Ohtonari T, et al. - In order to ascertain the effects of large-volume epidural blood patch (EBP) in cerebrospinal fluid (CSF) leak patients, researchers reported the outcomes from 15 CSF leak cases that underwent large-volume EBPs using an intravenous catheter from single lumbar entry point, together with outcomes from 4 patients who underwent direct surgical closure or drip-and-rest therapy at the same period. They identified that with the administration of large-volume EBP through an intravenous catheter, a perfect control of spinal CSF leaks was demonstrated.
