摘要/Abstract

摘要：

增龄相关性脑小血管病谱系（spectrum o f a ge-related cerebral small vessel diseases， ArCSVDS）是指随着年龄的增长，脑小动脉、微动脉、毛细血管、微静脉、小静脉出现老化的一组脑小血管病（cerebral small vessel disease，CSVD），包括深穿支动脉病（deep perforating arteriopathy，DPA）和β淀粉样蛋白（β-amyloid，Aβ）有关的脑淀粉样血管病（cerebral amyloid angiopathy，CAA）。以往的研究往往将这两种疾病视为独立的实体，然而最近的研究发现，无论从年龄、高血压等相似的脑血管病危险因素，还是从潜在的相互作用角度出发，DPA与CAA是一组ArCSVDS疾病，血脑屏障（blood brain barrier，BBB）破坏、内皮细胞损伤、血管周围Aβ是连接DPA与CAA的共同发病机制，而且有 30%～68%的患者两者可以重叠发病。

文章导读： 随着年龄的增长，在高血压等血管危险因素的作用下，脑内β淀粉样蛋白的清除受限，临床上小动脉硬化性深穿支动脉病与脑淀粉样血管病部分重叠，应该引起临床医师的重视。

Abstract:

The spectrum of age-related cerebral small vessel diseases (ArCSVDS) is defined as a group of cerebral small vessel disease (CSVD) in which cerebral small arteries, arterioles, capillaries, venules, small veins appear ageing with age, and CSVD include deep perforating arteriopathy (DPA), β-amyloid (Aβ) related cerebral amyloid angiopathy (CAA). In the past, DPA and CAA were considered to be independent disease, while recent studies have found that they both belong to the ArCSVDS from the perspective of not only similar vascular risk factors and potential interactions, but also the mechanism. The blood brain barrier (BBB) damage, endothelial cell injury and perivascular Aβ are the common mechanism of DPA and CAA, and 30%-68% patients had both diseases.

Key words: Cerebral small vessel disease; Spectrum of age-related cerebral small vessel disease; Deep perforating arteriopathy; Cerebral amyloid angiopathy
