Abstract

The suprarenal glands possess a complex arterial supply that is critical to their physiological function and surgical management. Typically, each gland receives blood from the superior, middle, and inferior suprarenal arteries, although considerable anatomical variation exists in the origins and distribution of these vessels. Recognition of such variations is particularly important during abdominal and retroperitoneal procedures, where unanticipated vascular anatomy may complicate surgical dissection and compromise glandular perfusion. This case report describes an anomalous artery supplying the left suprarenal gland that coursed medially across the posterior abdomen, in the absence of a middle suprarenal artery arising directly from the abdominal aorta. Further anatomical examination revealed that this vessel originated from the left gastroepiploic artery. To our knowledge, this represents the first reported case of a suprarenal artery arising from a gastric vessel. This finding expands the recognized spectrum of suprarenal arterial anatomy and highlights the clinical importance of identifying atypical vascular origins and courses to support appropriate surgical planning and minimize the risk of inadvertent vascular injury.
