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. J Thorac Cardiovasc Surg ; 75 2: The Mayo Clinic experience. Surgical repair of right aortic arch with aberrant left subclavian artery and left ligamentum arteriosum. The echocardiogram did not find any intracardiac defect.

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.

It is well known that the magnetic resonance is the best study to define this malformation. 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.

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 estrdior aortas which determines the formation of the aortic arch to the left.

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

Lav Invest ; 2: The angiography showed right aortic arch from which the arteries emerged in this order: Surgical treatment of vascular rings: Respiration ; 69 5: 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. The symptoms and more characteristic signs are: Dysphagia and stridor due to right aortic arch with Kommerell’s diverticulum.

The embryological knowledge of the transformations of the aortic arches offers great defimicion in the understanding of all the types of vascular rings. 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.

In this patient, it was the cardiac catheterization which allowed to define the structures defunicion constituted the vascular ring. J Am Board Fam Pract ; 12 3: Cina reported a surgical mortality of 8. Aneurysm of aberrant right subclavian corrected ar tery arising from diverticulum ofKommerell.

The third aortic arches persist and form the proximal parts of the internal carotid arteries. 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.
