“…They present both an intermediate resistivity pattern when compared to animals without changes and a reduction in RI to values between 0.7 and 0.8 (Figure 1A), which helps in the patients' diagnosis (Batista et al, 2016;Veiga et al, 2017). In cases where signs of infections appear (Figure 2), the demand of metabolites and oxygen increases, and the presence of vasodilation cytokines causes a decrease in the distal vascular tone (Carvalho et al, 2008;Veiga, 2012;Holen, Research, Society and Development, v. 10, n. 5, e52610515352, 2021 (CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v10i5.15352 6 2014). The metabolic changes are reflected in both the ultrasound spectrum, and change in the hemodynamic pattern to high speed and low resistance with RI ranging from 0.6 to 0.7 -Figure 1B (Batista et al, 2015;Lacerda, 2015;Veiga et al, 2017).…”

Given the importance of the reproduction field combined with the use of the Pulsed-Wave (PW) ultrasound in the clinical routine, this study aims to review the application of this diagnostic method in the reproductive tract of females and males of the canine species. A narrative review was carried out by using scientific articles, monographs, dissertations and thesis published and available in online databases: Periodical Capes (Coordination for the Improvement of Higher Education Personnel), SciELO (Scientific Electronic Library Online) and Google Scholar, in addition to specific books on the topic. In female dogs, Doppler ultrasound can be used to evaluate hemodynamic conditions in the estrous cycle (e.g. estimating day of ovulation and fertility, diagnosing early pregnancy, abnormalities, and fetal stress, thus ensuring greater obstetric safety) and identification of diseases, thereby avoiding unnecessary surgical interventions. In male dogs, however, Doppler ultrasound is mainly used in vascular evaluations in order to identify hemodynamic changes due to occurrence of benign prostatic hyperplasia (BPH), most common disease of the prostate and in the assessment of testicular arteries to better understand spermatogenesis and diseases that affect the testicle. In this review, we demonstrate that the use of Doppler mode ultrasound, especially the PW, allows dynamic analysis in clinical examination and complements important information in the diagnosis and treatment of different reproductive disorders in dogs.

“…O processo inflamatório, o qual ocorre no útero é descrito como uma reação exacerbada do endométrio à liberação repetida de progesterona, provocado pelos altos níveis de estrógeno (FERRARI, 2008), o responsável por manter o relaxamento cervical por mais tempo na fase lútea (OLIVEIRA et al, 2008), resultando no acúmulo de fluidos nas glândulas ou na cavidade uterina (LIMA, 2009).…”

O complexo hiperplasia endometrial cística (CHEC) é uma resposta exagerada do endométrio uterino frente à estimulação progesterônica crônica resultando no acúmulo de exsudato no lúmen uterino (QUESSADA et al.,2014). Comumente ocorre durante a fase luteal devido a alta produção de progesterona estimulando assim o crescimento e a atividade secretora das glândulas endometriais e reduzindo a atividade contrátil do miométrio (OLIVEIRA, 2007 apud ALEIXO et al., 2011), porém a administração endógena de progesterona também pode predispor (LIMA, 2019). Ocorre com maior frequência em cadelas do que em gatas, pois a ovulação dos felinos é estimulada pela cópula, ou seja, possuem uma baixa exposição ao aumento de progesterona sérica (BARNI, 2012).
