There are two subclavian arteries that supply our arms with blood. The subclavian
arteries branch to the vertebral arteries, which carry oxygenated blood up to the
brain from the base of the neck. The right subclavian artery, which is located below
the   clavicle,   branches   off   the   brachiocephalic   trunk.   The   left   subclavian   artery
branches off the arch of the aorta and ends at the first rib's lateral edge, where it
turns into the axillary artery. Each subclavian artery is split into three parts of the
scalenus anterior muscle: the first, from the origin up to the muscle; the second,
approximates the muscle; and the third, lateral to the muscle. Each subclavian artery
extends about two centimetres above the neck's clavicle, which is located above the
pleura's apex. It is possible for an aneurysm, an abnormal blood vessel dilation, to
form in one subclavian artery or in both. Some of the most common causes of an
aneurysm   of   the   subclavian   artery   are   post-traumatic   causes   (e.g.,   being   shot),
thoracic   outlet   obstruction,   arteriosclerosis   (when   the   arteries   harden),   and
malpositionings.
