title: [The Clinical Features of Cerebrospinal Fluid Leaks--Based on Our Experiences].
abstract: Cerebrospinal fluid (CSF) leak, which usually occurs idiopathically or traumatically as a rare situation, is a rare disease that causes orthostatic headache or idiopathic chronic subdural hematoma (CSDH). We report our therapeutic experience of consecutive 20 cases for this disease, and review the current status and problems. Consecutive 20 patients (11 women; age 44.7±12.1 years) between April, 2006 and March, 2014, who were diagnosed by MRI and/or CT myelography (CTM), were evaluated retrospectively about clinical features. The main symptoms were as follows: orthostatic headache only; 10 cases, orthostatic headache with CSDH; 6, and none-orthostatic headache accompanied with CSDH; 4. As a treatment, direct surgeries were performed in 2 cases. Epidural blood patch (EBP) was applied in 14 cases (direct surgery was performed finally in the early one case), and widespread EBP with a single lumbar entry point utilizing an intravenous catheter was performed especially in the latest 9 cases. Another 5 cases were treated simply with the administration of a drip infusion regardless of the drainage for CSDH. Of 10 cases suffering from headache only, the headache disappeared completely or it was relieved in 9 cases. Of 10 cases accompanied with CSDH, recurrence of hematoma was prevented in all cases with a drip infusion after the drainage in one case and EBP after the drainage in another 9 cases. It was certified that we could diagnose CSF leak correctly with MRI and/or CTM and control this disorder almost completely with widespread EBP utilizing an intravenous catheter.
