Abstract

The feasibility of a radiofrequency (RF) wire to replace the needle trocar for the creation of a transjugular intrahepatic portosystemic shunt (TIPS) was assessed in 3 swine by using fluoroscopy and intravascular ultrasonography (IVUS). RF wire passes were successful from hepatic to portal vein and from inferior vena cava to portal vein. Technical success was achieved using both IVUS guidance and carbon dioxide portography. The wire tracked a straight course under RF energy application without subjective deflection and, when centrally advanced, served as the working wire for completing the TIPS in 2 attempts with stent graft deployment. No procedural adverse events from the use of RF wire were observed.
