鞍区脑池的显微外科解剖

目的 了解鞍区脑池的界限和相互毗邻关系。方法 采用显微外科技术解剖并观察鞍区脑池。结果 鞍区脑池包括颈内动脉池、后交通动脉池、颈内动脉—后交通动脉池、视交叉池、垂体池、终板池、Sylvian池近侧端、嗅池、脚间池、脚池和动眼神经池，小梁蛛网膜分隔各池。结论 ①鞍区脑池环绕视交叉池有序排列。②不同的手术入路或同一入路到达不同部位，所涉及的脑池及其解剖的方向和次序均不相同。

Microsurgical Anatomy of Subarachnoid Cisterns in Sellar Region

Objective To investigate the limit of the subarachnoid cisterns in the sellar region and anatomical relationshoip between it and the adjacent structure.Method The subarachnoid cisterns were studied by microsurgical technique.Results The subarachnoid cisterns in the sellar region include the internal carotid cistern,the posterior communicating cistern,the internal carotid and posterior communicating cistern,the chiasmatic cistern,the pituitary cistern,the olfactory cistern,the lamina terminalis cistern,Sylvian cistern,the interpeduncular cistern,the crural cistern and the oculomotor cistern.The chiasmatic cistern lies in the center and is circled by the other cisterns regularly.Conclusion The subarachnoid cisterns in the sellar region lie regularly.The subarachnoid cisterns should in turn be opened to obtain a mimimally invasive surgery corridor.The orders of incising the cisterns in different approaches are different.
