Multiple venous variations at the abdominopelvic region: a case report

Knowledge of vascular variations of the abdominopelvic junction is of importance to surgeons, radiologists, orthopaedic surgeons and other medical disciplines. We report a rare combination of venous variations observed at the abdominopelvic junction of an adult male cadaver. The right common iliac vein was absent. The inferior vena cava was formed by the union of the right external iliac vein and the left common iliac vein. The right internal iliac vein was a tributary of the left common iliac vein. The left common iliac vein was larger than usual in size and its wall was adhered to the right common iliac artery. We discuss the functional, developmental and clinical issues related to the case.
