Polycystic liver disease (PCLD) has long been considered to represent a contraindication to transjugular intrahepatic portosystemic shunt (TIPS) creation, primarily because of the risk of hemorrhage. Three-dimensional (3D) navigation within the enlarged and potentially disorienting parenchyma can now be performed during the procedure with the development of C-arm cone-beam computed tomography, which relies on the same equipment already used for angiography. Such a hybrid 3D reconstruction-enabled angiography system was used for safe image guidance of a TIPS procedure in a patient with PCLD. This technology has the potential to expedite any image-guided procedure that requires 3D navigation.
多囊肝疾病（PCLD）长期以来一直被视为经颈静脉肝内门体分流术（TIPS）的禁忌证，主要是因为存在出血风险。随着C型臂锥形束计算机断层扫描技术的发展，现在可以在手术过程中对增大且可能方位错乱的肝实质进行三维（3D）导航，该技术依赖于已用于血管造影的相同设备。这样一种具备3D重建功能的混合血管造影系统被用于对一名多囊肝疾病患者的TIPS手术进行安全的图像引导。这项技术有可能加快任何需要3D导航的图像引导手术。
