Balloon occlusion versus wedged hepatic venography using carbon dioxide for portal vein opacification during TIPS.
Balloon occlusion hepatic venography using carbon dioxide (CO2) is proposed as a safer yet simpler alternative to wedged catheter techniques that have caused hepatic lacerations during the transjugular intrahepatic portosystemic shunt (TIPS) procedure. The image quality of CO2 wedged catheter and balloon occlusion venograms was comparable in our small series, with no venographic-related complications occurring in the balloon occlusion group.
