Sumario:INTRODUCTION: Understanding micro structures is important for the safety and reliable tumor resection for high grade glioma(HGG). The high-resolution 3-demension pre-operative simulation image (3D simulation imege) provides the useful information to the operators. We will report the outcome and the device of 3D simulation image at our single institute. MATERIAL AND METHOD: From April 2019 to July 2021, 56 cases of HGG (grade III: 18 cases, grade IV: 38 cases, initial cases: 49 cases, recurrent cases: 7) were included retrospectively. Zedview, Horos, and Freeform were used to create 3D simulation image from conventional clinical images as CT, MRI, and angiography. The evaluations of anatomical structures were 9 items: cerebral arteries (A), cerebral veins (V), perforators (Per), passing arteries (Pass), feeders (F), drainers (D), sylvian fissure vessels (SV), brain structures (B), and ventricles (Vent). After determining the necessity of 3D visualization for operative planning and evaluating whether it was possible to create the 3D image, the consistency with the anatomical structure and the usefulness for surgery were scored (Excellent 3 points / Good 2 points / Poor 1 point) respectively. RESULT: A: 56 out of 56 cases (100%) was judged as necessary, and the average score was 2.73 points. V: 56/56 cases (100%), 2.70 points. Per: 7/7 cases (100%), 1.80 points. Pass: 7/7 cases (100%), 2.86 points. F: 34/36 cases (94.5%), 2.56 points. D: 22/22 cases (100%), 2.36 points. SA: 7/7 cases (100%), 2.43 points. B: 53/54 (98.1%), 2.70 points. Vent: 27/28 cases (96.5%), 2.50 points. The average score of all structures was 2.59 points. DISCUSSION AND CONCLUSION: 3D imaging of the required anatomical structures was possible in almost all cases, and consistency and usefulness in most items were highly scored. Although the evaluation of the perforators was low, the 3D simulation image seemed to be useful for surgical planning.
