Post-traumatic cerebral vasospasm demonstrated by magnetic resonance angiography and perfusion-weighted imaging: a case report.

Much of the uncertainty regarding the true incidence and prognostic value of secondary ischemia from tSAH and VSP stems from the lack of diagnostic accuracy using transcranial Doppler sonography (TCD) fl ow velocities in the basal cerebral circulation or cumbersome imaging techniques (e. g. cerebral angiography, nuclear Abbreviations ▼ ACA anterior cerebral artery aSAH aneurysmal subarachnoid hemorrhage CBV cerebral blood volume CT computer tomography CTA computed tomography angiography DIND delayed ischemic neurological defi cit DWI diff usion-weighted imaging FLAIR fl uid attenuation inversion recovery HHH hypertension, hypervolemia, hemodilution ICA internal carotid artery MCA middle cerebral artery MR magnetic resonance MRA magnetic resonance angiography MRI magnetic resonance imaging PWI perfusion-weighted imaging SAH subarachnoid hemorrhage TBI traumatic brain injury TCD transcranial Doppler sonography tSAH traumatic subarachnoid hemorrhage TTP time-to-peak VSP cerebral vasospasm
