While most A stroke occurs when blood flow to the brain is interrupted or blocked. Strokes that are caused by blockages in blood vessels within the brain are called ischemic strokes. Lacunar stroke is a type Lacunar infarcts are small (<15 mm) infarcts in the distal distribution of deep penetrating vessels (lenticulostriate, thalamoperforating, and pontine perforating arteries, recurrent artery of Heubner). They result from occlusion of one of the small penetrating end arteries at the base of the brain and are due to fibrinoid degeneration. A lacunar stroke occurs when one of the arteries that provide blood to the brain's deep structures is blocked. These arteries are small, and are uniquely vulnerable. Unlike most arteries, which gradually taper to a smaller size, the small arteries of a lacunar stroke branch directly off of a large, high-pressure, heavily muscled main artery.

An infarct is any tissue that has died because of not receiving oxygen normally caused by some problem with the flow of blood.

This is the most common (33-50%) lacunar syndrome and usually occurs with infarction of the posterior limb of the internal capsule, which carries the descending corticospinal and corticobulbar tracts, or the basis pontis. It is characterized by contralateral hemiparesis that typically affects the face, arm, or leg in approximately equal measure. Lacunar Infarct (LACI) is a kind of stroke that affects the brain of an individual.

Försämring av neurologiska symtom (medvetande, pares, språk) de första 2-3 dagarna, förekommer hos cirka 20-40% av patienterna. Patienter med diabetes, högt blodtryck och tidigare lakunär infarkt verkar vara ha en särskilt hög risk. Rutinmässig användning av NIHSS kan hjälpa till att upptäcka försämringar i ett tidigt skede. Als lakunäre Infarkte bezeichnet man kleinere Hirninfarkte (≤ 1,5 cm Durchmesser), die in der Regel durch mikroangiopathische Veränderungen entstehen.

It is characterized by contralateral hemiparesis that typically affects the face, arm, or leg in approximately equal measure. Lacunar strokes are strokes caused by the occlusion of a small branch of a larger blood vessel. Because of the way blood vessels divide in the brain, lacunar strokes tend to occur in areas located in the deeper parts of the brain, where many of the smaller blood vessel branches are located. 1 Lacunar Infarct Images It is a form of stroke which occurs due to the blockage of a penetrating artery that controls the blood supply to the deep structures of the brain. 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 strokes often arise from chronic high blood pressure, which leads to progressive narrowing and finally blockage of small arteries that supply deep brain structures.

En embolisk infarkt utgörs av att en blodpropp lossnat från bildningsstället. En trombotisk hjärninfarkt orsakas av en blodpropp bildad i ett kärl. Lakunär infarkt omfattar ett relativt litet område i hjärnan som efter några veckor omvandlas till vätskefyllda hålrum. hos patienter med hemorragisk stroke eller lakunär infarkt i anamnesen vid studiestart.
