Shunting branch of portal vein and stent position predict survival after transjugular intrahepatic portosystemic shunt

Figure 1 Stent position classifications. The initial stent position was classified according to the angiography imaging as follows: A: Suboptimal in the hepatic vein (HV) (arrow) and optimal in the portal vein (PV) (arrow head); B: Optimal in the HV (arrow) and suboptimal in the PV (arrow head); C: Optimal in the HV (arrow) and optimal in the PV (arrow head).

Figure 2 Selection flowchart for the consecutive patients who underwent transjugular intrahepatic portosystemic shunt between March 2001 and July 2010. TIPS: Transjugular intrahepatic portosystemic shunt.

Figure 3 Hepatic encephalopathy results from the Kaplan-Meier analyses. Comparison of hepatic encephalopathy between the patients with a transjugular intrahepatic portosystemic shunt (TIPS) to the left portal vein (PV) and those with a TIPS to the right PV in all patients (A), an 8-mm stent subgroup (C) and a 10-mm stent subgroup (E). Comparisons of survival between the patients with a TIPS to the left PV and those with a TIPS to the right PV in all patients (B), an 8-mm stent subgroup (D) and a 10-mm stent subgroup (F).

Figure 4 Patency results from the Kaplan-Meier analyses. Comparison of primary patency between patients with optimal initial stent position (O-SP) and those with sub-O-SP in all patients (A), an 8-mm stent subgroup (C) and a 10-mm stent subgroup (E). Comparisons of survival between the patients with O-SP and those with sub-O-SP in all patients (B), an 8-mm stent subgroup (D) and a 10-mm stent subgroup (F).

Figure 5 Patency results in patients with different stent positions. Comparison of primary patency between patients with optimal initial stent position (O-SP) and those with sub-O-SP in the hepatic vein (HV) only, sub-O-SP in the portal vein (PV) only and sub-O-SP in both the HV and PV.

Figure 6 Relationship between stent positions and stenosis/occlusion sites. The stenosis/occlusion sites of the first shunt dysfunction among patients with optimal initial stent position (O-SP) in the hepatic vein(HV) and portal vein (PV), patients with sub-O-SP in the HV and patients with sub-O-SP in the PV are significantly different.
