Abstract/OtherAbstract:
Three different femoral artery flow velocity parameters in combination with segmental pressure measurements were evaluated for their respective diagnostic value in identifying the presence or absence of hemodynamically significant aorto-iliac disease. A total of 60 patients (119 legs) were examined both non-invasively and with arteriography. Doppler flow velocities were recorded using a 5-MHz CW Doppler velocity metering system. Of the three parameters used (peak velocity, decay time and deceleration), a decay time of 220 ms yielded the most practical discriminant value. The accuracy increases when in addition the upper thigh/arm pressure ratio values are considered. The results indicate that the combination of femoral artery decay time with the upper thigh/arm pressure index provides a simple and accurate non-invasive screening method to confirm or rule out aorto-iliac disease. This helps to determine whether the patient is a candidate for arteriography and for potential surgical intervention.
