After extracting the native liver from the anesthetized recipient mouse, gently grasp the recipient's liver portal vein or PV edge using pen forceps and secure it with a vice. Pass an eight oh silk thread around the PV and place a vascular clamp on it. Create a one fourth circumferential section approximately 0.5 millimeters from the PV edge.
While passing saline through the hole, use a specialized instrument to enlarge the hole. Grip the cuff handle using straight forceps and insert it into the lumen. Then secure the cuff with an 8.0 silk thread.
Remove the vascular clamp from PV to allow reperfusion of the liver. Finally, carefully release the pen forceps to complete the PV reconstruction. After positioning the liver lobe, Move the pen forceps attached to the recipient IHIVC dorsal to the graft's right lower lobe.
Then secure the IHIVC with a vice. Rub away any remaining liver tissue around the recipient's IHIVC with a cotton swab. Pass an 8.0 silk thread around the recipient's IHIVC.
Create a one fourth circumferential section, approximately 0.5 millimeters from the recipient's IHIVC edge. After flushing the lumen with saline, insert the cuff into the IHIVC lumen. Carefully secure the cuff with an 8.0 silk thread.
Finally, remove the vascular clamp and pen forceps. The preservation of the graft at cold temperatures for one hour resulted in serum alanine aminotransferase levels, averaging approximately 2000 units per liter at six hours post reperfusion. A survival rate of 100%was observed at seven days following transplantation.
