WebPatient supine. Locate the anterior tibial vessels by placing the probe transversely over the antero-lateral distal leg supeior to the ankle. Rotate into longitudinal and examine with colour/spectral doppler, predominantly to confirm patency. If the velocity is less than 15cm/sec, this indicates diminished flow.

We have included two analyses. Our main analysis includes occlusion in the “greater than” groups so that it is those that have no flow or a PSV equal to or greater than a specific velocity (eg, no flow or a PSV 285 cm/s for 60% RAS). Another analysis is included where the occlu-sions were excluded.
