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 isolated left subclavian artery is shown. Anomaly results from interruption of left arch at two levels; one level is between left common carotid and left subclavian arteries and other level is distal to attachment of left ductus. Left subclavian artery does not have connection with aorta, but is connected to pulmonary artery by left ductus arteriosus. 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, ILSA = isolated left subclavian artery

Figure 14: Diagram of development of right aortic arch with isolated left subclavian artery is shown. Anomaly results from interruption of left arch at two levels; one level is between left common carotid and left subclavian arteries and other level is distal to attachment of left ductus. Left subclavian artery does not have connection with aorta, but is connected to pulmonary artery by left ductus arteriosus. 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, ILSA = isolated left subclavian artery

Mentions: An RAA with isolation of the LSA is the rarest type (5). This anomaly results from interruption of the left arch at two levels, with one level between the left common carotid and left subclavian arteries and the other level distal to the attachment of the left ductus (Fig. 14). The left carotid artery arises as the first branch of the right arch, followed by the right carotid artery and right subclavian arteries. The LSA does not have a connection with the aorta, but is connected to the pulmonary artery by a left ductus arteriosus. This rare anomaly may cause congenital subclavian steal syndrome and vertebrobasilar insufficiency. Rarely, the anomaly is associated with congenital heart disease, especially tetralogy of Fallot (10).
