title: Spinal opiate administration: a case of catheter misplacement.
abstract: Continuous spinal opiate administration via permanently implantable drug delivery devices has been proven to provide profound analgesia for chronic pain conditions. We present a case in which the catheter of an implantable subarachnoid device was misplaced into the subdural/extra-arachnoid space despite the free flow of cerebrospinal fluid. This was verified by x-ray dye studies. It is postulated that this misplacement of the catheter likely occurred as a result of recent lumbar punctures the patient had undergone. Extravasation of cerebrospinal fluid created a false space and contributed to the misplacement and ultimate failure of the device to provide analgesia.
