| 目的 评价利用Xper-CT与CT门静脉造影（CTPV）融合图像作为经颈静脉肝内门腔静脉内分流术（TIPS）中三维路径图的可行性。方法 收集门静脉高压症患者37例，其中21例接受常规TIPS术患者，另16例接受3D路径图下引导TIPS，采集动静脉期和门静脉期图像，对3D路径图下引导TIPS患者在肝脏部位行Xper-CT扫描，在三维工作站中利用"Multi-Modality Matching"功能进行两者图像融合，作为实时透视过程中的三维路径图。结果 Xper-CT与CTPV在融合过程中，骨性对位误差均<2.00 mm；术中门静脉CTPV图像与透视的图像的匹配误差稍大，其中15例上下误差>2.00 mm，1例左右误差>5.00 mm。结论 将Xper-CT与CTPV的融合图像作为TIPS的三维路径图，可在不使用对比剂的情况下，术中多角度观察穿刺针与门静脉的位置关系，提高穿刺的定位准确性和安全性，减少手术时间。 |

| 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. |
