摘　　要：目的研究后交通动脉池(PCoA池)及周围脑池与相关蛛网膜的显微解剖特点,并探讨其临床意义。方法显微镜下对10例福尔马林固定的尸头标本进行解剖,观察PCoA池及周围脑池与相关蛛网膜的显微特点并录像记录。结果 PCoA池为一个独立存在脑池,本组出现12侧(60%)。其前方是颈内动脉池,本组出现20侧(100%);下外侧是动眼神经池,本组出现20侧(100%);内侧为非对称脚间池,本组出现10侧(100%);后外侧为环池,本组出现20侧(100%)。分隔颈内动脉池与PCoA池为后交通膜,本组出现12侧(60%);分隔动眼神经池与PCoA池为Liliequist膜,本组出现10例(100%);分隔脚间池与PCoA池为Liliequist膜侧壁;分隔环池与PCoA池为环中脑膜前部发出的蛛网膜小梁。结论 PCoA池及其周围脑池是基底脑池的重要组成部分,了解基底脑池与相关蛛网膜结构对于了解此区的病变和手术具有重要意义。Objective To study the anatomical features of the posterior communicating artery（PCoA） cistern,surrounding cisterns and their related arachnoid membranes and discuss the clinical significance of these structures.Methods The microanatomical study was performed in 10 formalin-fixed cadaveric head specimens under microscope.The PCoA cistern,surrounding cisterns and related arachnoid membranes were observed,photographed and videotaped during the surgical procedure.Results The PCoA cistern existed independently in 12 sides（60%）.The internal carotid artery（ICA） cistern was at the anterior of the PCoA cistern in 20 sides（100%）,oculomotorius cistern was in the lateral-inferior side of the PCoA cistern in 20 sides（100%）,asymmetric interpeduncular cisterns was in the inside in 10 sides（100%）,ambient cistern was in the posterior-lateral part in 20 sides（100%）.The ICA cistern and PCoA cistern were separated by the posterior communicating membrane in 12 sides（60%）,oculomotorius cistern and PCoA cistern were separated by Liliequist membrane in 10 cases（100%）,the interpeduncular cistern and PCoA cistern were separated by the lateral part of Liliequist membrane,ambient cistern and PCoA cistern were separated by arachnoid trabeculae of perimesencephalic membranes.Conclusions The PCoA cistern and its surrounding cisterns are important parts of the basal cisterns.Understanding the cisterns and the related structures of arachnoid membrane are of important significance for realizing the diseases and operations in the region.
