To explore interventional treatment methods and therapeutic effects of interventional therapy for hepatic hemangioma in children.

The clinical data of 31 children underwent interventional therapy for hepatic hemangioma in Beijing Children's Hospital from January 2016 to January 2019 were retrospectively analyzed. The patients are ranging in age from 6 days to 9 years old. Including 26 cases of congenital hepatic hemangiomas, 5 cases of infantile hepatic hemangiomas, and imaging examination showed 5 cases of multiple liver lesions and 26 cases of single liver lesions. All children received plain CT scan, enhanced CT scan and embolization sclerotherapy for hepatic hemangioma. CT findings before and after interventional embolization were used to analyze the efficacy of embolization sclerotherapy for hepatic hemangioma in different types of children. The paired sample t test was used to compare the volume differences of the infantile and congenital hemangioma lesions before and after interventional therapy.

23 cases received single interventional therapy, 6 received two interventional therapy, and2 received three interventional therapy. 26 cases in total 31 patients were followed up, including 23 congenital hepatic hemangioma and 3 infant hepatic hemangioma. The tumors disappeared completely in 11 children and the children recovered completely, while the tumors were partially reduced in 15 children (4 cases reduced by more than 70%, the effect was significant; 6 cases reduced by 30%~50%, partially effective; 5 cases reduced less than 30%, the effect was not obvious). The mean preoperative and postoperative volumes of congenital hemangioma were (161.86 ± 21.40) cm³ and (41.46 ± 9.73) cm³, and the mean preoperative and postoperative volumes of infantile hemangioma were (22.73 ± 1.92) cm³ and (11.18 ± 3.18) cm³. The preoperative and postoperative volume differences for congenital hemangioma and infantile hemangioma were all statistically significant (P < 0.001).

Embolization sclerotherapy of hepatic hemangioma is a safe and effective minimally invasive treatment for hepatic hemangioma in children,and preoperative classification is an important factor in the efficacy of interventional therapy for pediatric hepatic hemangioma in children.
