A rare case of unconnection between the celiac trunk and the abdominal aorta and a large anastomosis with the inferior mesenteric artery with a literature review.

Purpose: Direct connection between the celiac trunk (CT) and inferior mesenteric artery (IMA) is very rare, knowledge of this anomaly is of great importance to surgeons and anatomists.

Introduction: Splanchnic arteries arise from the abdominal aorta (AA). Unusual development of these arteries can lead to considerable variations. Historically there were a lot of classification of the variation in the CT and IMA, none of the classifications describes a direct connection from IMA to CT.

Materials And Methods: We report a rare case in which the connection between the CT and AA was lost and replaced by a direct anastomosis with IMA.

Results: 60 year old male presented to the hospital to undergo a computed tomography scan. Which showed that there was no CT arising from the AA, but there was a large anastomosis arises from the IMA and ended with a short axis and Left gastric artery (LGA), Splenic artery (SA), Common hepatic artery (CHA) arise from this axis, these arteries continued to the stomach and spleen and liver normally. The anastomosis provides the total supply to the CT. The CT branches are normal.

Conclusion: Knowledge of the arterial anomalies provides an important help in clinical surgical implications especially in organs transplant.
