Abstract：Objective To explore the feasibility and clinical value of mixed reality technology in guiding external ventricular drainage(EVD).Methods Fifty patients(23 cases of cerebral hemorrhage,27 cases of hydrocephalus)who needed EVD were prospectively collected from January 2022 to June 2023(observation group),and 50 patients(26 cases of cerebral hemorrhage,24 cases of hydrocephalus)who underwent traditional EVD from June 2020 to December 2021 were selected as the control group.In the observation group,the DICOM data of head CT and MRI were imported into the 3D Slicer software for the surgical planning before operation,and then the model files were imported into the head-mounted mixed reality holographic imaging equipment using the browser to guide puncture according to the holographic projection of the surgical path.In the control group,the surgical plan was made according to the CT images before operation,and the blind puncture was performed according to the body surface marks during operation.Results All 50 patients in the observation group successfully completed the operation.The distance between the tip of the drainage tube and the target point in the observation group[(4.43±1.37)mm]was significantly smaller than that[(10.41±3.42)mm]in the control group(P<0.001).In the observation group,the puncture accuracy of Kakral grade 1 was achieved in 47 cases(94.00%),and grade 2 in 3 cases(6.00%).In the control group,the puncture accuracy of Kakral grade 1 was achieved in 39 cases(78.00%),grade 2 in 9 cases(18.00%),and grade 3 in 2 cases(4.00%).The puncture accuracy of Kakral grade in the observation group was significantly better than that in the control group(P=0.048).There was no statistically significant difference in the success rate of one puncture between the observation group(98.00%)and the control group(88.00%;P=0.117).Conclusions Mixed reality technology can be used to guide EVD,which can improve the accuracy of catheterization.
