Coagulation disorders are life-threatening, because coagulation disorders are due to various reasons that cause the human body's coagulation function to be impaired. After coagulation dysfunction, the human body will appear a series of bleeding symptoms. If a severe intracranial hemorrhage occurs, it is quite life-threatening. Because coagulation dysfunction can be caused by a variety of diseases, clinically more common vitamin K deficiency, disseminated intravascular coagulation, severe liver disease, hemophilia a, hemophilia b, von Willebrand disease, etc. Coagulation disorders can occur in these diseases.

If it is a patient with severe hemophilia A, he has an obvious tendency to bleed, and it is easy to induce bleeding after a mild trauma. If a patient with severe hemophilia A encounters trauma, it is easy to induce severe cerebral hemorrhage, which endangers the patient's life. In addition, severe disseminated intravascular coagulation is also prone to severe bleeding due to the consumption of various coagulation factors and coagulation dysfunction, leading to early death of patients.
