Anatomical variations of the trunk of origin and terminal branches of the thoraco-acromial artery

Abstract

The thoracoacromial artery (TAA) is the main integumentary artery of the anterior deltoid region. It supplies part of the anterocranial wall of the thorax [1,2]. This region has been used for many years as a donor site for reconstructions of the neck and head, because it is close to the cervicofacial areas in terms of color, texture and thickness [3,4]. However, the thoracoacromial artery can be subject to anatomical variations, both regarding its birth mode than its terminal branching [4].
