What imaging technique could be used to assess any possible residual perfusion of the aneurysm?
DSA is the gold standard. MRI can be performed with MRA sequences optimized for low susceptibility to metallic artefacts.
CCT two weeks after treatment shows interval placement of external ventricular drainage and coiling of MCA aneurysm.
There is interval resolution of the intraparenchymal hematoma in the frontal lobe with residual cystic-gliotic changes noted.
Partial resolution of most subarachnoid hemorrhage, with some residual blood in the sulci near the vertex (high frontal and parietal lobes).
Partial resolution of most intraventricular hemorrhage, with some residual blood in both lateral ventricles.
Resolution of hydrocephalus with normalization of configuration and width of both lateral ventricles and the third ventricle.
CTA shows strong metal artefacts near the coils, any possible residual perfusion of the aneurysm cannot be fully assessed.
