Cortical Venous Changes on Susceptibility-Weighted Imaging Predict the Cerebral Collateral Circulation as Confirmed by Digital Subtraction Angiography.

Asymmetrical cortical vein sign (ACVS) shown on susceptibility-weighted imaging (SWI) can reflect regional hypoperfusion. We investigated if ACVS could predict the cerebral collateral circulation (CC) as assessed by digital subtraction angiography (DSA) in acute ischemic stroke patients with ipsilateral severe stenosis/occlusion of the anterior circulation. Clinical data and imaging data of 62 acute ischemic stroke patients with ipsilateral severe stenosis or occlusion of the anterior circulation confirmed by DSA were collected retrospectively.

Asymmetrical cortical vein sign predicts early neurological deterioration in acute ischemic stroke patients with severe intracranial arterial stenosis or occlusion.

Background: Susceptibility weighted imaging (SWI) provides an approximate assessment of tissue perfusion and shows prominent hypointense cortical veins in the ischemic territory because of the 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).

Methods: One hundred and nine acute ischemic stroke patients with SIASO who underwent SWI were retrospectively recruited.

Does the Babinski sign predict functional outcome in acute ischemic stroke?

Objective: The aim of this prospective cohort study was to determine the incidence and neuroimaging risk factors associated with Babinski sign following acute ischemic stroke, as well as its relationship with the functional outcome of patients.

Methods: A total of 351 patients were enrolled in the study within 7 days of acute ischemic stroke. The Babinski sign along with other upper motor neuron signs were examined upon admission and between days 1 and 3 and days 5 and 7 after admission.

Anxiety in Patients With Acute Ischemic Stroke: Risk Factors and Effects on Functional Status.

Anxiety is prevalent after a stroke. The pathophysiological mechanisms underlying the development of poststroke anxiety (PSA) remain unclear. The aim of this study was to investigate the clinical and neuroimaging risk factors for development of PSA and examine the effects of PSA on activities of daily living (ADL) and quality of life (QOL) in Chinese patients with ischemic stroke.

Severe Lesions Involving Cortical Cholinergic Pathways Predict Poorer Functional Outcome in Acute Ischemic Stroke.

Background and Purpose- The aim of the study was to assess the effect of lesion severity in cortical cholinergic pathways in acute ischemic stroke patients on functional outcomes. Methods- The study sample consisted of 214 men (70.9%) and 88 women (29.

Intracranial Atherosclerosis and Poststroke Depression in Chinese Patients with Ischemic Stroke.

Background: Intracranial atherosclerosis (ICAS) is a common etiology of ischemic stroke in Chinese patients, probably leading to regional hypoperfusion in the brain. The purpose of this prospective study was to investigate the association between ICAS and poststroke depression in Chinese patients with ischemic stroke.

Methods: During the study period, a total of 569 patients aged between 40 and 80 years with acute ischemic stroke were consecutively admitted and screened.

Poststroke fatigue: risk factors and its effect on functional status and health-related quality of life.

Background: Fatigue is a common problem in ischemic stroke survivors. The mechanisms of poststroke fatigue are uncertain yet. The effects of it on functional status have rarely been studied.
