Anomalous drainage of the right gonadal vein

AbstractThe present research aims to present and describe an unusual and rare anatomical variation in relation to the drainage of the right gonadal vein. This anatomical knowledge is crucial as it assists in the work of surgeons and health professionals in general. The dissection occurred in the anterior wall of the abdomen and, through observational analysis, an anatomical variation was found in the drainage of the right gonadal vein in a human cadaver, obtained by anonymous donation, male gender and without predetermined clinical characteristics, ethnicity, and age, belonging to the Padre Albino University Center collection. This research was approved by the Research Ethics Committee under protocol 12923919.8.0000.5430. The drainage of right gonadal vein is this variant occurs anastomosed with an innominate venous trunk that empties into the inferior vena cava. Furthermore, the presence of an accessory right renal vein is also noticed, which anastomoses with the innominate venous trunk and with the right renal vein, through a vein suggestively called interrenal, differing from the anatomical normality described in the literature. This variation is supposed to occur due to flaws in the development of the embryo, which generate venous changes in the origins of the right gonadal vein. Acknowledging the existence of it is relevant when performing surgical procedures in the region, as it differs from the most frequent anatomy found in the human population. The rare drainage of t...
