Objective: Transjugular intrahepatic portacaval shunt (TIPS) is a traditional and effective treatment for variceal bleeding in cirrhotic patients with portal hypertension. However, in patients with a Budd-Chiari syndrome or other unaccessible hepatic veins, a direct puncture through the inferior caval vein may be inevitable. Direct intrahepatic portacaval shunt (DIPS) also has several advantages compared with TIPS. So we are expected to explore a digitalized model of DIPS and find the suitable shunt pathway of DIPS. Materials and Methods: We chose four hundred serial sectional images from the internal jugular vein superior margin to the edge interior hepatic from Chinese Visible Human Dataset. Surface and volume reconstruction were performed by 3D Doctor 3.5 software programs(ABLE SOFTWARE). Results: We reconstructed a digitalized model including liver and relevant vessels. It can display distribution characteristics and spatial structure relationship of intrahepatic vessels from any positions and angles. Conclusion: DIPS represents a useful addition to the endovascular techniques for managing complications of portal hypertension. The model of DIPS provides a good 3D morphological reference of image diagnostics and interventional therapy for DIPS.
