“…In the case described, the right vertebral artery was not a branch of the right subclavian artery, but arose as a branch of the right common carotid artery. The ARSA left the thoracic cage through the upper thoracic orifice [18]. This departure of the right vertebral artery is not the rule, when ARSA is present, however, as Ito et al describing two cases of ARSA on cadavers found vertebral arteries departing from the subclavian arteries in both cases [19].…”

Atrophy of the fourth right aortic arch during embryogenesis can lead to arteria lusoria. This occurs with a frequency of 0.5-2%. This artery originates directly from the aortic arch as a fourth branch or from the proximal part of the descending aorta. Then it follows an upward and rightward direction crossing the trachea and esophagus in its course. This abnormal artery is accompanied in 20-60% of cases by dilatation of its proximal part, called Kommerell's diverticulum. A correlation has been noted between the presence of arteria lusoria and chromosomal aberrations, mainly Down syndrome. Arteria lusoria in fetuses is diagnosed using ultrasound, and in adults, the gold diagnostic standard is computed tomography or magnetic resonance angiography. Consequences of arteria lusoria may include dysphagia (dysphagia lusoria), chronic cough, arteriooesophageal fistula, retrosternal pain, respiratory problems, and numbness of the right upper limb. Respiratory disorders accompanying arteria lusoria occur mainly in children because their trachea is less rigid than in adults and more prone to deformation. Arteria lusoria is a clinically significant marker of fetal congenital malformations. It also may be a cause of nonspecific symptoms in children and adults that should be considered during differential diagnosis.

“…At its origin, the diameter of the ARSA was 12.9 cm, at the intersection of the esophagus and trachea it was 9.9 cm, and after the costocervical trunk it was 8.4 cm. The left subclavian artery in its origin had a diameter of 8.3 cm [18].…”

Background: The aberrant origin of the right subclavian artery (ARSA), also known as the lusoria artery, is a congenital malformation with an incidence of 0.5–4.4%. Most cases are incidental due to minimal clinical manifestations. Computer tomography (CT) is important in diagnosing and evaluating these patients. Materials and Methods: We conduct a computerized search in two databases, PubMed and EMBASE, for articles published between 1 January 2022 and 31 December 2023, PROSPERO code: CRD42024511791. Eligible for inclusion were case reports and case series that presented the aberrant origin of the right subclavian artery. The main outcome was the highlighting of the morphological types of ARSA. In this context, we proposed a new classification system of this anomaly. The secondary outcome was the evaluation of the demographic distribution of the lusoria artery. Results: Our search identified 47 articles describing 51 patients with ARSA. The typical course for ARSA is retroesophageal, being registered in 49 out of 51 patients. This malformation is frequently associated with Kommerell diverticulum (15 out of 51), troncus bicaroticus (7 out of 51), and aberrant origins of the right vertebral artery (7 out of 51). We observed a higher incidence of the condition among women (32 out of 51) compared to men (19 out of 51). From a demographic point of view, ARSA is more frequent in the “44 to 57 years” and “58 to 71 years” age ranges. Conclusions: ARSA is a congenital malformation resulting from a defect in the development of the aortic arches. The imaging studies such as computer tomography play a defined diagnostic role.
