Lacunar infarction in the elderly

Lacunar infarction is a concept integrating pathology, CT and clinic. It is a common disease of the elderly. The high incidence age group is 60 ~ 70 years old. Fisher summarized it as an irregular lacuna formed after chronic healing of ischemic micro infarction (or softening focus) in deep penetrating arteries (or other micro arteries). The diameter of the micro artery involved in the lesion is about 200 µ m, and the pathological change is a lacunar or infarct of 2 ~ 20mm. The head CT scan shows a density reduction area of 2 ~ 20mm (generally no more than 15mm). At present, more than 20 kinds of lacunar syndrome can be diagnosed clinically.
