SAAVEDRA GONZALEZ, Yesid Alberto; OVADIA CARDONA, Laura Margarita; MUNOZ MAYA, Octavio Germán  e  CORREA ARANGO, Gonzalo. Old and new paradigms for cirrhosis associated coagulation abnormalities. Rev Col Gastroenterol [online]. 2012, vol.27, n.2, pp.104-112. ISSN 0120-9957.

In liver disease one of the liver's functions related to blood coagulation, hemostasis, is disturbed. This manifests as hypercoagulability in some patients and as excessive bleeding in others. Objective: The objective of this study was to review current evidence about blood coagulation disorders in cirrhotic patients. Methods: We conducted a search using the following "MESH" terms: blood coagulation disorders, cirrhosis, hemostasis, hypercoagulability, bleeding and blood coagulation tests. From the results articles whose titles and abstracts best fit with the aim of this review were chosen. Results: From 146 articles obtained, 76 were selected and used to construct this article. Conclusion: Despite the diverse blood coagulation disorders present in cirrhotic patients, the hemostatic system accomplishes a new balance that currently used blood coagulation tests fail to show. This is the why these cannot be considered useful tools for predicting the risk of bleeding or thrombotic complications.
