Three-dimensional C-arm CT-guided transjugular intrahepatic portosystemic shunt placement: feasibility, technical success and procedural time

Objectives Establishment of transjugular intrahepatic portosystemic shunts (TIPS) constitutes a standard procedure in patients suffering from portal hypertension. The most difficult step in TIPS placement is blind puncture of the portal vein. This study aimed to evaluate three-dimensional mapping of portal vein branches and targeted puncture of the portal vein.
