Resumo

Background: Wry nose is a congenital deformity that causes respiratory obstruction and decreased oxygenation rate.Gestation in a wry nose mare may be considered a risk to the neonate since it depends on the maternal environment fordevelopment. Compromised oxygenation during pregnancy can lead to fetal distress and cause consequences on fetaldevelopment. However, depending on the degree of the impairment, the fetus may still be able to adapt. The aim of thepresent study was to report the gestation in a mare with facial deviation until term and to assess blood gases in the mareand neonate, and to evaluate the histomorphometry of the placenta.Case: A Criollo breed mare presenting facial deviation (Wry Nose) was donated to Equine Medicine Research Group(ClinEq) of the Federal University of Pelotas (UFPel) due to the presence of the physical deformity. When the mare wasfive years old, it was inseminated and had a pregnancy confirmed. At the fifth month of gestation, evaluation of fetalaorta diameter, fetal orbital diameter and combined thickness of the uterus and placenta (CTUP) started to be performedmonthly to assess gestation health. The assessment of the fetal orbit and aorta diameter revealed a linear increase of bothvariables with the progress of gestation indicating a normal fetal development. CTUP remained in the normal referencerange, presenting no alterations during the gestational length. The mare foaled at 324 days of gestation a coat showing nocongenital deformities. The foaling was monitored until the complete passage of fetal membranes. A complete clinical andhematological evaluation of the foal was carried out after birth. The foal showed normal adaptive behavior, clinical andhematological parameters during the first hours of life, although presenting physical signs of immaturity. Venous bloodsamples were collected from the mare at 315 days of gestation, immediately after foaling and...(AU)
