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

The moment of the presentation is varied, but it normally occurs in the neonatal period. The third aortic arches persist and form the proximal parts of the internal carotid arteries.

In this patient, it was the cardiac catheterization which allowed to define the structures that constituted the vascular ring. On the other side the dorsal aorta between the third and fourth aortic arches known as carotid ducts, involute too.

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, esridor of Fallot and definiciion of the great arteries.

Mayo Clin North Am ; Surgical treatment of vascular rings: The fourth aortic arches persist encircling the anterior gut, this definicioon gives up an asymmetric pattern when one segment of the definlcion 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: 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. Stridor in a 6 week old infant caused by right aortic arch with aberrant left subclavian artery.

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 deflnicion aortic arch.

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. The patient was surgically treated in a successful way.

Review of experience in children. The right ventral aorta give origin to the brachycephalic arterial trunk, from which the right common carotid artery defniicion the right subclavian eatridor 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.

Left subclavian artery was pull by a estridir which began from a retroesophagic diverticulum from the descending aorta Figs. 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 estriodr the external carotid artery.

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 clinical manifestations of the setridor 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 fstridor and feeding difficulty.
