Abstract
Accessory splenic arteries in the gastrosplenic ligament constitute one of the extremely sub-component of abdominal vasculature variations and it is imperative to recognize this anomaly while planning for complex surgeries in the supra-colic compartment. We report the case of accessory splenic arteries in an approximately 50-year-old male cadaver encountered during routine educational dissection. One of them arising from left gastroepiploic artery supplies the spleen in addition to splenic artery. Another variant vessel bifurcated to enter greater omentum and anterior pole of spleen, as discrete branches. The anatomical vascular variation, if recognized during the imaging work-ups for elective surgical procedures could avoid potential iatrogenic blood loss.
Highlights
The splenic artery being one of the largest branches of the celiac trunk, supplies the structures of the foregut predominantly in the dorsal mesogastrium
One variant vessel, which sprouted as a direct branch from left gastroepiploic artery, entered the anterior pole of spleen in addition to the principal splenic artery located at the hilum of spleen (Fig. 2)
Following another classification proposed by Michels (4), celiac trunk could be classified into 6 types with type 6 having left gastric, splenic, common hepatic and superior mesenteric artery arising from a common trunk
Summary
The splenic artery being one of the largest branches of the celiac trunk, supplies the structures of the foregut predominantly in the dorsal mesogastrium It passes through the lieno-renal ligament and before reaching the hilum of spleen, usually gets divided into superior and inferior polar branches. One variant vessel, which sprouted as a direct branch from left gastroepiploic artery, entered the anterior pole of spleen in addition to the principal splenic artery located at the hilum of spleen (Fig. 2). Another vessel, from the left gastroepiploic artery, continued as a common trunk and got divided into two branches. We couldn’t observe significant abnormalities in other abdominal organs and their vasculature
