Congenital anomalies of the aortic arch: evaluation with the use of multidetector computed tomography.

Türkvatan A, Büyükbayraktar FG, Olçer T, Cumhur T - Korean J Radiol (2009)

Bottom Line: Congenital anomalies of the aortic arch have clinical importance, as the anomalies may be associated with vascular rings or other congenital cardiovascular diseases.Multidetector computed tomography (MDCT) angiography enables one to display the detailed anatomy of vascular structures and the spatial relationships with adjacent organs; this ability is the greatest advantage of the use of MDCT angiography in comparison to other imaging modalities in the evaluation of the congenital anomalies of the aortic arch.In this review article, we illustrate 16-slice MDCT angiography appearances of congenital anomalies of the aortic arch.

ABSTRACT
Congenital anomalies of the aortic arch have clinical importance, as the anomalies may be associated with vascular rings or other congenital cardiovascular diseases. Multidetector computed tomography (MDCT) angiography enables one to display the detailed anatomy of vascular structures and the spatial relationships with adjacent organs; this ability is the greatest advantage of the use of MDCT angiography in comparison to other imaging modalities in the evaluation of the congenital anomalies of the aortic arch. In this review article, we illustrate 16-slice MDCT angiography appearances of congenital anomalies of the aortic arch.

Diagram of development of right aortic arch with mirror image branching. Anomaly results from interruption of dorsal segment of left arch between left subclavian artery and descending aorta with regression of right ductus arteriosus in hypothetical double aortic arch. AAo = ascending aorta, DAo = descending aorta, PA = pulmonary artery, T = trachea, E = esophagus, RSA = right subclavian artery, RCA = right carotid artery, LCA = left carotid artery, LSA = left subclavian artery, LIA = left innominate artery

Figure 12: Diagram of development of right aortic arch with mirror image branching. Anomaly results from interruption of dorsal segment of left arch between left subclavian artery and descending aorta with regression of right ductus arteriosus in hypothetical double aortic arch. AAo = ascending aorta, DAo = descending aorta, PA = pulmonary artery, T = trachea, E = esophagus, RSA = right subclavian artery, RCA = right carotid artery, LCA = left carotid artery, LSA = left subclavian artery, LIA = left innominate artery

Mentions: An RAA with mirror image branching is uncommon, but not rare (5). This anomaly results from interruption of the dorsal segment of the left arch between the LSA and the descending aorta, with regression of the right ductus arteriosus in the hypothetical double aortic arch (Fig. 12). The left innominate artery is the first branch arising from the arch, which is followed by the right carotid artery and right subclavian arteries (Fig. 13). This anomaly is usually associated with cyanotic congenital heart disease, especially tetralogy of Fallot and truncus arteriosus (9).
