Artery Thoracic Internal

**Internal thoracic artery** is a paired vessel that runs inside the chest and provides blood circulation to the lungs and other internal organs. The internal structures of the chest are pierced by the following arteries: the descending aorta, the left gastric artery, the thoracoacromial artery and the right subclavian artery. These branches arise from the internal pectoral muscle, which surrounds the heart and lungs. The internal thoracic artery is divided into periaortic and paraaortic regions. When passing to the body of the aorta, the artery gives off two branches: - Descending thoracic; - Venous parietal.

The walls of the internal mammary artery are about 1 mm thick, so its disintegration is very dangerous and leads to death. In this regard, doctors are also afraid to perform operations on veins and arteries, which are located as close as possible to the lung and heart. The arteries of the chest are widely used in surgical practice for operations on organs located in this area. In addition, if pathology occurs as a result of age-related changes in the chest wall, this space is used to install implants and perform other interventions.
