A 78-year-old man presented with abdominal pain, high International Normalised Ratio and rapidly falling haemoglobin. He had a background of Marfan syndrome and was on warfarin following mechanical aortic valve replacement. Abdominal CT imaging showed haemoperitoneum with a leaking aneurysm of the left gastric artery measuring 10 mm in diameter. The decision whether to reverse his anticoagulation provided a difficult clinical scenario given the risk of thrombosis associated with the mechanical aortic valve. The patient went on to have a successful percutaneous embolisation of the aneurysm using a metallic coil and Onyx. Left gastric artery aneurysms are rare and have a reported mortality of up to 70%. This is the first case of gastric artery aneurysm described in a patient with Marfan syndrome.
