Visualization of the plantar arch by aortography: technique and value.

Arteriograms of the feet in 100 consecutive, routine aortograms in patients with leg ischaemia were analysed to assess the frequency with which the plantar arch was visualized. The technique used involved a long injection time, a large volume of contrast medium and slow filming. The plantar arch was demonstrated in 75% of feet, shown to be occluded in 12% and not demonstrated for technical reasons in 13%. The importance of the integrity or otherwise of the plantar arch is emphasized in assessing patients for distal bypass grafts. It is recommended that an attempt be made to demonstrate the plantar arch in all patients undergoing aortography for ischaemia of the legs.
