摘　　要：脑微出血(CMBs)是一种以微小血管破裂出血为表现的亚临床终末期微小血管病变。CMBs灶中有铁血黄素沉积,可作为顺磁性物质用于MR磁敏感序列检测微小出血灶。研究表明,CMBs增多与缺血性卒中抗血小板聚集治疗后发生脑出血有关,并证明CMBs在缺血性脑卒中治疗及预后中有一定指导作用,故笔者对CMBs在缺血性脑卒中的临床价值进行综述。Cerebral microhemorrhage(CMBs)are subclinical end-stage microvascular lesions manifested by rupture and hemorrhage of tiny blood vessels.Examination shows that CMBs foci have deposits of ferritin,which can be used as a paramagnetic substance to detect microhemorrhagic foci in MR magnetic susceptibility sequences.Studies have shown that increased CMBs are associated with cerebral hemorrhage after antiplatelet aggregation therapy in ischemic stroke,and have proved CMBs have a guiding role in ischemic stroke treatment and prognosis;therefore,the authors review the clinical value of CMBs in ischemic stroke.
