Effect of technical parameters on transjugular intrahepatic portosystemic shunts utilizing stent grafts

Figure 1 Digital substraction angiography showing the placement of the hepatic venous end of the transjugular intrahepatic portosystemic shunt stent. A: Hepatic venous end of the stent at the hepatocaval junction (short arrow); B: Placement of the hepatic venous end of the stent away from the hepatocaval junction (arrow denotes end of stent, arrowhead denotes hepatocaval junction, and triangle denotes unstented hepatic vein).

Figure 3 Kaplan-Meier curves following placement of a transjugular intrahepatic portosystemic shunt using a stent-graft when the stent-to-inferior vena cava distance was less than or equal to 1. 5 cm and more than 1.5 cm. A: Primary patency as a function of time; B: Time to recurrence of symptoms as a function of time; C: All-cause mortality as a function of time.
