Background
Congenital variants and anomalies of the aortic arch are important to recognize as they may be associated with vascular rings,
congenital heart disease (CHD),
and chromosomal abnormalities,
and can have important implications for prognosis and management,
including surgical and percutaneous interventions.
Aortic arch anomalies can occur in isolation but may also be associated with structural CHD.
However,
other arch variants,
such as right aortic arch with aberrant left subclavian artery,
are usually associated with normal intracardiac anatomy.
Detailed evaluation of aortic arch anatomy is important for planning thoracic surgery and endovascular intervention,
as the presence and pattern of arch variants and anomalies may influence the surgical incision,
cardiopulmonary bypass cannulation,
and interventional approach.
Arch anomalies may increase the technical difficulty of endovascular treatment including carotid stent procedures,
and the risk of neurologic complications.
Knowledge of aortic anatomy and identification of arch anomalies allows accurate surgical and intervention planning and helps avoid potential complications.
