A Unilateral Accessory Obturator Vessels Variations; Case Report and Literature Review

The presence of an accessory obturator artery was described in May literature; this variant has clinical implications in surgical operations and interventional radiology.During a routine dissection of the deep structures in the pelvic region of a 60-year-old male cadaver in the laboratory of the Department of Anatomy at the National University in Khartoum, Sudan, anatomical variation was discovered on the right side of the pelvic wall: an accessory artery and vein were traversing the right obturator canal.The right accessory obturator artery emerges from the right inferior epigastric artery and descends to join the main right obturater artery; also, the associated right accessory vein was terminated into the right obturator vein.The obturator vessels exhibited a normal path of origin.Awareness of such variations is critical when performing surgical procedures.
