In surgical myocardial revascularization using both ITAs occurs a decrease in blood supply to the sternum and it is one of the causes of postoperative mediastinitis. Our study focused the sternal branches, from these ITAs, which are responsible for maintaining blood supply of the sternum after bilateral use of internal thoracic artery in myocardial revascularization. 60 internal faces of the anterior chest wall were dissected and formaldehyde preserved. The study consisted of 28 females and 32 males, the trunks and their branches were measured and photographed and statistical tests were applied. The most dissected sternal trunks found in 120 internal thoracic artery were the intercostal/sternal and the perforating/sternal. The preservation of these trunks is needed to prevent any disorder of the sternum.
