摘要
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。
The
authors consecutively operated on 34 cases of parasellar and suprasellar menin-giomas with
microsurgical techniques, and found that the tumor blood supplies were mainlyfrom the internal
carotid arteries. According to direct observations of the feeding arterial ori-gins under operative
microscope and the tumor vascularity after coagulation of the middlemeningeal arteries,their
blood supplies could be divided into 4 types except 2 cases of sphe-no-petro clival
meningiomas:Type Ⅰ,the blood dominantly came from ECA in 2 cases(6. 3%);Type Ⅱ,the
blood from either ECA or ICA was roughly equal in 5 cases(15.6%);Type Ⅲ, the blood was
dominantly from ICA in l8 cases(56.1%);Type Ⅳ,the blood wasonly from ICA in 7
cases(2l.9%).The closer the meningioma was located to the midline,the more predominant the
blood supply from internal carotid arteries was. The blood supplydominantly coming from ECA
was only observed in parasellar meningiomas.
