Glossary Entry: Optic Nerve Sheath Decompression Catheter


Definition: The optic nerve sheath decompression catheter is a medical device used to alleviate pressure on the optic nerve by draining cerebrospinal fluid, particularly in cases of increased intracranial pressure or conditions such as idiopathic intracranial hypertension.

Detailed Description

Types and Variations

Variations: Different models of the optic nerve sheath decompression catheter may vary in size and design, with some specifically tailored for use in pediatric or adult patients.


Common Uses: This device is commonly used in cases of idiopathic intracranial hypertension, traumatic brain injury, or other conditions where elevated intracranial pressure affects the optic nerve function.

Insertion and Placement

Procedure: The insertion of the optic nerve sheath decompression catheter requires specific techniques to ensure accurate placement and function. The Seldinger technique may be used to guide the catheter into the subarachnoid space.

Clinical Considerations

Potential Complications

Risks: Potential complications associated with the use of the optic nerve sheath decompression catheter may include infection, hemorrhage, or damage to surrounding structures.

Care and Maintenance

Maintenance Requirements: Regular monitoring and appropriate care of the catheter are essential to prevent complications and ensure its optimal function.
