Excretion of aqueous myelographic contrast media in animals undergoing a repeat myelogram.
The rate of elimination of contrast media may be a factor in side effects and complications of aqueous myelography. The authors studied the effect of a previous myelogram and arachnoiditis on the elimination of aqueous contrast media from the subarachnoid space. Serum and cisternal CSF iodine concentrations were measured after experimental myelography in subhuman primates. The transfer of the aqueous contrast media from CSF to serum was slowed and the circulation with the cerebrospinal fluid into the intracranial cisterns was increased by a previous myelogram or arachnoiditis.
