lacunar stroke

(redirected from Lacunar Syndrome)
A condition caused by multiple minute infarcts—lacunes—in the basal ganglia, which may be seen in severe hypertension; when numerous, lacunar strokes cause dementia or a lacunar ‘syndrome’

lacunar stroke

A pathological change in the brain caused by diminished or no blood flow through one of the brain's small penetrating arteries. When this occurs, there may be no clinically detectable changes in the patient or signs and symptoms of stroke. A group of little strokes may cause progressive dementia.

As being a small vessel disease, most of the ischemic events appears in the form of subcortical infarctions causing lacunar syndrome clinically.
Dysarthria-clumsy hand syndrome is a well-known, but infrequent lacunar syndrome, which generally occurs due to a focal lesion in the basis pontis that damages corticofugal fibers, as well as adjacent pontine neurons or their axons (1,2).

Stroke etiology was classified according to the Banff classification as large-vessel disease (ipsilateral carotid stenosis [greater than or equal to] 70%, presumable local thrombosis of a large intracranial vessel, arterio-arterial embolism from aortic plaques/thrombi), small-vessel disease (clinical lacunar syndrome and no lesion or subcortical lesion <1.5 cm on computed tomography or magnetic resonance imaging), cardioembolic (high-risk source of cardiac embolism), or of undetermined etiology.

The study group comprised of 128 first-ever stroke patients, aged between 40 and 65 years, seen at either the emergency department or the neurology outpatient services, within a week after the onset of symptoms of the classic lacunar syndromes (pure motor hemiparesis, pure sensory stroke, sensorimotor stroke, ataxic hemiparesis, and dysarthria-clumsy hand syndrome), and diagnosed with stroke classed as "small-vessel" by the Trial of ORG 10172 in Acute Stroke Treatment (TOAST) classification [13].
Furthermore, small cardioembolic emboli can cause lacunar syndromes, acting as a confounding factor in the analysis of the relation between HHcy and stroke subtypes.
