Subgaleal shunting: a 20-year experience

Area of Science:

• Neurosurgery
• Neurology
• Medical Devices

Background:

• Elevated intracranial pressure (ICP) is a critical concern in various neurological conditions.
• Traditional methods for ICP management carry potential risks and complications.

Purpose of the Study:

• To evaluate the efficacy of diverting intracranial fluid into the subgaleal space for temporary absorption.
• To assess subgaleal shunting as a treatment for hypertensive hydrocephalus, acute head trauma, and chronic subdural hematoma.

Main Methods:

• Retrospective analysis of 81 patients treated over 20 years.
• Description of a simple surgical technique for subgaleal fluid diversion.
• Direct ICP monitoring in 22 cases of cerebral contusion and edema.

Main Results:

• Subgaleal shunting demonstrated effective short-term management of hydrocephalus and elevated ICP.
• The technique was applied to diverse conditions including hypertensive hydrocephalus, acute head trauma, and subdural hematomas.
• Successful temporary absorption of diverted fluid by scalp membranes was observed.

Conclusions:

• Closed subgaleal drainage offers a safe alternative to open ventriculostomy or subdural space drainage.
• This method effectively manages cerebrospinal fluid (CSF) and reduces ICP, avoiding associated complications.
