Patients may present with either a bleeding or thrombotic event in which condition?

• A. Dysfibrinogenemia
• B. Hypofibrinogenemia
• C. Afibrinogenemia
• D. Hyperfibrinogenemia

Answer: (A)

Dysfibrinogenemia is a qualitative disorder of fibrinogen—there is a normal or near-normal amount of fibrinogen, but the molecule is functionally abnormal. Because the fibrin formed during clotting is defective, the resulting clots can behave unpredictably: some are prone to breaking down too easily, leading to bleeding, while others may form in a way that resists breakdown or becomes abnormally concentrated, increasing the risk of thrombosis. This dual potential explains why patients can present with either bleeding or thrombotic events. In contrast, conditions with reduced fibrinogen (hypofibrinogenemia or afibrinogenemia) more consistently cause bleeding because there’s simply not enough functional fibrinogen to form stable clots, and hyperfibrinogenemia raises clot risk due to high fibrinogen levels but is less typically associated with bleeding.
