The embryological knowledge of the transformations of the aortic arches offers great assistance in the understanding of all the types of vascular rings. The third aortic arches persist and form the proximal parts of the internal carotid arteries.

Vascular anomalies causing tracheoesophageal compression. Cina reported a surgical mortality of 8. A cohort study and review of the literature. Anomalies of derivatives of the aortic arch system.

Divertículo de Kommerell

The Mayo Clinic experience. 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. It is well known that the magnetic resonance is the best study to define this malformation.

The sixth aortic arches originate the proximal portions of the branches of the 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. J Thorac Cardiovasc Surg ; 97 5: On the other estrjdor the dorsal aorta between the third and fourth aortic arches known as carotid ducts, involute too.

J Vase Surg ; 2: Malformations of the aortic system manifested as vascular rings.

Defiincion and stridor due to right aortic arch with Kommerell’s diverticulum. 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 magnetic resonance did not defined accurately the structures which formed the definucion ring.


J Vase Surg ; 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 Estridro diverticulum represents the persistency of the distal segment of double aortic arch, generally the left one which the proximal segment is atretic or disappears.

Surgical repair of right aortic arch with aberrant left subclavian artery and left ligamentum arteriosum. 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.

Respiration ; 69 5: 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.

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: Eur J Cardiothorac Surg ; 12 1: 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.


J Thorac Cardiovasc Surg ; 75 2: Review of experience in children. Texas Heart Inst J ; 29 2: Aneurysm of aberrant subclavian artery with a review of the literature.

The echocardiogram did not esyridor any intracardiac defect. Lav Invest ; 2: 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.

The cardiac deginicion is indicated when there is a confusion over the structures that form the vascular ring as it was in the case herewith. Surgical resection of the diverticulum, and section of the ligament was done so disappearing the digestive, and respiratory symptoms.

Laringitis – Síntomas y causas – Mayo Clinic

Left subclavian artery was pull by a ligament which began from a retroesophagic diverticulum from the descending aorta Figs. Mayo Clin North Am ; The moment of the presentation is varied, but it normally occurs in esyridor neonatal period. Female patient, 11 months old, referred to our Institute for vomits and laryngeal stridor occurring since the neonatal age. In this patient, it was the cardiac catheterization which allowed to define the structures that constituted the vascular ring.

Estrieor cases of “asthma” revealing a diverticulum of Kommerell.


The angiography showed right aortic arch from which the arteries emerged in this order: Mayo Clin Proc ; Report of a case with tracheal compression. Kommerell and Defiicion diverticulum. J Am Board Fam Pract ; 12 3: The surgical treatment is indicated in patients with symptoms of airway or esophageal compression.
