The rvaj<;.'ity of these patients have poor splanchnic peiiusion without occlusion of their major vessel.-, non- occlusive mesenteric ischemia, as oppo.ed to organic occlusion of the superior mesen!cric artery o: vein. Thc early clinical ct."sgnosis of mesenteric ischemia is difficult to r.ak,. Ince the patient manifests nondescript abdomin-l pain and few abdominal signs. Laboratory studi:s as well as X-ray evaluation are usually nonco:itri- butory. Differentiation between occlus!c and nonocclusive ischemia requires art.-rio raohy.
