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.

摘要

一匹13岁经产的夸特马母马因难产被送至密歇根州立大学大型动物急救服务中心。临床检查发现，阴道检查时子宫颈扩张极小，可触及已死亡的胎儿。经主人选择实施安乐死后的尸检显示，子宫体底部有一条环形、黄褐色的纤维带，该纤维带使子宫收缩，并与左右卵巢粘连。附着于卵巢的闭锁索的常规组织学切片主要由致密的纤维结缔组织、大血管和一条中央输卵管组成，提示阔韧带存在撕裂。据作者所知，这是首例描述子宫体收缩导致妊娠晚期母马无法经阴道分娩胎儿的病例报告。
