How to Perform a Transvaginal Ovarian Biopsy
Claire Card, DVM, PhD, DACT; Mariana Diel de Amorim, DVM, DVSc, DACT; and Maria Lopez Rodriguez, DVM
The size of the mare and the deep abdominal position of the ovaries means that diagnostic modalities such as MRI and CT are problematic for use in determining the nature of an ovarian abnormality. However, full-body scans for CT and MRI are available at a few locations in North America. Surgical removal of the suspected abnormal ovary, or both ovaries in case the abnormal ovary cannot be identified, is often performed as it usually provides a definitive diagnosis, and it may be curative. Bilateral ovariectomy, however, does not preserve the mare’s fertility. There are select cases where an ovarian biopsy would be useful to determine which ovary is affected by neoplasia; if both ovaries are neoplastic; or to identify the nature of an ovarian abnormality prior to invasive, and irreversible ovariectomy.
