Efficacy of doxycycline and sodium tetradecyl sulfate sclerotherapy in pediatric head and neck lymphatic malformations

Abstract

ObjectivesLymphatic malformations are congenital vascular anomalies that occur from abnormal development of the lymphatic channels. Studies have shown that sclerotherapy can be a reliable alternative to surgery. The purpose of this retrospective study is to evaluate the safety and efficacy of percutaneous sclerotherapy with doxycycline and 3% Sotradecol as primary treatment for pediatric head and neck LMs, and to assess outcomes based on lesion classification, location and sclerosant used. Study designThis study was a single center, retrospective, case series study. Materials and methodsThe medical records of 38 children who underwent percutaneous sclerotherapy of LMs in the head and neck region at our tertiary care center between 1/1/2006 and 1/31/2011 were reviewed. A mean average of 2.9 (range 1–10) sclerotherapy sessions per child were performed. LMs involved primarily the face (61.3%), posterior neck (48.4%), submental area (45.2%), and anterior neck (35.5%). ResultsTwenty-nine subjects had adequate follow-up data, with 51.7% demonstrating complete resolution, 27.6% moderate improvement, and 20.7% no response. There was no significant difference in the outcome based on the sclerosant agent used or location of the lesion. Lesion type did affect outcome and macrocystic lesions were found to have a significantly higher resolution rate (95.2%) than microcystic or mixed lesions (p<0.05). The total number of complications was similar between agents and all were minor. ConclusionOur results indicate that percutaneous therapy with doxycycline and Sotradecol is safe and effective for children with LMs of the head and neck. Better outcomes were observed with macrocystic LMs. Level of evidence4.
