    Area of Science:

    • Neurosurgery
    • Surgical Techniques
    • Neuroendoscopy

    Background:

    • Aqueductal stenosis can cause obstructive hydrocephalus, increasing intracranial pressure.
    • Third ventriculostomy is a neurosurgical procedure to create an alternative pathway for cerebrospinal fluid (CSF) flow.
    • Traditional techniques may have limitations in achieving adequate access to the third ventricle floor.

    Purpose of the Study:

    • To present a refined microtechnical approach for performing third ventriculostomy.
    • To describe the combined opening of the lamina terminalis, basal membrane, and Liliequist membrane.
    • To evaluate the utility of this technique in managing aqueductal stenosis.

    Main Methods:

    • A microtechnical surgical approach was employed, emphasizing the use of an operating microscope.

    Related Experiment Videos

  • The procedure involved fenestration of the lamina terminalis and the basal membrane of the third ventricle floor.
  • Crucially, the membrane of Liliequist was opened to enhance surgical visualization and access.

    • Main Results:

    • The described microtechnical third ventriculostomy was successfully performed in five patients with aqueductal stenosis.
    • Opening the membrane of Liliequist provided significant additional surgical access.
    • The technique facilitated the creation of a functional CSF diversion pathway.

    Conclusions:

    • The microtechnical approach to third ventriculostomy, including opening the membrane of Liliequist, is a valuable technique.
    • Enhanced access through the membrane of Liliequist is critical for successful endoscopic third ventriculostomy.
    • This method offers a promising alternative for managing aqueductal stenosis and related hydrocephalus.
