The study presents the incidence of a variant terminal branch of the internal thoracic artery (ITA). The ITA's were cannulated in situ, injected with coloured latex and dissected together with its branches in 62 cadavers. Unlike the usual termination of the ITA bifurcating into the musculophrenic and superior epigastric arteries, this third branch arose from the medial border of the ITA at the level of the 6th costal cartilage. As it descends it inclines medially towards the angle between the xiphoid process and the 7th costal cartilage, giving off 2 or 3 fine branches to the lower sternum. It then passes deep to this angle and can be observed on the anterior surface of the xiphoid process, terminating in fine branches distributed to the inferior aspect of the xiphoid cartilage. It is proposed that this branch at the "trifurcation
