Lacunar stroke or lacunar cerebral infarct (LACI) is the most common type of ischemic stroke, resulting from the occlusion of small penetrating arteries that provide blood to the brain's deep structures.

2024年3月10日 · Lacunar stroke is a prevalent type of ischemic stroke that contributes significantly to morbidity and mortality worldwide. Participants will explore its distinct risk factors, clinical presentations, and management options, emphasizing the crucial role of an interprofessional team in delivering comprehensive care.

2023年7月27日 · In a lacunar stroke, brain cells in a relatively small area (measuring from 3 millimeters to as much as 2 centimeters across) are damaged or killed by lack of oxygen. Such a small area of brain destruction is called a lacune. A lacunar stroke involves only a small area of the brain, but it can cause significant disability.

2025年1月20日 · Symptomatic patients may present with lacunar stroke syndrome, one of five distinct syndromes. Lacunar infarcts, by definition, are caused by occlusion of small penetrating end-arteries and must be smaller than 15 mm. They are mostly thought to result from in situ microatheroma formation or lipohyalinosis 2.

2024年11月25日 · Lacunar strokes happen when a blood clot blocks a small blood vessel deep in your brain. Call for help immediately if you think you’re experiencing any stroke symptoms. Getting treatment as soon as possible is the best way …

We discuss clinical classifications of lacunar stroke as well as radiologic definitions based on modern neuroimaging techniques. We provide a broad and comprehensive overview of lacunar stroke pathophysiology both at the vessel and parenchymal levels.

About 20% of all strokes (about 25% of all ischemic stroke) are lacunar in type (57). These small lesions (<2 cm in diameter, <1.5 cm in some definitions) affect the white matter and deep gray matter of the cerebral hemispheres and brainstem and are associated with several discrete neurological syndromes 4, 25, 26.

Lacuna stroke are caused by Cerebral small vessel disease (cSVD) a term used for different pathological processes that affect the small vessels of the brain. cSVD has a crucial role in lacunar cerebral infarction and deep or cortical haemorrhages. In addition to cognitive decline and dementia, gait problems are also frequently associated with cSVD.

Lacunar infarcts represent a series of small perforating vessel occlusions that result in clinical symptoms that differ from large artery infarctions. Lacunar strokes tend to be either motor or sensory and typically lack cortical findings such as alterations of consciousness or corticosensory modalities (i.e., graphesthesia, stereognosis).

2022年12月2日 · lacunar stroke (lacunar cerebral infarct – LACI) is defined as a small subcortical lesion ≤ 1.5 cm in diameter, resulting from the occlusion of small penetrating arteries
