Abstract

A sound knowledge of variations in the branching pattern of the abdominal aorta is crucial for operative, diagnostic, and endovascular procedures. We report a unilateral anomalous lateral branch of the abdominal aorta observed during dissection classes.This anomalous branch took origin from the anterior surface of the abdominal aorta behind the left renal vein and pierced the left renal vein. After piercing the left renal vein, it traced a tortuous course through the peri-renal fat pad in front of the lower part of the left kidney. The artery then ran downward and laterally, pierced the anterior layer of thoracolumbar fascia, and continued to the posterior abdominal wall to supply its muscles. It also supplied the fat and fasciae around the kidney. Such an anomalous lateral branch could bleed significantly during renal surgery. It could also mislead radiologists during the invasive radiologic procedures.

Resumo

Um conhecimento sólido das variações no padrão de ramificação da aorta abdominal é crucial para procedimentos cirúrgicos, diagnósticos e endovasculares. Relatamos um ramo lateral anômalo unilateral da aorta abdominal observado durante as aulas de dissecção. O ramo teve origem na superfície anterior da aorta abdominal, atrás da veia renal esquerda, e perfurou a veia renal esquerda. Após perfurar a veia renal esquerda, seguiu um trajeto tortuoso através da camada de gordura perirrenal em frente à parte inferior do rim esquerdo. A artéria corria para baixo e lateralmente; perfurou a camada anterior da fáscia toracolombar e continuou até a parede abdominal posterior para suprir seus músculos. Também supria a gordura e as fáscias ao redor do rim. O ramo lateral anômalo pode sangrar significativamente durante cirurgias renais. Também pode induzir os radiologistas ao erro durante procedimentos radiológicos invasivos.
