Subclavian Arterial Disease

Subclavian arterial disease, also known as subclavian steal syndrome and aortic arch syndrome, involves structural problems or blockages in the arteries that branch off from the aortic arch. The aortic arch is the top portion of the main artery carrying blood away from the heart.

Diagnosis & Treatment at UVA

At UVA, we can diagnose you by using these tests:

  • Ultrasound imaging
  • Computed tomography (CT) scan and CT angiography
  • Angiography

Your healthcare provider can help you choose the appropriate treatment. Here are some options. 


During an endarterectomy, a surgeon removes the plaque that causes a narrowing or blockage in the aortic arch arteries. This opens the affected artery and improves blood flow.

Angioplasty and Stenting

During angioplasty, your surgeon inflates a balloon inside the artery to open its walls. A stent helps to keep the artery open.
