1. Abberant right subclavian artery.2. Innominate artery compression syndrome.3. Right arch mirror image.4. Right arch with abberant left subclavian
artery.5. Double aortic arch.6. Double arch with atretic segment.

Most common arch anomaly. Not a true ring. Usually asymtomatic. Sometimes dysphagia lusoria when dilated
subclavian artery compresses esophagus posteriorly.

In children the brachiocephalic (innominate) artery is located more to the left and may compresses the trachea anteriorly.
The findings are: anterior compression of the trachea brachiocephalic (innominate) artery is located
more to the left and compresses the trachea.

Mirror-image variety of the left arch Asymptomatic Associated congenital heart disease in 98%,
mostly tetralogy of Fallot.

Left subclavian artery is the last branch. Obstructing anomaly.

The findings are: four vessel sign. double arch. right arch higher and larger. esophagus and trachea are completely
encircled.

Left arch is very small and has atretic posterior segment.
Still a four vessel sign.
