Which five arterial vessels are commonly evaluated in an upper extremity arterial study?

The five arterial vessels that are commonly evaluated in an upper extremity arterial study are the subclavian, axillary, brachial, radial, and ulnar arteries. This selection encompasses the primary arteries supplying blood to the upper limb.

The subclavian artery is the main supply line from the aorta and branches into the axillary artery as it crosses the first rib. The axillary artery further continues into the brachial artery, which supplies blood down the arm. As the brachial artery travels toward the elbow, it bifurcates into the radial and ulnar arteries, which further supply the forearm and hand.

These vessels play crucial roles in ensuring adequate blood flow to the upper extremity, making them vital areas of assessment in an upper extremity arterial study. Evaluating these arteries can help identify peripheral vascular diseases, arterial occlusions, or other vascular abnormalities affecting the arm and hand.
