An aberrant right subclavian artery, a rare aortic arch variation occurring in less than 1% of individuals, was identified during routine human cadaver dissection. This case report details its anatomy and embryological origins.

Area of Science:

  • Anatomy
  • Embryology
  • Vascular Surgery

Background:

  • Anatomical variations of the aortic arch branches can have clinical implications.
  • The aberrant right subclavian artery (ARSA) is a rare congenital anomaly.

Purpose of the Study:

  • To report a case of ARSA discovered during cadaveric dissection.
  • To review the embryology and anatomy of ARSA.
  • To discuss the clinical relevance of this vascular variation.

Main Methods:

  • Routine dissection of 230 adult human specimens.
  • Detailed description of the aortic arch and its branches.
  • Comparison with existing literature on ARSA.

Main Results:

  • Identification of an 82-year-old male donor with a retro-esophageal ARSA as the final branch of the aortic arch.
  • The incidence of this variation is noted to be less than 1%.

    • Conclusions:

    • ARSA is a rare aortic arch anomaly with specific embryological origins.
    • Detailed anatomical description and comparison with other cases are crucial for understanding its variations.
    • Awareness of ARSA is important for clinicians, particularly in vascular and cardiothoracic surgery.
