Background: Growing data indicate a higher prevalence of cerebrovascular diseases in patients with ESRD. Cerebral small-vessel disease (CSVD) is an important risk factor of stroke and dementia. A comprehensive assessment of CSVD in a dialysis population is needed. Methods: In this retrospective cross-sectional study, we enrolled 179 dialysis patients and 351 controls matched by sex and age with normal serum creatinine. The presence and locations of 3 main features of CSVD in dialysis patients, including lacunes, cerebral microbleeds (CMBs), and white matter hyperintensities (WMHs), were evaluated with brain magnetic resonance imaging and compared with controls. Univariate and multivariate analyses were performed to identify risk factors. Results: Compared with controls, the prevalence of CSVD was significantly increased in dialysis patients (odds ratio [OR] 2.66, 95% confidence interval [CI] 1.26–5.62). Among them, risks of CMBs and WMHs were increased in dialysis (OR 4.01, 95% CI 1.78–9.42; 3.91, 95% CI 1.67–9.15), except for lacunes. The age of subjects with CSVD detected was significantly younger in the dialysis group (p = 0.002). Unlike controls, basal ganglia were most affected by lacunes and CMBs in dialysis patients. In dialysis patients, multivariate analysis further revealed that aging, smoking, and hyperlipidemia were significantly associated with CSVD, while dialysis modality was not significant. Conclusion: We demonstrated a higher prevalence and early-onset tendency of CSVD in dialysis patients, especially for CMBs and WMHs. Dialysis patients showed different patterns and associated factors for CSVD.
