Abstract A kaleidoscope of coagulation disorders have been reported in patients with thyroid dysfunctions. Globally, these disorders involve both primary and secondary hemostasis and range from subclinical laboratory abnormalities to, more rarely, life-threatening hemorrhages or thrombotic events. While overt hypothyroidism appears to be associated with a bleeding tendency, hyperthyroidism emerged to have an increased risk of thrombotic events. In particular, a number of case reports have documented acute venous thrombosis complications in patients with overt hyperthyroidism, especially at cerebral sites. Nevertheless, further observational and intervention studies might be needed to provide a more definitive information on the clinical relevance of this association, along with the potential implication for prevention and treatment of coagulation-fibrinolytic abnormalities in patients with thyroid dysfunction.
