Abstract

Background: Testis is drained by the pampiniform plexus of veins which join to form four veins at the superficial inguinal ring, two veins at the deep inguinal ring and one vein at variable levels in the abdomen. The right testicular vein drains into inferior vena cava and left testicular vein drains into the left renal vein. Testicular veins show several variations and they are variations in number; course and termination. The knowledge of anatomic variations of testicular vein will help surgeons and radiologists in recognition of these anomalies and avoid potential complications during surgical procedures.
Materials and Methods: Testicular veins were studied in 25 adult cadavers by dissection method. Two anatomic aspects were considered: Number of testicular veins, and the site of vein termination.
Results and Discussion: In the present study variations in termination and duplication of testicular veins were observed. Right side - One testicular vein occurred in 92% and 2 veins in 4% of the cases. Left side - One testicular vein occurred in 88%, two veins in 8%. Variations of the testicular veins are due to alterations in the embryological origin of the veins.
Conclusion: variations of site of termination and duplication of testicular veins were observed in the present study. These variations are significant surgically and radiological.
Key words: Testicular veins, Anatomic variations, Embryology, Surgical procedures.
