“…Along its course, an ARSA may cross the aortic arch transversely, posterior to the esophagus and the trachea in the direction of the right arm (in 80% of cases), anterior to the trachea (in 5% of cases), or even between the esophagus and the trachea (in 15% of cases), following a more linear path than the normal right subclavian artery. 16 , 17 , 18 , 19 …”

The aberrant right subclavian artery, also known as the arteria lusoria, is the most common aortic arch anomaly, occurring in 0.5 to 1% of the population. There is a higher prevalence in women and it is usually associated with other anatomical variations, such as the non-recurrent laryngeal nerve, present in 86.7% of cases. In the majority of cases, the aberrant right subclavian artery causes no symptoms. We describe this anomaly in an 82-year-old, hypertensive, and asymptomatic patient who had undergone a thoracoabdominal angiography to investigate a chronic DeBakey type III aortic dissection with dilation of the descending aorta. The aberrant right subclavian artery followed a retroesophageal course and was associated with a Kommerell diverticulum. In view of its rarity, we conducted an integrative bibliographic review of literature from the last 6 years indexed on the Medline, UpToDate, Lilacs, Scielo, and Portal Capes databases and discuss the most frequent anatomical changes, symptomatology, and therapeutic management adopted.

“…It results from an anomaly in the complex remodeling of the aortic arches during embryonic development [2]. The aberrant right subclavian artery is often discovered incidentally [3]. With the advancement and better availability of imaging techniques such as CT scans, this variant is frequently identified [4].…”

Background: The presence of a right aberrant subclavian artery, also known as the lusoria artery, is the most frequent anomaly of the aortic arch. The aim of this study was to describe the anatomy of the lusoria artery and its relationships on CT scans in melanoderm subjects at the CNHU-HKM in Benin. Methods: This was a descriptive cross-sectional study with retrospective data collection, conducted from January 2018 to December 2021 at the CNHU-HKM. It focused on thoracic angioscans and thoraco-abdomino-pelvic scans that revealed a lusoria artery in patients referred to the medical imaging department. The sampling was exhaustive. Image analysis was performed using Radiant DICOM Viewer software. Results: A total of 11 cases of lusoria artery were identified among the 732 scans studied, representing a frequency of 1.5%, with a sex ratio of 0.22. The mean age of the patients was 50.81 ± 14.54 years. The discovery of the lusoria artery was incidental in all patients. The lusoria arteries arose from the aortic arch, on average 7.59 mm after the left subclavian artery, with a mean diameter of 14.86 mm at the origin. They all had a retro-esophageal course. The bicarotid trunk was the most frequent associated anatomical variation (90.9%) with a mean length of 11.84 mm. This was followed by Kommerell's diverticulum (18.18%). One case of a common origin of the subclavian arteries and bicarotid trunk associated with the lusoria artery was noted. Conclusion: The lusoria artery is a rare anatomical variation that predominantly affects women. Often discovered incidentally, it arises from the aortic arch and has a retro-esophageal course. It is almost constantly associated with a bicarotid trunk. KEYWORDS: Lusoria artery - bicarotid trunk - CT scan - Kommerell's diverticulum - Benin.
