Aortic arch anomalies
Possible aortic arch anomalies include:
- right aortic arch
- double aortic arch
- aberrant subclavian artery
- aberrant innominate artery
The anomalies listed above may lead to tracheal and/or oesophageal obstruction. A right aortic arch alone does not cause obstruction but may form a ring when associated with a left ductus passing behind the oesophagus to the right arch.
Associated anomalies include:
- coarctation of the aorta
- patent ductus arteriosus
