Application of 3D-printing technique in interventional treatment of Budd-Chiari syndrome: a preliminary study / 介入放射学杂志

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.
