Despite gastrointestinal bleeding, anticoagulation therapy with heparin had to be performed to prevent bowel infarction. In this case, local vascular lesions with altered blood flow in combination with hyperfibrinogenemia might have caused superior mesenteric vein thrombosis. © 2003 Lippincott Williams & Wilkins, Inc.
