[Intestinal infarction. Retrospective clinical study].

Acute mesenteric ischaemia is the result of inadequate blood flow to all or part of the small intestine and the right half of the colon. Irrespective of the cause of the ischaemic insult, the end results are similar, namely, a spectrum of bowel injury ranging from completely reversible alterations of bowel function to transmural haemorrhagic necrosis of the intestinal wall. Depending on the degree of ischaemia and the length of bowel involved, a wide variety of clinical presentations are observed. Mesenteric infarction is a pathology which is encountered fairly often in elderly patients where the concomitance of other diseases make its prognosis more severe, especially since the diagnosis is usually late. The pessimism expressed more than 70 years ago concerning this disease is still shared by many physicians today. The authors report on their experience with 37 cases of mesenteric infarction. The median age of the patients was 77 years (range: 66-91). The mortality rate was 67.5% (25 deaths) which is in line with the results in the literature. The median hospital stay was 17 days (range: 10-71). The authors emphasise the difficulty of diagnosing and treating this entity, also in view of the fact that, in most centres, it is impossible to perform emergency selective angiography of the superior mesenteric artery. The need for an early specific diagnosis is stressed, because the therapeutic options may vary widely in relation to the different causes of acute intestinal ischaemia.
