[Embolotherapy of craniofacial tumors and vascular diseases: assessing the effect of different embolic agents].

To assess the effect of different embolic agents in curing craniofacial tumors and vascular diseases, 21 patients who were treated by intra-arterial embolization were divided into three groups: gelfoams, bletilla striatas and coils. The results showed that 8 cases of preoperative patients in gelfoams group had a good effect and bleeding were reduced during operation. One patient had vascular recanalization at 1 month after embolization with gelfoam. All patients in bletilla striatas had ideal effect. In coils group, collateral supplying arteries were found in 3 patients at once after embolization and the others had a good effect. In conclusion, craniofacial tumors and vascular diseases were fit to embolotherapy. The selection of embolic agents should be gelfoam in preoperative embolization and bletilla striata in palliative treatment There were not severe complications.
