Testicular veins are known to show many variations in their origin, course and termination. Some of their variations can lead to male sterility. We report a unique variation of right testicular vein here. Pampiniform plexus reduced to three testicular veins (medial, middle and lateral) at the deep inguinal ring on the right side. The medial vein terminated into the right renal vein, the middle vein terminated into the inferior vena cava above the level of right renal vein (close to the suprarenal gland) and the lateral vein terminated partly into the veins in the capsules of the kidney and partly into the veins under the diaphragm. The medial and middle testicular veins were connected through an oblique communicating vein. The middle and lateral testicular veins were also connected to each other through another oblique communicating vein. Knowledge of this case could be useful to radiologists, nephrologists and surgeons in general.
已知睾丸静脉在其起源、走行和终止方面存在许多变异。其中一些变异可导致男性不育。我们在此报告一例右侧睾丸静脉的独特变异。在右侧腹股沟深环处，蔓状静脉丛缩减为三条睾丸静脉（内侧、中间和外侧）。内侧静脉汇入右肾静脉，中间静脉在右肾静脉水平上方（靠近肾上腺）汇入下腔静脉，外侧静脉部分汇入肾包膜内的静脉，部分汇入膈下静脉。内侧和中间睾丸静脉通过一条斜行交通静脉相连。中间和外侧睾丸静脉也通过另一条斜行交通静脉相互连接。一般来说，了解该病例对放射科医生、肾病学家和外科医生可能会有所帮助。
