SPINAL CORD TOLERANCE TO ROENTGEN CONTRAST MEDIA PARTICULARLY DURING AORTOGRAPHY WITH TEMPORARY OCCLUSION OF AORTA - AN EXPERIMENT INVESTIGATION IN DOGS

Aortography with occlusion of the aorta in dogs was found to raise the risk of damage to the spinal cord considerably, as compared to aortography during free circulation. Two injections above the occlusion, each of 1 rnl/kg bodyweight of one of the least toxic of the contrast media, caused severe irreversible damage to the spinal cord, as was also the case when the hypertonic saline was used. It is pointed out that also other methods of changing the circulation during angiography may be connected with risks of injury to the spinal cord. © 1969, The Foundation Acta Radiologica.
