    Abstract:
    BACKGROUND: Transjugular intrahepatic portosystemic shunt has been established as an effective treatment for complicated portal hypertension. This retrospective study investigated the effect of pretransplant transjugular intrahepatic portosystemic shunt placement on intraoperative graft hemodynamics and surgical outcomes after liver transplantation. METHODS: Of 1,081 patients who underwent liver transplantation between January 2007 and June 2017 at Cleveland Clinic (OH, USA), 130 patients had transjugular intrahepatic portosystemic shunt placement before liver transplant. We performed a 1:2 propensity score matching to compare intraoperative graft hemodynamics and surgical outcomes between the transjugular intrahepatic portosystemic shunt group (n = 130) and the no-transjugular intrahepatic portosystemic shunt group (n = 260). RESULTS: The transjugular intrahepatic portosystemic shunt did not increase operative time, the volume of blood transfusion, duration of hospital stay, or complication rates. Graft and patient survivals were similar between the groups. Mean intraoperative cardiac output and graft portal flow in the transjugular intrahepatic portosystemic shunt group were greater than in the no-transjugular intrahepatic portosystemic shunt group (P = .03 and P = .003, respectively). In multivariate analysis, male sex, younger age, low platelet count, absence of portal vein thrombosis, and pretransplant transjugular intrahepatic portosystemic shunt placement were independently associated with increased portal flow volume (P < or = 0.03 each). Transjugular intrahepatic portosystemic shunt malposition was observed in 17 patients (13.1%). The 1-year patient survival was 70.6% with transjugular intrahepatic portosystemic shunt malposition and 92.0% without transjugular intrahepatic portosystemic shunt malposition (P = .01). CONCLUSION: Our findings suggest that pretransplant transjugular intrahepatic portosystemic shunt placement increases graft portal flow but does not compromise surgical outcomes after liver transplantation. Transjugular intrahepatic portosystemic shunt malposition, however, is not uncommon and may increase the complexity of transplantation.
