Purpose To assess the impact of transjugular intrahepatic portosystemic shunt (TIPS) creation on Model for End-stage Liver Disease (MELD) score temporal progression in patients with liver cirrhosis. Materials and methods In this single-institution retrospective study, 256 consecutive patients who underwent TIPS creation between 1999 and 2013 were identified for potential investigation. Inclusion criteria for analysis consisted of at least 6 months of post-TIPS clinical follow-up with available lab values at 1, 3, 6, and, if available, 12 months post-TIPS for MELD score calculation. Patients who were lost to follow-up or expired within 6 months, lacked sufficient lab follow-up, or underwent liver transplantation within 6 months of TIPS were excluded from the study cohort. Within-patient variance in MELD score was assessed using repeated-measures analysis of variance. Results Sixty-six patients met criteria for study inclusion. TIPS were created for variceal hemorrhage (n = 26) or ascites, hydrothorax, or portal vein thrombosis (n = 40). Hemodynamic success rate was 97% (64/66) and median portosystemic pressure gradient reduction was 13 mm Hg. Median baseline MELD score was 14 (range 7-26). Low MELD scores (≤10, n = 16) increased in sequential scores over 1-year follow-up (median increase +3.5), intermediate MELD scores (11-18, n = 34) showed general stability in successive scores over 1-year follow-up (median increase +1), and high MELD scores (≥19, n = 16) decreased in serial scores over 1-year follow-up (median decrease -4); these trends are compatible with published MELD progression tendencies in cirrhotic patients without TIPS. However, the MELD score changes were not statistically significant (P =.172) on within-subject comparison. Conclusions Among patients with liver cirrhosis who recover from the procedure, TIPS creation does not alter the natural MELD score evolution during intermediate term follow-up, and as such does not significantly alter liver transplant candidacy.
