2023年11月30日 · Subclavian artery stenosis is the narrowing of an artery that provides blood to your arm. This narrowing usually happens because of a buildup of plaque inside your artery (but there are multiple other causes). It’s like a speed bump inside your artery that slows down the blood moving through it.

Subclavian artery stenosis is uncommon. The cause is typically atherosclerosis. It is usually a disease of smokers and of diabetics. There are other causes, such as vasculitis and trauma, among others. The left subclavian artery is involved more often than the right. While some patients have symptoms, most do not.

2023年6月21日 · Subclavian artery stenosis is most commonly caused by atherosclerosis, usually affecting the left subclavian artery. Prevention is essential, and the same measures apply to preventing the worsening of the condition or restenosis following surgery.

2022年8月3日 · Thoracic outlet syndrome causes stenosis (narrowing) of your artery, limiting blood flow and affecting your arms. Takayasu’s arteritis , a type of vasculitis , can cause inflammation in your subclavian artery and a lack of oxygen to your head and neck or arms.

2018年1月31日 · Subclavian artery disease develops when blood flow is decreased because a section of one of these arteries has become narrow or is blocked. This blockage is often caused by the buildup of plaque—fat, cholesterol and other substances—also called atherosclerosis.

2021年6月22日 · Stenosis (narrowing) of the subclavian artery is most commonly caused by atherosclerosis, and it usually affects the left subclavian artery. It may be suspected if a large difference in blood pressure readings is found between the arms.

Subclavian artery stenosis can be a cause of significant mor-bidity as it can lead to symptomatic ischemic issues affect-ing the upper extremities, brain and in some cases the heart.

Patients with PAD may have stenosis (i.e., narrowing) of the subcla-vian artery.1 Although atherosclerosis is the most common cause of blockage in the subclavian artery, other rare disorders, such as vasculitis, can also cause problems.

Subclavian steal syndrome results from significant subclavian stenosis and may cause coronary ischemia in patients with an internal mammary bypass graft, symptoms of vertebrobasilar insufficiency, or upper extremity claudication.

2019年1月2日 · The subclavian steal syndrome is a functional basilar artery insufficiency that is attributed to the decrease in pressure distal to the subclavian stenosis leading to a reversed pressure gradient across the vertebral artery on the diseased side.
