Abstract

Until the beginning of the 90ies, it was believed that patients with liver cirrhosis were auto-anticoagulated and thus protected from thromboembolic events. However, new discoveries have broken the longstanding paradigm. In deranged hepatic function there is a reduced synthesis of procoagulants and endogenous anticoagulants, however, extrahepatally synthesized hemostatic and fibrinolytic factors are disproportionately affected. In stable disease hemostatic system is ”rebalanced’’ but fragile, therefore, even a minimal stress can promote bleeding or thrombosis. Also, there are many concomitant factors, such as hemodynamic changes, other organ affection, namely kidney, and predisposition to infection, that shift the balance towards either bleeding or thrombosis. Conventional laboratory tests are not sufficient for evaluation of the bleeding risk, prothrombotic risk factors are not clearly identified, and safety profile of antithrombotic drugs is not precisely evaluated since cirrhotic patients are mainly excluded from big clinical trials. For all that is said, the diagnostic and therapeutic approach in this context is complex and requires teamwork of a hepatologist, hematologist and in a phase of operative treatment, the anesthes...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
