Abstract
We present a case with accessory pre-segmental arteries and micro-kidneys. There are no articles on the effects of the accessory pre-segmental renal artery on the size of the kidney. Therefore this study aimed to investigate whether a relationship exists between the accessory arteries and kidney size. Left pre-segmental artery variations and bilateral microkidneys were detected in a 62-year-old female cadaver during routine retroperitoneal dissection. The right micro kidney was 7.74 cm in length, 3.82 cm in width and 3.87 cm in thickness, and the left micro kidney was 6.82 cm in length, 3.42 cm in width and 3.02 cm in thickness. The superior left pre-segmental artery L1 at the origin site of the left renal artery and just below the superior mesenteric artery was 8.98 cm in length, 0.54 cm in width and 0.42 cm in thickness, and the inferior left pre-segmental artery L1-L2 at the origin site of the left renal artery was 8.92 cm in length, 0.54 cm in width and 0.41 cm in thickness. The presence of the accessory pre-segmental artery might provide clues regarding the presence of an abnormality of the kidney. Therefore, surgeons should know pre-segmental artery variations and associated kidney size abnormalities.
