Abstract：
Obturator vein usually terminates into the internal iliac vein. Its variations are the cause major bleeding problems in pelvic surgeries. We observed a rare variation in the termination of the right obturator vein. There was a duplication of right obturator vein. Both obturator veins entered the pelvic cavity through the obturator foramen and joined with two vesical veins to form a vesico-obturator plexus. This plexus surrounded the internal iliac artery and terminated into the internal iliac vein. Awareness of this rare variation could be of importance to anatomists, radiologists, gynaecologists, urologists, and orthopaedic surgeons. The plexus might lead to hazardous bleeding in pelvic lymph node clearance procedures, hernia surgeries, gynaecological and orthopaedic procedures in this region. The pelvic fractures too can provoke dramatic retroperitoneal hematomas related to these veins injuries.
摘要：
闭孔静脉通常终止于髂内静脉。它的变化是骨盆手术中主要出血问题的原因。我们观察到右闭孔静脉终止的罕见变化。右闭孔静脉重复。两个闭孔静脉通过闭孔进入盆腔，并与两个膀胱静脉相连，形成膀胱闭孔神经丛。该神经丛包围髂内动脉并终止于髂内静脉。意识到这种罕见的变异可能对解剖学家很重要，放射科医生,妇科医生,泌尿科医师,和骨科医生。神经丛可能导致盆腔淋巴结清除手术中的危险出血，疝气手术,该地区的妇科和骨科手术。骨盆骨折也会引起与这些静脉损伤有关的剧烈腹膜后血肿。
