Y1 - 2011 N1 - T2 - Williams Manual of Hematology, 8e AB - Risk factors for thromboembolism may be genetic and acquired (Table 89–1).Hereditary thrombophilia is a genetically determined increased risk of thrombosis.Up to 50 percent of patients presenting with a first deep venous thrombosis will have an abnormal laboratory test suggesting a thrombophilic defect, and patients with recurrent thromboses or with a strong family history are even more likely to have laboratory evidence of a thrombophilic state (Table 89–2).Up to 16 percent of patients with thrombophilia have inherited more than one abnormality.These inherited defects also interact frequently with acquired risk factors, such as inactivity, trauma, malignancy, or oral contraceptive use, to lead to clinical thrombosis.
