자발성 두개내 저압과 경막외 혈액 봉합술

Abstract

Spontaneous intracranial hypotension (SIH), a syndrome of low CSF pressure, occurs without preceeding events such as lumbar puncture, back trauma, an operative procedure, or medical illness. Postural headache, the most characteristic symptom, usually resolves spontaneously or with bed rest, hydration, and medication. Autologous epidural blood patch is an effective management of headache in SIH patients, and here we describe a one case successfully treated 5 times with an epidural blood patch. The patient had a cardinal feature of a postural headache, low CSF pressure, and showed CSF leakages on RI cisternography. The first three epidural blood patches improved the patient's headache markedly, but the headache recurred in one month. On her second RI cisternography, we found other CSF leakage sites. After a fifth epidural blood patch the patient became asymptomatic and remained so throughout 4 months of follow up. Epidural blood patches are considered the treatment of choice in SIH patients.
