The literature showing information regarding ovarian venous variation, its diameter and termination distance from respective renal venous origin are limited. This information is important in various surgical and clinical procedures including venous embolization, vascular reconstruction during renal transplantation and localizing the source of origin of a pelvic mass. We examined 94 sides of 47 formalin fixed female cadavers and noted the course and termination of ovarian veins. We measured the diameter of ovarian veins at their termination point and the termination distance in respect to the termination point of renal veins at inferior vena cava (IVC) on respective sides. We found two cases of variations related to right ovarian vein -one, right ovarian vein joined the right renal vein; two, right ovarian vein duplicated and joined with IVC at two different points. We found one case of variation related to left ovarian vein-a partially duplicated left ovarian vein. All the variations were unilateral. The mean diameters of right and left ovarian veins were 3.66±1.18 and 4.20±0.96 mm, respectively. The distance of termination of ovarian veins ranged from 19-40 mm and 13-41 mm, respectively from termination points of right and left renal veins at IVC on respective sides. Our study presents a set of data regarding variation of ovarian veins, diameters and termination distances which could be useful for gynecologists, surgeons and radiologists.
关于卵巢静脉变异、其直径以及距各自肾静脉起始处的终止距离的文献资料有限。这些信息在包括静脉栓塞、肾移植期间的血管重建以及盆腔肿块起源部位定位等各种外科和临床操作中都很重要。我们检查了47具福尔马林固定的女性尸体的94侧卵巢静脉，记录了其走行和终止情况。我们测量了卵巢静脉在其终止点处的直径以及相对于下腔静脉（IVC）上各自侧肾静脉终止点的终止距离。我们发现了两例与右侧卵巢静脉有关的变异情况——其一，右侧卵巢静脉汇入右侧肾静脉；其二，右侧卵巢静脉重复并在两个不同点汇入下腔静脉。我们发现了一例与左侧卵巢静脉有关的变异情况——左侧卵巢静脉部分重复。所有变异均为单侧性。右侧和左侧卵巢静脉的平均直径分别为3.66±1.18毫米和4.20±0.96毫米。卵巢静脉的终止距离分别距下腔静脉上各自侧右肾静脉和左肾静脉的终止点19 - 40毫米和13 - 41毫米。我们的研究提供了一组关于卵巢静脉变异、直径和终止距离的数据，这可能对妇科医生、外科医生和放射科医生有用。
