Lacunar Infarcts

Lacunar infarcts are small infarcts in the deeper parts of the brain (basal ganglia, thalamus, white matter) and in the brain stem.
Lacunar infarcts are caused by occlusion of a single deep penetrating artery.
Lacunar infarcts account for 25% of all ischemic strokes.
Atherosclerosis is the most common cause of lacunar infarcts followed by emboli.
25% of patients with clinical and radiologically defined lacunes had a potential cardiac cause for their strokes.
