BACKGROUND/AIM: Thrombocytopenia is a common complication of chronic liver disease. The theory of portal decompression to improve thrombocytopenia due to hypersplenism has led to the study of transjugular intrahepatic portosystemic shunt (TIPS) as a potential therapy. However, there is a paucity of data and results have been conflicting. The aim of this study was to determine whether platelet counts improved in cirrhotic patients after placement of the new polytetrafluoroethylene (PTFE)-coated TIPS, developed in 2004.
METHODS: This is a retrospective cohort study of 68 patients with chronic liver disease who underwent a TIPS procedure. One-hundred twenty controls who did not undergo a TIPS procedure were matched on average for age, sex, race, model for end-stage liver disease (MELD) score, and etiology of liver disease. Platelet and hemoglobin counts were recorded during the month prior to the TIPS procedure (baseline) and over the following 12-14 months or until transplanted or death.
RESULTS: While platelet counts improved during the first 3 months after TIPS with a mean increase of 11.25 × 103/μL (p = 0.064), they returned to baseline (pre-TIPS) with mean platelets of 91.31 × 103 μL by 12-14 months in comparison with a mild decrease of 10.2 × 103 μL in platelet counts in the control group from 100.4 × 103 μL to 90.2 × 103 (p = 0.119). There was also no significant correlation between platelet counts and etiology of liver disease, age, race, gender, or MELD score. Hemoglobin counts were found to have a small increase of 0.657 g/dL over the 12-14 month course in the TIPS group, which was statistically significant (p = 0.003).
CONCLUSION: There does not appear to be a significant improvement in thrombocytopenia in cirrhotic patients after TIPS placement, despite advances in TIPS stents. However, there may be a mild improvement in anemia after TIPS implantation.
