Postdural puncture headache is a leak of cerebrospinal fluid that lowers intracranial pressure and usually presents as a positional headache. If conservative treatments are not successful, the epidural blood patch is the gold standard of the treatment for dural puncture. The interlaminar approach is the most commonly used technique for an epidural blood patch. This case report describes a patient who was treated with a transforaminal epidural blood patch for postdural puncture headache following an acupuncture procedure on his lower back after two epidural blood patches using an interlaminar approach had failed. The patient underwent an acupuncture therapy for management of chronic low back pain due to postlaminectomy syndrome. After the procedure, the patient had a severe headache and the conservative treatment was not effective. The two interlaminar epidural blood patches at the L2–3 level and at the L3–4 level were failed. We performed transforaminal epidural blood patch at the L3–4 and L4–5 levels on the left side, the site of leakage in the MRI myelogram. His symptoms finally subsided without complication. This case demonstrates that targeted transforaminal epidural blood patch is a therapeutic option for the treatment of postdural puncture headache when epidural blood patch using an interlaminar approach is ineffective.
