Abstract

Abstract: PURPOSE: To explore the DSA classification and treatment strategy of tongue venous malformation. METHODS: From February 2016 to February 2019, the DSA manifestations of 132 cases with venous malformations of the tongue were summarized. They were classified into 4 types according to imaging characteristics: typeⅠ(non-drainage type), typeⅡ(lower- drainage type), type Ⅲ (higher-drainage type), type Ⅳ(extensive type). Different therapeutic schemes were selected according to the types. The non- drainage type was treated with pingyangmycin alone, the lower-drainage type was treated with lauromacrogol foam alone, the higher- drainage type was treated with absolute alcohol combined with lauromacrogol foam, the extensive type was treated as higher-drainage type first and then combined with plastic resection. Among the cases, therapeutic effects and adverse reactions of each group were recorded and compared. RESULTS: One hundred and thirty-two cases in this study were followed up for 12 to 41 months with an average of 15.8 months. After sclerosing therapy, the venous malformations of the tongue of all patients significantly reduced or even disappeared. Type Ⅰincluded 8 cases with an efficiency of 100%, type Ⅱ included 17 cases with an efficiency of 100%, type Ⅲ included 98 cases with an efficiency of 90.8%, typeⅣincluded 9 cases, with an efficiency of 77.8%.The main adverse reactions were tissue necrosis: 0 in typeⅠ, 1(5.88%) in typeⅡ, 16(16.33%) in type Ⅲ, and 7(77.78%) in type Ⅳ. CONCLUSIONS: The classification of venous malformations of the tongue based on DSA is significant and valuable in guiding clinical treatment. The majority of tongue venous malformations are type Ⅲ, and the smallest propotion is type Ⅰ. Transmucosal sclerotherapy with absolute ethanol is of significance for the treatment of venous malformations of the tongue classified in type Ⅲ and type Ⅳ.
