[Qualitative ultrasound analysis as a preliminary step in revascularization of the femoro-popliteal axis].

The Authors report on the use of non-invasive techniques in the preliminary evaluation of revascularization of the femoral-popliteal axis. The study of this pathology, for which surgery has become less and less frequent, being limited to the more serious cases, has greatly benefited by the use of H/R echography and of Doppler. These techniques, which remain complementary to angiography, have proved very important and reliable for their capacity to visualize the arterial lumen, an important element for the pre- and post surgical evaluation of vascular recanalization and of the relationship of continuity and continuity with the nearby structures.
