Atypical variable origins of the left inferior phrenic artery and left gastric artery

The current report describes the combined unusual origin of the left inferior phrenic and left gastric arteries observed during a routine dissection of the upper abdominal region.

The branches of the abdominal aorta are important vessels that supply blood to various organs and structures in the abdominal cavity. While there is typically a common pattern of branching, anatomical variations can occur, leading to differences in the branching patterns of the abdominal aorta.

An accidental finding in an 80-year-old male cadaver within anatomical dissection was assessed.

We observed that the left inferior phrenic artery originated from the celiac trunk and gives off middle and superior suprarenal arteries, while the left gastric artery arose from the abdominal aorta independently.

The identification of anatomic vascular abnormalities of the abdominal aorta and its branches is clinically important in surgical and invasive arterial procedures and preoperative knowledge of vascular anomalies should prevent iatrogenic vascular trauma and complications during surgery (Fig. 3, Ref. 14).
