To evaluate the clinical efficacy of vascular embolization combined with body surface injection of sclerosing agent for the treatment of high-flow hemangiomas in children.

A total of 38 cases were enrolled in the study, including 28 cases with maxillofacial hemangiomas, 10 cases with limbs hemangiomas, and 6 cases with upper limb hemangiomas. The treatment plans were as follows: PVA with iodinated oil in 11 cases, PVA with bleomycin in 5 cases, and PVA with iodinated oil and bleomycin in 22 cases. A foam sclerosing agent mixture (bleomycin+1 ml add polyol+4 ml add air+1 ml dexamethasone+1 ml contrast medium) was injected into the angioma through the surface, and the involuting condition and related complication were recorded.

There was no complication in all patients, among which 18 children’s hemangiomas faded away in regular follow-up after one treatment, 13 children’s hemangiomas partly faded away and local symptom disappeared in regular follow-up after transcatheter arterial embolization combined with body surface injection sclerotherapy, 4 children's hemangiomas faded away after body surface injection sclerotherapy for two or three times, 3 children's hemangiomas size decreased after transcatheter arterial embolization, 1 child loss to follow-up, 1 child went to sugery therapy, and 1 child was with drug therapy.

Transcatheter arterial embolization combined with body surface injection sclerotherapy is an important method which could be the preferred treatment in high-flow hemangiomas in children.
