Colour-flow M-mode ultrasonography in three dimensions (two
spatial, one temporal) was used to assess the effects of
intermittent pneumatic compression on the blood flow velocities
in the common femoral vein and artery. The linear array of a
standard 3-D system was held in place over the vessels, to record
while a calf and thigh cuff compressed to 60 mmHg. The data
was reconstructed in 3-D and, subsequently, sliced in different
planes. The technique effectively demonstrated the emptying of
distal veins during compression, and hyperaemia in the artery on
deflation, in the coronal and sagittal planes. Reconstructions of
this type may be of use in visualising the distribution of flow
changes within blood vessels.
