KW  - Cervical aortic arch �?? Coarctation �?? Ductus caroticus anomaly �?? Rathke�??s aortic arch diagram
N2  - Coarctation of the cervical aortic arch (CAA), though rare, is a clinical entity of embryological significance. Based on Rathke�??s aortic arch dia-grams and Edward�??s concept of functioning double aortic arch, we are postulating that the coarctation in a CAA occurs due to partial involution of the dor-sal aorta developed from the �??ductus caroticus�?�. Hence coarctation in CAA should be classified as a �??clinically significant aortic arch anomaly of ductus caroticus origin�?�. Conversely, location of coarctation in CAA substantiates the theory that embryogenesis of CAA is due to aortic arch devel-opment from the third or second branchial arch vessel, rather than the usual fourth arch vessel.
