Spinal angiography with Iohexol

Summary Iohexol 300 was used for 55 selective spinal angiograms in 50 patients; all were of good quality. There was no significant change in vital signs during the angiographic procedure in any case. Two patients with spinal dural arteriovenous fistula draining into a coronal venous plexus developed transient subjective slight increase in their disability during the immediate post-angiographic period. Eight cases embolised at the time of angiography showed improvement in their neurological deficits within 24 h of the study. The other patients were unaffected by the procedure. Iohexol 300 is a very suitable contrast medium for spinal angiography.
