Knowledge of variations of the testicular vessels is essential for urologists, radiologists, and surgeons in general, as iatrogenic injuries of these vessels may affect the spermatogenesis severely. Though variations of testicular vessels are common, combined variations of these vessels are rare. We observed concurrent variations of left testicular vessels in an adult cadaver aged 70 years. There were two gonadal arteries on the left side, both of which arose from the abdominal aorta. The superior one among them hooked around the left renal vein and the left suprarenal veins. There were three testicular veins at the deep inguinal ring, but they formed a plexus of veins at the posterior abdominal wall, which reduced into two veins. These two testicular veins terminated into the left renal vein independently. The deep inguinal ring was congested with the presence of five vessels. This variation could increase the possibility of varicocele.
对于泌尿外科医生、放射科医生及普通外科医生而言，了解睾丸血管的变异情况至关重要，因为这些血管的医源性损伤可能会严重影响精子发生。虽然睾丸血管变异很常见，但这些血管的联合变异却很罕见。我们在一名70岁的成年尸体中观察到左侧睾丸血管的并发变异。左侧有两条性腺动脉，均发自腹主动脉。其中上方的一条绕过左肾静脉和左肾上腺静脉。在腹股沟深环处有三条睾丸静脉，但它们在腹后壁形成了一个静脉丛，然后合并为两条静脉。这两条睾丸静脉分别汇入左肾静脉。腹股沟深环处因有五条血管而充血。这种变异可能会增加精索静脉曲张的可能性。
