El conocimiento de la anatomía venosa del riñón y sus variaciones es esencial para realizar cualquier tipo de procedimiento en la región. Se reporta una variante del árbol venoso del riñón izquierdo, encontrado durante la disección cadavérica, la vena renal izquierda retro-aórtica. Se trató de un tronco único originado a nivel del hilio renal izquierdo que discurrió por detrás de la arteria aorta abdominal para finalizar en la vena cava inferior. La existencia de este vaso se asocia a la embriología de la vena cava inferior. Se discuten aspectos quirúrgicos, radiológicos y embriológicos de su persistencia. Otras implicancias clínicas también son comentadas.
Understanding of the renal venous anatomy and its variations is essential to perform any procedure in the region. We report a variation of the left renal venous tree found during a cadaveric dissection, the retro-aortic left renal vein. It was a unique venous trunk that emerged from the left renal hilum and traveled dorsally to the abdominal aorta before reaching the inferior vena cava. The existence of this vessel is associated to the embryology of the inferior vena cava. We discuss the surgical, radiological and possible embryological aspects. Other clinical implications are also considered.
