What Is a Carotid Artery Ultrasound?

There was no thickening of the medial lining of the blood vessel, no plaque formation, no stenosis of the blood vessel, and no occlusion.

Carotid color Doppler ultrasound is an auxiliary test used to check whether the arterial blood vessels are normal. Carotid ultrasound is one of the effective methods for diagnosing and evaluating carotid wall lesions. It plays a key role in the epidemiological investigation of atherosclerosis and the evaluation of the effectiveness of atherosclerosis prevention and treatment tests. The corresponding symptoms can be judged by the above-mentioned instrument inspection.

Name: Carotid color Doppler ultrasound

category: Ultrasound (B ultrasound, A ultrasound)

Carotid color Doppler ultrasound normal

There was no thickening of the medial lining of the blood vessel, no plaque formation, no stenosis of the blood vessel, and no occlusion.

Clinical Significance of Carotid Color Doppler Ultrasound

Abnormal results: Carotid color Doppler ultrasound can not only clearly show whether the intima of the blood vessel is thickened, whether there is plaque formation, the location of plaque formation, the size, whether there is vascular stenosis and the degree of stenosis, whether there is occlusion, etc. Accurate measurement and positioning can also analyze the hemodynamic results of the detected arteries. In particular, the presence of early carotid atherosclerotic lesions can be detected so that patients can be promptly prevented and treated; timely diagnosis of moderate to severe carotid stenosis and occlusion can be used as a strong basis for clinical carotid endarterectomy. People to be checked: Patients with cardiovascular disease.

Precautions for carotid color Doppler ultrasound examination

Before the examination: Carotid arterial ultrasound is generally not required to prepare before the examination, as long as the neck decorations that will affect the examination can be removed before the examination. If you have just done strenuous exercise, you need to rest for 5-10 minutes, and then check after breathing and heart rate are relatively stable. Requirements during the examination: The patient actively cooperates with the doctor for examination, prepares according to the requirements of the doctor, and the doctor operates carefully.

Carotid color Doppler ultrasound examination process

During the examination, patients generally do not feel uncomfortable. During pulse Doppler ultrasound examination, the ultrasonic instrument will emit a "whine" sound, which is a Doppler frequency shift signal generated when the blood is flowing. Through this sound, the doctor can determine whether the blood vessel is diseased Don't be overly nervous. The entire inspection process takes only ten minutes.
