Computerized tomographic imaging of patient's abdomen at presentation. A computerized tomogram of the patient's abdomen performed soon after admission demonstrating (a) hypoperfusion of the right side of his liver (demarcation line indicated by blue arrow); (b) cavernous replacement of the portal vein (arrowed) consistent with thrombotic occlusion of this vessel and (c) varices around the gallbladder (arrowed). In addition the scan showed (d) a thickened loop of ileum (arrowed) suggestive of incipient venous gangrene secondary to concomitant thrombosis of the superior mesenteric vein.
