senile lacunar infarction

Lacunar infarction is a common disease in the elderly, with a high incidence age group of 60-70 years. Its overview is: ischemic microinfarction (or softening foci) occurring in deep penetrating arteries of the brain (or other small arteries), forming irregular lacunae after chronic healing. The diameter of the small arteries involved is about 200 μm, and the pathological changes are lacunae or infarct foci of 2-20 mm. Cranial CT scanning shows areas of reduced density of varying degrees of 2-20 mm (generally not exceeding 15 mm). Currently, more than 20 types of lacunar syndromes can be diagnosed clinically.
