Development of a Virtual Stent Deployment Application to Estimate Patient-Specific Braided Stent Sizes

Annu Int Conf IEEE Eng Med Biol Soc. 2021 Nov:2021:4184-4187. doi: 10.1109/EMBC46164.2021.9629928.


A virtual stent deployment application was developed to estimate the appropriate and patient-specific size of a braided stent for patients who undergo endovascular treatment for intracranial aneurysms. Comparing between the simulated deployed and the actual stents, we evaluated the accuracy of the simulation results. Our results indicated that lengths of the virtual and actual stents matched well despite the actual stent being affected by a geometrical change of the parent artery.Clinical Relevance-Surgeons need to be well-experienced to select an appropriate braided stent size for endovascular treatment of intracranial aneurysms, because the actual length of the deployed stent changes. This simulation will be helpful to make tailor-made surgical planning regardless of the surgeons' individual skill level.
