External mammary artery
External mammary artery
The External mammary artery is a small artery that arises from the axillary artery, opposite the thoracoacromial artery. It is also known as the lateral thoracic artery.
Anatomy[edit | edit source]
The external mammary artery runs along the lateral edge of the pectoralis minor muscle, giving off several branches to the muscle and continuing towards the mammary gland. It supplies blood to the lateral part of the mammary gland and the overlying skin.
Clinical significance[edit | edit source]
The external mammary artery is of clinical significance in breast reconstruction surgery, where it can be used as a source of blood supply for a flap of tissue.
