Introduction to Department Application

In liver surgery cases, based on patient data obtained from medical examinations such as CT, the color and transparent liver model printed by the WJP direct-injection color multi-material 3D printing technology of Saina can accurately represent the overall shape of the liver, the lesion site, and clearly reproduce the liver interior The morphology of blood vessels and the shape of lesions help to simulate the surgical process before surgery, determine the approach of liver resection, the scope of resection, and calculate the remaining liver volume, and finally optimize the surgical plan.

Detailed case

Apply for a hospitalSouthern HospitalPatient conditionLGY, 56 years old, female
Condition descriptionDue to liver malignant tumors and cirrhosis, the liver is only 780CM3. Because liver function has serious defects, liver transplantation is currently the only effective treatment.
Surgery difficultiesLiver transplantation requires that the weight of the donor’s liver must be greater than or equal to 1% of the recipient’s body weight. Therefore, for such a precise operation, how big and what shape the donor liver is, how the two liver blood vessels and bile ducts are accurately anastomosed? The cutting method is very particular, cutting from the left or right side of the middle hepatic vein. The distance between the incision and the bifurcation of the blood vessel is very important to prevent the stenosis of the anastomosis, etc., which have extremely high requirements.
treatment planPreoperative planning was carried out according to the 3D printed donor and recipient liver three-dimensional models, the vasculature disconnection position, the donor cutting and separation method, etc. were specified, and the preoperative planning was strictly implemented during the operation, and the left liver of the donor was successfully transplanted to the recipient. body.
advantageAccording to the patient’s preoperative data, the data is reconstructed in three dimensions, and the surgical method and incision position are discussed with Professor Yang, and printed out in a 1:1 "physical" form, so that the lesion area and nearby organs can be accurately assessed before the operation Organize the three-dimensional spatial relationship, so as to formulate a detailed surgical plan, determine the surgical plan, and finally the operation is very successful.
