The first experience of using 3-D printed models of intracranial arteries in training and teaching endovascular neurointerventions

Rationale: Endovascular intervention is often the first-line treatment for patients with intracranial artery pathology. Specialists performing therapeutic interventions on cerebral vessels must have practical training, since the cost of error is extremely high. For this reason, these interventions are performed by residents and interns less often than other endovascular surgeries. Printing of 3D models is a unique educational tool that can improve the effectiveness of training in endovascular techniques. However, to date, the role of this new technology in training specialists, as well as the features of its application, have not been sufficiently covered.Objective: to analyze the effect of 3D printing of an individually recreated digital model of vascular structures of the brain on the results of training and education in the technical aspects of endovascular neurointerventions.
