[Effect of contrast media on glycoside-induced mesenteric ischemia].

Experiments in 12 dogs have shown that intra-arterial injection of hyperosmolar contrast into the superior mesenteric artery normally produces a 52% increase in blood flow lasting more than two minutes. Following digitalis-induced mesenteric ischaemia, vaso-dilatation is equally marked, but lasts two and a half times as long. In view of the prolonged vaso-dilator effect of hyperosmolar contrast, arterial spasm could be missed during angiography.
