Spleen stiffness accurately tracks early and sustained portal pressure changes after transjugular intrahepatic portosystemic shunt

Figure 4 Correlation analyses between spleen stiffness measurement before transjugular intrahepatic portosystemic shunt placement/Δ spleen stiffness measurement and portocaval pressure gradient before transjugular intrahepatic portosystemic shunt placement/Δ spleen stiffness measurement. A: Spleen stiffness measurement before transjugular intrahepatic portosystemic shunt placement exhibited a moderate positive correlation with Portocaval pressure gradient before transjugular intrahepatic portosystemic shunt placement (pre-PPG) (r = 0.41, P < 0.001); B: Δ Spleen stiffness measurement was strongly negative correlated with ΔPPG (r = -0.57, P < 0.001). Pre-PPG: Portocaval pressure gradient before transjugular intrahepatic portosystemic shunt placement; Pre-SSM: Spleen stiffness measurement before transjugular intrahepatic portosystemic shunt placement; Pre-LSM: Liver stiffness measurement before transjugular intrahepatic portosystemic shunt placement.
