title: Transjugular intrahepatic portosystemic shunt creation using a three-dimensional fluoroscopy guidance system in patients with the Budd-Chiari syndrome.
abstract: When performed for Budd-Chiari syndrome (BCS), transjugular intrahepatic portosystemic shunt (TIPS) creation can be technically difficult due to hepatic congestion and asymmetric hypertrophy. We present three female patients with decompensated BCS in whom TIPS were created using a three-dimensional fluoroscopy guidance system. On a dedicated workstation using three-dimensional volumes of computed tomography imaging, a virtual needle path was created by the operator extending from the needle entry point (hepatic vein stump or inferior vena cava) to the target portal vein. Subsequently, the virtual needle path was overlaid on the fluoroscopy image for guidance of portal venous cannulation. This technology can be used for TIPS procedures in patients with BCS and other complex TIPS cases, as it may help delimit the trajectory of the needle pass and optimally result in more efficient procedures with decreased radiation dose.
