Abstract

An elevated level of factor VIII is a recognised risk factor for thromboembolism. This case report describes a patient with elevated factor VIII levels secondary to hyperthyroidism. She presented with a triad of clinical hyperthyroidism, pulmonary emboli and cerebral venous thrombosis. This case highlights the importance of considering thromboprophylaxis in patients with clinical hyperthyroidism.
