Abstract
Anatomical variations of the renal arteries and veins are considered important for surgeons before renal operations, for renal vascular anatomy evaluation to avoid possible complications. The MDCTA is considered an accurate tool in the detection and visualizes normal renal vasculature and their variants, it is considered a fast, dependable, and non-invasive modality.
In this study, we assessed the renal vascular anatomy in 42 patients using MDCTA of the AA for various abdominal problems. For renal arteries, 22 patients out of 41 (53.7%) showed accessory renal arteries. Among those,16 patients had unilateral accessory renal arteries, and 6 patients had bilateral renal arteries. Also, seven patients out of 41 (17.1%) had early renal artery division variants. For renal veins, eight patients out of 41 (19.5%) had supernumerary renal veins, seven patients (17.1%) had retro-aortic renal veins, two patients (2.4%) had circum-aortic renal veins and three patients (7.3%) had late venous confluence renal veins.
