摘要
对７０例蝶骨嵴脑膜瘤的脑血管造影数字减影进行分析。颈外动脉系统供血占２４％，颈内动脉系统供血占２０％，双重供血占３６％，供血血管不明确占２０％。在颈外系统中参与供血最多的动脉是硬脑膜中动脉、圆孔动脉。在颈内系统中是眼动脉的分支、脑膜垂体于和大脑中动脉的分支。通过采用术前颈外动脉结扎的方法以控制和减少手术过程中的出血。１９例中，肿瘤全切和近全切除达７４％。提示，颈外动脉结扎取得最好效果的是直径＜７ｃｍ、富血管性的，以颈外动脉供血为主的大型蝶骨嵴脑膜瘤。
Abstract Seventy brain digital subtraction angiography (DSA) were done on 70 cases of sphenoid ridge meningioma 17 meningiomas are supplied solely by the external carotid artery:14 by internal carotid artery, and 25 by the both arteries. The other 14 of which the feeding artery are not recognized . Most of the feeding arteries that derived from external carotid artery are the middle meningeal artery and artery of foramen rotundum. Feeders derived from internal carotid artery are the branches of ophthalmic artery, meningohypophyseal trunk and middle cerebral artery.19 cases underwent preoperative ligation of the external carotid artery for reducing operative bleeding. Total and subtotal removal of tumors accomplished in 74%. In this series,the best results were obtained from tumors which supplied mainly by the external carotedartery and the tumor size within 7cm im diameter.
