Who is at risk for lacunar infarct?
Lacunar infarct is a type of stroke that occurs when one of the arteries supplying blood to the brain gets blocked. These arteries are quite small, which makes them vulnerable to damage. While most arteries in the body gradually become smaller, the arteries of the lacunar stroke branch off a large high-pressure artery.
Basal ganglia hemorrhage is a common form of intracerebral hemorrhage, and usually as a result of poorly controlled long-standing hypertension.The stigmata of chronic hypertensive encephalopathy are often present (see cerebral microhemorrhages).. Other sites of hypertensive hemorrhages are the pons and the cerebellum. Lobar hemorrhages are also encountered but are more frequently associated ...
I63. 50 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM I63. 50 became effective on October 1, 2021.
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.
A stroke in a deep area of the brain (for example, a stroke in the thalamus, the basal ganglia or pons) is called a lacunar stroke. These deeper structures receive their blood flow through a unique set of arteries.
Lacunar infarcts are small (2 to 15 mm in diameter) noncortical infarcts caused by occlusion of a single penetrating branch of a large cerebral artery [1,2]. 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.
A lacunar stroke, also called a lacunar infarct, occurs when an artery that supplies blood to the deeper portions of the brain becomes blocked. Other types of strokes occur on the surface, or cortex, of the brain. Lacunar strokes represent anywhere from 15% to 25% of strokes.
The basal ganglia are situated at the base of the forebrain and top of the midbrain. Basal ganglia are strongly interconnected with the cerebral cortex, thalamus, and brainstem, as well as several other brain areas.
What is lacunar infarct? Lacunar stroke is a type of ischemic stroke that occurs when blood flow to one of the small arteries deep within the brain becomes blocked. A stroke occurs when a blockage interrupts or prevents blood flow to the brain.
The “basal ganglia” refers to a group of subcortical nuclei within the brain responsible primarily for motor control, as well as other roles such as motor learning, executive functions, emotional behaviours, and play an important role in reward and reinforcement, addictive behaviours and habit formation.
Current findings establish roles for the left and the right basal ganglia in word generation. Hypotheses are discussed for future research to help refine our understanding of basal ganglia functions in language generation.
Pure motor stroke (PMS), also known as pure motor hemiparesis, was first reported by Fisher and Curry in 1965 and it is considered the commonest lacunar syndrome in clinical practice, accounting for between one half and two thirds of cases, depending on the series.
A few years after infarct, there is an increased risk of death, mainly from cardiovascular causes. The risk of recurrent stroke after lacunar infarct is similar to that for most other types of stroke, and patients have an increased risk of developing cognitive decline and dementia.
Lacunar infarctions are small infarcts resulting from occlusion of deep, penetrating end arteries (see the image below). They may be caused by small vessel atherosclerosis and lipohyalinosis related to hypertension or embolic occlusion.
Some early research has indicated that lacunar infarct has a better outlook than other types of strokes. But it can still lead to an increased risk of further strokes, dementia, and death from cardiovascular causes.
What are the symptoms of basal ganglia stroke?a sudden and intense headache.numbness or weakness on one side of the face or the body.a lack of coordination or balance.difficulty speaking or understanding words spoken to you.difficulty seeing out of one or both eyes.

Code I63.8, Other cerebral infarction, was expanded and two new codes created:[& I63.81 &] Other cerebral infarction due to occlusion or stenosis of small artery I63.89 Other cerebral infarction Code I63.81 includes lacunar infarction to align with the World Health Organization’s indexing of this condition. Lacunar infarcts are small cerebral infarctions in the deep cerebral white matter, basal ganglia or pons.
