title: Portal vein: US-guided localization prior to transjugular intrahepatic portosystemic shunt placement.
abstract: To mark the portal vein prior to transjugular intrahepatic portosystemic shunt (TIPS) placement, metallic coils adjacent to (n = 18) and a wire within (n = 18) the portal vein were placed with ultrasonographic (US) guidance. The mean number of punctures for successful portal vein entry was 3.0 with coils and 2.9 with a wire, and the mean total procedure time was 127.5 and 110.0 minutes, respectively (differences, not significant), and mean time at US was 20 and 10 minutes, respectively.
