连续施行鞍上、鞍旁脑膜瘤显微外科切除术３４例，发现颈内动脉（ＩＣＡ）系为肿瘤的主要供血来源。除岩斜坡－蝶区脑膜瘤２例外，按手术显微镜下对肿瘤供血动脉的直接观察与电凝脑膜中动脉（ＭＭＡ）后肿瘤的血运状况，将其供血分四型：颈外动脉（ＥＣＡ）为主型２例（６．３％）；ＥＣＡ－ＩＣＡ供血相当型５例（１５．６％）；ＩＣＡ为主型１８例（５６．１％）；ＩＣＡ单独供血型７例（２１％）。肿瘤发生部愈近中线，ＩＣＡ供血趋势愈明显；ＥＣＡ主要供血者仅见于鞍旁型脑膜瘤。
Continuous implementation of suprasellar, parasellar meningiomas microsurgical resection in 34 cases found that the internal carotid artery (ICA) Department of the main source of blood for the tumor. In addition to the rock slope - butterfly meningioma in 2 cases, according to the direct observation of the tumor feeding artery under the microscope and the blood vessels of the tumor after electromagnetism and meningeal artery (MMA), the blood supply was divided into four types: external carotid artery (ECA ) Were predominant in 2 cases (6.3%), 5 cases (15.6%) were ECA-ICA, 18 cases were ICA (56.1%) and 7 cases (21% ). The neoplasm of the tumor was closer to the midline, and the trend of ICA blood supply was more obvious. The main blood donors of ECA were found only in the sella meningioma.
