  Fact-checking   Autentic   DMCA   Report

Carotid Doppler, also known as carotid Doppler ultrasound, is an easy and painless exam that helps to evaluate the interior of the carotid arteries, which are the vessels that pass through both sides of the body and transport oxygen to the brain.

When there are health problems, such as high cholesterol or high blood pressure, there may be accumulation of fat on the wall of this artery, which reduces the flow of blood to the brain. Similarly, these small plates of grease could also rupture, forming a clot that could be transported to the brain and cause ACV.

Therefore, this exam is very used to determine the risk of developing an ACV and, in this way, to initiate the most appropriate treatment in case it is necessary, with the purpose of improving the flow of blood.



when is indicated

Carotid Doppler performance is usually indicated by the cardiologist when the person has personal or family history of high cholesterol or suffers from chronic illnesses or lifestyle habits that could favor the accumulation of fat inside the carotid artery. Therefore, this exam is indicated to evaluate the risk of ACV in persons with the following conditions:

  • Arterial hypertension;
  • Diabetes;
  • High cholesterol;
  • Family history of stroke or heart disease;
  • Coronary illness.

Apart from evaluating the risk of ACV, carotid Doppler ultrasound is also indicated to investigate atherosclerosis, aneurysms and arteritis, which corresponds to inflammation of the walls of the arteries.

How is the exam carried out

The exam is quite simple, you just need to stay in a bed while the doctor passes the ultrasound device on the sides of the skin. To improve the image of the device, it may be necessary to apply a well of gel on the skin.

If a clear image is not being obtained, the doctor can also ask you to lie on your side or change the position of the body, with the aim of improving the blood flow.



In this way, in addition to wearing comfortable clothing, it is not necessary to carry out any other type of preparation before the ultrasound.

exam results

The result of the examination must be evaluated by the doctor and, if it is considered that there is a risk of developing an ACV, some care or treatment can be recommended, such as the following:

  • Have a healthy and balanced diet;
  • Perform exercise at least 3 times a week;
  • Do not smoke and avoid places where there is humo;
  • Take medication to lower blood pressure, such as captopril or losartán;
  • Use drugs to reduce cholesterol levels, such as simvastatin or atorvastatin;
  • Taking medication to prevent plaque formation, according to medical indications, such as aspirin, for example.

Also, when one of the arteries is very closed and, for this reason, the risk of ACV is very high, the doctor can also recommend the surgery to remove the grease plate from the wall of the artery or to put a small red in it. the interior of the misma (stent) and so increase your caliber. After these surgeries, it may be necessary to repeat the carotid Doppler to ensure that the problem has resolved correctly.
