Hemostasis in liver diseases

: Liver plays central role in the synthesis and metabolism of the pro- and anticoagulant enzymes of blood coagulation. Acute or chronic liver failure frequently result in different bleeding phenomena. Thrombocytopenia due to hypersplenism and lack of haemopoietic factors seems to be common, but in spite of thrombocytopenia and more or less platelet malfunction thrombocytopenic bleeding is usually less prominent feature. Bleeding esophageal varices, clotting abnormalities with peritonejugular shunts may pose many difficulties in clinical practice. Transjugular intrahepatic shunt (TIPS) has been a major step forward treating refractory esophageal bleeding or ascites, however to keep the stent patent seems to be still unresolved. Along with the bleeding tendency or symptoms concommittant venous thromboembolic events are may not be considered as rare events in cirrhosis. Special problems are also coupled with ascites, which contains an almost full inventory of coagulation proteins, also with the medical and interventional therapy of Budd-Chiari syndrome, and other veno-occlusive conditions with or without transplantation.
