[Theory and Practice of Endoscopic Third Ventriculostomy]

Area of Science:

• Neurosurgery
• Neurology
• Medical Devices

Background:

• Hydrocephalus requires surgical intervention to manage cerebrospinal fluid (CSF) pressure.
• Endoscopic third ventriculostomy (ETV) is a standard procedure to alleviate pressure by creating a CSF diversion.
• ETV aims to reduce intracranial pressure and improve brain compliance.

Purpose of the Study:

• To detail the procedure of Endoscopic third ventriculostomy (ETV) for hydrocephalus.
• To highlight critical anatomical landmarks and potential complications during ETV.
• To emphasize post-operative care and monitoring following ETV.

Main Methods:

• ETV involves creating an opening in the floor of the third ventricle.
• Careful navigation is required to avoid injury to the foramen of Monro, hypothalamus, pituitary stalk, and cisternal vessels.
• Management of intraventricular pressure and bleeding is crucial during the procedure.

Main Results:

• Successful ETV provides an alternative route for CSF flow, buffering pulsatile pressure.
• A significant risk of ETV is arterial bleeding, particularly from the basilar artery.
• Potential closure of the ETV stoma due to gliosis or scarring necessitates follow-up.

Conclusions:

• ETV is an effective treatment for hydrocephalus, but requires meticulous surgical technique.
• Awareness and prevention of complications, such as hemorrhage, are paramount.
• Long-term monitoring with physical examinations and MRI is essential to ensure the patency of the ETV.
