Abstract

<p>A spontaneous, intramural, small-bowel hematoma requiring a surgery is a rare complication of anticoagulant therapy. We present a case of an 82-year-old man who developed abdominal pain in the setting of abnormal coagulation function related to warfarin therapy used as chronic prophylaxis against recurrent pulmonary embolism. Computed tomography (CT) showed wall thickening and luminal narrowing of the jejunum. Dilation of the small bowel proximal to the thickening was also present, indicative of small bowel obstruction. Initially, the patient was treated conservatively, but he later required laparotomy due to worsening of his general condition. A 50cm jejunal segment was resected in order to relieve the intestinal obstruction and to arrest the bleeding. For intramural, small-bowel hematoma, conservative medical management should be the first treatment of choice, but surgical intervention may be indicated if conservative treatment is not successful.</p>
