Abstract
Non-occlusive mesenteric ischemia (NOMI) is an acute mesenteric circulatory disorder that does not involve the organic occlusion of blood vessels and is associated with extremely high mortality. In 1974, Siegelman addressed angiographic criteria for the diagnosis of mesenteric vasospasm, which was gold standard for NOMI diagnosis. But the bowel ischemia diagnosis of objective examinations was improved for recent progress of multidetector-row computed tomography and ultrasonography. Therefore the new standard establishment of diagnosis of NOMI is expected. NOMI had no particular symptom, so this diagnosis was so late at severe conditions. If the patient was diagnosed for NOMI, the indication of intravenous vasodilative medication was performed for no symptom of peritonitis, and for peritonitis, surgery should be performed. Therefore construction of standardization and treatment new algorithm of the diagnosis of NOMI is desired.
