Mayo Clin Proc ; Eur J Cardiothorac Surg ; 12 1: Left subclavian artery was pull by a ligament which estrridor from a retroesophagic diverticulum from the descending aorta Figs. Presentation of the case Female patient, 11 months old, referred to our Institute for vomits and laryngeal stridor occurring since the neonatal age.

The magnetic resonance did not defined accurately the structures which formed the vascular ring. The sixth aortic arches originate the proximal portions of the branches of estdidor pulmonary artery and the right and left arterial ducts, the right one usually disappears and the left one keeps or remain patent during fetal life.

The Kommerell’s diverticulum represents the persistency of the distal segment of double aortic arch, generally the left one estrisor the proximal segment is atretic or disappears.

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. Aneurysm of aberrant subclavian artery with a review of the literature. Report of a case with tracheal compression. Surgical resection estriodr the diverticulum, and section of the ligament was done so disappearing the digestive, and respiratory symptoms.

The embryonic aortic arches definiicion 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.


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.

Mayo Clin North Am ; J Vase Surg ; 2: 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.

The surgical treatment is indicated in definidion with symptoms of airway or esophageal compression. 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.

Vascular anomalies causing tracheoesophageal compression. J Vase Surg ; The Mayo Clinic experience.

Dysphagia and definiion due to right aortic arch with Kommerell’s diverticulum. Kommerell and Kommerell’s diverticulum. Texas Heart Inst J ; 29 2: It is well known that the magnetic resonance is the best study to define this malformation.

J Thorac Cardiovasc Surg ; 75 2: On the other side the dorsal aorta between the third and fourth aortic arches known as carotid ducts, involute too.

Surgical repair of right aortic arch with aberrant left subclavian artery and left ligamentum arteriosum. In this patient, it was the cardiac catheterization which allowed to define the structures that constituted the vascular ring.

A cohort study and review of the literature. The embryological knowledge of the transformations of the aortic arches offers great assistance in the understanding of all the types of vascular rings. Malformations of the aortic system manifested as vascular rings. 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.


Surgical treatment of vascular rings: The patient was surgically treated in a successful way. J Am Board Fam Pract ; 12 3: The third aortic arches persist and esttridor the proximal parts of the internal carotid arteries.

Stridor in a 6 week old infant caused by right aortic arch with aberrant left subclavian artery. J Thorac Cardiovasc Surg ; 97 5: Estridlr patient, 11 months old, referred to our Institute for vomits and laryngeal stridor occurring since the neonatal age.

Two cases of “asthma” revealing a diverticulum of Kommerell. Respiration ; 69 5: Lav Invest ; 2: 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 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.

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. Review of experience in children.
