Patient-specific models of the human vessels could be used for the different purposes varying from the visualization of a vasculature to examination of a strategy of the endovascular treatment.

Current work represents a step by step workflow of the production of vascular models: optimisation of the geometry of the digital model, design of the connectors, wall thickness of the model etc. The flow in the models was compared with in vivo flow data of the patient.

The influence of different flow diverter stents on the flow in the model with an aneurysm was evaluated with MRI (TOF and 4D Flow).
