Why the study?
Does on-line analysis of the femoral artery flow velocity waveform provide an objective assessment of arterial disease in the leg?
Does on-line analysis of the femoral artery flow velocity waveform provide an objective assessment of arterial disease in the leg?
On-line analysis of femoral artery flow velocity waveforms using specific indices and principal component analysis provides an objective method for assessing lower extremity arterial disease.
May support objective on-line femoral flow assessment in leg arterial disease; leaves open prospective validation before adoption.
Analysis of the instantaneous peak velocity waveform obtained from the common femoral artery can be used to provide an objective assessment of arterial disease in the leg. The calculation of waveform indices pulsatility index and rise time together with principal component analysis has been found to be the ideal method by which to assess the flow data on-line.
