The role of the Liliequist membrane in the third ventriculostomy.

Endoscopic third ventriculostomy (ETV) is a hydrocephalus treatment procedure that involves opening the Liliequist membrane (LM). However, LM anatomy has not been well-studied neuroendoscopically, because approach angles differ between descriptive and microsurgical anatomical explorations. Discrepancies in ETV efficacy, especially among children age 2 and younger, may be due to incomplete LM opening.

The conformation of the brain plays an important role in the distribution of diffuse axonal injury in fatal road traffic accident.

Objective: A study was made of the brain lesions in 120 random victims of fatal road traffic accidents to determine the frequency and topographic distribution of diffuse axonal damage (DAI) in relation to the midline brain structures.

Method: The identification of axons was carried out with a mouse antibody anti-neurofilament proteins 70-, 160-, and 210-kD.

Results: DAI was identified in 96 (80%) brains and classified as Grade 1 in 21.
