Thyrotoxicosis causing arterial and venous thrombosis.

We present an interesting case of a patient with thyrotoxicosis who developed both arterial and venous thrombosis. Although there have been reports of thrombosis in such patients, there has been no case reporting arterial and venous thrombosis in the same patient. We describe the case and discuss the medical literature. We feel that any patient with unexplained hypercoagulability should be thoroughly evaluated for thyroid dysfunction.
