Congenital Anomalies of the Aorta

The correct answer is C

Explanation

The ascending aorta arises anterior to the trachea and divides into 2 arches which pass posterior and to the right and anterior and to the left of the trachea and esophagus, creating the vascular ring. T
he right arch gives off the right common carotid and subclavian arteries and the left arch gives off the left common carotid and subclavian arteries.The two arches rejoin posteriorly to form the descending aorta.



A double aortic arch presents with stridor, dyspnea, recurrent pneumonia dysphagia (less common than respiratory symptoms, more common after starting baby on solids); Other anomalies which however rarely cause dysphagia areLeft aortic arch with aberrant right subclavian artery -The incidence: 0.4 - 2.3%; most common congenital arch anomaly; in 37% of Down syndrome children with CHD Associated with: (1) Absent recurrent pharyngeal (2) CHD in 10 - 15% Course: (a) behind esophagus (80%)(b) between esophagus + trachea (15%)(c)anterior to trachea (5%)
