[A case of duodenal intramural hematoma treated by percutaneous external drainage].

Complicating intramural hematoma is an interesting, relatively unusual condition. Various etiologic factors have been described, with the most common being blunt trauma, anticoagulant therapy, Henoch-Sch nlein purpura and blood dyscrasias. Most intramural hematomas resolve spontaneously with conservative treatment, and the prognosis is good. However, if the abdominal pain or obstruction does not resolve with medical management over seven to ten days, complications such as infarction or peritonitis may occur, and surgical intervention might be required. We report a case of intramural hematoma of duodenum treated with percutaneous drainage and embolization of bleeding focus which was complicated with acute pancreatitis after anticoagulation treatment in a patient with recurrent history of deep vein thrombosis. In addition, we reviewed reports of intramural hematoma of the duodenum and treatment strategies.
