* Patients ultimately identified with nonocclusive mesenteric ischemia will not benefit from anticoagulation, at which point it can be discontinued.
¶ Imaging signs associated with mesenteric ischemia include focal or segmental bowel wall thickening, intestinal pneumatosis, portal vein gas, portomesenteric thrombosis, mesenteric arterial calcification, and mesenteric artery occlusion.
Δ Medically fit patients.
