Summary
Ovariohysterectomy in mares is a viable treatment for uterine diseases, with a good prognosis despite surgical challenges. This study found a lower prevalence of severe complications than previously reported.
Area of Science:
- Veterinary Surgery
- Equine Medicine
- Reproductive Surgery
Background:
- Ovariohysterectomy in mares is associated with a low mortality rate.
- However, the procedure carries a risk of severe complications requiring review.
Purpose of the Study:
- To evaluate the effectiveness and prognosis of ovariohysterectomy for treating uterine diseases in mares.
- To assess the occurrence of complications associated with this surgical procedure.
Main Methods:
- Retrospective review of medical records for 7 mares undergoing ovariohysterectomy (total or partial) between 1994 and 2001.
- Data collected included diagnosis, surgical technique, postoperative care, complications, and outcomes.
Main Results:
- Indications included chronic pyometra, uterine torsion, and intramural haematoma.
- Postoperative complications were generally mild, including decreased fecal output and mild abdominal pain; severe complications were absent.
- All mares survived and returned to their intended use (riding or embryo transfer).
Conclusions:
- Ovariohysterectomy offers a good prognosis for mares with uterine disease, despite technical surgical difficulties.
- The incidence of life-threatening complications may be lower than previously documented in the literature.
