ABSTRACT
Objective To explore the clinical application of 3D-printing model in guiding interventional management of Budd-Chiari syndrome (BCS) and in teaching practice.Methods A patient with typical BCS of inferior vena cava type was selected.By using MR enhanced scanning,the original MRA data of DICOM format were extracted,and then the digital data were extracted and reconstructed to obtain 3D BCS model by Simpleware software.The 3D BCS entity model,using 1 ∶ 1 ratio,was printed out by a 3D printer.An experienced chief physician made a simulated interventional manipulation on this 3D BCS entity model.Results The BCS 3D model was successfully printed.Simulated operation could be easily performed on the 3D-printing model,in this way the chief physician could make a demonstration of interventional procedure of BCS to the junior doctors and medical students.Interventional therapeutic manipulation for BCS could be well demonstrated on the 3D-printing model of BCS,which was very helpful in guiding teaching practice and in promoting the communication between doctors and patients.Conclusion The BCS 3D-printing model can truly reflect the spatial architecture features of the inferior vena cava and the hepatic veins,which are very valuable for the making of surgical plan,for the demonstration of simulation operation,and for teaching practice.Moreover,3D-printing model can stereoscopically display the location and morphology of the lesion,which can improve patient's understanding of the disease,thus,the communication between doctors and patients can be strengthened.
ABSTRACT
@#Objective To build a method of mandible 3D model to measure and analysis, then to finish the operation simulation, providing anatomic data to avoiding the complicafious of mandible osteotomy. Methods Using CT data to reconstruct 3D model of mandible with blood vessel and bone, then using Simpleware to measure and analysis, and using Freeform system and an incision method of Boolean to simulation mandible osteotomy safely. Re, tits It was possible to use CT data to rebuild 3D model for 3D measure and analysis for operation simulation. The inferior alveolar artery and never were the main tiasues which went through the madibhilar. The length of mandibular foramen to anterior minus was (19.13±0.66) ram,and the ones to posterior ramus was (18.96± 0.64)mm. The angle of the mandible was (109.70±4.67)°. The rages of the remus for safe operation was (12.62±0.28)mm, and the safe rages about angle of the body and bottom of the mandible was (22.30±4.67)°. There were obvious differences from children to the aged in the mandible physiological and anatomic study. We can use Freeform system to simulate the operation on 3D model. Conclusion It is a new method to build 3D model and use Freefonn system to simulate operation and a new path to communion with patients for a good operation.
