Abstract:
Objective To explore the clinical application value of three-dimensional visualization of blood vessels as the axis and virtual reality technology in giant liver cancer.Methods Thin-layer CT image data of 13 patients who were diagnosed as giant primary liver cancer were collected for three-dimensional reconstruction,and then transformed into VR model.The anatomical relationship between the tumor and its surrounding important structures was analyzed.The preoperative evaluation,classification and surgical planning based on blood vessels as the axis were carried out to guide intraoperative navigation.The consistency was verified by the intraoperative rapid pathological examination.Results 13 patients successfully achieved 3D reconstruction and VR model transformation.According to the 3D visualization classification of blood vessels as the axis.There were three cases of type Ⅰ a grade 1,two cases of type Ⅰa grade 2;one case of type Ⅱ a grade 2;one case of type Ⅱ b grade 3;two cases of type Ⅱ c grade 3;four cases of type Ⅱ a grade 3.Conclusions Three-dimensional visualization and VR technology can provide comprehensive information on the anatomical structure of liver cancer lesions and blood vessels,which is of great value in the application of giant liver cancer surgery.
