CHARACTERISTICS OF THE THORACOACROMIAL ARTERY FOR LEFTING THE PECTORALIS MAJOR LOBE
Predrag KOVAČEVIĆ
Surgical Clinic of the Clinic Center, Niš
For the safe use of the pectoralis major lobe it is necessary for the surgeon to know its anatomic characteristics such as the vascular peduncle, the range of the vascular area and the lobe's rotation angle. The examination was done on 30 cadavers. The aim of the examination was to define exactly the anatomic characteristics as well as the vascular area of the pectoral initial thoracocromial artery essentially for lifting the pectoralis major lobe. In the 80% of the dissections the starting point of the artery is in the middle of the clavicula with an average length of 11,5 mm and width of 2,6 mm. In 83% of the dissections it was found that the thoracoacromial artery ended with 4 branches. It was found that the whole sternocostal part of the pectoral muscle is fed by the pectoral branch of the thoracoacromial artery as well as the sin of the front part of the thoracic cavity with average dimensions of 13x20 cm. The length of the lobe's rotation angle was from 22 to 28 cm. The examination exactly defined the starting point of the thoracoacromialis artery, the length of the pectoral branch and the area of its vascularization.
