[The physiopathology, clinical picture and therapy of chronic intestinal ischemia].

Between January 1982 and April 1993, 8 patients suffering from a typical clinical picture of chronic intestinal ischemia, have been observed. All these patients were symptomatic and 7 cases presented stenosing or occlusive lesions of at least 2 of the 3 splanchnic trunks. 5 of these 7 patients underwent a corrective surgical procedure. 2 patients underwent percutaneous transluminal angioplasty. One patient affected by stenosis of the coeliac trunk due to external compression caused by the median arcuate ligament of the diaphragm was not operated because the symptomatology was atypical and the other 2 splanchnic trunks were perfectly patent. Three patients died following the therapeutic procedure: a woman in whom an aorto-mesenteric bypass graft was inserted, underwent, 4 months after, an intestinal infarction due to thrombosis of the graft; another woman, whose coeliac trunk and superior mesenteric artery were thrombosed and whose inferior mesenteric artery was reimplanted on the common iliac artery, died for acute hepatic failure, after 12 months of total parenteral nourishment; a third patient, successfully submitted to PTA of the superior mesenteric artery, died after 4 months due to the occurrence of acute renal insufficiency.
