The moment of the presentation is varied, but it normally occurs in the neonatal period. The patient was surgically treated in a successful way.

Dysphagia and stridor due to right aortic arch with Kommerell’s diverticulum. Surgical resection of the diverticulum, and section of the ligament was done so disappearing the digestive, and respiratory symptoms. Report of a case with tracheal compression.

The angiography showed right aortic arch from which the arteries emerged in this order: The sixth aortic arches originate the proximal portions of the branches of the pulmonary artery and estirdor right and left arterial ducts, the right one usually disappears and the left one keeps or remain patent during fetal life. Left subclavian artery was pull by a ligament which began from a retroesophagic diverticulum from the descending aorta Figs.

J Thorac Cardiovasc Surg ; 75 2: 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. Surgical repair of right aortic arch with aberrant left subclavian artery and left ligamentum arteriosum. The echocardiogram did not find any intracardiac defect. The surgical treatment is indicated in patients with symptoms of airway or esophageal compression. The fourth aortic arches persist encircling the anterior gut, this estridod 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.


Aneurysm of aberrant subclavian artery with a review of the literature. Cina reported a surgical mortality of 8. The embryological knowledge of the transformations of the aortic arches offers great assistance in the understanding of all the types of vascular rings. Texas Heart Inst J ; 29 2: In this patient, it was the cardiac catheterization which allowed to define the structures that constituted the vascular ring.

The right ventral aorta give origin to the brachycephalic arterial trunk, from which the right common carotid artery esttridor 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 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. Kommerell and Kommerell’s diverticulum.

Lav Invest ; 2: J Thorac Cardiovasc Surg ; 97 5: The magnetic resonance did not defined accurately the structures which formed the vascular ring.

A cohort study and review of the literature. Respiration ; 69 5: Review of experience in children. The Mayo Clinic experience. 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 etridor the left aortic arch.

It is well known that deifnicion magnetic resonance is the best study to define this malformation. Eur J Cardiothorac Surg ; 12 1: Female patient, 11 months old, referred to our Institute for vomits and laryngeal stridor occurring since the neonatal age.

J Vase Surg ; Mayo Clin Proc ; Two cases of “asthma” revealing a diverticulum of Kommerell. 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. 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 catheterization is indicated when there is a confusion over the structures that form the vascular ring as it was in the case herewith. Vascular anomalies causing tracheoesophageal compression. J Am Board Fam Estrridor ; 12 3: 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. Surgical treatment of vascular rings: The third aortic arches persist and form the proximal parts of the internal carotid arteries.

On the other side the dorsal aorta between the third and fourth aortic arches known as carotid ducts, involute too. The Kommerell’s diverticulum represents the persistency of the distal segment of double aortic arch, definicionn 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. J Vase Surg ; 2: The symptoms and more characteristic signs are: Anomalies of derivatives of the aortic arch system.

Malformations of the aortic system manifested as vascular rings.
