Objective:To investigate the relationship between the overall burden score of cerebral small vessel disease (CSVD) and sudden sensorineural hearing loss (SSNHL) and its severity.Methods:Patients with SSNHL admitted to Zhengzhou People’s Hospital from January 2019 to June 2022 were used as the case group, and age- and gender-matched patients with tension headache or benign positional vertigo were used as the control group. MRI was used to evaluate the phenotype of CSVD, including white matter hyperintensities (WMHs), cerebral microbleeds (CMBs), enlarged perivascular spaces (EPVS), and lacune of presumed vascular origin, and then the total burden score of CSVD was calculated. Multivariate logistic regression analysis was used to determine the independent factors of SSNHL. Ordinal logistic regression analysis was used to investigate the relationship between the overall burden of CSVD and the severity of hearing loss in patients with SSNHL. Results:A total of 86 patients with SSNHL and 90 age- and gender-matched controls were included. There were statistically significant differences in triglycerides, high-density lipoprotein cholesterol, fasting blood glucose levels, WMHs overall score classification, periventricular WMHs score classification, deep WMHs score classification, CMBs, moderate to severe EPVS, CSVD overall burden score and classification between the two groups (all P<0.05). Multivariate logistic regression analysis showed that after adjusting for high-density lipoprotein cholesterol, fasting blood glucose ≥6.1 mmol/L (odds ratio [ OR] 2.149, 95% confidence interval [ CI] 1.042-4.432; P=0.038), triglycerides ≥1.7 mmol/L ( OR 7.012, 95% CI 2.962-16.597; P=0.000), CSVD overall burden score >1 (compared to 0 point, 2 points: OR 4.095, 95% CI 1.364-12.291, P=0.012; 3 points: OR 5.776, 95% CI 1.888-17.614, P=0.002; 4 points: OR 7.900, 95% CI 2.526-24.706; P=0.000) were significantly independently correlated with SSNHL. Ordinal logistic regression analysis showed that after adjusting for age and fasting blood glucose, the flat decline type hearing loss ( OR 1.276, 95% CI 1.131-1.618; P=0.044) and total deafness type hearing loss ( OR 1.029, 95% CI 1.002-1.058; P=0.038), and the overall burden of CSVD being moderate ( OR 1.318, 95% CI 1.036-1.677; P=0.025) and severe ( OR 2.330, 95% CI 1.232-4.406; P=0.009) were significantly independent associated with the degree of hearing loss in patients with SSNHL. Conclusion:The CSVD total burden score of moderate to severe degree is independently associated with SSNHL and the degree of hearing loss.

Objective:To investigate the correlation between white matter hyperintensities (WMHs) and collateral circulation in patients with stroke caused by anterior circulation large vessel occlusion (aLVO).Methods:Patients with stroke caused by aLVO treated with endovascular mechanical thrombectomy in the Department of Neurology, Zhengzhou People's Hospital from December 2017 to April 2021 were retrospectively enrolled. Their demography, vascular risk factors, baseline clinical data and Fazekas scale score were collected. Multivariate logistic regression analysis was used to determine the independent correlation between WMHs and the collateral circulation status in patients with aLVO. Results:During the study, 166 patients with aLVO were included (77 males, 46.39%; aged 69.62±5.91 years). Their baseline National Institutes of Health Stroke Scale (NIHSS) score was 9.33±4.42. There were 120 patients (72.29%) in the good collateral circulation group and 46 (27.71%) in the poor collateral circulation group. Univariate analysis showed that there were significant differences in baseline NIHSS score, total Fazekas score and periventricular Fazekas score between the good collateral circulation group and the poor collateral circulation group (all P<0.05). Multivariate logistic regression analysis showed that total Fazekas score (odds ratio 2.583, 95% confidence interval 1.445-4.619; P=0.001) and periventricular Fazekas score (odds ratio 2.190, 95% confidence interval 1.022-4.692; P=0.044) were the independent risk factors for the poor collateral circulation. Conclusion:The severity of WMHs is associated with the poor collateral circulation in patients with aLVO.

Objective To investigate the difference in collateral circulation and clinical prognosis between cervical carotid atherosclerosis and cardioembolism.Methods We enrolled 318 adult endovascular patients with acute ischemic stroke due to anterior circulation occlusion between January 2014 and November 2020.132 patients with cervical carotid atherosclerosis and 186 with cardioembolism were included.The collateral score,the modified Rankin Scale (mRS) score,mortality at 90 days between patients with carotid artery stenosis and patients with cardiogenic embolism was compared.Results Compared with stroke due to cardiac embolism,stroke due to carotid atherosclerosis had a higher incidence of the internal carotid artery end occlusion(P<0.001)and a higher collateral-circulation score(OR=1.63),a lower mRS scores before stroke(P<0.001),and a lower 90-day median MRS score(OR=1.93).Conclusion Compared with cardiogenic embolic stroke patients,carotid atherosclerotic stroke patients have better collateral circulation and slightly better median MRS at 90 days.
