J Am Board Fam Pract ; 12 3: 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 estrisor 75 definicino Mayo Clin Proc ; Texas Heart Inst J ; 29 2: It is well known that the magnetic resonance is the best study to define this malformation. The surgical treatment is indicated in patients with symptoms of airway or esophageal compression.

J Vase Surg ; 2: Report of a case with tracheal compression. The embryonic aortic arches system are bilateral vessels defimicion 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.

Surgical resection of the diverticulum, and section of the ligament was done so disappearing the digestive, and respiratory symptoms. 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.


Eur J Cardiothorac Surg ; 12 1: 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 definiciob old, among the most known are the persistent stridor and feeding difficulty.

Definicio term vascular ring is referred to the alterations of the aortic arches in which the trachea and the esophagus are surrounded by these structures. 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. Aneurysm of aberrant subclavian artery with a review of the literature.

Malformations of the aortic system manifested as vascular rings. The right ventral aorta give origin to the brachycephalic arterial trunk, from which the right common carotid extridor 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.

Respiration ; 69 5: The magnetic resonance did not defined accurately the structures which formed the vascular ring. 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 estriror segmental artery and the place of union of both dorsal aortas which determines the formation of the aortic arch to the left.


The third aortic arches persist and form the proximal parts of the internal carotid arteries. Vascular anomalies causing tracheoesophageal compression. J Thorac Cardiovasc Surg ; 97 5: The patient was surgically treated in a successful way. Dysphagia and stridor due to right aortic arch with Kommerell’s diverticulum.

The angiography showed right aortic arch from which the arteries emerged in this order: 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.

Laringitis – Síntomas y causas – Mayo Clinic

A cohort study and review of the literature. 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 Mayo Clinic experience. Anomalies of derivatives of the aortic arch system. J Vase Surg ; The embryological knowledge of the transformations of the aortic arches offers great assistance in the understanding of all the types of vascular rings.
