<unk>  (abbreviated ATIII deficiency) is a deficiency of<unk> <unk> . This deficiency may be inherited or acquired. It is a rare hereditary disorder that generally comes to light when a patient suffers recurrent venous thrombosis and pulmonary embolism, and repetitive intrauterine fetal death (IUFD). Hereditary<unk>  deficiency results in a state of increased coagulation which may lead to venous thrombosis. Inheritance is usually autosomal dominant, though a few recessive cases have been noted. The disorder was first described by Egeberg in 1965. The causes of acquired<unk>  deficiency are easier to find than the hereditary deficiency. The prevalence of<unk>  deficiency is estimated at ~0.02 to 0.2% of the general population, and 1-5% of patients with venous thromboembolism. There is an elevated risk of thrombosis, whereby 50% patients with AT deficiency were found to have venous thromboembolism by age 50.
