Purpose. To evaluate experience of using intraoperative navigation with the help of Avtoplan system developed at Samara State Medical University on the basis of modeling data of computer and magnetic resonance imaging in a patient with an intraventricular tumor.

Materials and methods. Based on the performed tomographic studies, segmentation was performed in Avtoplan system: skull bones, brain matter, ventricles were distinguished. During the operation, navigation was used: with the help of stereo cameras the obtained model was combined with the patient’s body, and with the help of an instrument the optimal trajectory of movement was determined.

Results. Postoperative period passed without complications, no MR data for residual tissue was obtained. During the operation, surgeons noted greater convenience in the localization of the neoplasm, a smaller incision and traumatization of the brain substance, a shorter duration of the operation and the absence of the need for intraoperative imaging.
