What is a blood patch?

A blood patch is a procedure in which a small amount of the patient's own blood is injected into the space around the spinal cord to seal a leak of cerebrospinal fluid. This procedure is typically done to treat a spinal headache or low pressure headache that occurs after a spinal tap or other procedure that involves puncturing the spinal cord.

The blood patch works by creating a clot at the site of the leak, which helps to stop the flow of cerebrospinal fluid and alleviate the headache. The procedure is usually performed under local anesthesia and is considered to be a safe and effective treatment for spinal headaches.

Possible risks and complications associated with a blood patch include infection, allergic reaction, and nerve damage. However, these risks are generally rare and most patients experience significant relief from their symptoms after the procedure.

It is important to follow your healthcare provider's instructions before and after a blood patch procedure to ensure the best possible outcome. If you experience any persistent or worsening symptoms after the procedure, it is important to contact your healthcare provider immediately for further evaluation and treatment.
