Dopplerography of the carotid arteries
Doppler examination of the cervical arteries, specifically the carotids, is a non-invasive diagnostic method used to evaluate blood flow in the carotid arteries located in the neck. This technique combines ultrasound technology with the Doppler effect to visualize blood flow and measure its velocity.
During the examination, the patient typically lies on an examination table with their head slightly tilted back. The physician uses an ultrasound probe with a gel coating on the neck area where the carotid arteries are located. The probe emits ultrasound waves into the tissues and receives reflections from the blood flowing through the arteries.
The Doppler effect is utilized to measure the velocity of blood flow. As blood moves through the arteries, its sound wave frequency changes. These changes in frequency are used to create an image of the blood flow and to measure the speed of the blood within the arteries.
The significance of this examination lies in its ability to identify and evaluate symptoms of potential issues in the carotid arteries. Narrowed or blocked carotid arteries can result in reduced blood circulation to the brain, increasing the risk of a stroke or other vascular complications. The examination can reveal the presence of plaques (atherosclerosis), blood clots, or other abnormalities in the arteries.
Early detection of these issues allows the physician to take necessary actions. Additionally, the examination can be used to monitor the arterial condition in patients with a heightened risk of vascular diseases, enabling tailored treatment plans and improved overall vascular healthcare. Experts recommend undergoing a Doppler examination of the cervical arteries and other neck vessels at least once a year, especially after the age of 50. Early diagnosis aids in preventing heart attacks and strokes.
Thus, the Doppler examination of the carotid arteries plays a crucial role in monitoring vascular issues that can significantly impact brain health and the overall vascular health status of a patient.
