Introduction
The standard for determining the size of carotid artery plaques on both sides is usually based on plaque thickness. Normally, the intima-media thickness of the carotid artery is less than 1 mm; a thickness between 1 and 1.2 mm is considered intimal thickening, while a thickness greater than 1.2 mm indicates plaque formation. Carotid intima-media thickness can generally be accurately assessed using color Doppler ultrasound.
The standard for assessing the size of bilateral carotid artery plaques is typically based on plaque thickness. A detailed analysis is as follows:
Carotid artery plaques are a specific manifestation of atherosclerosis in extracranial segments of the carotid and vertebral arteries, as well as other neck vessels such as the subclavian and brachiocephalic arteries. Normally, the intima-media thickness (IMT) of the carotid artery is less than 1 mm. When IMT ranges between 1 and 1.2 mm, it indicates intimal thickening, while values exceeding 1.2 mm indicate plaque formation. Carotid IMT can usually be accurately assessed using color Doppler ultrasound. These plaques most commonly occur at the bifurcation of the common carotid artery. In early stages, they are mostly asymptomatic; however, if severe stenosis develops, patients may experience symptoms such as syncope, dizziness, headache, and other discomforts.
For this condition, patients should promptly seek medical attention, complete relevant examinations to clarify the exact condition, and under medical guidance, use medications such as simvastatin tablets, pitavastatin calcium tablets, and enteric-coated aspirin tablets for treatment. Additionally, patients should maintain regular moderate exercise and a positive mood in daily life.
