%X 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.
