An adequate knowledge of anomalies of gonadal veins will help the radiologists and surgeons in recognition and protection of these veins which play major roles in thermo-regulation that is essential for the efficient functioning of testis on which the survival of the human species depends.
The aim of this work is to present an analysis of the anatomical variations of gonadal veins. An effort has also been made to explicate the possible embryological model of development of such variants and to present the variable clinical aspects concerning them.
Gonadal veins in 60 dissection room cadavers were examined for variations from the classic anatomic description.
In the present study, out of 60 cases, male: female ratio was 2:1(40:20) in which no variation was found in ovarian veins. In the 18 (45%) cases, testicular veins showed variations which consist of duplication and atypical drainage.
Variations of drainage of gonadal vein are due to error of embryological development in venous shift and alteration in anastomotic channel of post-cardinal, supra-cardinal and sub cardinal veins.
The gonadal veins present numeric variations as well as variations in its site of drainage, which attributed to the various pathological conditions as varicocele and pelvic congestion syndrome, leading to infertility in patients. Hence, in -depth knowledge of these developmental anomalies of gonadal veins is important.
充分了解性腺静脉的异常情况将有助于放射科医生和外科医生识别和保护这些静脉，它们在体温调节中起着重要作用，而体温调节对于睾丸的有效功能至关重要，人类的生存依赖于睾丸的正常功能。
本研究旨在分析性腺静脉的解剖变异。同时，还努力阐明这些变异可能的胚胎发育模型，并介绍与之相关的不同临床情况。
对60具解剖室尸体的性腺静脉进行检查，以观察其与经典解剖描述的差异。
在本研究的60例中，男女比例为2:1（40:20），其中卵巢静脉未发现变异。在18例（45%）中，睾丸静脉出现变异，包括重复和非典型引流。
性腺静脉引流的变异是由于胚胎发育过程中静脉移位的错误以及后主静脉、上主静脉和下主静脉吻合通道的改变。
性腺静脉存在数量变异以及引流部位的变异，这与精索静脉曲张和盆腔充血综合征等各种病理状况有关，可导致患者不孕。因此，深入了解性腺静脉的这些发育异常很重要。
