[Embolization of drainage veins used in sclerotherapy of hemangiomas].

To improve the result of sclerotherapy for hemangiomas, the drainage veins of hemangiomas were embolized by injecting 95% alcohol into the hemangioma cavities. Alcohol injected into the cavity had to drain away through the vein of hemangioma and result in damage of the endothelial cells, and thrombosis on the venous wall, then the drainage vein is embolized. With the result of embolization of the drainage vein, the sclerosant solution injected into the hemangioma cavity cannot flow off any more. The sclerosant solution got much time to bring drug action into play, so the curative effect was raised. 30 patients including 24 cavernous hemangiomas and 6 mixed hemangiomas were treated with this method. 15 cases were cured, 11 cases were effective and 4 cases were ineffective. The effective rate was 86.7%.
