Secondary hemostasis refers to the deposition of insoluble fibrin, which is generated by the proteolytic coagulation cascade. This insoluble fibrin forms a mesh that is incorporated into and around the platelet plug. This mesh serves to strengthen and stabilize the blood clot.

Secondary Hemostasis (Coagulation Cascade): This is the reinforcement phase, taking over from platelets within a few minutes. A complex cascade of proteins called coagulation factors kicks in, creating a fibrin mesh that strengthens and stabilizes the platelet plug into a permanent clot.

Coagulation is the process of formation of a blood clot. It is secondary hemostasis that occurs after vascular damage has occurred and platelets have been activated. Its purpose is to form the fibrin mesh necessary to stabilize the platelet plug to stop bleeding.

2024年11月27日 · Hemostasis is your body’s way of stopping bleeding and making a repair after an injury. Seconds after an injury, your body starts the process of forming a plug or clot. Making a clot conserves blood and prevents infections.

2020年8月11日 · Secondary hemostasis – formation of the final, stable fibrin clot, which is triggered by the complex series of events known as the proteolytic coagulation cascade. Primary and secondary hemostasis occurs simultaneously and their complex mechanisms are interlaced.

Definition: Secondary hemostasis is defined as the formation of insoluble, cross-linked fibrin by activated coagulation factors, specifically thrombin. Fibrin stabilizes the primary platelet plug, particularly in larger blood vessels where the platelet plug is insufficient alone to stop hemorrhage.

2025年1月6日 · The coagulation cascade, or secondary hemostasis, is a series of steps in response to bleeding caused by tissue injury, where each step activates the next and ultimately produces a blood clot. The term hemostasis is derived from “hem-”, which means “blood”, and “-stasis”, which means “to stop.”

2023年9月4日 · Secondary hemostasis involves the clotting factors acting in a cascade to ultimately stabilize the weak platelet plug. This is accomplished by completing three tasks: (1) triggering activation of clotting factors, (2) conversion of prothrombin to thrombin, and (3) conversion of fibrinogen to fibrin.

2023年8月28日 · Secondary hemostasis includes the two main coagulation pathways, intrinsic and extrinsic, that meet up at a point to form the common pathway. The common pathway ultimately activates fibrinogen into fibrin.

Secondary haemostasis describes the process whereby exposure of tissue factor to the bloodstream leads to a series of enzymatic reactions that result in a sufficient burst of thrombin production to convert soluble fibrinogen into a stable network.
