Abstract:
Objective To investigate the prognosis and prognostic risk factors of hepatic artery complications after orthotopic liver transplantation (OLT) treated with the interventional techniques.Methods The clinical data of 21 patients with hepatic artery complication after liver transplantation receiving thrombolysis, PTA, and stent placement in our institute from November 2003 to April 2007 were retrospectively analyzed. Based on the prognosis of grafts, 21 patients were divided into poor-prognosis group and non-poor-prognosis group. Fifteen variables (including biliary complication, hepatic artery restenosis,early or late artery complication, and so on) were analyzed in both groups with binary logistic regression analysis to screen out the risk factors related to prognosis of percutaneous interventional treatment for hepatic artery complications after OLT. Results Twenty-one patients were followed for mean 436 days, median 464 days (3-1037 days). The poor-prognosis group included 11 patients (5 cases received retransplantation, and 6 died). The mean survival time of grafts in poor-prognosis group was 191 days, and median survival time was 73 days (3-616 days). The mean survival time of grafts in non-poor-prognosis group which included 10 patients was 706 days, and median survival time was 692 days (245-1037 days).Univariate analysis showed there were significant difference in biliary complication, total bilirubin and indirect bilirubin between the two groups. The binary logistic regression analysis showed the risk factor related to prognosis was with biliary complication before the interventional management (P = 0.027, OR =22.818). Conclusion Biliary complication before interventional management is the risk factor related to poor prognosis of patients with hepatic artery stenosis or thrombisis receiving interventional treatment.
