Lauromacrogol foam injection under ultrasonic guidance for pediatric lip venous malformations

Objective To evaluate the efficacy and safety of lauromacrogol foam sclerotherapy in the treatment of children with lip venous malformation. Methods Fifty-two children (27 males and 25 females) aged from 6 months to 17 years with lip VM who underwent lauromacrogol foam injection with ultrasonic guidance from July 2018 to December 2020 in our hospital were retrospectively recruited for this study. All the children were examined by MRI, ultrasound, blood routine and coagulation before operation. We were guided by ultrasound to locate the blood flow area (nests), injecting lauromacrogol foam to fill the venous malformation. The follow-up time was 14.31 ± 5.96 (6–24) months. Follow-up items include clinical manifestations, imaging data, efficacy and complications. Results This group of children was treated 3–5 times, an average of 4 times/case. The total effective rate was 90.38%. Pain in 4 cases, fever in 4 cases, infection in 2 cases, ulcer in 1 case. There were no serious complications such as cardiopulmonary accident. Conclusion Ultrasound guiding foam sclerotherapy with lauromacrogol is effective and safe for children with lip venous malformation.
