Aims and objectives
Aortic arch variants result from errors in the embryologic development of the branchial arches.
Typically there are three main branches in the aortic arch: brachiocephalic trunk(BT),
left common carotid artery(LCCA) and left subclavian artery(LSA).
According to the literature this configuration is present in approximately 70-90% of people.[1-2]
In recent years there have been performed many studies evaluating aortic arch variants depicted on multidetector computed tomography(MDCT).[1-3]
However these studies included adult population only or adult and smaller pediatric population together.
MDCT offers excellent temporal and spatial resolution.
The usefulness of MDCT in the evaluation of aortic arch anomalies has been established.
[4-5]With the use of multiplanar and 3D images accurate delineation of the anatomy is provided.
In this study we present results of the prevalence of aortic arch variants in pediatric patients only,
depicted on MDCT over a 4 year period.
