Abstract:
We present a case of spontaneous intracranial hypotension (SIH) diagnosed from the clinical symptoms and magnetic resonance imaging brain scans. After failure of conservative treatment, and lack of identification of the cerebrospinal fluid leak site, the headache was managed successfully and simply with two applications of an epidural blood patch (EBP). The strategy of our management for the patient was as follows: (1) application of an EBP to the lumbar epidural space initially and manipulating it into the proximity of the possible leak site; (2) a greater volume of autologous blood was injected at the second attempt of EBP; and (3) the patient was required to lie flat for at least 2 hours after the procedure. Better management of SIH is still developing. Traditionally, SIH is initially managed by conservative treatment. However, recent studies have shown that the success rate in arresting SIH after weeks or months of conservative treatment is not quite satisfactory. Hence, the EBP has proven to be more effective in treating SIH patients. Early EBP application may offer immediate relief of clinical symptoms. The role of the EBP in treating SIH patients should have greater emphasis and its application is worth recommendation.
