    Area of Science:

    • Neurosurgery
    • Anatomy
    • Surgical Neurology

    Background:

    • Pineal and midbrain lesions present unique surgical challenges due to their deep anatomical location.
    • Understanding the intricate vascular anatomy, particularly the great vein of Galen, is crucial for safe surgical access.

    Purpose of the Study:

    • To demonstrate the most important surgical approaches for pineal and midbrain lesions.
    • To elucidate the anatomical peculiarities and potential pitfalls associated with these surgical corridors.
    • To emphasize the role of the great vein of Galen as a critical landmark and potential obstacle.

    Main Methods:

    • Anatomical studies using fresh and formalin-fixed cadaveric brains.
    • Review of clinical experiences from 40 surgically treated cases of pineal and midbrain lesions.
    • Intraoperative observations focusing on surgical approaches and anatomical variations.

    Main Results:

    • Detailed description of key surgical approaches to the pineal and midbrain regions.
    • Identification of specific anatomical landmarks and critical structures, including the great vein of Galen and its tributaries.
    • Documentation of common surgical pitfalls and strategies to mitigate them.

    Conclusions:

    • Surgical access to pineal and midbrain lesions requires a thorough understanding of complex neuroanatomy.
    • The great vein of Galen and its tributaries represent significant challenges in microsurgical procedures in this area.
    • Careful preoperative planning and meticulous surgical technique are essential for successful outcomes.
