“…Additionally, there are crucial collaterals to be found, which will be detailed shortly. At its end, the Basilar Artery terminates at a bifurcation right in front of the pontomesencephalic sulcus, point in which it gives off its two symmetrical terminal branches: the left and right posterior cerebral arteries, at the level of the interpeduncular cistern [ 25 ]. This division is also known as Basilar Apex or “Basilar tip”, which may be situated at the exact same level, above, or beneath the superior border of the dorsum sellae, towards the prepontine cistern.…”

“…This division is also known as Basilar Apex or “Basilar tip”, which may be situated at the exact same level, above, or beneath the superior border of the dorsum sellae, towards the prepontine cistern. In cases where the basilar bifurcation lies above the dorsum sellae or below it, they are designated as high-riding or low-riding basilar tips, respectively, having different implications regarding the surgical approach of choice [ 7 , 11 , 25 , 35 ]. Basilar lesions, such as injury due to arterial wall dissection can lead to a broad assortment of gravely severe outcomes, ranging from many brainstem alternate syndromes to the dreaded Locked-in Syndrome [ 10 , 12 , 16 ].…”

“…This is particularly evident in the posterior cranial fossa or craniovertebral junction, where reduced spatial compliance can pose challenges [ 14 , 52 ]. The effective management of these lesions, whether through surgical or endovascular interventions, heavily depends on a comprehensive understanding of the normal neurovascular anatomy of the posterior circulation [ 24 , 25 , 32 ]. Additionally, knowledge of the cisternal anatomy in the infratentorial region and its proximity to cranial nerves is crucial in surgical procedures, as these serve as corridors and landmarks for accessing specific segments of the vertebrobasilar system [ 20 , 25 , 48 , 50 ].…”

Purpose 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. Method 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. Conclusion 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.
