The aim of the study was to investigate dysfunction and mortality after TIPS and to identify factors associated with these events.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>A retrospective analysis of 834 patients undergoing TIPS implantation in a single center from 1993\u20132018 was performed. Cumulative incidence curves were estimated, and frailty models were used to assess associations between potentially influential variables and time to dysfunction or death.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>1-, 2-, and 5-year mortality rates were 20.9% (confidence interval (CI) 17.7\u201324.1), 22.5% (CI 19.1\u201325.8), and 25.0% (CI: 21.1\u201328.8), 1-year, 2-year, and 5-year dysfunction rates were 28.4% (CI 24.6\u201332.3), 38.9% (CI 34.5\u201343.3), and 52.4% (CI 47.2\u201357.6). The use of covered stents is a protective factor regarding TIPS dysfunction (hazard ratio (HR) 0.47, CI 0.33\u20130.68) but does not play a major role in survival (HR 0.95, CI 0.58\u20131.56). Risk factors for mortality are rather TIPS in an emergency setting (HR 2.78, CI 1.19\u20136.50), a previous TIPS dysfunction (HR 2.43, CI 1.28\u20134.62), and an increased Freiburg score (HR 1.45, CI 0.93\u20132.28).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>The use of covered stents is an important protective factor regarding TIPS dysfunction. Whereas previous TIPS dysfunction, emergency TIPS implantation, and an elevated Freiburg score are associated with increased mortality.
