Lacunar stroke happens when blood flow to one of the small arterial vessels deep within the brain becomes blocked. It’s a type of ischemic stroke and accounts for about one-fifth of all strokes.

en.wikipedia.org/wiki/Lacunar_stroke

Lacunar stroke or lacunar infarct (LACI) is the most common type of ischaemic stroke, and results from the occlusion of small penetrating arteries that provide blood to the brain's deep structures. Patients who present with symptoms of a lacunar stroke, but who have not yet had diagnostic imaging performed, may be described as suffering from lacunar stroke syndrome (LACS).

medical-dictionary.thefreedictionary.com/lacunar+infarct

Any of multiple small cerebral infarcts in the corona radiata, internal capsule, striatum, thalamus, basis pontis, and/or cerebellum, occasionally preceded by transient symptoms, due to occlusion or stenosis of small penetrating branches of the middle and posterior cerebral and median branches of the basilar arteries; resolution of infarcts is characterised by residual 1–3-mm cavities or ...

Lacunar infarcts are small infarcts in the deeper parts of the brain (basal ganglia, thalamus, white matter) and in the brain stem. They are responsible for about 20 percent of all strokes. They are caused by occlusion of deep penetrating branches of major cerebral arteries and are particularly common in hypertension and diabetes, which are associated with severe atherosclerosis of small ...

An individual is said to have Lacunar Stroke Syndrome or LACS if he or she is experiencing its symptoms but has not undergone the diagnostic imaging procedures. Lacunar Infarcts involving the thalamus are known as Thalamic Lacunar Infarcts while those affecting the pons are called Pontine Lacunar Infarcts.

INTRODUCTION. Lacunar infarcts are small (0.2 to 15 mm in diameter) noncortical infarcts caused by occlusion of a single penetrating branch of a large cerebral artery [].These branches arise at acute angles from the large arteries of the circle of Willis, stem of the middle cerebral artery (MCA), or the basilar artery.

Basal ganglia lacunar infarct – this is a disruption of blood flow in the smaller arteries located in the white matter of your cerebral cortex. Some patients may experience this type of lacunar infarct one to three months after they seem to have recovered from a fungal, viral, or bacterial infection.

A lacunar stroke involves only a small area of the brain, but it can cause significant disability. Lacunar strokes account for about 20 percent of all strokes in the United States. Symptoms. The symptoms of lacunar stroke vary depending on the part of the brain that is deprived of its blood supply.

A quarter of all ischaemic strokes (a fifth of all strokes) are lacunar type.1 Lacunar infarcts are small infarcts (2–20 mm in diameter) in the deep cerebral white matter, basal ganglia, or pons, presumed to result from the occlusion of a single small perforating artery supplying the subcortical areas of the brain.2 Although a recognised stroke subtype for over 50 years, the cause of lacunar ...
