The aortic arch is characterized by the origin of 3 collateral branches whose usual order of irruption corresponds to: brachiocephalic arterial trunk, left common carotid artery, and left subclavian artery. The anatomical variations of these supra-aortic trunks are the consequence of alterations in the embryonic development of the primitive aorta. In the present study, we report and analyze the case of an aberrant right subclavian artery in association with a non-recurrent right inferior laryngeal nerve, variants observed during deep mediastinal dissection of a formalin-preserved male cadaveric specimen. The aberrant right subclavian artery originated from the posterior face of the aortic arch, adjacent and lateral to the left subclavian artery, describing a retroesophageal course, to then continue its usual course towards the right axillary fossa, crossing the interscalene triangle. As a variant dependent on the aberrant artery, the right inferior laryngeal nerve was observed with a non-recurrent course, whose origin was located at the cervical level. Based on the findings and the consulted bibliography, an analysis of the incidence of this variation, its embryogenic origin and its clinical consequences was carried out. [ABSTRACT FROM AUTHOR]

Cardiac malformations represent almost half of the malformations at birth, being conjoined twins a much less frequent variant, predominantly female. The case of toracodimus siamese twins, where there is an asymmetric development and there is a well formed fetus and a rudimentary fetus, finding in the latter heterotaxia, and a congenital malformation of the aortic arch, presented as aberrant right subclavian artery. We present its descriptive anatomy, the clinical significance of this malformation and its incidence of occurrence, this being a unique case. [ABSTRACT FROM AUTHOR]

Introduction: Variations of the aortic arch are anatomically interesting, although they acquire greater interest when their presentation justifies some type of symptoms. The origin and path of vessels that originate in the aortic arch are not always the same. The aim of this paper is to report a case of lusory artery and to describe the anatomical variants of the aortic arch reported in the literature. Case report: We present a female patient, 49 years old, who consulted for 6 months dysphagia. A neck and chest tomography with intravenous contrast was requested. It demonstrate an aberrant subclavian artery. Discussion: Clinically, aberrant subclavian artery usually presents asymptomatically. We could summarize the different presentation variants according to the number of vessels that originate in the aortic arch. In this way, the aortic arch can give rise to two (18%), three (75%) or up to four (7%) vessels. The lusory artery is a rare but probable variant of presentation. Although most are asymptomatic, dysphagia is the most frequent symptom. [ABSTRACT FROM AUTHOR]

Objectives: Congenital vascular malformations of the major arteries in the chest have been classified into 5 groups: 1) double aortic arch; 2) right aortic arch with left ligament or persistent ductus arteriosus; 3) aberrant subclavian artery; 4) aberrant left pulmonary artery, and 5) anomalous innominate artery. We reviewed the patients with aberrant right subclavian artery and their treatment. Methods: We studied retrospectively the records of 29 patients with aberrant right subclavian artery in childhood, from January 1992 to December 2012, analyzing the following variables: age at onset, clinical manifestations, associated cardiovascular defects, diagnosis and surgical approach method. Results: We found that most patients have an asymptomatic course, only 31% of them course with symptoms during the first year of life, with an incidental diagnosis of 35% during catheterization or other imaging studies. Patent ductus arteriosus was the most frequently associated congenital malformation, with 13%. Down's syndrome was found in 21%. The most common treatment was surgical section of the aberrant subclavian artery to release the esophagus. Conclusions: This vascular abnormality must be suspected in those patients with dysphagia, dyspnea, chest pain during feeding or breathing difficulties. A significant number of patients are not diagnosed in time, some reach adulthood without a diagnosis. This malformation is often found in imaging studies when evaluating the aorta or in a gastroesophageal reflux study, in which the barium bolus reveals the extrinsic compression of the esophagus.

We present the first case of aberrant right subclavian artery in interruption of the aortic arch that was diagnosed in the Children Hospital of the Sonora State in a newborn male whom had symptoms of distress respiratory, cyanosis and precordial murmur. Physical exam suggested Di George syndrome phenotypic characteristic and in his hospital stay had persistent hypocalcemia. Diagnosis of the interruption of the aortic arch type B was made by Echocardiography 2D and the other vascular anomaly associated, by computed tomographic angiography that permitted for identifying anatomic features from aberrant origin of the right subclavian artery leaving from interrupted distal aortic segment. We recommended to make this study as a complement for evaluation of this patients when is not possible to detect by Echocardiography and other associated vascular anomalies as in this case.
