A new method of 3D printing an anatomically accurate replica of the human liver is now helping to guide surgeons during tricky procedures.
The 3D-printed replicas, which are made of transparent material threaded with colored arteries and veins, could help surgeons prevent complications when performing liver transplants or removing cancerous tumors, researchers said.
“We provide the surgeons with a physical model that is 100 percent identical to what they will encounter in surgery when they operate,” said Dr. Nizar Zein, the chief of hepatology at the Cleveland Clinic in Ohio. “It takes away some of the potential surprises that will be found at the time of surgery.”
The new liver replica could also be used to train medical students in the techniques needed for surgery, Zein said. … (Read more)
