“…It has been reported that in 17% and 22% renal arteries originated from the level of L1-L2 intervertebral disc on the right side and in 23% and 22% renal arteries originated from the level of L1-L2 intervertebral disc on the left side. 10,15 These findings in this study could be considered as moderate.…”

Purpose: Renal artery variations are important for clinical reasons. The aim of this study is to determine the originating level and variations of renal arteries with 64-channel multidetector computed tomography (MDCT). Materials and methods: In a university hospital, 820 patients who underwent MDCT angiography of the abdominal aorta were retrospectively evaluated. The number, early division (ED), and originating level of renal artery were evaluated retrospectively. Variations of the renal artery on both sides, the difference between the genders with variations of the renal artery, were compared with chi-square test. Results: Renal artery originating from the level of L1-L2 intervertebral disc was found in 37.0% and 38.9% of patients on the right and left sides, respectively. Renal artery variations, including extrarenal artery (ERA), were found in 27% and ED in 26.7% of the patients. Significant differences were found in ED and ERA prevalence for genders (p = 0.006 and p = 0.043, respectively). The prevalence of both variations is higher in males. Conclusions: An awareness of renal vascular variations is very important for both surgeons and radiologists. In this series, renal arterial variations were found in approximately one-fourth of the study population.

“…Previous anatomic, conventional angiographic and CT angiographic reports concerning the renal artery have been typically morphometric studies and have usually investigated the prevalence of an aRA (1,10,15,16). The prevalence of an aRA has been generally accepted to be approximately 25-30% in different study series (1-4, 7).…”

OBJETIVO: Verificar a prevalência e a distribuição das artérias renais e de seus ramos in vivo, relacionando as particularidades encontradas nas artérias renais com o sexo e sua lateralidade. MÉTODO: Duzentos pedículos renais foram estudados por meio de angiotomografias e suas artérias analisadas de acordo com número, posição de origem, calibre, comprimento e trajeto em relação aos segmentos renais. Sua frequência e lateralidade foram pesquisadas quanto ao sexo e idade. RESULTADOS: Foram observadas múltiplas artérias em 61,5% dos pedículos (56% à direita e 67% à esquerda), ocorrendo em 65% dos homens e 58% das mulheres. A origem aórtica para as múltiplas artérias foi mais frequente à direita e, com maior frequência, as artérias renais se originaram entre as vértebras L1 e L2 como divisões pré-hilares da artéria principal. O comprimento médio da artéria principal foi maior em rins direitos com artéria única. Não houve diferença entre o diâmetro da artéria renal principal. CONCLUSÃO: Existe maior prevalência das múltiplas artérias renais do que aquela descrita na literatura, sem diferença entre os sexos ou lateralidade. As artérias renais originaram-se com maior frequência entre as vértebras L1 e L2, como divisões pré-hilares da artéria principal e com trajeto ao hilo do rim. O comprimento médio da artéria principal é maior à direita e nos rins com artéria única. Não houve diferença no diâmetro da artéria renal principal entre rins com artérias únicas e múltiplas.
