The embryological knowledge of the transformations of the aortic arches offers great assistance in the understanding of all the types of vascular rings.

Left subclavian artery was pull by a ligament which definicon from a retroesophagic diverticulum from the descending aorta Figs. 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.


Surgical treatment of vascular rings: On the estriror side the dorsal aorta between the third and fourth aortic arches known as carotid ducts, involute too.

Definicio 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.

Two cases of “asthma” revealing a diverticulum of Kommerell. Anomalies of derivatives of the aortic arch system. It is well known that the magnetic resonance is the best study to define this malformation.

estrkdor Aneurysm of aberrant subclavian artery with a review of the literature. J Am Board Fam Pract ; 12 3: 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.


J Thorac Cardiovasc Surg ; 75 2: 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.

In this patient, it estrudor the cardiac catheterization which allowed to define the structures that constituted the vascular ring. Kommerell and Kommerell’s diverticulum.

The patient was surgically treated in a successful way. Presentation of the case Female patient, 11 months old, referred to our Institute for vomits and laryngeal stridor occurring since the neonatal age. Lav Invest ; 2: The magnetic resonance did not defined accurately the structures which formed the vascular ring. Eur J Cardiothorac Surg ; 12 1: J Thorac Cardiovasc Surg ; 97 5: 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.

Mayo Clin North Am ; Surgical resection of the diverticulum, and section of the ligament was done so disappearing the digestive, and respiratory symptoms.

Malformations of the aortic system manifested as vascular rings. Surgical repair of right aortic arch with aberrant left subclavian artery and left ligamentum arteriosum. Usually it is not defiicion 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.


J Vase Surg ; 2: The third aortic arches persist and form the proximal parts of the internal carotid arteries. Dysphagia and stridor due to right aortic arch with Kommerell’s diverticulum. A cohort study and review of the literature. 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.

Texas Heart Inst J ; 29 2: The Mayo Clinic experience.

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 symptoms and more characteristic signs are: 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 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.

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

Stridor in a 6 week old infant caused by right aortic arch with aberrant left subclavian artery.
