Abstract
IN 1929 Dos Santos and his associates1 described their technique of aortography, in which the abdominal aorta and its branches were made opaque to x-rays by an aqueous solution of sodium iodide introduced by percutaneous aortic puncture via the translumbar route. Subsequently, the opaque medium was introduced through a catheter inserted along a major artery, such as the femoral artery. The results were comparable with the earlier method, and abdominal aortography by either route is now used extensively as a diagnostic procedure to investigate diseases of the aorta, major arteries, and some of the abdominal viscera. The occasional complications which have followed abdominal aortography have sometimes been caused by errors in technique but also by a direct toxic effect of the contrast medium exerted in the distribution of the arteries arising from the abdominal aorta. Such toxic reactions have been described in the kidneys, adrenals, intestines, pancreas, spleen
