Lipohyalinosis - Wikipedia
Lipohyalinosis is a cerebral small vessel disease affecting the small arteries, arterioles or capillaries in the brain. Originally defined by C. Miller Fisher as 'segmental arteriolar wall disorganisation', it is characterized by vessel wall thickening and a …
Lipohyalinosis - an overview | ScienceDirect Topics
Lipohyalinosis is a degenerative disease in which lipids and hyaline form in the vessel wall to block blood flow. Lacunar infarction may also be caused by microatheroma that obstructs the orifice of a small penetrating artery at its origin from the large parent artery.
Lacunar Stroke - StatPearls - NCBI Bookshelf
2024年3月10日 · Small arterial occlusion is the fundamental pathogenesis for lacunar strokes. The primary underlying pathophysiological processes are lipohyalinosis and microatheroma formation. In lipohyalinosis, the media of small vessels thickens, followed by fibrinoid deposition and hypertrophy of smooth muscle and other connective tissue elements.
Lacunar stroke: mechanisms and therapeutic implications
Lipohyalinosis is defined as concentric hyaline thickening of the cerebral small vessels leading to occlusion of the small penetrating arteries 13 and is one of the first and most common lacunar stroke mechanisms described and pathologically proven to cause lacunar stroke. 14 Lipohyalinosis is thought to originate from hypertension-related hyper...
Pathophysiology of Lacunar Stroke: History's Mysteries and …
Herein, we review lipohyalinosis as it relates to modern concepts of cerebral small vessel disease (cSVD). We discuss clinical classifications of LS as well as radiographic definitions based on modern neuroimaging techniques.

2023年11月29日 · Lipohyalinosis was identified by Fisher 5,46 as the causal lesion upstream from 40 of 50 lacunes, in brains from 4 people with severe hypertension. Lipohyalinosis describes small arteries whose walls exhibited loss of myocytes, fibrosis, and fatty macrophages with lipid deposits 5 ( Figure 2C ).

2024年2月29日 · Other lacunar strokes are caused by a thickening of the deep-brain blood vessels, a condition known as lipohyalinosis. Again, this makes blockages more likely by leaving less space for blood to...
Lacunar Infarction and Small Vessel Disease: Pathology and ...
Intrinsic disease of a penetrator (lipohyalinosis, CAA, CADASIL or other occlusive diseases within the course of the penetrating artery) causes a small infarct in the center of the penetrating artery supply.

2020年9月24日 · lipohyalinosis (lī-pō-hī′ă-lĭn-ō″sĭs) Degenerative changes in small blood vessels, marked by the accumulation of a glassy- or waxy-appearing lipid within the vessel wall. This type of vascular degeneration occurs in hypertension and atherosclerosis, and predisposes patients to small infarcts, esp. in penetrating arteries of the brain.

2020年9月8日 · Lipohyalinosis (also known as fibrinoid necrosis) is a disease affecting the small cerebral arteries associated with lacunar infarction and deep white matter changes related to small vessel chronic ischaemia.
