If the aortic arch is on the right-side, a vascular ring should be suspected. Listening to the chest for murmurs is often part of the assessment.Ī chest X-ray is often done as a part of the initial evaluation. Occasionally, physical examination will find a weak pulse in an arm or the legs. While in asthma, the noise is at the end of expiration. With a vascular ring, the noisy breathing may be heard both during inspiration (breathing in) and expiration (breathing out). Physical examination may help characterize the "noisy breathing." This may help separate it from other more common problems such as asthma. A vascular ring can be discovered by chance during evaluation of an unrelated problem. Swallowing problems are uncommon in the first months of life.Ĭhoking or swallowing difficulties are more common in older children as the main symptoms. Worsening of breathing difficulties with feeding or during upper respiratory infections may be seen.Ĭhildren with double aortic arch defects show up earlier than those with right aortic arch defects. Vascular rings diagnosed in patients less than 6 months of age are usually a result of a patient having noisy breathing (stridor). Many patients do not have symptoms or have mild symptoms. Most vascular rings are not found before birth. There are many symptoms seen when vascular rings are present. The left-sided ligamentum arteriosum (scar tissue formed as a remainder of the ductus arteriosus within three weeks of birth) completes the vascular ring. The two most common differences of true vascular rings, are persistent double aortic arch and right aortic arch with abnormal connection of the left subclavian artery. When a baby is developing parts of the arch may not form correctly.
The aorta delivers oxygen to all parts of the body. The aorta is the largest artery in the body. They can affect the aortic arch resulting in the formation of a ring going around the trachea and esophagus. They are listed in three groups: vascular rings, the innominate compression syndrome, and pulmonary arterial slings These vessels known as arteries may carry blood to the body, to the lungs, or both. View a graphic summary of vascular rings. This may cause pressure on the esophagus or airway. This happens when normal vessels are in the wrong place. A vascular ring is a type of congenital (present at birth) defect.
