Objective To renovate angiography in identifying portal vein anatomy during transjugular intrahepatic portosystemic shunt (TIPS) procedures,saving the time of TIPS procedures,decreasing the risk of the complications of the post-procedure.MethodsThe difference between the Wedge hepatic venography with Carbon Dioxide in 6 cases and Inferior Mesenteric artery angiography in 7 cases during TIPS procedures were compared in the identification of portal vein anatomy.The quality of images,their effects on the procedures,the complications and the recovery post-procedure were evaluated.Results Using CO2,the portal veins were opacified in all 6 cases.TIPS procedures succeeded in all cases except 1 case because of poor coagulation function.Using Inferior Mesenteric artery angiography,the portal veins were opacified in al1 7 cases.TIPS procedure succeeded in all cases except 1 case because of chronic portal occlusion.Puncture-site hematoma occurred in 1 case after TIPS procedure.ConclusionWedge hepatic venography with Carbon Dioxide is superior,safer and more convenient than Inferior Mesenteric Artery angiography in identifying portal vein anatomy during TIPS.
