Abstract: Objective To evaluate the value of 320 row CT upper abdominal computed tomography angiography (CTA) in the follow up of transjugular intrahepatic portosystemic shunt(TIPSS) .Methods 21 cases after TIPSS therapy underwent upper ab-dominal CTA .Post-processing images ,including MPR ,VR ,MIP ,and CPR ,were used to determine the position and patency of the stent .The best images of the portal veins were obtained .Results Among the 21 cases ,CPR image clearly demonstrated endovascu-lar stent thrombosis in 3 cases(14 .29% ) with stent occlusion and 1 case(4 .76% ) with stent stenosis ;there were no stent stenosis or occlusion in 17 cases(80 .95% ) ,their CPR image showed the contrast agent was filled completely in the stent and no low-density thrombosis was found .The best phase of the portal vein was 45 s .Conclusion 320 row CT upper abdominal CTA can clearly dis-play the stent position and patency situation in patients ,therefore ,should be regarded as the first choice for the follow-up of patients after TIPSS therapy .
