title: Myelography in lumboperitoneal shunts.
abstract: Lumboperitoneal shunts have become more prevalent since the introduction of Silastic tubing. One disadvantage of this procedure is the difficulty in obtaining a subsequent myelogram. In the presence of a lumboperitoneal shunt, it may be advisable to modify the usual technique in obtaining a satisfactory myelogram. Use a low lumber puncture for a lumbar study, a C1-2 puncture for the cervical and thoracic regions, and use metrizamide to avoid the potential problem of Pantopaque in the peritoneal cavity.
