title: [Epidural blood patch for the treatment of intracranial hypotension due to cerebrospinal fluid leakage after thoracic spine surgery].
abstract: We report a case of a 44-year-old woman successfully treated by an epidural blood patch for intracranial hypotension due to cerebrospinal fluid (CSF) leakage into the thoracic cavity after thoracic spine surgery. The patient was admitted to our hospital with the complaint of postural headaches. She had received anterior thoracic instrumentation for thoracic disc herniation four months earlier. Lumbar puncture demonstrated low CSF pressure, and Gd-enhanced MR images displayed diffuse dural enhancement. Accordingly, she was diagnosed as having intracranial hypotension. 111In-DTPA cisternography revealed a CSF leakage into the left thoracic cavity, possibly caused by dural laceration during thoracic spine surgery. To avoid the risk of direct surgery, we performed epidural blood patch; 3 ml of autologous blood was injected into the epidural cavity. Postoperatively postural headaches immediately disappeared. MRI taken one year later revealed disappearance of diffuse dural enhancement, and 111In-DTPA cisternography revealed no CSF fluid leaks. Epidural blood patch seems to be a choice of treatment for CSF leak after spinal surgery.
