Internal iliac vein drains the pelvic viscera, gluteal region, and the perineal region. Knowledge of its variations is of importance to radiologists, gynecologists, and orthopedic surgeons. We found one of the rare variations of the internal iliac vein during our cadaveric dissections. The right internal iliac vein had anterior and posterior trunks. The anterior trunk joined the external iliac vein to form the common iliac vein. The posterior trunk terminated into the common iliac vein. There was a broad communication between anterior and posterior trunks. Further, there were two venous rings formed by the tributaries of the internal iliac veins. One of them surrounded the superior gluteal artery and the other surrounded the internal pudendal and inferior gluteal arteries. Here, we discuss the clinical importance of the case.
髂内静脉引流盆腔脏器、臀区和会阴区的血液。了解其变异情况对放射科医生、妇科医生和骨科医生很重要。我们在尸体解剖过程中发现了髂内静脉一种罕见的变异情况。右侧髂内静脉有前干和后干。前干与髂外静脉汇合形成髂总静脉。后干汇入髂总静脉。前后干之间有广泛的交通。此外，髂内静脉的属支形成了两个静脉环。其中一个围绕臀上动脉，另一个围绕阴部内动脉和臀下动脉。在此，我们讨论该病例的临床意义。
