lacunar stroke

(redirected from Lacunar infarcts)
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.

Similar U-shaped associations were seen for hemoglobin with white matter hyperintensity volume and structural connectivity on brain MRI among individuals without dementia; these correlations were not seen with the presence of cortical or lacunar infarcts.
Acute simultaneous multiple lacunar infarcts as the initial presentation of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy.
[1] Among the ischemic strokes 50% involve the anterior circulation, 25 to the posterior circulation and the remaining 25% are lacunar infarcts. Occlusion of the MCA usually results from cardio embolism or proximal atherothrombosis.
Diffuse abnormal signals over bilateral cerebral white matters, and multiple lacunar infarcts in the right frontal and parietal lobes were observed on MRI.{Figure 1}
Diabetes mellitus is associated with lacunar infarcts, stroke, vascular dementia, and Alzheimer's disease.
Global involutional changes, bilateral old lacunar infarcts and acute infarcts at splenium of corpus callosum and deep white matter along the occipital horn of the right lateral ventricle were identified.
Magnetic resonance angiography (MRA) of the brain demonstrated the presence of multiple lacunar infarcts and inflammatory changes in the left optic nerve, consistent with optic nerve ischemia or inflammation.
There were old cortical infarcts in the right frontal and occipital lobes, with remote lacunar infarcts in the bilateral basal ganglia, thalami, and bilateral cerebellar hemispheres.
The vast majority of SBIs is small and deep and reflects penetrating artery disease, a pathogenesis shared with lacunar infarcts. Ischaemic leukoaraiosis, or white matter hyperintensities, is thought to be, together with lacunar infarction, different form of small vessel disease [24].
The consequences of CSVD on the brain parenchyma mainly show lacunar infarcts, cerebral microbleeds (CMBs), white matter lesions (WMLs), and enlarged perivascular spaces (EPVS).

Patients with clinical features suggestive of transient ischemic attack (TIA), intracranial hemorrhage, lacunar infarcts, bilateral infarcts, multiple infarcts, anterior cerebral artery territory infarcts and posterior circulation strokes were excluded from the study.
