Abstract:
Objective To investigate the incidence,distribution patterns,and influencing factors of cerebral microbleed (CMB) in Chinese adult patients with moyamoya disease.Methods Thirty consecutive patients with moyamoya disease confirmed by digital subtraction angiography from the Nanking Stroke Registry Program were included.All patients performed conventional MRI sequences (3.0 T) and susceptibility-weighted imaging.The clinical data,such as medical history,systolic blood pressure,diastolic blood pressure,mean arterial pressure,and white matter lesions were collected.Their fasting blood glucose levels and fibrinogen levels were detected.The numbers of CMB lesion,distribution information,and their relationship with various clinical parameters in patients with moyamoya disease were analyzed.Results Among the 30 subjects included,14 CMBs were detected in 10 patients from 11 hemispheres.The distribution of the lesions was mainly in deep brains (71.4%),especially in the periventricular white matter (50.0%).There was no statistical difference in age,gender,hemorrhage symptoms,blood pressure,white mater lesions,and plasma fibrinogen levels between the CMB positive group and CMB negative group.However,the fasting blood glucose levels in the former was significantly higher than those in the latter (8.0 ± 4.1 mmol/Lvs.4.8 ± 0.4 mmol/L;P =0.035).Multivariate regression analysis showed that the increased fasting blood glucose level was an independent risk factor for the occurrence of CMBs in adult patients with moyamoya disease (OR = 10.992,95% CI 1.325-91.218;P=0.026).Conclusions The CMB lesions are susceptible to Chinese adult patients with moyamoya disease in deep brains,especially in the periventricular white matter.The fasting blood glucose level may influence the incidence of CMBs in patients with moyamoya disease.
