aortic arch

The aortic arch is a crucial part of the aorta, the body's main artery. It emerges from the heart's left ventricle as the ascending aorta, then arches over the heart before descending. This arch gives rise to three major arteries that supply oxygenated blood to the head, neck, and arms.1

Disorders affecting this area are known as aortic arch syndrome. These conditions often result from atherosclerosis, a buildup of fatty plaques that can block blood flow. A rare form, Takayasu's disease, primarily affects women and can lead to serious neurological issues like blindness and paralysis. Congenital defects, such as persistent ductus arteriosus or coarctation of the aorta, can also impact this region.2
