During the dissection of a female human cadaver a case of a duplex ovarian vein was observed. It was unique in its upper course where it anastomosed with an inferior polar renal vein, which in turn was linked to an upper polar renal vein by means of a joining branch. It is hypothesised that this represent a persistent link between the left subcardinal vein and the left sacrocardinal vein, together with some branches of a venous net, which represent the embryological intersubcardinal anastomosis. The gonadal vein arises from the distal (or postrenal) left subcardinal vein portion; the left renal vein develops from the intersubcardinal anastomosis. The venous net derived from the intersubcardinal anastomosis may represent a bypass system in cases of left renal vein occlusion. Left gonadal vein duplicity may also play an important role in the anatomical basis of idiopathic left ovarian vein syndrome or left varicocele, and can lead to mistakes being made during venous sclerotherapy.
在解剖一具女性人体尸体时，观察到一例双支卵巢静脉的情况。其上行段很独特，在此处它与一条肾下极静脉吻合，而这条肾下极静脉又通过一条连接分支与一条肾上极静脉相连。据推测，这代表了左半奇静脉和左骶奇静脉之间的持续连接，以及静脉网的一些分支，这些分支代表胚胎学上的半奇静脉间吻合。性腺静脉起源于远端（或肾后）左半奇静脉部分；左肾静脉由半奇静脉间吻合发育而来。源自半奇静脉间吻合的静脉网在左肾静脉闭塞的情况下可能代表一个旁路系统。左侧性腺静脉双支在特发性左卵巢静脉综合征或左侧精索静脉曲张的解剖学基础中也可能起重要作用，并且可能导致静脉硬化治疗时出现失误。
