LYMPHANGIOMAS IN CHILDREN - PERCUTANEOUS SCLEROTHERAPY WITH AN ALCOHOLIC SOLUTION OF ZEIN

PURPOSE: To determine the efficacy of percutaneous sclerotherapy with an alcoholic solution of zein in lymphangiomas in pediatric patients. MATERIALS AND METHODS: Fourteen patients with macrocystic and mixed ly mphangiomas were treated with use of Ethibloc as a sclerosing agent. T he procedure was performed with ultrasonographic and/or fluoroscopic g uidance. Follow-up clinical and sequential computed tomographic examin ations were performed to evaluate regression of the lesion. RESULTS: R egression was excellent in nine (64%) of the 14 lesions: Regression wa s complete in four lymphangiomas and was to less than 5% of the initia l volume in five. Satisfactory results were obtained in the remaining five (36%) of 14 lesions. The most frequent complication was leakage o f Ethibloc without important sequelae in 10 of the 14 lymphangiomas. C ONCLUSION: Percutaneous sclerotherapy with Ethibloc was a safe and eff ective procedure in the treatment of macrocystic and mixed lymphangiom as.
