腔隙性脑梗塞亦称微梗塞或腔隙性脑卒中,是指位于大脑半球深部白质和脑干的小软化灶,直径为3～4mm,最大直径可达20mm。腔隙性脑梗塞首先由Fisher于1956年提出,并报告了20余种不同的腔隙综合征,还对其临床表现做了详尽的描述。腔隙性脑梗塞与临床上经常遇到的脑动脉粥样硬化性脑血栓形成两者在病因、病理及临床表现等方面均有不同,在CT问世以前只是病理诊断,我们常将此病诊断为脑血栓形成或脑供血不足。CT的应用使绝大多数腔隙性脑梗塞患者得到及时确诊与治疗。我科自1986～ Lacunar infarction, also known as micro-infarct or lacunar stroke, refers to a small softening lesion located in the deep white matter and brainstem of the hemisphere, with a diameter of 3 to 4 mm and a maximum diameter of up to 20 mm. Lacunar infarction was first proposed by Fisher in 1956 and reported more than 20 different lacunar syndromes, as well as an exhaustive description of its clinical manifestations. Lacunar infarction and clinical often encountered cerebral atherothrombosis both in the etiology, pathology and clinical manifestations of both have different in the advent of CT before the pathological diagnosis, we often diagnose the disease Cerebral thrombosis or cerebral insufficiency. CT application to the vast majority of patients with lacunar infarction timely diagnosis and treatment. My department since 1986 ~
