Abstract

Knowledge of the anatomical variations of the visceral branches of the abdominal aorta is important information for planning any surgeries in the region. We present here a rare constellation of variations of visceral vessels around the kidneys with a brief review of the recent literature. On the right side, an accessory renal artery was observed originating just distal to the main renal artery. The middle suprarenal artery was absent on the right side and there were two inferior suprarenal arteries originating from a branch of the main right renal artery. On the left side, the testicular artery had an arched course anterior to the left renal vein mimicking an unusual variety of nutcracker phenomenon. The right kidney was drained by two renal veins into the inferior vena cava. Knowledge of the coexistence of such complex anatomical variations might be helpful for clinicians during diagnostic and therapeutic procedures.

Resumo

O conhecimento das variações anatômicas dos ramos viscerais da aorta abdominal é uma informação importante para o planejamento de qualquer cirurgia nessa região. Neste relato, apresentamos um raro conjunto de variações de vasos viscerais ao redor dos rins, bem como uma breve revisão da literatura recente. No lado direito, foi observada uma artéria renal acessória originando-se distal à artéria renal principal. Não havia artéria suprarrenal média no lado direito, e havia duas artérias suprarrenais inferiores originando-se de um ramo da artéria renal direita. No lado esquerdo, a artéria testicular apresentava um curso arqueado anterior à veia renal esquerda, simulando uma variedade incomum do fenômeno do quebra-nozes. O rim direito era drenado por duas veias renais para a veia cava inferior. O conhecimento da coexistência de tais variações anatômicas complexas pode ser útil para os clínicos durante os procedimentos diagnósticos e terapêuticos.
