摘要:
In order to clarify the vascularization of the pectoralis major muscle by the pectoral branch of the thoracoacromial artery, morphometric investigations and selective injection studies of the vessel were performed. A comparison with the anatomical orientation points clinically used for locating the vessel and its course confirms that the origin of the artery is at a constant spot at half the sternoacromial distance; the main vessel axis, however, deviates considerably from the clinically used acromioxiphoid axis in lateral direction.The lumen of the thoracoacromial artery has a range of more than 150% of the smallest vessel. Atherosclerotic alterations are not the reason for this variety but only an additional handicap for the vessel capacity. Two types of muscle-perforating arteries were found, and the cutaneous area of blood supply was defined.
