Abstract：
OBJECTIVE: This article presents a comprehensive exploration of neurovascular anatomy of the encephalon, focusing specifically on the intricate network within the posterior circulation and the posterior fossa anatomy; enhancing understanding of its dynamics, essential for practitioners in neurosurgery and neurology areas.
METHODS: A profound literature review was conducted by searching the PubMed and Google Scholar databases using main keywords related to neurovascular anatomy. The selected literature was meticulously scrutinized. Throughout the screening of pertinent papers, further articles or book chapters were obtained through additional assessment of the reference lists. Furthermore, four formalin-fixed, color latex-injected cadaveric specimens preserved in 70% ethanol solution were dissected under surgical microscope (Leica Microsystems Inc, 1700 Leider Ln, Buffalo Grove, IL 60089, USA), using microneurosurgical as well as standard instruments, and a high-speed surgical drill (Stryker Instruments 1941 Stryker Way Portage, MI 49002, USA). Ulterior anatomical dissection was performed.
RESULTS: Detailed examination of the basilar artery (BA), a common trunk formed by the union of the left and right vertebral arteries, denoted a tortuous course across the basilar sulcus. Emphasis is then placed on the Posterior Inferior Cerebellar Artery (PICA), Anterior Inferior Cerebellar Artery (AICA) and Superior Cerebellar Artery (SCA). Each artery\'s complex course through the posterior fossa, its divisions, and potential stroke-related syndromes are explored in detail. The Posterior Cerebral Artery (PCA) is subsequently unveiled. The posterior fossa venous system is explained, categorizing its channels. A retrograde exploration traces the venous drainage back to the internal jugular vein, unraveling its pathways.
CONCLUSIONS: This work serves as a succinct yet comprehensive guide, offering fundamental insights into neurovascular anatomy within the encephalon\'s posterior circulation. Intended for both novice physicians and seasoned neuroanatomists, the article aims to facilitate a more efficient clinical decision-making in neurosurgical and neurological practices.

摘要：
目的：本文对脑的神经血管解剖进行了全面探索，特别关注后循环和后颅窝解剖结构内的复杂网络；增强对其动力学的理解，对于神经外科和神经病学领域的从业者至关重要。
方法：通过使用与神经血管解剖学相关的主要关键词搜索PubMed和GoogleScholar数据库，进行了深入的文献综述。精选的文献经过仔细审查。在相关论文的筛选过程中，通过对参考列表的额外评估，获得了更多的文章或书籍章节。此外，四福尔马林固定，在手术显微镜下解剖保存在70%乙醇溶液中的彩色乳胶注射尸体标本(LeicaMicrosystemsInc，1700LeiderLn,布法罗格罗夫,IL60089,USA),使用微神经外科手术和标准器械，和高速手术钻(StrykerInstruments1941StrykerWayPortage，MI49002，美国）。进行了前部解剖解剖。
结果：基底动脉（BA）的详细检查，由左右椎动脉联合形成的共同主干，表示穿过基底沟的曲折路线。然后将重点放在小脑后下动脉（PICA）上，小脑前下动脉（AICA）和小脑上动脉（SCA）。每条动脉穿过后颅窝的复杂过程，它的分裂，并详细探讨了潜在的卒中相关综合征。大脑后动脉（PCA）随后亮相。后颅窝静脉系统的解释，对频道进行分类。逆行探查追踪静脉引流回到颈内静脉，解开它的路径。
结论：这项工作是一个简洁而全面的指南，提供脑后循环神经血管解剖学的基本见解。适合新手医生和经验丰富的神经解剖学专家，本文旨在促进神经外科和神经科实践中更有效的临床决策。
