Asymmetrical Cortical Vein Sign Predicts Early Neurological Deterioration in Acute Ischemic Stroke Patients with Severe Intracranial Arterial Stenosis or Occlusion
Abstract:Background: Susceptibility weighted imaging (SWI) provides a rough assessment of tissue perfusion with the prominent hypointense cortical veins in the ischemic territory due to increased concentration of deoxyhemoglobin. We aimed to evaluate whether asymmetrical prominent cortical vein sign (APCVS) on SWI can predict early neurological deterioration (END) in acute ischemic stroke patients with severe intracranial arterial stenosis or occlusion (SIASO).Results: One hundred and nine acute ischemic stroke patient… Show more
