Trastornos de la coagulación en cirrosis hepática: artículo de revisión

The pathophysiological events of liver cirrhosis drastically alter the processes of primary and secondary hemostasis and fibrinolysis. Previously, it was conceptualized that these alterations exclusively predisposed to hypocoagulation, due to the low hepatic production of procoagulant factors and the characteristic thrombocytopenia. Currently, there is evidence of compensation mechanisms that lead to a hemostatic rebalancing, which is unstable and easily dysregulated in the presence of comorbidities, complications and progression of the disease, leading to prohemorrhagic or prothrombotic phenomena, such as portal vein thrombosis, venous thromboembolism, etc. To effectively determine whether a cirrhotic patient is at risk for bleeding, conventional coagulation tests are not helpful. Treatment will depend on the hypo or hypercoagulable state of the patient. In this manuscript, we review the hemostatic phenomena in cirrhosis, to reveal its characteristics, effective diagnostic methods and treatment
