陷窝梗塞是由于小动脉闭塞所遗留下来的小腔洞,其直径从0.5～15毫米(一般为2～4毫米),好发于大脑深部(壳核37％、丘脑14％、尾状核10％),桥脑(16％)和内囊后肢(10％),少数发生于大脑深处的白质、内囊前肢和小脑。过去认为本病在生前不易诊断,主要在尸检时发现,其发现率占脑部尸检的10％,是脑血管损害中最为常见的一种类型,应引起临床工作者的重视。 The lacunar infarction is a small cavity left by small arterial occlusion and its diameter is from 0.5 to 15 mm (usually 2 to 4 mm) and occurs in the deep part of the brain (37% in the putamen, 14% in the thalamus, and the caudate nucleus 10%), pontine (16%) and posterior limbs (10%), a few occur in the brain of the white matter, the forelimb of the internal capsule and the cerebellum. In the past that the disease is difficult to diagnose in life, mainly found at the autopsy, the discovery rate of 10% of brain autopsy, is the most common type of cerebrovascular damage, should arouse the attention of clinicians.
