[The treatment of maxillofacial hemangioma with transcatheter embolization].

Preliminary experience obtained from 7 cases with maxillofacial hemangioma treated with the external carotid arterial transcatheter embolization is presented. Of the 7 cases 2 were diagnosed as racemose hemangioma, 1 case as cavernous hemangioma and 4 cases as central mandibular and zygomatic arch cavernous hemangioma. External carotid arterial transcatheter embolization was adopted as radical treatment of hemangioma in 3 cases. Of them, excellent result was achieved in 1 case, and good in 2. Embolization was used as preoperative preparation for the treatment of hemangioma in 2 cases. Two operations were successfully performed and the results of hemostasis were excellent during the operation. The arterial transcatheter was all performed with Seldinger technique and through transfemoral approach. The embolization agents used included gel form, absolute ethanol, medical TH glue, sodium morrhuate, etc. The advantages of this method, and the relationships between the properties of the embolization agents and the effect of embolization, the physiological function of the target organ and the complication are discussed and evaluated.
