What is Subclavian's theft syndrome?

Subclavian syndrome is a condition in which a artery that normally pumps blood from the heart to the brain is narrowed or blocked, leading to a conversion in the direction of blood flow. Lack of blood supply to the brain can cause a person to experience dizziness, vision problems, insensitivity of arms and fainting. Subclavian syndrome is usually caused by the accumulation of calcium and cholesterol in the arteries, although blood clots or congenital defects can also lead to problems. In most cases, patients must undergo surgery to reopen or bypass the affected arteries.

The usual point of blocking or narrowing is the left subclavian artery, the branch of the aortic arch that extends up to the neck. Subclavian artery usually supplies blood to the vertebral artery, where it is transferred to the blood vessel system in the brain. In the case of the Subclavian theft syndrome, blocking reverse the blood flow in the vertebral artery, so that the brain does not receive a sufficient supply of new blood. A blood clot or a direct trauma of the chestthat also reduce and damage the subclavian artery. Rarely, a child can be born with a congenital defect that isolated by the subclavian artery from the rest of the heart and the circulatory system, causing it to be unable to receive and transport blood.

The most common symptoms of subclastic theft syndrome are blurred vision, dizziness and nausea. Reduced blood pressure in the upper body can cause the left arm to solidify and reduce the individual's ability to concentrate. It is also possible for a person to faint or have a stroke if blood supply to the brain is seriously limited.

Cardiovascular physician can diagnose Subclavian syndrome by analyzing symptoms and performing a number of diagnostic imaging tests. Ultrasound, computer tomography scan and chest X -rays can reveal the exact location or artery narrowing point. After diagnosis and identify the basic cause, the doctor may determine nBetter treatment. Most cases of subclavian theft syndrome do not respond to medical treatment and individuals usually have to undergo surgery.

Depending on the type and severity of the blockade, the cardiovascular surgeon may try to manually remove greasy deposits, insert the stent into a damaged artery, or perform the procedure. When it is necessary to stance, the surgeon inserts the hollow tube to make sure that the artery keeps its shape. The bypass includes redirecting of blood flow around the Subclavian artery with a donor or artificial tube. After treatment, the patient must usually reduce their physical activity and visit the pro -prepareable checks with a cardiovascular physician to ensure that the problems do not return.
