What is the treatment for left left subclavian artery stenosis?
Most subclavian blockages can be treated with stents, but in some cases, surgery may be needed. With surgery, blood flow is rerouted across the blockage using a small plastic tube called a bypass graft. Both stents and surgery are highly effective treatments and often help symptoms improve.
Where does the left subclavian artery end?
The subclavian artery is the artery that passes with the roots of brachial plexus between the anterior and middle scalene muscles, through the scalene space, over the first rib in the groove for the subclavian artery. It ends at the lateral border of the first rib and continues as the axillary artery.

The left main coronary artery supplies blood to the left side of the heart muscle (the left ventricle and left atrium). The left main coronary artery divides into branches: The left anterior descending artery branches off the left coronary artery and supplies blood to the front of the left side of the heart.
What is stenosis of the left subclavian artery?
In subclavian stenosis, the artery is simply narrowed, leading to decreased blood flow beyond the area of blockage. When the subclavian blockage is severe, or if the artery is completely blocked, a condition called ‘subclavian steal’ can occur (Figure 4).
Where are your carotid arteries located in your neck?
There are two carotid arteries: one on the left and one on the right. In the neck, each of them branches off into an internal carotid artery and an external carotid artery. The position of the branched carotid arteries is where a person can feel the pulse in their neck, just under the jaw.
