Objective To investigate the correlation of cranial MRI with renal insufficiency in elderly CVD patients, and find the risk factor of CVD. Methods 103 elderly patients with cerebrovascular disorder between April 2015 and April 2016 were identified in Guangzhou first people's hospital. Participants were grouped by the simplified MDRD equation based on eGFR levels, to confirm imaging results by detailed examination of cranial MRI. Lacunar lesions and White-matter hyperintensity were accessed and compared between renal dysfunction group and controlled group to identify the differences. Through statistical analysis, risk factors to cerebrovacular disease were considered. Results In the 103 elderly patients, the mean age of (84.23±4.92),had being divided into two groups according to eGFR< 60 ml·min^-1·1.73 m^-2:renal insufficiency group (n=52) and normal renal function group (n=51).There were statistical significance in the number of lacunar lesions,score of white-matter hyperintensity,mixed lesions between groups(P<0.05). Logistic regression analysis showed a positive correlation between age, hypertension and renal insufficiency. Conclusion ①Renal insufficiency is positively correlated with the mixed lesions and severe white-matter hyperintensity in cranial MRI,and could reflect its severity. ②Age and hypertension were risk factors for cerebral small vessel diseases.
