What is subclavian stent?
What is subclavian stent?
A subclavian artery stent is a small wire mesh tube that is used to hold open a sublcavian artery that has been narrowed by artery disease (atherosclerosis). Then a thin tube with a balloon at its tip (called a balloon catheter) is inserted over the guide wire until it reaches the femoral artery.
What is a subclavian artery occlusion?
Subclavian artery thrombosis is a condition in which the blood flow through the subclavian artery is obstructed. The occlusion typically arises secondary to damage to the intima of the vessel.
What artery is most commonly occluded with subclavian steal syndrome?
The most defined syndrome is the subclavian steal syndrome. In this condition, occlusive disease in the proximal subclavian artery can lead to a siphoning of blood away from the brain by a reversal of flow down the vertebral artery on the affected side to the ischemic limb.
What are the side effects of having a stent?
The risks associated with stenting include:
- an allergic reaction to medications or dyes used in the procedure.
- breathing problems due to anesthesia or using a stent in the bronchi.
- bleeding.
- a blockage of the artery.
- blood clots.
- a heart attack.
- an infection of the vessel.
- kidney stones due to using a stent in the ureters.
Can subclavian steal cause Stroke?
With subclavian steal syndrome, if neurologic symptoms do occur, they tend to be transient (eg, hypoperfusive transient ischemic attack) and seldom lead to stroke.
Which arm has higher blood pressure in subclavian steal?
Ninety-four percent of patients with subclavian steal have a systolic blood pressure that is 20 mm Hg or more, which is lower on the affected arm (the mean difference between the arms is 45 mm Hg in affected patients).
What are the treatment options for subclavian steal syndrome?
However, if the cause of subclavian steal syndrome is determined to be atherosclerotic stenosis or occlusion of the proximal subclavian artery, patients should be treated with lifelong antiplatelet therapy to reduce the risk of associated myocardial infarction, stroke, and other vascular causes of death.
What is subclavian artery stenosis?
The Subclavian Artery stenosis is also known as the peripheral Artery disease or the Subclavian Artery disease. It is a chronic condition and can lead o he death if ignored for long. The resulting condition from it is hand claudication, cerebral hyperperfusion and other such medical problems.
What is the function to the right subclavian artery?
Anatomy. The left and right subclavian arteries are located in the thorax (chest) underneath the clavicles (commonly known as the collarbones).
What is subclavian artery thrombosis?
Subclavian artery thrombosis is a blockage of the subclavian artery by a blood clot. Injury to a vessel and narrowing due to fatty plaques (atherosclorosis) are common predisposing factors of a blockage of an artery with a blood clot. This is typically seen with older people.
