title: Anticoagulant-induced intramural duodenal haematoma presenting with upper-gastrointestinal haemorrhage.
abstract: Warfarin is an anticoagulant agent known to have a common complication, bleeding. Intramural intestinal haematoma is an uncommon incidence of warfarin-induced haemorrhage. Abdominal pain is its most frequent symptom and presentation with upper-gastrointestinal haemorrhage is rarely seen. Here, we present a 67-year-old male who was admitted to the hospital with active upper-gastrointestinal haemorrhage. In this case, the cause of bleeding has been attributed to duodenal intramural haematoma due to warfarin overuse.
