Aim: The knowledge of arterial anatomical variation is important for surgical and radiological diagnoses. Objective: Inferior phrenic arteries which supply the diaphragm are known to have variation in their origin. With the available literature which has been reviewed, the present study intends to verify these variations. Methods: 24 adult human cadavers preserved in 10% formalin were obtained from department of Anatomy, Hassan Institute of Medical Sciences, Hassan was dissected and origin of IPA was studied. Result: IPA has its usual origin from abdominal aorta in 20 cases. In 2 cases they were arising from the celiac trunk, LIPA from left gastric artery in 1 case and RIPA from the celiac trunk in 1 case. Conclusion: The knowledge of variation in anatomical arterial structure are important in abdominal operations to avoid unintentional damage or sectioning of small caliber arteries and during invasive arterial procedures.
