Abstract: Objective:To investigate the feasibility and safety of endoscopic ultrasound (EUS)-guided intrahepatic portal vein puncture through jugular vein implantation in transjugular intrahepatic portosystemic shunt (TIPS).Methods:As research subjects, 5 beagle dogs were anesthetized, and EUS was placed through the jugular vein to observe the intrahepatic portal vein. Under real-time guidance, the portal vein was punctured and a stent was placed to complete the TIPS.Results:Among the 5 beagles, EUS was unable to be placed in 1 due to the small diameter of the external jugular vein, and it was implanted successfully in 4 others through the external jugular vein who underwent real-time guidance of portal vein puncture. Subsequent stent placement and balloon dilation were completed. All animals survived after the experiment.Conclusion:EUS-guided intrahepatic portal vein puncture through jugular vein implantation is safe and feasible in TIPS.
