[Nonocclusive mesenteric vascular disease following atrio-ventricular block and pacemaker treatment. Gangrene of small and large bowel with occlusion of inferieor mesenteric artery (author's transl)].
A case of nonocclusive mesenteric vascular disease consequential to a low cardiac output syndrome in a patient with a temporary pacemaker is reported. Preexisting occlusion of the inferior mesenteric artery resulted in a total gangrene of small and large bowel. Experimental findings suggest that this occlusion could have resulted in a compensatory increase of blood flow in the superior mesenteric artery. The possibility is discussed that the preexisting necessary increase of superior mesenteric blood flow could be followed by equally increased sensitivity of regional organic systems in non-occlusive mesenteric vascular disease.
