Echodoppler of neck vessels
Why a Echodoppler of neck vessels:
Ultrasound imaging is a noninvasive medical test that helps physicians diagnose and treat diseases early potential and highly disabling.
The EchoDoppler of neck vessels or Doppler ultrasound of both carotid arteries, which are on each side of the neck and carry blood from the heart to the brain, provides detailed images of these blood vessels.
A Color Doppler Ultrasound study is part of a routine examination , and today , the basic and fundamental carÃ³tidas.TambiÃ©n arteries extended it to the lower limbs.
The examination of the carotid arteries is often performed to detect narrowing , or stenosis of carotid disease that substantially increases the risk of stroke (CVA / STROKE ) . Especially in patients with high cholesterol , high triglycerides , diabetes and obesity.
The main goal of this study is to look at patients obstruction or narrowing of their carotid arteries (plaques or atheromas ) which , when present , may increase the risk of STROKE . Once the diagnosis is made â€‹â€‹, you can start early preventive treatment.
It should also be performed if a patient has high blood pressure (hypertension ) or a murmur in the carotid artery, an abnormal sound in the neck that is detected by clinical examination with stethoscope in the doctor's family .
Other risk factors that require an ultrasound examination of the carotid artery are:
â–ª cholesterol and high triglycerides.
â–ª family history of stroke / STROKE or coronary disease ( unstable angina, acute myocardial infarction )
The Carotid Artery EcoDoppler also performed to :
â–ª detect early thickening of the inner layers of the carotid arteries and arteries of the lower limbs , ( prior to clinical manifestation of atherosclerosis findings) and other obstructive diseases of the vessels.
â–ª detect atherosclerotic plaques which early diagnosis radically change the strategy and intensity of the pharmacological treatment of dyslipidemia (high cholesterol) to decrease the risk of stroke.
â–ª locate a hematoma , a buildup of clotted blood that may reduce and eventually stop the blood flow.
â–ª detect carotid artery dissection , a tear between the layers of the arterial wall which can cause obstruction of blood flow, or a weakening of the wall of the artery .
â–ª monitor the status of the carotid artery after surgery to restore normal blood flow
â–ª verify the position of a stent placed to keep the blood flow of the carotid artery.
Doppler ultrasound images can help the physician to diagnose and evaluate :
â–ª narrowing of vessels (which may be caused by plaque) .
â–ª blockages to blood flow (such as clots) .
â–ª tumors or congenital malformations.
What are the benefits and risks?
â–ª Ultrasound scanning is noninvasive ( no needles or injections) and is not painful.
â–ª Ultrasound is a method that is widely available, easy to use and less expensive than other imaging methods .
â–ª Ultrasound imaging does not use ionizing radiation ( X -rays).
â–ª Ultrasound scanning gives a clear picture of soft tissues that do not show up well on x-ray images
â–ª If an examination of the carotid artery by ultrasound shows a narrowing of one or both carotid arteries , treatment can be performed to restore blood flow to the brain unobstructed . Thus many strokes are prevented.
â–ª No known harmful effects on humans to ultrasound.
â–ª In almost 50 years of experience , ultrasound of the carotid artery has been shown to be a risk -free procedure .
What are the risk factors for having a carotid disease?
They are the same as for coronary artery disease .
Diet high in fat and cholesterol.
Uncontrolled stress and anxiety.
High levels of LDL cholesterol ( bad) cholesterol and low HDL (good).
What are the symptoms of the disease Carotid arteries?
Involvement of atherosclerosis throughout the body is asymptomatic. When a person has clinical manifestation of Carotid artery disease often have what is called a transient ischemic attack . It is a sign that warns of a future stroke (CVA or Stroke) , and approximately 25 % of patients with transient cerebral ischemia develop a stroke ( CVA) in the next two years ( 1 in 4 patients , a figure nothing negligible to consider)
Symptoms of a transient cerebral ischemia are as follows:
Weakness , numbness or tingling in the middle of the body.
Disorders in the articulation of the word.
Difficulty in understanding speech.
Instability or loss of coordination (vertigo ) .
Partial loss of vision or blindness.
Â Transient cerebral ischemia can also cause a variety of visual symptoms, such as:
Abnormal eye movements .
Blurred vision .
A gray or hazy vision in the field of vision.
Anyone who has experienced these symptoms should urgently visit your doctor to know if you have had a transient cerebral ischemia and whether it is due to carotid disease.
What is the treatment for the disease Carotid arteries?
Risk factors for disease Carotid arteries are similar to those of Coronary artery disease , therefore the change of lifestyle is the same for both diseases. This includes the following :
Quit smoking, smoking is a major cause of coronary heart disease and heart failure , among men and women. The centers for prevention and control of cardiovascular diseases also suggest that the average smoker dies nearly 7 years before a nonsmoker.
Maintain a regular exercise program , the risk of not exercising has been compared to the risk of smoking a pack of cigarettes per day.
Reduce cholesterol levels . A strategy to reduce cholesterol levels is to make a heart -healthy diet that includes little fat and oils. Saturated fats raise cholesterol levels , in addition to dietary changes people are encouraged to exercise it regularly. If these strategies do not reduce cholesterol levels physician should prescribe the drugs (which have been shown to substantially reduce cholesterol levels and thus the risk of stroke and acute myocardial infarction).
Control of diabetes. People with diabetes are more likely to develop related to the arteries of the heart, brain , kidney and other diseases of the rest of the body , preventative care is crucial to maintaining health and cardiac function in diabetics.
Control of hypertension . People with high blood pressure are at increased risk or cardiovascular disease , mainly coronary heart disease. Hypertension is the most common risk factor for stroke. Hypertension can be controlled through anti hypertensive medications or making appropriate low salt diets and doing exercise daily . People should be encouraged to do regular consultations with the doctor.
Handling stress. Stress can lead to high-risk situations as much as smoking , high blood pressure and physical inactivity. In addition, chronic stress may be a direct contributor to a poor state of heart health because it causes increase in blood pressure which can become permanent.
Along with the change of lifestyle that is essential medications are prescribed to reduce the risk of stroke , these medications include daily doses of aspirin or other anticoagulants or antiplatelet drugs that prevent blood clots in the arteries.
When severe circulation of blood in the carotid artery blockages are checked invasive treatment used . Routine treatment for many years is the surgical treatment Carotid endarterectomy is , this is a treatment that is performed under general anesthesia requiring surgical incision.
In recent years it started performing angioplasty at Carotid arteries has been rapid progress in technology and at present practically equals the results of surgery. Angioplasty is a procedure that does not require general anesthesia or surgical incisions, hospitalization lasts 24 hours. has high success rate and has elective indication in specific cases necks that have been previously operated by any cause , or who have received radiation treatment or in high Carotid artery blockages that are inaccessible or more difficult in the art for the surgeon and restenosis after surgery .
Can carotid disease be prevented?
Strategies to prevent Carotid artery disease include changes in lifestyle already mentioned, and for patients at high risk of developing the disease clinicians should periodically perform color Doppler Carotid arteries as part of the screening ( check ) regular examination of patients , from age 50, or earlier if risk factors are present before we speakÂ
These studies are all covered by private insurance.
