New insights of the adaptation of flow diverters to the local geometry of vessel in the treatment of intracranial aneurysms.

Purpose: It is unclear how flow diverters (FD) and vessels interact in the treatment of intracranial aneurysms. In this study, we examine the local changes in artery and device morphology caused by their mutual interaction.

Methods: Pre-treatment 3DRA and post-treatment XperCT or DynaCT images were collected retrospectively from 25 patients.
