What is Subclavian Artery Stenosis?
Subclavian artery stenosis is a condition where the main artery that supplies blood to your arm becomes narrow. This narrowing can block or slow blood flow to your arm and sometimes to your brain. Because of this, your arm may not get enough oxygen-rich blood. Over time, this can cause problems with movement or even pain. Early detection is important, so you can get the right treatment and avoid serious issues.
Common Symptoms
Many people with subclavian artery stenosis do not notice symptoms at first. However, as the blockage gets worse, signs may appear. For example, you might feel tired or weak in one arm. Sometimes, you may notice other changes.
If you notice these symptoms of subclavian artery stenosis, it is important to talk to your doctor. Early care can help prevent more serious problems.
Causes and Risk Factors
Most often, subclavian artery stenosis happens because of a buildup of fatty deposits, called plaque, inside the artery. This process is known as atherosclerosis. As plaque builds up, it makes the artery narrower and harder for blood to flow.
Several risk factors can increase your chances of developing this condition. For instance, some people are more at risk due to their lifestyle or health history.
Because these risk factors are common, it is important to manage them early. Making healthy choices can lower your risk of arm blood flow blockage.
How is It Diagnosed?
Doctors use several tests to check for subclavian artery stenosis. First, your doctor will ask about your symptoms and medical history. Next, they may check the blood pressure in both arms. If there is a big difference, it can be a sign of blockage.
To confirm the diagnosis, your doctor may order imaging tests, such as:
These tests help your doctor find the exact spot and size of the blockage. Early diagnosis of subclavian artery stenosis can lead to better treatment results.
Treatment Options
Treatment for subclavian artery stenosis depends on how severe the blockage is and your overall health. In mild cases, lifestyle changes and medicine may be enough. However, if the blockage is serious, you may need a procedure.
Your doctor will help you choose the best treatment for your needs. With the right care, most people feel better and lower their risk of problems.
Prevention and Lifestyle Tips
Although you cannot change some risk factors, you can take steps to protect your arteries. For example, healthy habits can lower your risk of subclavian artery stenosis and other heart problems.
By making these changes, you can improve your heart health and reduce the risk of arm blood flow blockage.
When to See a Doctor
If you notice symptoms like arm pain, weakness, or a big difference in blood pressure between arms, see a doctor soon. Early care can prevent serious problems, such as stroke or severe arm pain. In addition, if you have risk factors like high blood pressure or diabetes, regular check-ups are important. Find a cardiologist near you for expert advice and care.
