During living donor nephrectomy the renal artery and renal vein are transected as far away from the kidney as possible, to ensure an adequate vessel length for the subsequent transplantation procedure. The arterial supply of the adrenal glands is accomplished by several small vessels (ca. 5-15), while the venous drainage is usually dependent on a single vein. While the right-sided adrenal vein drains directly into the inferior vena cava (IVC), the left-sided adrenal vein drains into the renal vein. Variants are relatively rare and occur in 5% of cases (Sebe P, Surg Radiol Anat 2002). Therefore, during donor nephrectomy of the left kidney the adrenal vein is transected, while this is not necessary on the right side.
