Abstract:
Objective To concentrate on the morbidity of cerebral microbleed (CMB) in patients with hypertension and to analyze the predilection and risk-factor of cerebral microbleed.Method Hypertensive patients were divided into the simple hypertention group, hypertention group with lacunar infarction and hypertention group with cerebral infarction.All of these 65 patients received examination of susceptibility-weighted imaging.Results Ninety-one focuses of cerebral microbleeds were found in these patients:58.2% of these focuses were in both basal ganglia and cerebral ganglion;35.2 percent were in cortex and subcortex;6.6 percent were in brainstem and cerebellum.The total morbidity of CMB was 33.8 percent, 52.4 percent in the group with lacunar infarction and 38.1 percent in the group with cerebral infarction, both were significantly higher than that of 8.7 percent in the simple hypertensive group (χ2= 8.08,P<0.01 andχ2=3.86, P<0.05).Conclusions The focus of CMB suggested the hemorrhagic tendency in endocranial capillary.CMB can be used as a routine exam for the hemorrhagic tendency in endocranial capillary.Synthetic analysis of risk-factor and the result of SWI help clinicians choose suitable treatment for each patient.
