Introduction: The inferior phrenic arteries constitute a pair of important vessels supplying mainly diaphragm and multiple organs like adrenal glands, esophagus, stomach, liver, inferior vena cava and retro peritoneum. Other sources of origin of IPA are renal, supra renal, hepatic, left gastric or superio mesenteric arteries in 8% of the cases. A detailed knowledge of IPA with its variations is very helpful for interventional radiologists (chemoembolization), oncologists (hepatic tumors) and surgeons Aim: Study of origin of inferior phrenic artery from coeliac trunk with its incidence. Study the unusual course of inferior phrenic artery arising from coeliac trunk and compare with similar studies done. To study on development of inferior phrenic artery. Material and methods: This study was conducted in our Institute from 2014 to February 2017. Thirty four formalin fixed cadavers (21male, 13female) aged 30 to 70 years having 68(34 right and 34 left) inferior phrenic arteries were studied. Results: Out of 34 cadavers studied the inferior phrenic arteries arose from coeliac trunk in 16(47%) cadavers and in the remaining 18(52.9%) cadavers IPA arose normally from abdominal aorta. The incidence of origin of RIPA from coeliac trunk is 14.7% and from LIPA from coeliac trunk is 38.2% indicating LIPA has more predispositions arising from celiac trunk when compared to RIPA. Conclusion: Study on inferior phrenic artery is useful for clinicians, anatomists, researchers, surgeons and oncologists during nephrectomy and adrenal lesions.
