Summary

A rare anatomical variant, the celiac-bimesenteric trunk, originating from a single source for three major abdominal arteries, was identified in a 39-year-old man. This previously undescribed vascular anomaly offers insights into human embryology.

Area of Science:

  • Vascular anatomy
  • Human embryology
  • Gastrointestinal surgery

Background:

  • The celiac trunk, superior mesenteric artery, and inferior mesenteric artery typically arise independently from the abdominal aorta.
  • Variations in the origin of these major visceral arteries can impact surgical approaches and diagnostic interpretations.
  • Understanding rare arterial patterns is crucial for accurate anatomical assessment.

Observation:

  • A unique case of a 39-year-old male patient presented with an unusual common origin for the celiac, superior mesenteric, and inferior mesenteric arteries.
  • This previously undocumented anatomical variant was termed the 'celiac-bimesenteric trunk'.
  • The anomaly was visualized and confirmed using selective angiography.

Findings:

  • The study describes a novel trifurcation of the abdominal aorta supplying the celiac, superior mesenteric, and inferior mesenteric arteries from a single trunk.

  • This finding represents a significant deviation from standard human arterial anatomy.
  • An embryologic hypothesis is proposed to explain the development of this rare vascular pattern.

    • Implications:

    • The identification of the celiac-bimesenteric trunk expands the known spectrum of human arterial variations.
    • This anomaly may have implications for surgical planning in abdominal procedures, particularly those involving the upper gastrointestinal tract.
    • Further research into the embryogenesis of such variants can enhance our understanding of vascular development.
