摘要
颅内动脉扩张延长症亦称扩张性脑动脉病，表现为至少1支颅内动脉长度和直径增加，受累的颅内动脉扩张延长。脑小血管病主要指脑内小血管病变导致的疾病，通常用于描述脑白质和皮质下灰质的一系列影像学改变，包括近期皮质下小梗死、腔隙、白质高信号、血管周围间隙扩大、脑微出血和脑萎缩。最近越来越多的研究显示颅内动脉扩张延长症与脑小血管病存在一定联系。
Intracranial arterial dolichoectasia, also known as dilated cerebral artery disease, is characterized by an increase in the length and diameter of at least one intracranial artery, and the involved intracranial arteries enlarge and dilate. Cerebral small vessel disease mainly refers to diseases caused by small vessel lesions in the brain. It is usually used to describe a series of imaging changes of white matter and subcortical gray matter, including recent subcortical small infarction, lacuna, white matter hyperintensity, enlarged perivascular space, cerebral microhemorrhage, and cerebral atrophy. Recently, more and more studies have shown that there is a certain correlation between intracranial arterial dolichoectasia and cerebral small vessel diseases.
