Model of the Venous System for Training Endovascular Treatment in Interventional Neuroradiology

Background: Endovascular treatment of venous disease is introducing new therapeutic options in neuroradiology. These procedures are technically challenging and require extensive physician training. Currently, training is mainly conducted on animal models, which presents drawbacks such as ethical concerns and anatomical differences from human vascular architecture. There is no training model that simulates treating intracranial venous disease using original instruments in a real angiography suite. Methods: This work presents the development of a venous system model for endovascular training simulations for integration into the existing Hamburg ANatomical NEurointerventional Simulator (HANNES) for arterial interventions. Results: The manufacturing process established at HANNES and the material used for the arterial vascular models were successfully transferred to the larger 3D-printed vein models. The application test was conducted in a real angiography suite with original instruments by an experienced neurointerventional physician to evaluate the system in terms of geometric mapping, flow, haptics and probing. Conclusion: This newly developed model provides a first approach to simulate an endovascular intervention in the venous system within the HANNES environment. Future expansions might include specific treatment simulations for conditions such as arteriovenous malformations, dural arteriovenous fistulas, sinus vein thrombosis and hydrocephalus.
