Thromboembolic episodes are quite rare in beta thalassemia major patients although there is a tendency for thrombosis in haemolytic anaemias. We report a patient with cerebral thromboembolic episode triggered by a minor blood group incompatibility in which the underlying defect of factor V 1299 (His-Arg) was detected three years after his death.
