Hypoprothrombinemia

Hypoprothrombinemia is a hematologic coagulation disorder characterized by abnormally low circulating levels or activity of prothrombin (factor II), a vitamin K–dependent clotting factor essential for thrombin generation and fibrin clot formation Clinically, affected individuals demonstrate prolonged prothrombin time and activated partial thromboplastin time, predisposing them to an increased bleeding tendency that ranges from mild mucocutaneous ecchymoses and epistaxis to severe postoperative h...
