Wall shear stress in portal vein of cirrhotic patients with portal hypertension

Figure 1 Geometry of the portal vein system. A: Enhanced CT of the portal vein (PV) system; B: Geometry of the idealized PV model. SV: Splenic vein; SMV: Superior mesenteric vein; LPV: Left PV; RPV: Right PV.

Figure 2 Geometry of the patient-specific portal vein model. A: Healthy control; B: Cirrhotic patient with portal hypertension.

Figure 3 Wall shear stress distribution in right wall (A) and left wall (B) in the healthy control and portal hypertension groups. The X axis shows the length of the side wall of the PV, starting from 0 in the junction of SV and SMV. The Y axis shows WSS. SV: Splenic vein; SMV: Superior mesenteric vein.

Figure 4 Wall shear stress distribution in right wall (A) and left wall (B) for different superior mesenteric vein-splenic vein angles. The X axis shows the length of the side wall of PV, starting from 0 in the junction of SV and SMV. The Y axis shows WSS. SV: Splenic vein; SMV: Superior mesenteric vein.

Figure 5 Wall shear stress distribution in right wall (A) and left wall (B) for different portal vein-splenic vein angles. The X axis shows the length of the side wall of PV, starting from 0 in the junction of SV and SMV. The Y axis shows WSS. SV: Splenic vein; SMV: Superior mesenteric vein.
