Portal vein access during transjugular intrahepatic portosystemic shunt creation was examined in 11 patients. Radiation metrics (kerma area product, reference point air kerma, and fluoroscopy times) during portal vein access were significantly greater for conventional versus intravascular US–guided transjugular intrahepatic portosystemic shunt (54.8 mGy ∙ cm2 ± 27.6 vs 8.4 mGy ∙ cm2 ± 5.0, P =.009; 210.4 mGy ± 109.1 vs 29.5 mGy ± 18.4, P =.009; 19.1 min ± 8.6 vs 8.9 min ± 4.6, P =.04). Wedged hepatic venography is a major contributor to radiation exposure. Intravascular US guidance is associated with significantly reduced radiation use.
