| Abstract | |
During the puerperium period there is a high incidence of reproductive diseases resulting in increased calving interval and decrease in conception rate. The endometritis is a postpartum disease that is characterized by a superficial inflammation of endometrium. With the aim to obtain new non-invasive and accurate diagnostic tools, that provide early results in reproduction, it is possible to be used the conventional ultrasound associated to Doppler that provides real time information about vascular architecture and hemodynamic aspects of vessels in several organs. This study aims to describe, through Doppler ultrasound, hemodynamic changes in the uterus of cows caused by endometritis. Were evaluated the female reproductive tract of 89 Holstein cows between 25 to 35 days postpartum using vaginoscopy, conventional ultrasound and Doppler, as well as cytology and microbiological examination. From the 89 animals that were studied, 33 were healthy (control) and 56 with endometritis diagnosed by cytology (healthy <10% polymorphonuclear). The obtained results show that animals with endometritis had increase in cervix (p = 0.04) and the uterus represented by left uterine horn (p = 0.02). However, it was not detected difference when compared the body condition score (BCS). About the ultrasound was noted that animals with intrauterine fluid (IUF) and intrauterine heterogeneous content (IUHC) had endometritis (p <0.0001) correlation with the presence of Trueperella pyogenes and yeasts. With the color Doppler mode it was possible to obtain the vascularization of mesometrium (p = 0.004) and endometrium (p = 0.025) associated with endometritis. However, it was not observed statistical difference in the measurements of the spectral Doppler (resistance index, pulsatility and blood flow). Therefore, the search for new techniques, less invasive and fast result, as the Doppler ultrasound can provide satisfactory answers as the evolution of uterine changes and thereby associate the results to the reproductive precocity.
