Background: The impact of transjugular intrahepatic portosystemic shunt (TIPS) on waitlist mortality and liver transplantation (LT) urgency in Budd-Chiari Syndrome (BCS) patients remains unclear. Method: We analyzed BCS patients listed for LT in the UNOS database(2002-2024) to assess TIPS’s impact on waitlist mortality and LT access via competing-risk analysis. We compared trends across two phases:Phase1(2002-2011) and Phase2(2012-2024). Results: Of 815 BCS patients, 263(32.3%) received TIPS at listing. TIPS group had lower MELD-Na scores(20vs22,p<0.01), milder ascites(p=0.01), and fewer Status1 patients(those at risk of imminent death while awaiting LT)(2.7%vs8.3%,p<0.01) at listing compared to those without TIPS. TIPS patients had lower LT rates(43.3%vs56.5%,p<0.01) and longer waitlist times(350vs113 d,p<0.01). TIPS use increased in Phase2(64.3%vs35.7%,p<0.01). Of 426 transplanted patients, 134(31.5%) received TIPS, showing lower MELD-Na scores(24vs27,p<0.01) and better medical conditions(Intensive care unit:14.9%vs21.9%,p<0.01) at LT. Status1 patients were fewer (3.7%vs12.3%,p<0.01), with longer waiting days(97vs26 d,p<0.01) in TIPS group. TIPS use at listing increased from Phase1(25.6%) to Phase2(37.7%). From Phase1 to Phase2, ascites severity improved, re-LT cases decreased(Phase1:9.8%vsPhase2:2.2%,p<0.01), and cold ischemic time slightly decreased(Phase1:7.0vsPhase2:6.4 hours,p=0.14). Median donor body mass index significantly increased. No significant differences were identified in patient/graft survival at 1-/5-/10-year intervals between phases or TIPS/non-TIPS patients. While 90-day waitlist mortality showed no significant difference(p=0.11), TIPS trended towards lower mortality(subHazard ratio[sHR]:0.70[0.45-1.08]). Multivariable analysis indicated that TIPS was a significant factor in decreasing mortality(sHR:0.45[0.27-0.77],p<0.01). TIPS group also showed significantly lower LT access(sHR:0.65[0.53-0.81],p<0.01). Multivariable analysis showed that TIPS was a significant factor in decreasing access to LT(sHR:0.60[0.46-0.77],p<0.01). Sub-group analysis excluding Status1 or HCC showed similar trends. Conclusion: TIPS in BCS patients listed for LT reduces waitlist mortality and LT access, supporting its bridging role.
