Core Tip

Core tip: The portacaval shunt using magnetic compression technique (MCT) was first established by our group in a canine model. Here, we assessed its feasibility in humans by analyzing computed tomography images and the anatomical parameters of cadavers. The average diameters of the portal vein (PV), the inferior vena cava (IVC) and the distances between the PV and the IVC were all within the parameters that allowed the setup of portacaval shunt using MCT. Finally, first stage simulation of the portacaval shunt was successfully set up in five cadavers. Our results indicated that the portacaval shunt is highly feasible in humans.
