A cohort study and review of the literature.

Female patient, 11 months old, referred to our Institute for vomits and laryngeal stridor occurring since the neonatal age. Eur J Cardiothorac Surg ; 12 1: Texas Heart Inst J ; 29 2: The angiography showed right aortic arch from which the arteries emerged in this order: 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.

J Thorac Cardiovasc Surg ; 97 5: Surgical repair of right aortic arch with aberrant left subclavian artery and left ligamentum arteriosum. On the other side the dorsal aorta between the third and fourth aortic arches known as carotid ducts, involute too.

The symptoms and more characteristic signs are: 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.

The sixth aortic arches originate the proximal definicoin 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.

Vascular anomalies causing tracheoesophageal compression. 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.

The third aortic arches persist and form the proximal parts of the internal carotid arteries. Aneurysm of aberrant subclavian artery with a review of the literature. The fourth aortic arches persist encircling the anterior gut, this symmetry gives up an asymmetric pattern when one segment of the right dorsal refinicion normally involutes between the seventh segmental artery and the place of union of both dorsal aortas which determines the formation of the aortic arch detinicion the left.

The magnetic resonance did not defined accurately the structures which formed the vascular ring.

Review of experience in children. J Thorac Cardiovasc Surg ; 75 2: Usually it is not associated definciion 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 term vascular ring is referred to the alterations of the aortic arches in which the trachea and the estrudor are surrounded by these structures. The Mayo Clinic experience. The embryological knowledge of the transformations of the aortic arches offers great assistance in the understanding of all the types of vascular rings.

Aneurysm of aberrant right subclavian corrected ar tery arising from diverticulum ofKommerell. Anomalies of derivatives of the aortic arch system. Respiration ; 69 5: It is well known that the magnetic resonance is the best study to define this malformation. 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.

Stridor in a 6 week old infant caused by right aortic arch with aberrant left subclavian artery. Kommerell and Kommerell’s diverticulum. 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. Two cases of “asthma” revealing a diverticulum of Kommerell.

The moment of the presentation is varied, but it normally occurs in the neonatal period. Malformations of the aortic system manifested as vascular rings. Mayo Clin North Am ; 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.

Cina reported a surgical mortality of 8. In this patient, it was the cardiac catheterization which allowed to define the structures that constituted the vascular ring. Lav Invest ; 2: Mayo Clin Proc ; J Vase Surg ; J Am Board Fam Pract ; 12 3: Surgical resection of the diverticulum, and section of the ligament was done so disappearing the digestive, and respiratory symptoms. The surgical treatment is indicated in patients with symptoms of airway or esophageal compression.

The echocardiogram did not find any intracardiac defect. 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.
