Dry necrosis of the ear shell

Auricular dry necrosis is one of the clinical manifestations of diffuse intravascular coagulation. Diffuse intravascular coagulation (abbreviated as DIC) is not a separate disease, but a complex pathological process and clinical syndrome caused by multiple causes. Embolism in clinical manifestations, the general symptoms of embolism are local congestion, hemorrhage, or extremity cyanosis. Long-term embolization of the non-tip area can lead to rhinitis and dry necrosis of the ear shell. It is characterized by extensive platelet aggregation and fibrin deposition in the microcirculation, leading to diffuse microthrombosis, secondary clotting factor and large consumption of platelets, and hyperfibrinolysis, which causes microcirculation disorders, bleeding, hemolysis And other serious clinical manifestations. The condition of acute diffuse intravascular coagulation progresses rapidly, and if not treated in time, it is often life-threatening.
