The right arch is often seen as high riding and projecting as a mass in the right paratracheal region 4. soft tissue indentation on the right side of the distal trachea.tracheal bowing to the left at the level of the right aortic arch.can be rarely associated with congenital heart disease.may be associated with congenital subclavian steal syndrome and vertebrobasilar insufficiency.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.type III: right-sided aortic arch with isolation of the left subclavian artery 1,6.rarely associated with other cardiovascular abnormalities.rarely symptomatic and is therefore usually incidental, although it can rarely cause esophageal and/or tracheal compression 10.in this variant, the left common carotid artery arises first, followed by the right common carotid, right subclavian, and then left subclavian arteries.occurs from interruption of the dorsal segment of the left arch between the left common carotid and left subclavian arteries with regression of the right ductus arteriosus in the hypothetical double aortic arch.associated with a Kommerell diverticulum 11.common 1, at least accounting for 39.5% of all right-sided arches 11.type II: right-sided aortic arch with aberrant left subclavian artery.usually associated with cyanotic congenital heart disease, including.in this variant, the left brachiocephalic trunk arises first, followed by the right common carotid and right subclavian arteries.occurs from interruption of the dorsal segment of the left arch between the left subclavian artery and the descending aorta, with regression of the right ductus arteriosus in the hypothetical double aortic arch.In most of the literature, though, it is reported as less common than type II 1 sometimes reported as the most common, accounting for up to 59% of all right-sided arches 11.type I: right-sided aortic arch with mirror image branching.Please note that the numbering of the types varies from publication to publication therefore, the abnormality should be described rather than merely numbered 1,7,11-13. Right-sided arches can be divided into at least three types. However, it causes symptoms when associated with other vascular anomalies ( vascular ring) due to compression of the esophagus and/or trachea. The majority of the patients are asymptomatic and it is discovered incidentally. There is a significant association with 22q11.2 deletion syndrome (DiGeorge syndrome) 14. A right-sided aortic arch is thought to occur in approximately ~0.1% (range 0.05-0.2%) of the population. ![]()
