Slightly hypoechoic plaque on the right side of the common carotid artery is caused by atherosclerotic plaque in that area.
Atherosclerotic plaques are found in large and medium-sized arteries throughout the body, such as the common carotid artery. Atherosclerotic plaque is due to hypertension, hyperlipidemia, diabetes mellitus, smoking and other factors damage to the carotid artery lining, and then a large amount of lipid deposition in the lining of the formation of plaque-like changes, with the progression of the lesion plaque calcification, which can be manifested as a slightly higher echo in the ultrasound.
In addition, if the degree of carotid artery stenosis is more serious, it may lead to insufficient blood supply to the brain, which may cause brain atrophy, mental retardation and other lesions.
Therefore, the stability of the plaque and the degree of stenosis should be evaluated by a medical professional for standardized diagnosis and treatment.
