In the hypercoagulable phase of disseminated intravascular coagulation, it is most commonly a hyaline thrombus, which exists mainly in the small vessels of the microcirculation, often visible only under the microscope, and its main component is eosinophilic homogeneous fibrin, so it is also called microthrombosis or fibrin thrombosis. However, in clinical treatment, the thrombus will not be overemphasized and what type of thrombus it is, but its strategy is mainly to intervene with some low molecular heparin during the hypercoagulable and embolic phase, and then after the hypercoagulable phase, when it enters the fibrinolytic active phase or bleeding phase, it may transition to the strategy of giving him coagulation factors or coagulation substances as the main supplement, so the focus is on which period the patient is in clinical state to focus on where the main manifestations of his coagulation dysfunction are.
