Abstract:
Objective To investigate the impacts of preoperative portal vein thrombosis (PVT) on intraoperative or postoperative parameters in patients receiving orthotopic liver transplantation (OLT). Methods The clinical data of 836 patients undergoing OLT in our hospital from February 2002 to February 2007 were retrospectively analyzed. Of the 836 patients, 71 had preoperative PVT (PVT group) and the other 765 had not (control group). Intraoperative patameters (operative dura-tion, anhepatic phase duration, blood transfusion volume) and postoperative parameters (ICU stay and hospitalization time, portal rethrombosis posttransplantation, graft function, portal vein flow, death rate in perioperation and 1-, 3-, 5-year survival rate) were compared between the 2 groups. Results The operative duration and anheptic phase duration were significantly higher in the PVT group than in the control (792. 47±62. 29 min vs 516. 18±86. 30 min, P<0. 01, 77. 53±24. 76 min vs 48. 55±31. 20 min, P<0. 05). Perioperative blood transfusion volume, average ICU stay and hospitalization duration were not significantly different between the 2 groups. The incidence of postoperative portal rethrombosis was remarkably higher in PVT group than in the control (9. 86% vs 1. 44% , P<0. 01).No significant differences in the graft function and portal vein flow (PVF) between the 2 groups except for a higher PVF in the PVT group on the 90th d(41. 43±17. 19 vs 19. 85±11. 39, P<0. 05). We noticed slightly higher death rate in perioperative and lower 1-, 3-, 5-year survival rate in the PVT group. Conclusion Preoperative PVT can gain the same favorable outcomes as in those without PVT in spite of readily intraoperative complex.
