INTRODUCTION: The 3D printing model of the intrahepatic vessels and regional
anatomy are often used for navigation surgery. Here, we report the use of the
model for anatomical resection of hepatocellular carcinoma. PRESENTATION OF CASE:
Case 1: A tumor, 31mm in diameter, was located in segment 7 of the liver. Using
the 3D model, we identified the regional Glissonian pedicle and performed
resection of segment 7. Case 2: The tumor was located in segment 4/8 and involved
the middle hepatic vein. Radical resection of segment 4 and of the ventral area
of the right anterior section was performed using the 3D model. DISCUSSION: The
positional relationship between the intrahepatic vessels and liver tumors is the
most important factor for anatomical resection for hepatocellular carcinoma.
Therefore our simplified 3D model of intrahepatic vessels without liver
parenchyma is sufficient for effective guidance during surgery and has the
advantage of being feasible to use for all HCC surgeries. CONCLUSION: Use of 3D
printed models might have many merits and contribute to the great improvement of
the surgical quality.
