An autologous blood patch for Cluster Headache involves injecting the patient's own venous blood into the epidural space to stimulate localized inflammatory healing and neurogenic repair. The procedure is believed to promote sealing of potential dural defects, reduce neurogenic inflammation, and modulate pain signaling pathways in the trigeminal and autonomic nervous systems. By creating a localized biological patch and inflammatory response, the intervention can potentially interrupt the pathological mechanisms underlying severe cluster headache episodes.
