The symptoms and more characteristic signs are: Surgical treatment of vascular deffinicion 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.

Stridor in a 6 week old infant caused by right aortic arch with aberrant left subclavian artery.

Two cases of “asthma” revealing a diverticulum of Kommerell. 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. 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 third aortic arches persist and form the proximal parts of the internal estrdior arteries.

The angiography showed right aortic arch from which the arteries emerged in this order: Kommerell and Kommerell’s diverticulum. Respiration ; 69 5: 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. The Mayo Clinic experience. Malformations of the aortic system manifested as vascular rings.

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 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 sefinicion the right dorsal aorta between this arch and the origin of the seventh segmentary artery, this last one constitutes the distal part.
