The maximum plaque thickness in the right carotid artery is 3.5mm, and it is multiple mixed plaques, which is more serious and requires attention and timely medical treatment. The size and typing of arterial plaques are closely related to the occurrence of cerebral infarction.
1. Size: Plaque size reflects the degree of carotid artery stenosis to a certain extent, and ultrasound can be used to detect the carotid artery intima-media thickness (IMT) to determine whether there is atherosclerotic plaque formation.
Normal IMT should be less than 1.0mm, greater than 1.2mm for plaque formation. 3.5mm plaque is a more serious plaque, there is obvious carotid artery stenosis, will cause the occurrence of ischemic stroke in the elderly, and need to pay special attention.
2. Typing: Carotid plaques are divided into hard plaques, soft plaques and mixed plaques. Hard plaque is more common, relatively stable and not easy to rupture. Soft plaque is the most dangerous type, which is prone to rupture and can lead to serious diseases such as cerebral embolism after falling off. Mixed plaques are in between soft and hard plaques, unstable and prone to rupture and thrombosis.
It is recommended that patients with carotid plaques seek medical attention in a timely manner and be treated actively under the guidance of a doctor to avoid delays in their condition.
