Transjugular intrahepatic portosystemic shunt creation using intravascular ultrasound vs fluoroscopic guidance: A dual-institution retrospective comparative study

Figure 2 Transjugular intrahepatic portosystemic shunt: a comparative analysis of patency and patient mortality between intravascular ultrasound guidance vs fluoroscopic guidance. A log-rank test was used for statistical comparison. A: Kaplan-Meier survival curves are shown for intervention-free survival (e.g. primary patency); B: Kaplan-Meier survival curves are shown for thrombosis-free survival (e.g. primary assisted patency) comparing the conventional fluoroscopic-guided transjugular intrahepatic portosystemic shunt (TIPS) and intravascular ultrasound-guided TIPS groups; C: Patient mortality following TIPS creation. Kaplan-Meier survival curves are shown for the conventional fluoroscopic-guided TIPS and intravascular ultrasound-guided TIPS groups following TIPS creation. iTIPS: Intravascular ultrasound-guided transjugular intrahepatic portosystemic shunt; cTIPS: Conventional fluoroscopic-guided transjugular intrahepatic portosystemic shunt.
