【摘要】：目的研究桥小脑角区血管神经间的解剖关系,为临床微血管减压术提供解剖学资料。方法20例10%甲醛固定并灌有乳胶的成人头颅湿标本,去除大脑半球、小脑幕和模拟临床枕下乙状窦后手术入路,逐层解剖、观察、照相。方法桥小脑角区上血管神经复合体主要包括滑车神经、三叉神经和小脑上动脉、小脑下前动脉、岩上静脉、岩上窦等。小脑上动脉主干尾袢及其分叉部附近常压迫三叉神经出入脑干区的上方。中血管神经复合体主要包括展神经、面听神经和小脑下前动脉、小脑下后动脉等。小脑下前动脉常呈折叠状凸入内耳,在折叠端及其附近常发出内听动脉入内耳。下血管神经复合体主要包括延髓、后组颅神经、舌下神经、小脑下后动脉、椎动脉等。结论责任血管可能不止一根,压迫点可能不止一处,详尽的解剖研究可提高显微血管减压手术的成功率。
[Abstract]:Objective to study the anatomical relationship between blood vessels and nerves in cerebellopontine angle region and to provide anatomical data for clinical microvascular decompression. Methods 20 cases of adult head wet specimens fixed with 10% formaldehyde and latex were removed from cerebral hemisphere, cerebellar tentorium and simulated posterior occipital sigmoid sinus approach, dissected layer by layer, observed and photographed. Methods the superior vascular nerve complex in cerebellopontine angle mainly included trocar nerve, trigeminal nerve and superior cerebellar artery, anterior inferior cerebellar artery, superior petrosal vein, superior petrosal sinus and so on. The trigeminal nerve is often pressed into and out of the upper part of the trunk and trunk of the superior cerebellar artery near the tail loop and its bifurcation. The middle vascular nerve complex mainly includes abductor nerve, facial auditory nerve and anterior inferior cerebellar artery, posterior inferior cerebellar artery and so on. The anterior inferior cerebellar artery is often folded into the inner ear, and the inner auditory artery is often sent into the inner ear at and near the folded end. The inferior vascular nerve complex mainly includes medulla oblongata, posterior group skull nerve, hypoglossal nerve, inferior cerebellar posterior artery, vertebral artery and so on. Conclusion there may be more than one responsible vessel and more than one compression point. Detailed anatomical study can improve the success rate of microvascular decompression.
