Broad category of disorders of blood flow in the arteries and veins which supply the brain; includes cerebral infarction, brain ischemia, brain hypoxia, intracranial embolism and thrombosis, intracranial arteriovenous malformations, etc; not limited to conditions that affect the cerebrum, but refers to vascular disorders of the entire brain. ...

What are the two components of the cerebral small vessels?

Cerebral small vessels comprise two components. First, the leptomeninges vasoganglion, which is derived from subarachnoid space covering, and the convex surface of brain. Second, perforating arteries are derived from anterior, middle, posterior cerebral arteries that supply the subcortical parenchyma (Fig. 1). The cerebral small vessels are crucial to maintenance of adequate blood flow to the sub-surface brain structure. They include small arteries, arterioles, venules, and capillaries which are commonly sized at 50–400 µm1,2.

What is occlusive vessel lumen?

Occlusion of the vessel lumen is represented and acute ischemia due to decreased flow in the vessel occurred.

What are the pathologic changes associated with CSVD?

Among the pathologic changes involved in CSVD, the two most common are arteriolosclerosis and cerebral small vascular atherosclerosis. Arteriolosclerosis, a vascular risk-factor-related SVD, is known to be age-related, and is the most common small vessel alteration in aged brains. The severity of arteriolosclerosis increases with aging and is exacerbated by hypertension and diabetes (Fig. 2)5. Thus, arteriolosclerosis is also named hypertensive SVD6. Cerebral small vascular atherosclerosis, particularly in arterioles smaller than 50 µm in diameter, is characterized by a loss of smooth muscle cells from the tunica media, degeneration of internal elastic lamina, proliferation of fibroblasts (Fig. 2), deposits of fibro-hyaline material and collagens, thickening of the vessel wall, formation of microatheroma, and narrowing of the lumen1. With these changes, the vessels become elongated, tortuous and inflexible (Fig. 2). In addition, wall damage causes distension of its outer portions due to fibrosis, that is microaneurysm, and the stenosis or obstruction of proximal lumen7. Ultimately, impaired autoregulation of involved small vessel results in reduced cerebral blood flow (CBF) and chronic cerebral hypoperfusion6. The occlusion of arterial lumen leads to acute ischemia, causing lacunar infarction (Figs. 2and ​and3).3). Whereas, critical stenosis and hypoperfusion involving multiple small arterioles, mainly in deep white matter, lead to incomplete ischemia which are visualized as White Matter Hyperintensities (WMH) on neuroimaging8. The two pathophysiological pathways above can often overlap, so lacunes and white matter lesions often coexist in the same patient. Kuwabara and colleagues found a 25% decreases in CBF in patients with both Alzheimer’s and Binswanger’s diseases, with the use of positron emission tomography with oxygen-15-labelled water9. Conventional risk factors such as hypertension diabetes, smoking, high homocysteine concentrations, obesity, and dyslipidemia have been considered to lead to arteriolosclerosis. In addition, hematological disorders, infection, and hereditary diseases are increasingly recognized in various studies10,11.

What is CSVD in neurology?

Cerebral small vessel disease (CSVD) is a generic term that refers to intracranial vascular disease based on various pathological and neurological processes, as well as a syndrome referring to different clinical manifestations and neuroimaging features caused by the structural changes of vascular and brain parenchyma. Small vessel disease accounts for up to 25% of all ischemic strokes3but also put patients at twice the risk for these conditions4. In addition, CSVD is a leading cause of functional loss, disability and cognitive decline in the elderly. Neuroimaging development allows increased understanding of CSVD. Thus, a comprehensive knowledge of its pathophysiologic mechanism, neuroimaging, and clinical features is imperative to further study on possible preventive and therapeutic measures.

What is CSVD in the brain?

Cerebral small vessel disease (CSVD) is composed of several diseases affecting the small arteries, arterioles, venules , and capillaries of the brain, and refers to several pathological processes and etiologies. Neuroimaging features of CSVD include recent small subcortical infarcts, lacunes, white matter hyperintensities, perivascular spaces, microbleeds, and brain atrophy. The main clinical manifestations of CSVD include stroke, cognitive decline, dementia, psychiatric disorders, abnormal gait, and urinary incontinence. Currently, there are no specific preventive or therapeutic measures to improve this condition. In this review, we will discuss the pathophysiology, clinical aspects, neuroimaging, progress of research to treat and prevent CSVD and current treatment of this disease.

