Measurement of Doppler velocity in diagnosis of peripheral vascular disease in diabetics with peripheral pulse deficit.
Forty-nine diabetics (aged 50-69 yr, with a pulse deficit in 54 legs) were examined for peripheral vascular disease (PVD). In relation to pulse deficits PVD was proved by oscillography in 24 (44%), by qualitative Doppler velocity measurements in 19 (51%) and by quantitative Doppler in 28 (35%) cases. The overall rate of the agreement in the diagnosis between the two Doppler techniques and oscillography was 76.8% and 73.5% respectively. The differences in the PVD frequency detected by Doppler sonography were not significant. However, a comparison of Doppler deficits and pulse deficits showed that PVD was more frequently found by the qualitative Doppler technique (76.0% vs 35.2%, p less than 0.0005). Also in 94.7% of all cases PVD could be detected by the qualitative examination of only one artery. The quantitative Doppler results were directly correlated to localized findings in the foot in PVD. Thus, it can be concluded that in comparison to oscillography the qualitative Doppler velocity measurements are simpler and more time-saving for a screening diagnosis of PVD, while the quantitative technique is useful for evaluating the severity of evident PVD.
