Description
Summary:Renal vascular anatomic variations, especially of the renal arteries, have been observed in about 20-30% of cases, which are very often verified in the left antimere. These variations showed two or three renal arteries stemming directly from the aorta. These anatomic variations have been considered extremely important risk factors in surgical proceedings by different authors. The dissection of a cadaver showed an uncommon venous feature in addition to renal artery variation, specially, in the left antimere. A direct venous communication between left and right kidneys was verified without there being any relation to the inferior cava vein or common iliac veins. Thus, the knowledge of blood vessel anatomic variation is an important element to improve surgical techniques as well as to provide precise analyses of urological and radiological proceedings in different renal diseases. Specially, taking into consideration that hard traction of the renal pedicle could rupture the vessels, leading to lethal hemorrhaging. KEY WORDS: Renal vessels; Anatomic variations; Anatomic dissection. Se han observado variaciones anatomicas vasculares renales, especialmente de las arterias renales, en una frecuencia alrededor del 20 a 30% de los casos, cuya incidencia se verifica a menudo en el antimero izquierdo. En estas variaciones, de acuerdo con lo que se noto, dos o tres arterias renales provenian directamente de la aorta. Distintos autores han considerado que estas variaciones anatomicas son factores de riesgo extremadamente importantes en los procedimientos quirurgicos. En esta investigacion, por medio de la diseccion de un cadaver, se observo una caracteristica venosa rara, ademas de la variacion de la arteria renal, especialmente en el antimero izquierdo. Se verifico una comunicacion venosa directa entre los rinones izquierdo y derecho, pese al hecho que no sea comun cualquier relacion con la vena cava inferior o las venas iliacas comunes. Asi, el conocimiento de la variacion anatomica del vaso sanguineo es un elemento importante para implementar tecnicas quirurgicas, asi como proporcionar analisis exactos de procedimientos urologicos y radiologicos en diversas enfermedades renales, pues se debe considerar ademas que la traccion dura del pediculo renal podria romper los vasos y ocasionar una hemorragia mortal.
