High thoracic/cervical epidural blood patch for spontaneous cerebrospinal fluid leak: a new challenge for anesthesiologists.

Spontaneous cerebral spinal fluid leakage is increasingly recognized as a cause of headache due to low intracranial pressure. The site of leakage can be identified with radionuclide cisternography, and anesthesiologists are increasingly requested to provide epidural blood patch for their management. This series of case reports demonstrates some of the issues relating to the management of this condition.
