Anomalies of derivatives of the aortic arch system. J Vase Surg ; 2: On the other side the dorsal aorta between the third and fourth aortic arches known as carotid ducts, involute too.

Aneurysm of aberrant subclavian artery with a review of the literature. Mayo Clin Proc ; The angiography showed right aortic arch from which the arteries emerged in this order: The fourth aortic arches persist encircling the anterior gut, this symmetry gives up an defunicion 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.

The echocardiogram did not find any intracardiac defect. 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. Cina reported a defnicion mortality of 8. Review of experience in children.

The symptoms and more characteristic signs are: Surgical treatment of vascular rings: 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.

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. Kommerell and Kommerell’s diverticulum.

Surgical repair of right aortic arch with aberrant left subclavian artery and left ligamentum arteriosum. In such situation the left ventral aorta forms the ascendent portion, the fourth left aortic arch originates definicin transversal part, and the left dorsal aorta gives rise the descendant portion of the left aortic arch.

The clinical manifestations of the vascular ring and the seriousness will depend directly on the compression 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.

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.

Presentation of the case Female patient, 11 months old, referred to our Institute for vomits and laryngeal stridor occurring since the neonatal age. The moment of the presentation is varied, but it normally occurs in the neonatal period. A cohort study and review of the literature.

In this patient, it was the cardiac defonicion which allowed to define the structures that constituted the vascular ring. 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. Texas Heart Inst J ; 29 2: They are divided in esyridor 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.

Stridor in a 6 week old infant caused by right aortic arch with aberrant left subclavian artery. J Thorac Cardiovasc Surg ; 97 5: The surgical treatment is indicated in patients with symptoms of airway or esophageal compression.

The embryological definlcion of the transformations of the aortic arches offers great assistance in the understanding of all the types of vascular rings. J Thorac Cardiovasc Surg ; 75 2: Left subclavian artery was pull by a ligament which began from a retroesophagic diverticulum from the descending aorta Figs. Respiration ; 69 5: Aneurysm of aberrant right subclavian corrected ar tery arising from diverticulum ofKommerell.
