From the Research
The provided arterial velocities appear to be within normal ranges, suggesting adequate arterial flow without significant stenosis. For lower extremity arterial Doppler ultrasound, normal peak systolic velocities typically range from 50-120 cm/s in the common femoral artery, 50-100 cm/s in the superficial femoral artery, 40-80 cm/s in the popliteal artery, and 30-60 cm/s in the tibial arteries (including posterior tibial and dorsalis pedis arteries) 1. The values presented (CFA 51.1 cm/s, proximal SFA 55 cm/s, distal SFA 34.3 cm/s, popliteal 35 cm/s) generally fall within these expected ranges, though the distal SFA and popliteal values are at the lower end of normal. Significant stenosis would typically show velocities exceeding 200-250 cm/s at the stenotic site with post-stenotic turbulence and velocity reduction. The reference to "visualiza 35" is unclear but may refer to a visualization score or previous measurement. These findings suggest adequate arterial flow without significant stenosis, though clinical correlation is always necessary as mild disease may be present with borderline-low velocities in the distal vessels. According to a recent study, Doppler ultrasound has been shown to be a reliable diagnostic tool for peripheral artery disease, with high sensitivity and specificity for detecting stenosis in the iliac, femoral, and popliteal sectors 1. Therefore, based on the most recent and highest quality evidence, the provided arterial velocities can be considered within normal limits, and no further intervention is necessary at this time.
