Computed Tomographic Blend Sign Is Associated With Computed Tomographic Angiography Spot Sign and Predicts Secondary Neurological Deterioration After Intracerebral Hemorrhage.
BACKGROUND AND PURPOSE Significant early hematoma growth in patients with intracerebral hemorrhage is an independent predictor of poor functional outcome. Recently, the novel blend sign (BS) has been introduced as a new imaging sign for predicting hematoma growth in noncontrast computed tomography. Another parameter predicting increasing hematoma size is the well-established spot sign (SS) visi...
متن کاملProspective validation of the computed tomographic angiography spot sign score for intracerebral hemorrhage.
BACKGROUND AND PURPOSE Intracerebral hemorrhage (ICH) results in high mortality and morbidity for patients. Previous retrospective studies correlated the spot sign score (SSSc) with ICH expansion, mortality, and clinical outcome among ICH survivors. We performed a prospective study to validate the SSSc for the prediction of ICH expansion, mortality, and clinical outcome among survivors. METHO...
متن کاملRisk factors for computed tomography angiography spot sign in deep and lobar intracerebral hemorrhage are shared.
BACKGROUND AND PURPOSE Patients with intracerebral hemorrhage (ICH) who present with a spot sign on computed tomography angiography are at increased risk of hematoma expansion and poor outcome. Because primary ICH is the acute manifestation of chronic cerebral small vessel disease, we investigated whether different clinical or imaging characteristics predict spot sign presence, using ICH locati...
متن کاملEvolution of computed tomography angiography spot sign is consistent with a site of active hemorrhage in acute intracerebral hemorrhage.
BACKGROUND AND PURPOSE CT angiography spot sign predicts hematoma expansion in patients with acute intracerebral hemorrhage (ICH). The spot sign may represent a site of active extravasation, a locus of arrested hemorrhage forming fibrin globes, or represent associated epiphenomena such as hypertensive microaneurysms. We sought to describe the evolution of spot signs over 60 seconds in acute ICH...
متن کاملClinical applications of the computed tomography angiography spot sign in acute intracerebral hemorrhage: a review.
S pontaneous intracerebral hemorrhage (ICH) is the most fatal form of stroke, with 1-month morality rates often exceeding 40% and rates of death or severe disability exceeding 75%. Nearly 20 years ago, the first observational studies demonstrated that hematoma volume on presentation was among the most potent predictors of survival and functional outcome. 3 Subsequent studies identified the freq...
