Evaluation of renal vascular variations with computed tomography

Abstract Background It is important to know the renal vascular variations before surgeries and invasive procedures. The aim of this study evaluate prevalence types variation arteries veins. Methods abdominal CT images 460 patients, taken between 2019 2021, were retrospectively analyzed in axial coronal planes. presence number accessory early branching main artery evaluated. Then, bilateral vein investigated. Finally, compression left by different anatomical structures was Results Of 450 patients included study, mean age 53 years. No detected 378 on right side (84%) 392 (87.1%). most common an inferior hilar 7.5% 6% rates left, respectively. An polar observed at overall rate 1.3%. superior found 3.3% 2% right, 3.5%. Multiple a 6.4%. Early 4.9% 2.2% left. two three veins 13.1% 0.6%, Retroaortic circumaortic 3.5% 4.4% rates, anterior posterior 4.6% 0.9% Conclusion Considering that are too many underestimate, examination for anatomy planning phase surgery or interventional procedures will be great benefit avoid potential complications.
