Accurate 3D printing for complex orthotopic liver transplantation

3D printing technology is increasingly being applied to the medical field. Professor Peng Zhihai, the director of the General Surgery Center of Shanghai First People's Hospital, recently used 3D printing technology to successfully print the liver simulation stereo model of donors, making doctors faster. A more complicated orthotopic liver transplantation was performed more accurately.

Zhihao from Guizhou is 10 years old and suffers from congenital autoimmune cirrhosis with portal hypertension. Hepatic function is seriously deficient and requires live liver transplantation. After matching, Zhihao's mother meets the transplant requirements.

How can we accurately develop a surgical plan? Experts think of 3D printing technology. After careful analysis and calculation, the expert team determined to remove 307 grams of liver from Zhihao mother.

During liver resection, the expert brings the model into the operating room and compares it in real time. By adjusting the 3D printed model and placing it in the best anatomical position, it provides intuitive real-time navigation for critical steps of the operation, and quick identification of key parts. Positioning; by accurately positioning the lesions and blood vessels, guiding the engagement of important vessels in real time, improving the accuracy of surgery and effectively reducing the risk of surgery.

The operation was very successful, Zhihao mother has been discharged smoothly, and Zhihao is currently in stable condition.
