Rare combined variations of renal, suprarenal, phrenic and accessory hepatic arteries

Abstract

Knowledge of the morphological variations within the abdominal cavity is significant for all medical practitioners planning surgery. This report presents the rare origin of a common trunk for the right inferior phrenic artery, and superior and inferior suprarenal artery from the right renal artery. An accessory hepatic artery was found, which served as a branch of the right inferior phrenic artery. The diameter of the common trunk was 3.95 mm, and the diameters of the inferior and superior suprarenal arteries were 1.84 and 1.36 mm, respectively. The diameter of the right inferior phrenic artery was 2.55 mm. Both the embryological background and the potential clinical significance of this morphological variation are discussed. Knowledge of this common trunk and the occurrence of the accessory right hepatic artery may be of significance in diagnostic and surgical procedures.
