Investigation on cerebral microbleeds condition of 161 patients with cerebral hemorrhage

Objective To explore associated factors of cerebral microbleeds (CMBs) in patients with intracerebral hemorrhage (ICH).Methods A total of 161 ICH patients were detected by 1.5T magnetic resonance imaging.Patients were divided into different groups according to ICH location (58 cases with lobar ICH,103 cases with non-lobar ICH).Results Eighty-eight (55％) patients hadCMBs at ICH onset,and 76 (47％) had CMBs during follow-up.Predictors of incident CMBs were ≥ 1 CMBs at ICH onset and old radiological macrohemorrhage.In the patients with nonlobar hemorrhage,CMBs was associated with lacunar state and antiplatelet drug use.In patients with lobar hemorrhage,CMBs was associated with large brain hemorrhage showed by imaging display.Conclusion The prognosis and related factors of CMBs are different according to the location of hemorrhage.
