Double aortic arch is a rare congenital anomaly that accounts for about 1-2% of all kids with congenital heart disease. It is an unusual vascular anomaly that grows incorrectly and is classified as a complete vascular ring. Genesis Foundation which is a children\u2019s heart foundation, India provides financial aid to children with congenital anomalies.<\/p>\n

History of Double Aortic Arch
\n<\/strong>The first post-mortem description of a double aortic arch was made by Hommel in 1737. Then much later in the 1930s, the diagnosis of a vascular ring anomaly was accomplished with the advent of Barium esophagography.<\/p>\n

The first open surgical correction of a double aortic arch was done by\u00a0 Dr. Robert Gross from Boston Children\u2019s Hospital, who did division of the aortic arch through left thoracotomy on 7th<\/sup> June 1945.<\/p>\n

What is a Double Aortic Arch?
\n<\/strong>The double aortic arch is the most frequent type of aortic arch malformation to result in a vascular ring. The ascending aorta arises normally, and as it leaves the pericardium it divides into two branches, a left and a right aortic arch that join posteriorly to form the descending aorta.<\/p>\n

The left arch passes anteriorly and to the left of the trachea in the usual position and then becomes the descending aorta by the ligamentum arteriosum or the ductus arteriosus. The right aortic arch passes to the right and then posterior to the oesophagus to join the left-sided descending aorta, thereby completing the vascular ring.<\/p>\n

\"\"<\/p>\n

From each arch arises a carotid and a subclavian artery . These arches are usually not equal in size, the right arch is commonly the larger of the two. One arch may be represented by a single atretic segment; in that case, the right arch usually persists.<\/p>\n

Right-dominant arch is more common, accounting for approximately 75% of cases. Left-dominant aortic arch accounts for approximately 20% of cases, with the remaining 5% of cases having right and left aortic arches of equal calibre.<\/p>\n

Symptoms
\n<\/strong>The most common symptoms displayed by patients present at the time of diagnosis are those arising from the respiratory system.<\/p>\n

If such symptoms arise in a newborn or young infant and happen recurrently, the child should be shown to a physician with a possibility of the presence of arch anomalies.<\/p>\n

Diagnosis
\n<\/strong>There are several methods of diagnosis for a double aortic arch.<\/p>\n
