A Case Report of Uterine Body Constriction Precluding Normal Parturition Leading to Dystocia in a Mare.

Abstract: A 13-year-old multiparous Quarter Horse mare was presented to the Michigan State University's, Large Animal Emergency service for dystocia. Clinical evaluation revealed a minimally dilated cervix on vaginal examination, with a palpable deceased fetus. Postmortem evaluation following owner-elected humane euthanasia revealed a circumferential, tan, fibrous band at the base of the uterine body that constricted the uterus and was adhered to the left and right ovaries. A routine histologic section of the incarcerating cord attached to the ovary consisted predominately of dense fibrous connective tissue, large blood vessels, and a central oviduct suggestive of a rent in the broad ligament. To the authors' knowledge, this is the first case report to describe uterine body constriction that precluded vaginal delivery of a fetus in a late gestation mare.

Summary

The research presents a unique case in veterinary medicine where a 13-year-old Mare experienced problems during childbirth due to a stiff fibrous band found at the base of the uterus. This caused a constraint on the uterus preventing the normal birthing process.

Objective of the Study

  • These researchers embarked on a detailed study of a one-off case involving a multiparous Quarter Horse mare presented with dystocia, a condition where the horse encounters difficulty during childbirth. The existence of a fibrous band constricting the uterus, which posed a significant issue to the birthing process in this late gestation mare, was the focal point of this study.

Conducting the Study

  • An initial clinical evaluation was done to identify the problem. This involved a vaginal examination, which revealed a minimally dilated cervix and a palpable fetus that was no longer alive.
  • The horse was humanely put to sleep as per the owner’s request, and a post mortem evaluation was done to determine the cause of the dystocia.
  • This evaluation uncovered a circumferential, tan, fibrous band at the base of the uterine body that had adhered itself to the left and right ovaries.
  • A histologic section of the band was then analysed. This band, also referred to as incarcerating cord in the context, contained dense fibrous connective tissue, blood vessels of significant size, and a central oviduct which suggested that it could be a rent in the broad ligament.

Significance of the Study

  • Based on the authors’ knowledge, this study provided a first-time account, as part of an official case report, describing the problem of uterine body constriction which hindered the vaginal delivery of a fetus in a mare that was in the late stages of gestation.
  • It offers significant contributions to veterinary obstetrics, specifically in horses, by providing insights into unique issues that could arise during childbirth.
