Right aortic arch occurs due to the persistence of the right branch with the regression of the left branch. Thoracic aortic aneurysm (adult). Connolly HM (expert opinion). WebOf paramount importance for evaluation of the thoracic aorta is the suprasternal view (Figure 2A).This view primarily depicts the aortic arch and the three major supra-aortic vessels (innominate, left carotid, and left subclavian arteries), with variable lengths of the descending and, to a lesser degree, ascending aorta. The arch terminates at the lower border of T4 where it continues as the descending aorta, in the plane of Ludwig, a horizontal plane from the sternomanubrial angle to the T4 vertebral body. The area just above where the abdominal aorta bifurcates (divides into two branches) into the iliac arteries is susceptible to a weakening of the aortic wall called an abdominal aortic aneurysm. Aortic aneurysms can develop anywhere in the body's main artery (aorta). The aortic arch also plays a role in blood pressure homeostasis via baroreceptors found within the walls of the aortic arch. The aorta is the pipe that helps oxygenated blood get from your heart to every part of your body from your brain to your digestive tract.
