In the human body, the lateral thoracic artery (or external mammary artery) is a blood vessel that supplies oxygenated blood to approximately one-third of the lateral structures of the thorax and breast.
It originates from the axillary artery and follows the lower border of the pectoralis minor muscle [1] to the side of the chest to supply the serratus anterior muscle, [2] pectoralis major muscle [3] and pectoralis minor muscle, [4] and sends branches across the axilla to the axillary lymph nodes and subscapularis muscle.
It anastomoses with the internal thoracic artery, subscapular, and intercostal arteries, and with the pectoral branch of the thoracoacromial artery. [5]
In the female it supplies an external mammary branch which turns round the free edge of the pectoralis major and supplies the breasts. [5]
The variations in Axillary Artery are Quite a lot, Thus;
Differences in its origin, course, branching pattern, and size. Some individuals may have variations in the number or arrangement of branches arising from the artery. Additionally, anatomical variations such as accessory or duplicated lateral thoracic arteries have been reported in medical literature. These variations can impact surgical procedures and diagnostic imaging interpretations.
In case it is absent the lateral perforating branches of Intercostal arteries take its place. [5]
