Computational models constructed from PC-MRI and MRA
data can be used to predict flow fields resulting from
vascular interventions. Interventional treatment of
basilar aneurysms is particularly challenging since
these lesions cannot be completely removed from the
circulation without sacrificing flow to the vital
pontine perforators. We report on image-based,
patient-specific flow simulations in vascular geometries
resulting from alternative virtual surgeries on fusiform
and giant aneurysms of the basilar artery. The effect of
the proposed flow revisions on patency of the pontine
perforators is evaluated by simulating virtual contrast
transport. This information, available a priori, may be
helpful in clinical decision-making.
