'''Aortic arch with its branches and internal mammary arteries''' | '''Aortic arch with its branches and internal mammary arteries''' | ||
The aortic arch has three main branches. Coming from the heart the brachiocephalic trunk is the first. It gives rise to the right subclavian artery and the right common carotid artery. The next branches coming out of the aortic arch are the left common carotid and left subclavian arteries. Anatomic variations in these vessels can make coronary angiography via the radial artery more challenging than via the femoral artery. The Left and right internal mammary arteries start in the proximal part of both subclavian arteries and run down following the inner thoracic wall outside the pleural cavity. | |||
