Lumbar myelography with amipaque

Abstract

In lumbar myelography, early side effects occur in about half the patients examined with modern water-soluble contrast media. At myelography with Amipaque (metrizamide) these reactions are usually minor, and serious adverse reactions are rare. In our own series of 650 consecutive lumbar myelographies with Amipaque there were no serious adverse effects. Minor adverse reactions occurred in 56% of the patients. Transient electroencephalogram (eeg) changes were seen in 14% of the patients, with only 5 patients showing paroxysmal spike activity. Adhesive arachnoiditis following lumbar myelography occurs significantly less often with Amipaque than with any other contrast medium. The properties of Amipaque provide excellent possibilities for detailed studies of all parts of the spinal subarachnoid space, and the medium constitutes a new and interesting aid for these investigations.
