title: [Two cases of small bowel ischemia due to unusual cause].
abstract: The authors report 2 cases of small bowel ischemia due to unusual cause. In both cases, vasculopathy was the cause of ischemia, but with a different etiology. In the first case, a mesenteric inflammatory veno-occlusive disease, with striking features of extensive phlebitis and venulitis affecting the veins of the small intestine and mesentery, without arterial involvement of this district was observed and histological examination showed inflammatory lymphocytic infiltrates and myointimal hyperplasia of the veins. The second case affected by intestinal ischemia from secondary and multiple cholesterol embolism, the histological examination showed inflammatory infiltrates with (lymphocytes and granulocytes) in the vessels of submucosal mesenteric area, by loose intimal fibrosis incorporating cholesterol clefts. Both patients required surgical exploration with resection of ischemic bowel. In the second case laparoscopy was the initial approach which allowed to identify the extension of ischemia with special regard to the perforation. The ultimate diagnosis is possible only with histological examination. Clinically, patients show the general signs of intestinal ischemia with pain, vomiting and bloody diarrhea. Prognosis depends on the extension of the lesions and the early surgical treatment.
