Q:
What is lacunar infarct?

A:
Lacunar stroke or lacunar infarct (LACI) is the most common type of ischemic stroke. It results from the occlusion of small penetrating arteries. A stroke occurs when blood flow to the brain is interrupted or blocked. According to the National Institutes of Health (NIH), lacunar strokes represent about one-fifth of all strokes. Any type of stroke is dangerous because brain cells are deprived of oxygen and begin to die within minutes.
