Figure 4 Characteristics of intrahepatic blood flow in the healthy side before and after operation(A) Before surgery, the outlet of RHV was also invaded and almost occluded, and the intrahepatic blood flowed back into the infrahepatic vena cava through the SHV after circling through the hepatic vein network in the right liver, and then flowed back to the right atrium through the vertebral venous plexus. (B) The SHV, RHV, and PV were well connected, so the SHV was sutured and closed. Postoperative blood flow was infrahepatic, and intrahepatic blood was flowed flowing directly into the right atrium through the paravertebral venous plexus. Intrahepatic blood was flowing out of the liver through the reconstructed RHV and flowing into the right atrium through the suprahepatic vena cava.
