Objective: Safety and effectiveness of the administration of an extensive blood patch in the awake patient by two surgically placed epidural catheters: case series of 7 patients.

Methods: We analyzed 7 consecutive patients in our department treated with this method in the time from 2005 to 2008. All patients where referred with typical symptoms of orthostatic headache, combined with neck pain or not, nausea, blurred vision and distorted hearing. One patient had a history of minor axial trauma.

MRI imaging demonstrated typicall dural gadolinium enhancement, showing subdural effusions in three patients, a spinal effusion in one patient.

Routinely performed myelography and post-myelo-CT revealed dural tears in two patients. Therapy consisted in thoracolumbar monosegmental hemilaminectomy and epidural silicone catheter placement under general anaesthesia. In the awake patient, an extensive blood patch of a minimum of 25 ml each was administered with subsequent removal of catheters.

Results: We report on a complete and immediate resolution of clinical symptoms, dural gadolinium enhancement and regression of subdural effusions in all patients.

Conclusions: In our opinion, the administration of an extensive blood patch by two surgically placed epidural catheters is a simple, well tolerated and highly effective treatment of intracranial hypotension, even in patients with a delayed course in the presence of subdural effusions.
