A patient with sigmoid colon adenocarcinoma and hypercoagulable state developed acute visceral ischemia secondary to thrombus involving the suprarenal aorta, celiac axis and superior mesenteric artery. A large, laminated fibrin thrombus was removed via supraceliac aortotomy. Attempts to clear thrombus from branches of the celiac axis and superior mesenteric artery by open and catheter-based techniques were of limited success. Extensive visceral infarction ensued and the patient died.
