Correlation between asymmetrically prominent cortical veins on susceptibility-weighted imaging and early neurological deterioration in patients with acute ischemic stroke / 国际脑血管病杂志

ABSTRACT

Objective:To investigate the correlation between asymmetrically prominent cortical veins (APCV) on susceptibility-weighted imaging (SWI) and early neurological deterioration (END) in patients with acute ischemic stroke.Methods:From October 2016 to September 2018, patients with acute ischemic stroke admitted to the Department of Neurology, Donghua Hospital Affiliated to Sun Yat-sen University were enrolled retrospectively. They completed MRI within 3 d of onset. APCV was evaluated using SWI. END was defined as the National Institutes of Health Stroke Scale (NHISS) score at any time point within 7 d after the onset increased by ≥2 or the motor function item score increased by ≥1 from baseline. Multivariate logistic regression analysis was used to determine the independent correlation between APCV and END. Results:A total of 133 patients with acute ischemic stroke were enrolled, including 40 females and 93 males, with a median age of 57.3 years (interquartile range 47.5-67.5 years). Baseline NIHSS score was 5.9±5.0. Fifty-one (38.3%) patients had APCV, and 38 (28.6%) had END. The proportions of APCV, ipsilateral large vessel stenosis, and patients receiving anticoagulation after admission were significantly different between the END group and the non-END group ( P<0.05). Multivariate logistic regression analysis showed that after adjusting for age and gender, APCV was an independent risk factor for END in patients with acute ischemic stroke (odds ratio 6.907, 95% confidence interval 2.798-17.052; P<0.001). Conclusions:APCV on SWI was an independent risk factor for END in patients with acute ischemic stroke.
