The sixth aortic arches originate the proximal portions of the branches of the pulmonary artery estridkr the right and left arterial ducts, the right one usually disappears and the left one keeps or remain patent during fetal life.

The embryonic aortic arches system are bilateral vessels which connect the ventral and dorsal aortas, this produces a bilateral vascular system that surrounds the fore gut intestine from which the trachea and the esophagus come from.

Review of experience in children. On the other side the dorsal aorta between the third and fourth aortic arches known as carotid ducts, involute too. Left subclavian artery was pull by a ligament which began from a retroesophagic diverticulum from the descending aorta Figs.

The angiography showed right aortic arch from which the arteries emerged in this order: Report of a case with tracheal compression.

Dysphagia and stridor due to right aortic arch with Kommerell’s diverticulum. Malformations of the aortic system manifested as vascular rings. Introduction The term vascular ring is referred to the alterations of the aortic arches in which the trachea and the esophagus are surrounded by these structures. Stridor in a 6 week old infant caused by right aortic arch with aberrant left subclavian artery. In such situation the left ventral aorta forms the ascendent portion, the fourth left aortic arch originates the transversal part, and the left dorsal aorta gives rise the descendant portion of the left aortic arch.

The cardiac catheterization is indicated when there is a confusion over the structures that form the vascular ring as it was in the defonicion herewith. The right ventral aorta give origin to the brachycephalic arterial trunk, from which the right common carotid artery and the right subclavian artery emerge, this last one has a tripartite origin, the proximal part derives from the right fourth aortic arch, the intermediate segment from the right dorsal aorta between this arch and the origin of the seventh segmentary artery, this last one constitutes the distal part.

Presentation of the case Female patient, 11 months old, referred to our Institute for vomits and laryngeal stridor occurring since the neonatal age. J Vase Surg ; estriror Surgical repair of right aortic arch with aberrant left subclavian artery and left ligamentum arteriosum. J Vase Surg ; The symptoms and more characteristic signs are: The surgical treatment is indicated in definjcion with symptoms of airway or esophageal compression.

Usually it is not associated with other congenital heart disease, some authors have reported the ventricular septal defect as the most frequent malformation, other series mention aortic coartation, tetralogy of Fallot and transposition of the great arteries.

Surgical resection of the diverticulum, and section of the ligament was done so disappearing the digestive, and respiratory symptoms. Texas Heart Inst J ; 29 2: The clinical manifestations of the vascular ring and the seriousness will depend directly on the definucion degree, in most of the patients the symptoms will appear before one month old, among the most known are the persistent stridor and feeding difficulty.

Kommerell and Kommerell’s diverticulum. The third aortic arches persist and form the proximal parts of the internal carotid arteries.

The fourth aortic arches persist encircling the anterior gut, this symmetry gives up an asymmetric pattern when one segment of the right dorsal aorta normally involutes between the seventh segmental artery and the place of union of both dorsal aortas which determines the formation of the aortic arch to the left.

Female patient, 11 months old, referred to our Institute for vomits and laryngeal stridor occurring since the neonatal age.

Aneurysm of aberrant subclavian artery with a review of the literature. The Kommerell’s diverticulum represents the persistency of the distal segment of double aortic arch, generally the left one which the proximal segment is atretic or disappears.

The Mayo Clinic experience. They are divided in complete and partial; the former are the double aortic arch and the latter come from the aberrant origin of a subclavian artery, or arterial ligament or duct, counterside to the aortic arch. The distal parts of the first and second arches disappear close to the dorsal aorta, and the proximal areas of them close to the ventral aorta keep on as hyoid and maxillary arteries respectively, which are branches of the external carotid artery.

The term vascular ring is referred to the alterations of the aortic arches in which the trachea and the esophagus are surrounded by these structures.
