“…Onen et al [10] have stated that high PI values of fetal aorta are strongly correlated with poor pregnancy outcome, fetal distress and a high c-section rate. In the presented cases, PI values of fetal aorta were found higher in Case 1, 2 and 4 compared to the findings of Scotti et al [3] . The increased PI value of these cases may indicate fetal distress and intrauterine fetal growth restriction.…”

“…However D-USG alone is not sufficient for the evaluation of fetal well-being, but this technique enables the doctor to diagnose fetal distress earlier than other tests [1] . Obstetric D-USG gives the doctor a reliable opportunity to review maternal and fetal hemodynamics by investigating the vessels like the umbilical artery and vein, uteroplacental arteries, fetal thoracic aorta, fetal caudal vena cava and fetal cerebral artery [2,3] . Abnormal vascular placental development in fetal and/or maternal compartments may be an indicator of intrauterine growth restriction, fetal distress and early pregnancy failure [4,5] .…”

“…They are high PI and RI values; absent end diastolic flow and reversed end diastolic flow [2] . In recent studies of veterinary practice [3,6,7] it has been reported that the PI and RI of the umbilical artery progressively decrease and reach the lowest level at delivery. The PI and RI values of the umbilical artery at the prenatal period were found in the range of 1.05-1.39 and 0.70-0.75 respectively in these studies.…”

Doppler ultrasonography has been becoming an essential tool in veterinary medicine, especially in theriogenology. It has being widely used for the evaluation of fetal well-being in pathologic pregnancies in human medicine. The paper highlights the usage of Doppler ultrasonography in veterinary obstetrical pathologies with a review of literature of human and veterinary medicine. Four cats with dystocia and their fetuses were evaluated for fetal and maternal hemodynamics. As a conclusion, flow velocity of the fetal and feto-maternal vessels can inform us of the existence of the pathology related to gestation and also can help choosing the method of treatment in veterinary medicine. Keywords: Cat, Dystocia, Doppler ultrasonography, Feto-maternal vessel Kedilerde Güç Doğum Sırasında Fötal ve Föto-Maternal Damarların Doppler Değerlendirilmesi: Dört Olgu ÖzetDoppler ultrasonografi, başta teriyojenoloji olmak üzere veteriner hekimlikte sıklıkla başvurulan yöntemlerden biri olmaya başlamıştır. İnsanlarda özellikle patolojik gebeliklerde fötal iyilik halinin değerlendirilmesi amacıyla yaygın olarak kullanılmaktadır. Bu makalede, tıp ve veteriner hekimliğinde yer alan literatürlerin derlenmesiyle beraber, veteriner obstetrik patolojilerde Doppler ultrasonografi kullanımının aydınlatılması amaçlanmıştır. Güç doğum şikayeti bulunan dört adet kedi ve bu kedilere ait fötuslarda fötal ve maternal hemodinamik değerlendirilmiştir. Sonuç olarak, fötal ve föto-maternal damarlara ait akım hızlarının gebelik patolojilerinin belirlenmesinde kullanılabileceği ve güç doğum olgularında tercih edilecek tedavi metodunun belirlenmesinde yardımcı olabileceği düşünülmüştür.

“…Several studies addressed the role of the vascularity of genital organs in the estrous cycle, reproductive life, and gestation (Reed et al 1996, Nautrup 1998, Bollwein et al 2000, 2002a, 2002b, Köster et al 2001, Alvarez-Clau & Liste 2005, Di Salvo et al 2006, Scotti et al 2008, Brito et al 2010, Polisca et al 2010, Blanco et al 2011, Pereira et al 2012a, 2012b. Color-Doppler ultrasonography was previously used in cows to evaluate the vascularity of follicle, CL, and conceptus (Myamoto et al 2005, Pareja et al 2010, Silva et al 2010).…”

Follicle and corpus luteum size and vascularity as predictors of fertility at the time of artificial insemination and embryo transfer in beef cattle

Abstract:Two ultrasound based fertility prediction methods were tested prior to embryo transfer (ET) and artificial insemination (AI) in cattle. Female bovines were submitted to estrous synchronization prior to ET and AI. Animals were scanned immediately before ET and AI procedure to target follicle and corpus luteum (CL) size and vascularity. In addition, inseminated animals were also scanned eleven days after insemination to target CL size and vascularity. All data was compared with fertility by using gestational diagnosis 35 days after ovulation. Prior to ET, CL vascularity showed a positive correlation with fertility, and no pregnancy occurred in animals with less than 40% of CL vascularity. Prior to AI and also eleven days after AI, no relationship with fertility was seen in all parameters analyzed (follicle and CL size and vascularity), and contrary, cows with CL vascularity greater than 70% exhibit lower fertility. In inseminated animals, follicle size and vascularity was positive related with CL size and vascularity, as shown by the presence of greater CL size and vascularity originated from follicle with also greater size and vascularity. This is the first time that ultrasound based fertility prediction methods were tested prior to ET and AI and showed an application in ET, but not in AI programs. Further studies are needed including hormone profile evaluation to improve conclusion.

Ultrasonography is a non-invasive, fast and accurate method for early pregnancy diagnosis (Yotov, 2020), monitoring of the embryofetal development (Bartlewski et al., 2000), estimation of fetal number and sex (Karen et al., 2009;Santos et al., 2007), determination of changes in reproductive organs (Atanasov et al., 2012) and mammary gland (Fasulkov et al., 2018) in ruminants.In goats, B-mode ultrasonography is mainly used for diagnosis of early pregnancy, monitoring of embryo-fetal development,
