Determinação das medidas dopplerfluxométricas da artéria mediana em equinos

Abstract

Considering the importance of equine culture for the northeast region, the objective was to determine the Doppler flow measurements of the median artery in horses. The analyzes were performed at Horse Training Centers and at the Veterinary Hospital - CCA / UFPB, in Areia, Paraíba State. Fourteen animals were used and trichotomized at the time of the third metacarpal bone, medial face of both thoracic limbs. The sonoscape S2V ultrasound machine with color Doppler coupled to a 7 MHz linear probe was placed at the height of the median artery, in which B was measured. Then, the Color Doppler mode was used to determine the Doppler flow measurements. Thus, with a 95% confidence interval, the B mode values were 0.509 ± 0.133 of the median artery diameter and the Doppler mode 2.198 ± 1.451 of the pulsatility index and 0.980 of the median resistivity index (non-parametric data). as reference values for normality of median artery vascularization. It is concluded that more studies need to be developed to certify the reliability of these values, besides, they can help in the early diagnosis of laminitis and other foot diseases, improving the prognosis of these animals.
