title: ['Sciatic" artery and vein. Apropos of 3 cases].
abstract: Three cases of sciatic axis are reported: one case, documented by arteriography, of bilateral persistant sciatic artery, which is a rare but well known embryologic abnormality and two cases, documented by varicography, of sciatic vein. Vascular embryology of lower limb is briefly related; the usefulness of arteriography for pulsatile buttock masses and of varicography concerning some leg's varicose veins are developped.
