The effect of puerperal uterine disease on uterine involution in cows assessed by Doppler sonography of the uterine arteries

Abstract

The objective of this study was to investigate the effects of puerperal uterine disease on uterine blood flow using trans-rectal Doppler sonography. Lactating Holstein Friesian cows (n = 44) were divided into two groups based on whether they were healthy (UD−; n = 23) or had uterine disease (UD+; n = 21) defined as retained fetal membranes and/or metritis. General clinical examination, vaginoscopy, trans-rectal palpation, and trans-rectal B-Mode sonography were conducted on Days 8, 11, 18, 25 and then every 10 days until Day 65 after calving. Doppler sonography of the uterine arteries was conducted on Day 8, during diestrus after the second ovulation (Days 40-60 after calving) and during diestrus before breeding (Days 63-75 after calving). Cows with uterine disease had greater (P < 0.05) uterine size as assessed trans-rectally compared with cows of the UD group. Sonographic measurements on Day 11 after parturition revealed a greater (P < 0.05) horn diameter in cows of the UD+ than in the UD− group. Both uterine size and uterine horn diameter decreased more earlier following parturition (P < 0.05) in cows of the UD− group. Blood flow volume (BFV) was greater and pulsatility index was less on Day 8 after calving in cows of UD+ than UD− group (P < 0.05). In cows of the UD−, but not in those of the UD+ group, there was a further reduction in BFV subsequent to Day 45 after calving (P < 0.05). The results of this study show that uterine blood flow measures by trans-rectal Doppler sonography are affected by puerperal uterine disease.

Effect of peripartum nutritional supplementation on postpartum fertility and blood biochemical and steroid hormone profile in crossbred cows

“…The rise was significantly (p<0.01) more in nutrients supplemented group than in control from day of calving till day 28 postpartum (Table 2). These findings are in close agreement with earlier reports (Sheldon and Dobson, 2000;Heppelmann et al, 2013). The concentrations of PGFM reflect uterine involution.…”

Bidimensional and Doppler ultrasonographic evaluation of postpartum uterine involution in the queen

“…A decrease in the blood flow of uterine arteries throughout puerperium has been reported in these species. Furthermore, Doppler uterine blood flow measurements are altered by puerperal uterine diseases in women and cows, contributing to the diagnosis of postpartum disorders [2,5,9].…”

“…Além disso, estudos mostram que a claudicação apresenta efeito negativo em relação à fertilidade das vacas leiteiras (SPREACHER; HOSTETLER; KANEENE, 1997;WEBB, 2001;GARBARINO et al, 2004;WALKER et al, 2008;SOOD et al, 2009;MORRIS et al, 2011); relacionando-a, também, a maior incidência de cistos ovarianos (MELENDEZ et al, 2003) PANARACE et al, 2006;HONNENS et al,2008;BATISTA et al, 2013;BLANCO et al, 2014), durante o pós parto fisiológico (KRUEGER et al, 2009;HEPPELMANN et al, 2013a) e pós parto patológico (HEPPELMANN et al, 2013b ;MAGATA et al, 2013).…”

“…Recentemente, estudos têm demonstrado a eficácia da avaliação ultrassonográfica com Doppler em diferentes condições patológicas, tais como a retenção de secundinas (MAGATA et al, 2013), mamite (POTAPOW et al, 2010) e doenças puerperais (HEPPELMANN et al, 2013b).…”
