The clavipectoral triangle (also known as the deltopectoral triangle) is an anatomical region found in humans and other animals. It is bordered by the following structures:

  • Clavicle [1]
  • Lateral border of Pectoralis Major muscle [2]
  • Medial border of Deltoid muscle [3]

It contains the cephalic vein,[4] and deltopectoral fascia, which is a layer of deep fascia that invests the three structures that make up the border of the triangle, and also the cephalic vein in the triangle. The deltoid branch of the thoracoacromial artery also passes through this triangle, giving branches to both the deltoid and pectoralis major muscles.

The subclavian vein and the subclavian artery may be accessed via this triangle, as they are deep to it.
