Summary

A rare celiacomesenteric trunk, where the celiac trunk and superior mesenteric artery share a common origin, was found in a cadaver dissection. This anatomical variation occurs in 1-2.7% of individuals and is important for upper abdominal surgery.

Area of Science:

  • Anatomy
  • Embryology
  • Vascular Surgery

Background:

  • The celiac trunk is the largest ventral branch of the abdominal aorta.
  • Variations in ventral splanchnic arteries arise from unusual embryological development.
  • Anatomical variations of the celiac trunk and superior mesenteric artery are clinically significant.

Purpose of the Study:

  • To describe a rare case of a celiacomesenteric trunk identified during cadaveric dissection.
  • To highlight the embryological basis and incidence of this anatomical variation.
  • To emphasize the clinical relevance of this variation in upper abdominal surgical procedures.

Main Methods:

  • Cadaveric dissection of a 54-year-old male.
  • Detailed observation and documentation of the arterial anatomy.
  • Review of existing literature on celiacomesenteric trunk variations.

Main Results:

  • A celiacomesenteric trunk was identified, with the celiac trunk and superior mesenteric artery originating from a single common trunk at the L1 vertebral level.
  • The incidence of this rare variation is reported to be between 1% and 2.7%.
  • This finding represents a significant deviation from the typical arterial branching pattern.

Conclusions:

  • The celiacomesenteric trunk is a rare anatomical variation with potential implications for surgical planning.
  • Understanding such variations is crucial for surgeons performing procedures in the upper abdomen.
  • Detailed case reports contribute valuable data for anatomical and surgical knowledge.
