Abstract

The present study investigates prospectively the validity and accuracy of the simplified Bernoulli equation in the duplex-derived determination of pressure gradients across iliac artery stenoses in patients with occlusive artery disease. In 28 patients (age range, 38 to 76 years; mean, 53 years) with short iliac artery stenoses, we obtained both duplex scan stenotic jet velocity and catheter pressure measurements. Mean and maximum pressure gradients were determined by both methods, aswas the peak-to-peak catheter gradient. The correlation between the duplex-determined and nonsimultaneously measured catheter mean pressuregradients was r = 0.77 (standard error of the estimate [SEE] = 5 mm Hg), that between the duplex-derived and catheter-determined maximum pressure gradients was r = 0.80 (SEE = 10 mm Hg), and that between maximum duplex-determined and peak-to-peak catheter gradient was r = 0.76 (SEE = 12 mm Hg). The peak-to-peak catheter gradient was significantly lower than the maximum duplex-derived gradient (46 versus 53 mm Hg, P < 0.05). Duplex-determined mean pressure gradient decreased from 15 +/- 6 to 3 +/- 1 mm Hg after balloon angioplasty of the iliac stenoses. Duplex scan can be used to predict pressure gradients across short iliac artery stenoses, provided that errors caused by angle malcompensation are prevented.
