[Functional significance of the left adrenal vein and the gonadal veins].
Owing to the investigation of changeability variants of the left adrenal, anastomosis of the inferior diaphragmatic and ovarian (testicular) veins--tributaries of the human left renal vein, three variants in inflow of the left adrenal vein in comparison to the left ovarian (testicular) vein have been revealed. In the first variant, that occurs in 70% of cases, the left adrenal vein flows into the left renal vein by 15 cm more medially from the ostium of the ovarial (testicular) vein. The second variant occurs in 11%. The left adrenal and ovarian (testicular) ostia are situated at the same level. The distance from the hilus renalis to the place, where the ostia mentioned get into the renal vein, is about 39 mm. In the third variant (19%) the left adrenal vein gets into the left renal vein nearer to the hilus renalis than the ovarian (testicular) veins. An average distance from the hilus renalis to the ostium of the left adrenal vein is 33 mm. The second variant, when the left adrenal vein gets into the left renal vein, contributes to appearance of the primary varicocele at the left. When the operation for nephrectomy is made at the left, our data make it possible to recommend a purposeful ligation of the left renal vein more laterally to the ostium of the ovarian (testicular) vein. In 80% this ligation will not disturb the function of the left adrenal vein.
