CT Angiography Spot Sign, Hematoma Expansion, and Outcome in Primary Pontine Intracerebral Hemorrhage.
BACKGROUND AND PURPOSE The computed tomography angiography (CTA) spot sign is a validated predictor of hematoma expansion and poor outcome in supratentorial intracerebral hemorrhage (ICH), but patients with brainstem ICH have typically been excluded from the analyses. We investigated the frequency of spot sign and its relationship with hematoma expansion and outcome in patients with primary pon...
متن کاملDefining the CT angiography 'spot sign' in primary intracerebral hemorrhage.
PURPOSE The computed tomogram angiography (CTA) 'spot sign' describes foci of intralesional enhancement associated with hematoma expansion in primary intracerebral hemorrhage patients. A consistent radiological definition is required for two proposed recombinant Factor VIIa trials planning patient dichotomization according to 'spot sign' presence or absence. We propose radiological criteria for...
متن کاملCT angiography "spot sign" predicts hematoma expansion in acute intracerebral hemorrhage.
BACKGROUND AND PURPOSE Morbidity and mortality in spontaneous intracerebral hemorrhage (ICH) are correlated with hematoma progression. We hypothesized that the presence of tiny, enhancing foci ("spot sign") within acute hematomas is associated with hematoma expansion. METHODS We prospectively studied 39 consecutive patients with spontaneous ICH by computed tomography angiography within 3 hour...
متن کاملAnatomic pattern of intracerebral hemorrhage expansion: relation to CT angiography spot sign and hematoma center.
BACKGROUND AND PURPOSE We sought to identify baseline determinants of the anatomic pattern of hematoma expansion in patients with intracerebral hemorrhage and spot sign. METHODS We coregistered baseline and follow-up CT scans from 15 intracerebral hemorrhage patients and measured growth at each surface node from baseline to follow-up hematoma. We analyzed the effects of proximity to the spot ...
متن کاملThe Spot Sign Predicts Hematoma Expansion, Outcome, and Mortality in Patients with Primary Intracerebral Hemorrhage
OBJECTIVE The purpose of this study was to retrospectively review cases of intracerebral hemorrhage (ICH) medically treated at our institution to determine if the CT angiography (CTA) 'spot sign' predicts in-hospital mortality and clinical outcome at 3 months in patients with spontaneous ICH. METHODS We conducted a retrospective review of all consecutive patients who were admitted to the depa...
