One variation of the obturator artery is aberrant obturator artery (AOA), which is originated from the external iliac artery or the inferior epigastric artery, arching above and behind the superior pubic ramus, descends towards the obturator foramen, completely replacing the irrigation provided by the obturator artery (Baena et al., 2015).
