Epidural Blood Patch
Michael Jubinville, MPH
An epidural blood patch uses a small amount of blood to create a seal. It's done after a lumbar puncture (LP) to restore normal pressure in the spinal fluid.

Description of the Procedure TOP
Two IVs will be inserted in your arms for medicines, fluids, and to draw blood.
You will lie face down on the table. Your back will be washed and sanitized. An x-ray may be used to help guide a small needle to the area where spinal fluid is leaking. Contrast material will be injected and more x-rays will be taken. A small amount of blood will be drawn and injected into the correct area of the spine. This should clot, or seal, the leakage.
