Intestinal infarction complicating low cardiac output states.
Nonocclusive mesenteric ischemia, leading into intestinal infarction, frequently complicates and causes the fatal outcome in otherwise treatable instances of low cardiac output states. Once intestinal necrosis occurs in these patients, the mortality is almost 100 per cent. A high risk group of patients in whom intestinal infarction occurs because of low cardiac output can be readily identified. A high index of suspicion for the occurrence of intestinal ischemia in these patients should facilitate recognition of the disease during its early stages. The disastrous results experienced by us and others warrant the use of more aggressive methods for the diagnosis and treatment of patients with this condition. A high index of suspicion in a recognizable group of patients observed by selective mesenteric arteriography affords a method for confirmation of the diagnosis of mesenteric vasoconstriction. Once the diagnosis is established, a patient management protocol program should be followed. Sustained infusion of papaverine into the mesenteric artery is useful in reversing mesenteric vasoconstriction. Additionally, the judicious use of celiotomy and intestinal resection, preceded and followed by the sustained infusion of papaverine into the superior mesenteric artery, offers hope for the survival of some of these patients and warrants further use.
