Lumbosacral meningismus complicating subdural injection of "blood patch": case report

Abstract

The published literature suggests that the technique of epidural "blood patch" injection is both safe and effective for the treatment and prevention of headache after spinal puncture. However, a case is reported in which the complications following a "blood patch" outweighed the disability and discomfort produced by the headache itself. The etiology is believed to have been inadvertent injection of blood into the subarachnoid space.
