How is the Examination of Vascular Ultrasonography? What Are the Plaques on It?
1. What is vascular ultrasonography?
Vascular ultrasound is an examination method that uses ultrasound to clearly display the anatomical structure of the blood vessel, the inner diameter of the lumen, and other blood vessels. Due to its simplicity, convenience, and non-invasiveness, it has become the first choice for clinical screening of vascular diseases. It can check many vascular diseases, including both arteries and veins.
Vascular ultrasound can check for the arterial stenosis,plaque and plaque nature,blood flow velocity,resistance index,also the thrombosis.

Vascular ultrasound can also check whether the vein is open, whether there is thrombosis, and whether the valve function of the vein is good.

2. What is vascular ultrasonography used for?
Vascular ultrasound can be used to examine arteries and veins. For arteries, vascular ultrasound can check the thickness of the blood vessel wall, check whether there is atherosclerosis and atherosclerosis, whether there is a plaque in the blood vessel, whether the plaque causes the stenosis or occlusion of the blood vessel lumen, the position of the plaque, as well as the flow velocity of intravascular arterial blood. These problems can be clearly displayed by ultrasound.
The venous ultrasound can check whether there is a thrombus in the blood vessel, whether the valve function in the blood vessel is intact, whether there is regurgitation, the time and degree of regurgitation, and the part of valve damage. These can be clearly answered by vascular ultrasonography of the veins. Vascular ultrasound can also detect whether the flow of the veins is normal and where the flow is faster or slower.
3. What's the matter with a plaque on vascular ultrasonography?

There are plaques on vascular ultrasonography which are mainly atherosclerotic plaque, that is, the plaque mainly occurs in the arteries. Plaques are generally divided into stable plaques and unstable plaques in professional clinical practice. The specific manifestations are as follows:
(1) Stable plaques mainly appear as strong echoes on ultrasound, that is to say, very bright plaques are seen on the image. It was called hard plaques previously, they are stable and will not fall off. They are relatively stable.
(2) Unstable plaques were previously called soft plaques, but now they are called vulnerable plaques. They have many features, including an incomplete fibrous cap, bleeding within the plaque, and neovascularization within the plaque.
The method of intra-plaque neovascularization by contrast-enhanced ultrasonography can show that if neovascularization in the plaque is found by contrast-enhanced ultrasonography, indicating instability. Then it is necessary to pay attention to check if there is a risk of stroke.
It is also necessary to remind everyone to pay attention to lowering blood lipids if there are high blood lipids, lowering blood pressure to stabilize blood pressure, and lowering blood sugar to stabilize blood sugar. It is still a conventional treatment. If the plaque is too large to cause an embolism, surgery is required.
