Background: Transcatheter arterial chemoembolization is a common treatment for patients with inoperable hepatocellular carcinoma If the carcinoma is advanced or the main arterial supply, the hepatic artery, is occluded, extrahepatic collateral arteries may develop Both, right and left inferior phrenic arteries (RIPA and LIPA) are the most frequent and important among these collaterals However, the topographic anatomy of these arteries has not been described in detail in anatomy textbooks, atlases and most previous reports Aims: To investigate the anatomy and branching patterns of RIPA and LIPA on cadavers and compare our results with the literature Study Design: Descriptive study METHODS: We bilaterally dissected 24 male and 2 female cadavers aged between 49 and 88 years for this study RESULTS: The RIPA and LIPA originated as a common trunk in 5 cadavers The RIPA originated from the abdominal aorta in 13 sides, the renal artery in 2 sides, the coeliac trunk in 1 side and the left gastric artery in 1 side The LIPA originated from the abdominal aorta in 9 sides and the coeliac trunk in 6 sides In 6 cadavers, the ascending and posterior branches of the LIPA had different sources of origin CONCLUSION: As both the RIPA and LIPA represent the half of all extrahepatic arterial collaterals to hepatocellular carcinomas, their anatomy gains importance not only for anatomists but interventional radiologists as well
