Radial Recurrent Artery: Description and Clinical Significance

The radial recurrent artery, also known as a. recurrens radialis, pna, bna, jna, is an important blood vessel that plays a key role in supplying blood to the upper limb. This artery originates from the radial artery in the forearm, runs up the hand and forearm, and then turns back at the top of the forearm to pass between the radius and the biceps brachii muscle.

Once the radial recurrent artery reaches the shoulder, it divides into two main branches: anterior and posterior. The anterior branch continues its path forward and down the shoulder, providing blood supply to the muscles and skin of the shoulder. The posterior branch goes backward, providing blood supply to the tissues of the back of the shoulder and hand.

The radial recurrent artery is of great clinical importance, since its damage can lead to serious consequences for human health. For example, stenosis or occlusion of this artery can lead to ischemia of the upper extremity, which can manifest as numbness, weakness and pain in the arm, as well as sensory disturbances.

In addition, the radial recurrent artery can be damaged by trauma, such as a fracture of the radius or a sprained shoulder muscle. In such cases, surgery may be required to restore blood supply to the upper limb.

In conclusion, the radial recurrent artery is an important blood vessel that plays a key role in supplying blood to the upper limb. Damage to this artery can lead to serious consequences for a person's health, so it is important to seek medical help for any symptoms or problems in the upper limb.
