Abstract:
Objective To explore the feasibility of fusion image of Xper-CT and CT portal venography (CTPV) as DSA 3D-roadmap in operation of transjugular intrahepatic portosystemic stent shunt (TIPS).Methods Thirty-seven patients with portal hypertension were enrolled in this study,among them 21 underwent conventional TIPS retrospectively,16 underwent Xper-CT and CTPV imaging to obtain fusion image in the workstation with the software of Multi-Modality Matching for hepatic portal vein without contrast medium administration.Then the fusion image was used as the 3D-roadmap in the process of real-time fluoroscopy.Results In the fusion process of Xper-CT and CTPV,osseous registration error was ＜ 2.00 mm,while error of the portal vein fusion image and the real-time X-ray image displacement were ＞2.00 mm between up and down in 15 patients,＞5.00 mm between left and right in 1 patient.Conclusion Xper-CT with CTPV fusion image can be used as 3D-roadmap of TIPS to observe the relationship between puncture needle and the portal vein without administration of contrast medium,improving the accuracy and safety of puncture and reducing operation time.
