Coagulation disorders are life-threatening because they are caused by various reasons that lead to a disruption of the body’s blood clotting function, which results in a series of bleeding symptoms. If a serious intracranial hemorrhage occurs, it can be quite life-threatening. Because coagulation disorders can be caused by a variety of diseases, the more common ones clinically are hemophilia a, hemophilia b, vascular hemophilia, vitamin K deficiency, disseminated intravascular coagulation, and severe liver disease bands, all of which can develop coagulation disorders. In the case of severe hemophilia a patients, who themselves have a pronounced tendency to bleed, mild trauma can easily induce bleeding afterwards. If a patient with severe hemophilia a suffers a traumatic injury, a severe cranial hemorrhage can easily be induced, thus endangering the patient’s life. In addition, severe diffuse intravascular coagulation, also due to the depletion of various coagulation factors and coagulation dysfunction, is also prone to severe bleeding, leading to early death of the patient.
