ABSTRACT
Objective: To investigate the application value of 3D visualization technique in the precise surgery for complex sacra tumor. Methods: A 59-year-old female patient with the sacrum occupying for half a month was enrolled in the research. And then the original data of digital imaging and communication in medicine (DICOM), that were obtained through CT and MRI, were imported in computer to reconstruct 3D spatial model. Results: The reconstructive model that used 3D technique can not only clearly display the size of sacral tumor, but also reflect the anatomic morphology, the blood supply of tumor and the relationship between tumor and surrounding tissues. Under its guidance, the tumor could be completely removed, and the surrounding normal organs and nerve roots could be preserved as much as possible. Besides, the operation time was greatly decreased and the amount of bleeding was reduced. Conclusion: The application of 3D visualization technique in the surgical treatment for sacral tumor can enhance the safety of the tumorectomy of sacral tumor, and accelerate the operation speed, and increase the accuracy of operation, and protect vital organs and nerves, thus preserve the corresponding physiological function. Therefore, it has great application prospect in the precisely surgical treatment of spinal surgery.
