Abstract

The thoracoacromial artery may be missing. In Poynter's series it was the second branch in 47% of individuals studied. In some cases the arteries that make up the trunk arise separately, and in other cases it may have four branches; supreme (superior) thoracic, thoracic branch of the thoracoacromial, accessory pectoral branches, and lateral thoracic. The thoracoacromial artery may send a branch to pectoralis minor (8%) This artery may have a common origin with some other artery in 24% of individuals.

The thoracoacromial artery may be missing.

In Poynter's series it was the second branch in 47% of individuals studied.

In some cases the arteries that make up the trunk arise separately, and in other cases it may have four branches; supreme (superior) thoracic, thoracic branch of the thoracoacromial, accessory pectoral branches, and lateral thoracic.

The thoracoacromial artery may send a branch to pectoralis minor (8%)

This artery may have a common origin with some other artery in 24% of individuals.

The first part of the axillary artery may, in rare cases, give rise to the subscapular artery or supply a branch to the subscapular muscle.
