AIM: To evaluate the effect of the shunting branch of the portal vein (PV) (left or right) and the initial stent position (optimal or suboptimal) of a transjugular intrahepatic portosystemic shunt (TIPS).

Patients were randomly divided into group A(stent in hepatic vein, n = 57), group B(stent extended to junction of hepatic vein and inferior vena cava, n = 136), group C(stent in left branch of portal vein, n = 83) and group D(stent in main portal vein, n = 149). Primary unassisted patency was compared using Kaplan-Meier analysis, and incidence of recurrence of bleeding, ascites and hepatic encephalopathy(HE) were analyzed.RESULTS The mean primary unassisted patency rate in group B tended to be higher than in group A at 3, 6 and 12 mo(P = 0.001, 0.000 and 0.005), and in group D it tended to be lower than in group C at 3, 6 and 12 mo(P = 0.012, 0.000 and 0.028). The median shunt primary patency time for group A was shorter than for group B(5.2 mo vs 9.1 mo, 95%CI: 4.3-5.6, P = 0.013, logrank test), while for group C it was longer than for group D(8.3 mo vs 6.9 mo, 95%CI: 6.3-7.6, P = 0.025, log-rank test). Recurrence of bleeding and ascites in group A was higher than in group B at 3 mo(P = 0.014 and 0.020), 6 mo(P = 0.014 and 0.019) and 12 mo(P = 0.024 and 0.034. Recurrence in group D was higher than in group C at 3 mo(P = 0.035 and 0.035), 6 mo(P = 0.038 and 0.022) and 12 mo(P = 0.017 and 0.009). The incidence of HE was not significantly different among any of the groups(P = 0.965).CONCLUSION The initial stent position can markedly affect stent patency, which potentially influences the risk of recurrent symptoms associated with shunt stenosis or occlusion.展开更多
