Objective- Obtaining the normal images of color doppler and estimation of blood flow velocity parameters of femoral and axillary arteries in dog. Design- Descriptive studyAnimals- ۷ healthy adult mixed-breed dogs, weighing ۱۴.۳ ± ۲.۸ kg (mean ± SD). Proceudure- Left and right femoral and axillary arteries of hind and forelimbs were evaluated. Color and spectral doppler images of the artery were obtained. Values of peak systolic velocity, end-diastolic velocity, mean velocity, resistive index and pulsatility index were measured. Statistical analysis- Calculation of mean and standard deviation of measured parameters using Microsoft excel ۲۰۰۳. Results- Color Doppler of both arteries showed a laminar flow with higher velocity in the center of flow. High-resistance flow pattern with triphasic flow velocity and plug velocity profile were observed in spectral waveform analysis of pulsed Doppler. Conclusion and Clinical Relevance- Results of this study can be useful for hemodynamic evaluation of femoral and axillary arteries diseases such as thromboembolism and arterial stenosis in dogs.