What are the pathophysiologic mechanisms of CSVD?

The European small brain vascular disease expert group puts forward the classification of CSVD based on cerebrovascular pathologic changes as the following: Arteriolosclerosis, sporadic and hereditary cerebral amyloid angiopathy, inherited or genetic small vessel diseases distinct from cerebral amyloid angiopathy, inflammatory and immunologically-mediated small vessel diseases, venous collagenosis, and other small vessel diseases such as post-radiation angiopathy1. These various pathologic changes cited by the European expert group do not only result in damage of brain parenchyma including neuronal apoptosis, diffuse axonal injury, demyelination and loss of oligodendrocytes, but also result in a series of symptoms and unusual neuroimaging findings.

What causes cerebral vascular dysfunction?

Long-term and chronic oxidative stress in aging, and hypertension lead to cerebral vascular dysfunction including impaired neurovascular coupling, inward remodeling, rarefaction, and BBB disruption, which result in brain injury and cognitive dysfunction (Fig. 4)31. In the inherited or genetic SVDs such as Fabry’s disease and CADASIL32,33, there is still a controversy about the mechanisms of brain injury. Moore and colleagues reported that the deposition of globotriaosylceramide (Gb3) leads to altered vascular reactivity, resulting in increased blood flow and metabolic vulnerability in the deep white matter. These findings are contrary to chronic cerebral hypoperfusion found in other studies34–36.

What is small vessel disease?

Small vessel disease. Small vessel disease. Clogging or narrowing of the arteries that supply blood to your heart can occur not only in your heart's largest arteries (the coronary arteries) but also in your heart's smaller blood vessels. Small vessel disease is a condition in which the walls of the small arteries in the heart are damaged.

Why is small vessel disease so serious?

Because small vessel disease can make it harder for the heart to pump blood to the rest of the body, the condition, if untreated, can cause serious problems, such as:

What is the condition where the walls of the small arteries in the heart aren't working properly?

Small vessel disease is a condition in which the walls of the small arteries in the heart aren't working properly. This reduces the flow of oxygen-rich blood to the heart, causing chest pain (angina), shortness of breath, and other signs and symptoms of heart disease.

Is small vessel disease more common in women?

Small vessel disease is more common in women and in people who have diabetes or high blood pressure.

Is small vessel disease treatable?

Small vessel disease is treatable but may be difficult to detect. The condition is typically diagnosed after a health care provider finds little or no narrowing in the main arteries of the heart despite the presence of symptoms that suggest heart disease.

What is the diagnosis of MVD?

Your doctor or other health care professional will diagnose coronary MVD based on your medical history, a physical exam and test results. You will also be evaluated for any risk factors for heart disease including high cholesterol, metabolic syndrome, diabetes and being overweight or obese.

Can atherosclerosis cause MVD?

Many researchers think some of the risk factors that cause atherosclerosis may also lead to corona ry MVD. Atherosclerosis is a disease in which plaque builds up inside the arteries.

Can low estrogen cause microvascular disease?

Understand your risk for coronary microvascular disease. Women may be at risk for coronary MVD if they have lower than normal estrogen levels at any point in their adult lives. Low estrogen levels before menopause can raise younger women's risk for coronary MVD and can be caused by stress and a functioning problem with the ovaries.

Does MVD cause spasms?

In coronary MVD, the heart's coronary artery blood vessels don't have plaque, but damage to the inner walls of the blood vessels can lead to spasms and decrease blood flow to the heart muscle. In addition, abnormalities in smaller arteries that branch off of the main coronary arteries may also contribute to coronary MVD.

Can CHD be detected with MVD?

Standard tests for CHD may not be able to detect coronary MVD. These tests look for blockages in the large coronary arteries. Coronary MVD affects the tiny coronary arteries. If you have angina but tests show your coronary arteries are normal, you could still have coronary MVD.
