This review covers key anticoagulants like tissue factor pathway inhibitor, antithrombin, protein C, and protein S. It details their roles in balancing blood coagulation for veterinary medicine.
Area of Science:
- Veterinary Medicine
- Hematology
- Biochemistry
Background:
- Blood coagulation is a complex process regulated by procoagulant and anticoagulant factors.
- Maintaining a balance between these factors is crucial for hemostasis.
- Dysregulation can lead to bleeding or thrombotic disorders.
Purpose of the Study:
- To review endogenous anticoagulants involved in blood coagulation.
- To discuss tissue factor pathway inhibitor, antithrombin, protein C, and protein S.
- To provide current knowledge on these anticoagulants in veterinary medicine.
Main Methods:
- Literature review of scientific publications.
- Analysis of the origin, structure, and mechanism of action of key anticoagulants.
- Synthesis of information regarding the effects of deficiencies and clinical relevance in animals.
Main Results:
- Detailed description of four major endogenous anticoagulants.
- Explanation of their roles in preventing excessive coagulation.
- Overview of the clinical significance of deficiencies in veterinary patients.
Conclusions:
- Endogenous anticoagulants are essential for maintaining hemostatic balance.
- Understanding these proteins is vital for diagnosing and managing coagulation disorders in veterinary medicine.
- Further research is needed to fully elucidate their roles and therapeutic potential in animals.

Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which forms a...
