carotid ultrasound

Carotid ultrasound is an auxiliary test for checking the normality of arteries. 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 trials. The corresponding symptoms can be judged by the above instrument examination. Basic Information Specialist classification: growth and development check classification: ultrasound Applicable gender: whether men and women apply fasting: fasting Tips: Do not exercise vigorously before the examination, and remove the neck ornaments. Normal value Intravascular medial no thickening, no plaque formation, no vascular stenosis, no occlusion. Clinical significance Abnormal results: Carotid artery color Doppler 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, the degree of stenosis and stenosis, the presence or absence of occlusion, etc. Accurate measurement and localization can also be used to analyze hemodynamic outcomes of arteries. In particular, it can detect the presence of early carotid atherosclerotic lesions, so that patients can be promptly prevented and treated. The timely diagnosis of moderate to severe carotid stenosis and occlusion can be used as a strong basis for clinical treatment of carotid endarterectomy. People who need to be examined: patients with cardiovascular disease. Precautions Before the examination: Generally, no special preparation is required before the carotid ultrasound examination, as long as the neck accessories that will affect the examination are removed before the examination. If you have just finished strenuous exercise, you need to rest for 5 to 10 minutes, and then check if your breathing and heart rate are relatively stable. Requirements for examination: The patient actively cooperates with the doctor to check, prepares according to the doctor's requirements, and the doctor carefully operates. Inspection process When examined, patients generally do not feel uncomfortable. In pulsed Doppler ultrasonography, the ultrasonic instrument emits a "click" sound, which is the Doppler shift signal generated when the blood flows. Through this sound, the doctor can determine whether the blood vessel is sick or not. Don't be too nervous. The entire inspection process takes only ten minutes. Not suitable for the crowd Nothing is suitable for the crowd. Adverse reactions and risks No complications.
