title: Delayed intestinal stenosis of nonocclusive mesenteric ischemia after autologous blood collection: A case report.
abstract: BACKGROUND
  Nonocclusive mesenteric ischemia (NOMI) has been reported to be associated with high mortality. Early diagnosis of NOMI and prompt restoration of the intestinal blood flow is necessary in order to achieve a favorable outcome.
  
  
  METHODS
  We present the case of a patient who developed NOMI after autologous blood collection and was treated by selective infusion of the superior mesenteric artery with papaverine, intestinal decompression using a long intestinal tube, the administration of antibiotics, and fluid replacement. Although this non-surgical management was successful, 8 weeks after the ischemic event, segmental bowel resection was necessary because of repeated intestinal obstruction caused by bowel stricture.
  
  
  CONCLUSIONS
  Autologous blood collection might be a risk factor of NOMI. In addition, the possibility of delayed intestinal stenosis remains, even if bowel necrosis and surgical resection were avoided with non-surgical management including vasodilator therapy.
  
  
  CONCLUSIONS
  Rapid diagnosis and intervention are essential to minimize intestinal ischemia.
