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.

J Am Board Fam Pract ; 12 3: Surgical resection of the diverticulum, and section of the ligament was done so disappearing estrridor digestive, and respiratory symptoms. 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.

The magnetic resonance did not defined accurately the definciion which formed the vascular ring. 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 defiincion, 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.

Surgical repair of right aortic arch with aberrant left subclavian artery and left ligamentum arteriosum. Stridor in a 6 week old infant caused by right aortic arch with aberrant left subclavian artery. The moment of the presentation is varied, but it normally occurs in the neonatal period. 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.

Two cases of “asthma” revealing a diverticulum of Kommerell. Texas Heart Inst J defijicion 29 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.

Presentation of the case Female patient, 11 months old, referred to our Institute for vomits and laryngeal stridor occurring since the neonatal age. The angiography showed right aortic arch from which the arteries emerged in this order: Review of experience in children.

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.

The symptoms and more characteristic signs are: Eur J Cardiothorac Surg ; 12 1: The sixth aortic arches originate the proximal portions eatridor 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.

In this patient, it was the cardiac catheterization which allowed to define the structures that constituted the vascular ring. Lav Invest ; 2: J Thorac Cardiovasc Surg ; 75 2: Aneurysm of aberrant subclavian artery with a review of the literature. Dysphagia and stridor due to right aortic arch with Kommerell’s diverticulum.

The Kommerell’s diverticulum represents the persistency of the distal segment of double aortic arch, edtridor the left one which the proximal segment is atretic or disappears. J Vase Surg ; 2: The third aortic arches persist and form the proximal parts of the internal carotid arteries. Report of a case with tracheal compression.


Malformations of the aortic system manifested as vascular rings. A cohort study and review of the literature.

Surgical treatment of vascular rings: Left subclavian artery was pull by a ligament which began from a retroesophagic diverticulum from the descending aorta Figs.

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. Mayo Clin North Am ; 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 of the left aortic arch.

Aneurysm of aberrant right subclavian corrected ar tery arising from diverticulum ofKommerell. The embryological knowledge of the transformations of the aortic arches offers great assistance in the understanding of all the types of vascular rings.

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. Cina reported a surgical mortality of 8.
