The role of precentral cerebellar vein in neurosurgery: An in-depth review of anatomy, implications, and risks.

Background: The Precentral Cerebellar Vein (PCV) plays a crucial role as an anatomical landmark in neurosurgery, and the possibility of its safe sacrifice is controversial. Understanding its anatomical nuances and clinical implications is fundamental in enhancing neurosurgical practice.

Methods: A systematic review following PRISMA guidelines was conducted to consolidate literature on the PCV.

Mapping the circle of Trolard: A holistic view of its role in neurosurgical practice, anatomical perspectives and clinical applications.

Introduction: An anatomical structure that resembles the circle of Willis, the circle of Trolard is generated in the basal cistern and travels around the midbrain in a roundabout manner, passing adjacent to the lateral side of the cerebral peduncle.

Research Question: The primary objective of this article is to provide neurosurgeons with a comprehensive understanding of Trolard's circle, emphasizing its anatomical features and clinical significance.

Material And Methods: A comprehensive evaluation of the available literature pertaining to the venous circle of Trolard was conducted by conducting searches in the PubMed, Web of Science, and Scopus databases.

The artery of Wollschlaeger and Wollschlaeger.

Introduction: The artery of Wollschlaeger and Wollschlaeger (AWW), named after the German neuroradiologists who discovered it, is a unique and remarkable anatomical structure. This review will delve deeper into the intricate details of the AWW its origin, significance, and the studies associated with it.

Methods: A comprehensive evaluation of the available literature on the AWW was conducted by doing searches on reputable academic databases such as PubMed, Google Scholar, and Web of Science.
