title: A simple aid in greater saphenous phlebography.
abstract: During the last 32 months, we have used isometric contraction of the muscles of the lower extremities during saphenous phlebography for the purpose of improving the degree of opacification of the greater saphenous vein. Using this technique, acceptable visualization of the greater saphenous system may be obtained with minimal risk in over 90 per cent of the patients.
