title: Mesenteric thrombosis following splenectomy.
abstract: Three cases of postsplenectomy mesenteric thrombosis, two associated with thrombocytosis, are presented. Experience has shown that persistent thrombocytosis, accompanied by abnormal platelet function, is not a benign condition and may be associated with thrombosis. When encountered, postsplenectomy thrombocytosis of greater than 800,000 per mm-3 must be evaluated by platelet function studies and anticoagulation begun. Post-prandial cramping abdominal pain may be an early symptom of thrombosis, demanding immediate anticoagulation. Low-dose heparin, ASA, and dipyridamole are three of the more commonly used treatment modalities. Small bowel resection is indicated if thrombosis occurs.
