Left Gonadal Vein

Our study on 51 cases was performed by dissection and injection of plastic mass followed by corrosion with NaOH, on formalinized human cadavers and on organic blocks aorta-inferior vena cava-right and left kidneys. The trajectory of the gonadal veins was in all cases rectilinear, in 47.06% of cases being oriented supero-medially, and in 52.04% of cases being vertical. At the termination the gonadal vein made with the corresponding renal vein an open lateral angle ranging between 37-900. The termination of the gonadal vein in the renal vein was most frequently on its postero-inferior surface, an aspect encountered in 54.90% of cases. The gonadal vein ended in the renal vein closer to the aorta (56.86% of cases). Compared to the termination of the left inferior adrenal vein, the gonadal vein ended laterally from it in 58.82% of cases, in 33.33% of cases ending at the same level as it, and in 4 cases (7.84% of cases) it ended laterally from the inferior adrenal vein. The caliber of the gonadal vein at the termination in the renal vein was found to be between 1.3-3.2 mm, the average being 2.04 mm. The present study examines the morphological features of the left gonadal veins, providing insights into the increased prevalence of varicocele on the left side. Anatomical knowledge of testicular vein variations and their spatial relationships with neighboring vessels is crucial for urologists and vascular surgeons, as it aids in the accurate diagnosis of urogenital conditions and helps prevent complications during retroperitoneal surgeries and imaging procedures.
