Lacunar strokes, which account for about one-fifth of all strokes, occur in small arteries deep within the brain. The prevalence of LS is about 20% among all cases of ischemic stroke [ 6, 7 .A lacunar stroke, also called a lacunar infarct, occurs when an artery that supplies blood to the deeper portions of the brain becomes blocked.Lacunar lesions are associated with an abnormal deep perforating arteriole but the small size of the brain and vascular lesions make pathological .

These strokes can cause significant physical and cognitive disabilities.Treatment Approaches to Lacunar Stroke.A lacunar infarct is a tiny stroke that often causes no neurologic symptoms (these are also referred to as “silent” strokes).While cSVD has several clinical and radiographic manifestations, lacunar stroke (LS) is prototypical and accounts for 20–30% of ischemic strokes. Lacunar stroke is defined as a subcortical . 1 “Lacunar infarcts” have been thought of as strokes caused by intrinsic disease of small vessels called lipohyalinosis, resulting from hypertension 2 and diabetes. The word lacunar comes from Latin for ‘lacuna’ meaning hole, and it is used to describe a small focus of encephalomalacia containing CSF, which is the end result of liquefactive necrosis. 5 LS are particularly burdensome given a 20% .

Lesions that simultaneously interrupt pyramidal systems (weakness) and adjoining frontopontocerebellar systems (ataxia) produce ataxic . Since Fisher's early descriptions of lipohyalinosis and lacunar stroke (LS), there have been many advancements in the understanding of this disease process.
Lacunar Stroke: Symptoms, Treatments, and Long-Term Outlook
A lacunar stroke causes a small hole or space in the brain due to damaged nerve cells. Lacunes are small deep infarcts which cavitate, producing “lacunes” (French for lake). penetrating arteries originate at sharp angles from larger vessels, making them anatomically susceptible to stenosis and occlusion.We provide a broad and comprehensive overview of lacunar stroke pathophysiology both at the vessel and parenchymal levels.

According to a recent classification, lacunar infarcts are small subcortical infarcts that result from occlusion of a single perforating artery.Signs of a lacunar stroke can include: Weakness or drooping on one side of the body. Ataxia (impaired coordination) on one side of the body.Lacunar strokes are strokes caused by the occlusion of a small branch of a larger blood vessel. the term “lacune” was first .“Lacunar stroke” describes a clinical stroke syndrome with the typical symptoms and signs referable to a small subcortical or brain stem lesion.

In addition to cognitive decline and dementia, gait problems are also frequently associated with cSVD. 1 Traditionally, lacunar stroke is thought to result from disease of a small perforating artery, with typical clinical syndromes, 2 often leaving a small hole (ie, lacune) long term in the subcortical white matter. We provide a broad and comprehensive overview of lacunar stroke pathophysiology both at the vessel and parenchymal levels.Lacunar stroke is a marker of cerebral small vessel disease1 and accounts for up to 25% of ischaemic stroke.
2, 3 Clinically, LS can manifest with several syndromes depending on lesion location.A lacunar syndrome is generally the result of a small deep infarct within the territory of a single perforating artery with the maximum diameter on imaging of 15 mm. Recent studies have demonstrated alternative causes of lacunar stroke other than small-vessel disease (e. significant stenosis (> 50%) or occlusion of a relevant extra- or intracranial artery due to atherosclerosis → assessment of atherosclerotic plaques.
