapy of head and neck venous malformations

OBJECTIVE: This retrospective study evaluated the results of sclerotherapy with low doses of ethanol for treatment of head and neck venous malformations. METHODS: We treated 51 patients, 37 females. Median age was 23 years. Patients were treated with percutaneous intralesional injection of alcohol every two weeks and followed up prospectively for a median period of 18 months. Most lesions affected the face and cosmetic disfigurement was the most frequent complaint. RESULTS: We performed a median of 7 sessions of sclerotherapy. Complete resolution or improvement was observed in 48 patients presented. Five cases of small skin ulceration, two cases of hyperpigmentation and two of paresthesia were documented; all of them were treated conservatively. CONCLUSION: Percutaneous sclerotherapy with low doses of ethanol is a safe and effective treatment modality for venous malformations affecting the head and neck.
