Plain-English summary
A 13-year-old Quarter Horse mare was brought in for difficulty giving birth (dystocia) and was found to have a constriction in her uterus that prevented the delivery of her fetus. A veterinarian discovered that the cervix was only slightly open and that the fetus had unfortunately passed away. After the owner chose humane euthanasia, a postmortem examination revealed a fibrous band constricting the uterus and attached to the ovaries. This case highlights a rare condition that can complicate delivery in pregnant mares.

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.
