What is the true aortic arch?

Aorta, the largest artery in the body, adds oxygenated blood directly from the heart. The blood passes through the aortic to a wide range of ever smaller arteries that branch and eventually into the capillaries, where the blood is supplied directly to the body cells. During the normal development of the fetus, several branches develop, but most of them disappear and leave an aortic arch that travels on the left side of the trachea or trachea. In about one of the thousands of birth, however, the aorta lies on the right side of the trachea and creates a right aortic arch.

Although the aortic arch on the right side is considered to be abnormality, in most cases it does not require any symptoms and requires no treatment. However, some conditions that often occur in conjunction with this unusual location may require surgical correction. One of them is the vascular ring of a true aortic arch, in which the abnormal location of the aorta leads to the vascular structure that completely surrounds the trachea and esophagus. With different arteries and branches of the aorta that circles it can bI will be narrowed by the trachea and esophagus, interfering with normal breathing and swallowing.

Another condition that requires attention is the mirror image aortic arch, which in 98% of cases is associated with a certain form of congenital heart defect. The most commonly observed in conjunction with this condition is a heart defect called Fallota tetralogy. It is a hole in the wall that divides the chambers of the left and right hearts, allowing to mix oxygenated and deoxygenated blood. Other defects include a partial blockage of a vein that takes blood from the left ventricle to the lungs and reinforce the left ventricular wall. Fallota tetralogy can be corrected surgically, but is often fatal if it is not treated.

persistent true aortic arch, see in dogs such as Irish Setters and German Shepherds, creating similar problems as problems caused by a vascular ring. This occurs when the location of an aortic arch formed during developmentThe fetus persists after birth, usually creates a ring around the esophagus that captures IT against the heart and limits food in the stomach. Puppies with this condition are malnourished and do not grow at the same speed as the others in the litter. It can be corrected surgically and after treatment puppies grow and develop at normal speed.
