A rare aortic arch variation featured a common trunk (CT) branching into the brachiocephalic trunk (BT) and left common carotid artery (LCCA). This anatomical anomaly was identified during plastination for anatomical study.

Area of Science:

  • Anatomical variations
  • Human embryology
  • Vascular development

Background:

  • The aortic arch exhibits diverse developmental patterns.
  • Understanding aortic arch anatomy is crucial for diagnosing congenital heart defects and vascular anomalies.

Purpose of the Study:

  • To document and describe an unusual branching pattern of the aortic arch.
  • To compare morphometric data of aortic arch branches with existing literature.

Main Methods:

  • Observation of an aortic arch variation during the creation of transverse body slices.
  • Utilized E12 plastination technique for detailed anatomical visualization.
  • Measured the caliber and length of the main aortic arch branches.

Main Results:

  • A common trunk (CT) originated from the aortic arch, bifurcating into the brachiocephalic trunk (BT) and left common carotid artery (LCCA).
  • The LCCA arose 10.27 mm superior to the aortic arch, coursed ventrally to the trachea and esophagus, and positioned left of the esophagus.
  • Morphometric data of the branches were recorded for comparative analysis.

Conclusions:

  • The study identified and characterized a specific aortic arch branching anomaly.
  • This finding contributes to the known spectrum of aortic arch developmental variations.
  • Highlights the importance of detailed anatomical examination in plastination processes.
