ABSTRACT
In clinical Anatomy, the renal venous system is relatively understudied compared to the arterial system. The present study reports the presence of an Additional renal vein on the right side draining directly into the Inferior venacava and pre hilar primary tributaries of the left renal vein .The above findings were observed in a male cadaver during routine dissection of abdomen for undergraduate students in the Department of Anatomy,Rajarajeswari Medical college and hospital, Bengaluru, Karnataka India. The Anatomical knowledge of renal veins and its variations are of extreme importance for the surgeon who approaches the retroperitoneal region mainly in the face of current frequency of Renal transplant surgeries.Knowledge of Anatomy and Anomalies of Renal veins is necessary for retroperitoneal surgery and venographic procedures in addition to providing safety guidelines for endovascular procedures. In view of immense clinical significance attached to the variations in the renal vascular patterns, the present case has been discussed with emphasis to its embryological basis.
