ABSTRACT

 

Vieira LC, Rajão MD, Nogueira K, Da Silva Leite C, Da Cunha Barreto-Vianna AR, De Lima EM., Doppler parameters of lateral digital palmar artery in endurance horses, Onl J Vet Res., 20(12):742-748, 2016. Doppler ultrasound imaging allows for non-invasive low cost mapping of peripheral circulations between vascular and hemodynamic spectral tracings in healthy horses or those with inflammatory disease. We report doppler ultrasound for vascular diameter, average velocity of blood flow, spectral wave, peak-systolic maximum velocity and end-diastolic minimum velocity, resistivity and pulse indexes in palmar digital arteries of forelimbs of purebred arabian horses subjected to equestrian endurance tests. Six foals had never undergone physical training and 6 were athletic horses with a history of participation in equestrian endurance races over 120-160km. We find that vascular aspects remained constant in both groups. It is believed that doppler ultrasound could detect feet forward diseases with high specificity and sensitivity of the method. However, in this study there was no correlation with exercise.
