SYMPATHETIC NERVE ENTRAPMENT POINT INJECTION AS AN ADJUVANT TREATMENT FOR INTRACTABLE CLUSTER HEADACHE: A CASE REPORT.

Cluster headache (CH) is characterized by severe unilateral pain ranging from the orbital to the temporal regions with ipsilateral autonomic manifestations. Although most patients respond to drugs or oxygen inhalation, some do not. In this case report, we introduce sympathetic nerve entrapment point injection (SNEPI), a new adjuvant treatment for CH. We introduce two CH patients who did not respond well to pharmacological treatment or 100% oxygen inhalation, but who improved after SNEPI. Patient 1, a 42-year-old man, visited the Emergency Department (ED) with severe periorbital right frontal headache accompanied by ipsilateral rhinorrhea, conjunctival injection, and eyelid edema. The symptoms did not fully respond to drugs or oxygen inhalation, but improved after SNEPI into the tender point of the splenius capitis (SC) muscle; there was no further pain for 1 month thereafter. Patient 2, a 26-year-old woman, presented to the ED complaining of severe headache in the right supraorbital-temporal-occipital region with ipsilateral lacrimation and conjunctival congestion. The patient was taking various drugs for CH, but there was no improvement; the symptoms improved dramatically after SNEPI into the tender points of the SC and paraspinal deep muscles (levels T1-2), and the pain was well managed with reduced drug doses for 3 months. Why Should an Emergency Physician Be Aware of This? CH can cause severe acute pain, and sometimes pharmacological treatment or oxygen inhalation is not effective. SNEPI, which is inexpensive and can be easily performed, may be considered as an adjuvant treatment for intractable CH in the ED. Copyright © 2023 Elsevier Inc. All rights reserved.
