Plain-English summary
This report discusses a 5-year-old crossbred Lusitano mare that was found to have a blind vagina during a pre-breeding check-up. Despite being mated twice in the previous breeding season, she did not become pregnant. A thorough examination revealed that her ovaries had follicles and her uterus was enlarged, but an ultrasound showed that the uterus was filled with fluid and there was no connection to the vagina. Further examination indicated that her vagina was unusually short and ended in a blind pouch, leading to a diagnosis of a congenital condition called segmental aplasia of the cranial vagina, which means part of the vagina did not develop properly. The mare's genetic testing showed she had a normal set of chromosomes.
Abstract
This report describes a case of blind vagina diagnosed during a pre-breeding evaluation of a 5-year-old crossbred Lusitano mare. This mare was mated twice during the previous breeding season but remained open. Clinical evaluation revealed the existence of follicles in the ovaries and an enlarged uterus. An ultrasound examination showed that a granular free-floating fluid distended the uterus. No connection was detected between the uterus and the vagina and a presumptive diagnosis of congenital vaginal obstruction was raised. On vaginal examination it was noticed that the vagina was short in depth and ended as a blind pouch. The typical cervical morphology was not observed. Careful evaluation of the clinical situation, both during the follicular and the luteal phases of the mare's oestrous cycle, lead to a diagnosis of segmental aplasia of the cranial vagina. The mare had a normal karyotype on cytogenetic examination [64XX].
