In recent years there has been an important change regarding the thrombotic risk estimation of patients with liver cirrhosis, underestimated in the past in favor of the hemorrhagic risk. The appearance of the hepatocarcinoma in the chronic liver diseases evolution increases the thrombotic risk of the patients. We have created a retrospective, multicentric clinical study, including 215 consecutive patients hospitalized in 3 university sites from Transylvania. We have analyzed the complete blood panel parameters, coagulation tests, the thrombotic risk score and the thrombotic and hemorrhagic events of the patients. Over a third of the patients presented thrombosis. The mean platelet volume and the other platelet parameters do not correlate with thrombotic events. The number of platelets correlates directly with the thrombotic risk score. The results are analyzed in the light of the physiopathologic disturbances induced to these patients.
