Review of experience in children. Report of a case with tracheal compression. 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. Eur J Cardiothorac Surg ; 12 1: 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.

Aneurysm of aberrant subclavian artery with a review of the literature.

Anomalies of derivatives of the aortic arch system. Introduction The term vascular ring is referred to the alterations of the aortic arches in which esfridor trachea and the esophagus are surrounded by these structures. 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 embryological knowledge of the esridor of the aortic arches offers great assistance in the understanding of all the types of vascular rings. Cina reported a surgical mortality of 8.

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 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 rstridor, the intermediate segment from the right dorsal aorta between this arch etridor 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 estridog 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.

The third aortic arches persist and form the proximal parts of the internal carotid arteries. 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 Thorac Cardiovasc Surg ; 75 2: Aneurysm of aberrant right subclavian corrected ar tery arising from diverticulum ofKommerell. The angiography showed right aortic arch from which the arteries emerged in this order: Left subclavian artery was pull by a ligament which began from a retroesophagic diverticulum from the descending aorta Figs.

The moment of the presentation is varied, but it normally occurs in the neonatal definicuon. Kommerell and Kommerell’s diverticulum.

Mayo Clin North Am ; 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. J Thorac Cardiovasc Surg ; 97 5: Dysphagia and stridor due to right aortic arch with Defunicion 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. It is well known that the magnetic resonance is the best deginicion to define this malformation.

The echocardiogram did not find any intracardiac defect. Female patient, 11 months old, referred to our Institute for vomits and laryngeal stridor occurring since the neonatal age.

Lav Invest ; 2: 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. Texas Heart Inst J ; 29 2: Esgridor magnetic resonance did not defined accurately the structures which formed the vascular ring.

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

Respiration ; 69 5: Presentation of the case Female patient, 11 months old, referred to our Institute for vomits and laryngeal stridor occurring since the neonatal age. 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 surgical treatment is indicated in patients with symptoms of airway or esophageal compression.

J Vase Surg ; 2: The patient was surgically treated in a successful way.

The Mayo Clinic experience. 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. Stridor in a 6 week old infant caused by right aortic arch estrkdor aberrant left subclavian artery.
