altrenogest and Ovarian-Diseases

To assess outcomes and behavior changes associated with bilateral laparoscopic ovariectomies.. Retrospective study.. Fifty-one equids.. Medical records were evaluated from equid bilateral laparoscopic ovariectomies from January 2012 to October 2018 with a potential of 6 months follow-up. Follow-up information obtained by telephone interviews included behavior before and after surgery. Likelihood ratio chi-square tests and odds ratios (OR) with 95% CI were calculated where applicable, with statistical significance at p < .05.. Bilateral ovariectomy was performed in 51 cases, with elective (no pathologic ovaries) ovariectomies performed in 41/51 cases. Occasional estrus-like behavior was observed postoperatively in 14/51 (27%) mares, but the behavior was mild and manageable in all cases. There was no age effect on outcome in all bilateral (p = .56) or elective only (p = .36) cases. In 37/41 (90%) elective cases, improvement was observed in the reason for presentation. Some response to altrenogest administration for behavior modification was observed preoperatively in 12/18 (67%) elective cases. Response to altrenogest was not associated with (p = .31) or able to predict a beneficial response to surgery (OR = 5.5; 95% CI = 0.38-78.57; p = .21).. Response to altrenogest in elective cases may not predict behavioral outcome with ovariectomy. Occasional estrus-like behavior in mares postoperatively was not problematic for any owners. Bilateral ovariectomy is a viable treatment option for owners seeking to alleviate undesirable behavior in mares.. This study should aid veterinarians and horse owners in case selection for bilateral ovariectomy.

An aggressive mare, presented for prebreeding examination, was found to have a significantly enlarged ovary (soccer ball size). A granulosa thecal cell tumor was initially suspected. Following laboratory and repeated clinical examination, the mare was diagnosed with an ovarian hematoma, which regressed with treatment.
