Background Purpose: Whether altered cerebral perfusion is associated with the pathogenesis of single subcortical infarctions (SSIs) in the lenticulostriate artery (LSA) territory remains unclear.

Objective: We aimed to assess whether cerebral perfusion abnormalities are related to LSA impairments in the subacute phase of SSIs and then to examine their correlations with etiological subtypes of SSIs.

Methods: A total of 110 patients with acute SSIs in the LSA territory were prospectively recruited between July 2017 and October 2021, and they underwent magnetic resonance perfusion-weighted imaging (PWI) and whole-brain vessel-wall imaging (VWI) within 7 days of stroke onset.

Objective: To investigate the monitoring effect and application of transcranial Doppler ultrasound (TCD) in patients with severe neurovascular cerebrovascular diseases.

Methods: From December 2016 to October 2018, 96 patients with cerebrovascular disease in Department of Neurology and ICU, West China Hospital, Sichuan University were monitored by bedside TCD, including the detection of bilateral middle cerebral arteries (MCAs) through temporal window, and the detection of the basilar artery (BA) through occipital window, characterized by the peak systolic blood flow velocity, peak diastolic blood flow velocity, average peak blood flow velocity, vascular pulsatility index, vascular pulsatility index, vascular resistance index and blood flow spectrum morphology in local hemodynamic changes. According to the monitoring results, it was divided into vasospasm group, increased blood flow group and insufficient blood supply group.

Background: Improved prognostication during the acute phase of intracerebral hemorrhage (ICH) could influence goals of care. We investigated the utility of diffusion tensor imaging (DTI)-derived data obtained during the acute phase of ICH in predicting outcome, compared with the ICH score.

Methods: We measured fractional anisotropy (FA) values in 5 slices below the level of the lesion on the affected and unaffected corticospinal tracts (CST) and in the cerebral peduncles (CPs) in 32 patients with supratentorial ICH who had DTI MRI within 4 days after ictus.

Background And Purpose: Distinguishing between symptoms of posterior circulation infarction (PCI) and anterior circulation infarction (ACI) can be challenging. This study evaluated the frequency of symptoms/signs in the 2 vascular territories to determine the diagnostic value of particular symptoms/signs for PCI.

Methods: Neurological deficits were reviewed and compared from 1174 consecutive patients with a diagnosis of PCI or ACI confirmed by magnetic resonance imaging in the Chengdu Stroke Registry.

Background: There is scant information on characteristics, treatment, functional outcome and case fatality of ischemic stroke with atrial fibrillation (AF) in China.

Methods: For this study, first-ever ischemic stroke patients who were admitted within 1 month of stroke onset during the period of March 2002 through December 2008 were included. Data on ischemic stroke patients were collected which included: demographics, risk factors, treatment administered, stroke-related complications and 3-month, 6-month and 1-year death and disability.

Background And Purpose: Data on the association between renal dysfunction and outcome in patients with stroke are controversial and scarce. We investigated the predictors of renal dysfunction upon admission and the association between renal dysfunction and clinical outcome in patients with acute stroke in a hospitalized Chinese population.

Methods: 1,758 acute stroke patients were consecutively enrolled into the study.

Background And Purpose: Controversy exists as to whether posterior circulation infarction (PCI) has a poorer outcome compared to anterior circulation infarction (ACI). We aimed to investigate whether PCI had different clinical outcomes from ACI in Chinese patients with ischemic stroke.

Methods: Data on ischemic stroke patients with ACI or PCI were collected including demographics, risk factors and 1-month, 3-month, and 1-year case fatality and disability (defined as modified Rankin Scale 3-5).

Objective: To investigate the association between metabolic syndrome (MS) and stroke severity in at-admission patients with acute ischemic non-embolic stroke and to study the impact of MS upon prognosis; and to assess the relative influence of each of five components of MS upon the risk of stroke severity.

Methods: The consecutive cases of ischemic stroke were prospectively registered in neurology wards from March 2006 to March 2008. Only those patients with an onset of stroke within 24 hours were included.

Background And Purpose: Women have a worse functional outcome after stroke, but the specific factors associated with a poor outcome in women are rarely reported. This study was designed to investigate the clinical predictors of 1-year disability and death in women after ischemic stroke.

Methods: Patients with ischemic stroke consecutively registered from March 2002 to July 2007 were followed prospectively for 1 year.
