[The preoperative application of selective catheterization and embolism of the external carotid artery in treating tumors with enriched blood supply in the base of skull].
OBJECTIVE
Embolizing the feeding vessels of the tumors with enriched blood supply in the base of skull in order to reduce the bleeding during operation.


METHODS
Under digital subtraction angiographic control, superselectively catheterizing the external carotid artery, thus occluding the terminal branches of the feeding arteries of the tumor with particles of liquidized gelfoam.


RESULTS
Nine cases studied showed that the angiography of the feeding vessels of the tumor disappeared relatively. The bleeding decreased significantly during operation. The postoperative pathological findings showed that the entity of the tumor was congested with gelfoam.


CONCLUSIONS
After figuring out the blood supply of the tumor, superselective catheterization of the external carotid artery followed by occlusion of the feeding vessels can reduce the size of the tumor and diminish the bleeding during operation, thus can improve the safety of the operation. It should be one of the crucial preoperation measures.
