Abstract Body : Introduction and Objective: The aberrant right subclavian artery (ARSA) represents an uncommon anatomical variation observed in the vascular system. This study aims to provide a narrative review encompassing the anatomical and epidemiological aspects of the aberrant right subclavian artery, along with a presentation of findings from dissections within one of Central Michigan University College of Medicine’s Summer Anatomy Dissections groups. The aberrant right subclavian artery, a deviation from the typical arterial pattern, holds significance in both anatomical studies and clinical contexts, and this review seeks to contribute insights into its prevalence, anatomical characteristics, and potential implications.




Materials and Methods: This study involved a comprehensive literature review utilizing PubMed (refer to details below). Articles were scrutinized with a focus on disorders and/or diseases associated with the aberrant right subclavian artery. Additionally, a case report is presented based on a cadaveric dissection conducted in the summer of 2023, contributing to the exploration of this anatomical variation.




Results: Our review incorporated nine articles spanning from 2013 to 2023, revealing an incidence range of anatomical variation from 0.16% to 4.4%. Several studies investigated the association between the aberrant right subclavian artery (ARSA) and Down's syndrome, as well as connections between ARSA and Kommerell's diverticulum. In our case report, we document the discovery of ARSA in a male donor with a history of numerous clots and vascular issues.




Conclusion: The occurrence of the aberrant right subclavian artery (ARSA) is relatively rare in the general population. It is crucial to possess a sound anatomical understanding of this artery to effectively identify it in patients, ensuring careful consideration before undertaking any maneuvers in the corresponding local region.




Significance and Implications: The importance of the aberrant right subclavian artery (ARSA) should not be underestimated, given the potential for misinterpretations in imaging and its impact on surgical procedures. A more extensive set of case studies is vital to comprehend its correlation with a diverse range of clinical disorders and disease processes.
