Abstract

The renal arteries arise from the lateral side of the abdominal aorta at the L2 vertebral level, just below the origin of the superior mesenteric artery. Multiple aberrant renal arteries can pose difficulties in renal transplantation, interventional radiological and urological procedures, renal artery embolization, angioplasty, or vascular reconstruction for congenital and acquired lesions. We present a case of a left kidney supplied by the left renal artery along with superior and inferior polar arteries, arising from the aorta and inferior mesenteric artery respectively. The inferior mesenteric artery was crossed by the left ureter and inferior mesenteric vein. The superior polar artery gave rise to an inferior suprarenal artery making the variation important for clinicians and surgeons.

Keywords

renal artery; polar artery; inferior suprarenal artery; ureter; inferior mesenteric vein

Resumo

As artérias renais originam-se do lado lateral da aorta abdominal, no nível da vértebra L2, logo abaixo da origem da artéria mesentérica superior. A presença de múltiplas artérias renais aberrantes pode representar dificuldades para transplante renal, procedimentos radiológicos e urológicos intervencionistas, embolização da artéria renal, angioplastia e reconstrução vascular para lesões congênitas e adquiridas. Apresentamos um caso de rim esquerdo vascularizado pela artéria renal esquerda e pelas artérias polares superior e inferior, as quais se originavam da aorta e da artéria mesentérica inferior, respectivamente. A artéria mesentérica inferior era cruzada pelo ureter esquerdo e pela veia mesentérica inferior. A artéria polar superior dava origem à artéria suprarrenal inferior, o que torna essa variação importante para clínicos e cirurgiões.

Palavras-chave
