Resumo: | Although pyometra is a common disease, the mechanisms that determine cervical opening remain unknown. Knowing that the vascular structures are crucial in pathophysiology, it was observed need for hemodynamic studies assessing uterine artery of female dogs with pyometra and its relation to the neck opening. Thirty-five female dogs were selected and separate into three groups: control group (CG) (n = 12), open-cervix pyometra group (OCG) (n = 11) and closed-cervix pyometra group (CCG) (n = 12), with the objective of evaluating and comparing the hemodynamic changes of the uterine artery [peak systolic velocity (PSV), end diastolic velocity (EDV), and resistance index (RI)] in female dogs with open- and closed-cervix pyometra and correlate them with measurements of uterine diameter (UD) and endometrial thickness (ET). The correlation analysis showed that, with the exception of PSV, the hemodynamics indices were associated with UD and ET, presenting a moderate and positive correlation between UD and EDV (r = 0.62; P<0.01), a moderate and negative correlation between UD and RI (r =-0.68; P<0.01) and also moderate and negative correlation between ET and RI (r = -0.62; P<0.01). These results suggest that alterations of uterine artery hemodynamics are similar in dog females with open- or closed-cervix pyometra, although the UD and the ET can influence in the uterine perfusion. |

Sabiendo que las estructuras vasculares son fundamentales en fisiopatología, fue necesario realizar estudios para evaluar la hemodinámica de la arteria uterina de las perras con piometra y su relación con la apertura cervical. Se seleccionaron 35 perras, distribuidas en tres grupos: grupo control - GC (n = 12); grupo piometra abierto - GPA (n = 11); grupo de piometra cerrado - GPF (n = 12), con el objetivo de evaluar y comparar los cambios hemodinámicos de la arteria uterina (velocidad sistólica pico - PSV; velocidad telediastólica - VED; e índice de resistividad - RI) y correlacionarlos con el valores de diámetro uterino (DU) y espesor endometrial (EE). El análisis de correlación mostró que, a excepción de VPS, los índices hemodinámicos fueron influenciados por DU y EE, con una correlación moderada y positiva entre DU y VED (r = 0,62; P <0,01); moderada y negativa entre DU e IR (r = -0,68; P <0,01) y EE e IR (r = -0,62; P <0,01). Se concluye que las alteraciones hemodinámicas de la arteria uterina son similares en perras con piometra abierta o cerrada, aunque el diámetro uterino y el grosor endometrial provocan reflejos en su perfusión.Apesar da piometra ser uma doença frequente, os mecanismos que determinam a abertura cervical permanecem desconhecidos. Sabendo-se que as estruturas vasculares são fundamentais na fisiopatologia, foi observada necessidade de estudos que avaliassem a hemodinâmica da artéria uterina de cadelas com piometra e sua relação com a abertura cervical. Foram selecionadas 35 cadelas, distribuídas em três grupos: grupo controle – GC (n=12); grupo piometra aberta – GPA (n=11); grupo piometra fechada – GPF (n=12), com objetivo de avaliar e comparar as alterações hemodinâmicas da artéria uterina (velocidade de pico sistólico - VPS; velocidade diastólica final – VED; e índice de resistividade – IR) e correlacioná-los com os valores do diâmetro uterino (DU) e da espessura endometrial (EE). A análise de correlação demonstrou que, excetuando-se VPS, os índices hemodinâmicos sofreram influência do DU e da EE, observando-se, correlação moderada e positiva entre DU e VED (r = 0,62; P<0,01); moderada e negativa entre DU e IR (r =-0,68; P<0,01) e EE e IR (r = -0,62; P<0,01). Conclui-se que as alterações hemodinâmicas da artéria uterina são semelhantes em cadelas com piometra aberta ou fechada, ainda que o diâmetro uterino e a espessura endometrial ocasionem reflexos na sua perfusão.Research, Society and Development2021-08-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1928710.33448/rsd-v10i11.19287Research, Society and Development; Vol. 10 No. 11; e257101119287Research, Society and Development; Vol. 10 Núm. 11; e257101119287Research, Society and Development; v. 10 n. 11; e2571011192872525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/19287/17491Copyright (c) 2021 Camila Franco de Carvalho; Andreia Moreira Martins; Kyrla Cartynalle das Dores Silva Guimarães; Hellen Chaves Barbosa; Daniel Bartoli de Sousa; Mariana Ferreira da Silva; Nathany Arcaten; Andréia Vitor Couto do Amaralhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCarvalho, Camila Franco de Martins, Andreia MoreiraGuimarães, Kyrla Cartynalle das Dores SilvaBarbosa, Hellen ChavesSousa, Daniel Bartoli de Silva, Mariana Ferreira daArcaten, Nathany Amaral, Andréia Vitor Couto do2021-10-23T19:01:11Zoai:ojs.pkp.sfu.ca:article/19287Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:39:12.792255Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
