Abstract

“Variability is the law of life” Sir William Osler – Father of modern medicine. The aim is to illustrate the variation in the branching pattern of the celiac trunk. The study was conducted in the Department of Anatomy, Kamineni Institute of medical sciences Narketpally, Nalgonda Dt. Andhra Pradesh, India. A case of unusual origin of Inferior phrenic arteries from the celiac trunk in addition to its usual left gastric, splenic and common hepatic arteries were recorded. The pattern of the branching of the celiac trunk was observed to vary from classical trifurcation to an abnormal pentafurcation. This type of rare variation has significant importance in surgical and radiological procedures. Knowledge of variations of the celiac trunk is important as to do an appropriate vascular ligation and anastomosis.

Highlights

The celiac trunk (CT) takes origin from the antero-lateral surface of the abdominal aorta
We described an unusual branching pattern of the celiac trunk (Figure 1) during routine educational dissection of a 50-years-old male cadaver
We found origin of the left inferior phrenic artery and right inferior phrenic artery from the celiac trunk (Figure 2) directly

Summary

Introduction

The celiac trunk (CT) takes origin from the antero-lateral surface of the abdominal aorta. There were five branches, including three classic branches of CT. The left phrenic artery (LPA), right phrenic artery (RPA) was the first two branches of the CT. The remaining three branches were left gastric artery (LGA), splenic artery (SA), and common hepatic artery (CHA). The classic description of normal celiac trunk anatomy is that the main trunk trifurcates into the left gastric, splenic and common hepatic arteries, additional branches of the coeliac trunk other than its usual branches are referred to as collaterals. We found Inferior phrenic arteries as collateral branches
