Coeliaco-Mesenteric Trunk-- A Rare Anomaly of the Coeliac Trunk

Abstract The Coeliaco-mesenteric trunk, characterized by the shared origin of the coeliac trunk and the superior mesenteric artery, represents a rare but clinically important anatomical variation within the abdominal vasculature. Knowledge of variations of the abdominal vascular system and their origins is of great importance to surgeons to ensure optimal patient outcomes and also to mitigate the potential complications that may arise due to this lack of knowledge. Present case : During routine dissection for 1 st year MBBS (2022-23), of the abdominal region of a 60 year-old male cadaver, there was an unusual presentation of multiple blood vessels at the level of origin of the coeliac trunk. Upon further dissection, the superior mesenteric artery was found to be originating from this group of arteries. This artery was found to be passing through mesentery upto transverse colon. No other distinct blood vessel was found at the level where the superior mesenteric artery usually originates. Conclusion : This case underscores the importance of thorough pre-operative assessment and awareness of anatomical anomalies to facilitate safe and effective management strategies.
