Jos, please read.
I have a 19yr old Quarter Horse mare that is in foal 224 days today. She started bleeding from her vulva (actually from her cervix) at 156 days and now has been bleeding for almost 10 weeks. The vet checked her the day after she started bleeding and said she would abort the foal within 48hrs. We started her on Uniprim daily and u/s her a week later and the fetus was still alive and seemed to be doing ok. At 183 days we u/s her again and nothing had changed so we went ahead and put her on Regumate.
Right after she began bleeding I called a repro specialist several hours away and he said she had a placentitis and we should keep her on the Uniprim. My vet also spoke with a professor in Louisana and he said there was no way she had a placentitis because she would have already aborted the fetus. He said she probably had twins (missed on post breeding u/s) and one had died and has her placenta/uterus inflamed and it is causing her to bleed.
Like I said this Friday will be 10weeks that she has been bleeding (some days isn't so bad but most days she has dried blood on her hind legs, hindquarters, and a matted tail). She is still on Uniprim and Regumate (until she aborts or carries to term). The fetus is still alive, I feel it move every morning and evening. If you could give me any insight on what could be going on or what the chances of her having a live healthy foal is, I would appreciate it. Thanks, Christi

Has anyone evaluated the CTUP (Combined Thickness of Uterus and Placenta) of the mare using ultrasound? That should indicate the likelihood or absence of placentitis.
Has anyone evaluated the vagina for the presence of a vaginal varicose vein using a speculum? That would be my bet - they're especially common in older mares during pregnancy, and not a threat to the pregnancy.
Bleeding from the vagina in the equine is very rarely a precursor to or indication of impending abortion...

Jos, The vet checked for varicose veins when he palpated her the day after she started bleeding and both times he ultrasounded her. He also wanted to make sure that wasn't the case. Using the speculum you can see that it clearly comes from the cervix.
We have not evaluated the CTUP. When this 1st started without running any tests, he also assumed it to be a placentitis until she kept bleeding every day for weeks on end.
I understand what you are saying about bleeding from the vagina not always being a sign of abortion but what about bleeding from the cervix. It seems to me that something would have to be going on with the mare for her to bleed for 10weeks, especially being on progesterone. Any other ideas since it is from the cervix or have you ever heard of it? Any more info would help, I have done all the research a person can do (books, internet, people, vets, etc). Thanks again Jos!!!!!!
By the way it was also my understanding that a mare with a placentitis or metritis would definately abort within a few days (even on antibotics), have you seen them make a full term delivery on antibotics?

I can't really comment more on the specific situation, as you are lacking diagnostics confirming placentitis without a CTUP and general ultrasonic evaluation.
The standard treatment protocol for placentitis include antibiotics, progestin therapy and anti-prostaglandin therapy. With correct treatment some mares will continue to term - certainly not all, but a good percentage. Likelihood of successful outcome will also depend upon degree of placental separation - something that would be likely to be evaluated by ultrasound - obviously the lower the degree of separation, the more likely the better outcome.
I think if this were my mare I would want more and better diagnostics before sinking lots of money into treatment of an unconfirmed problem.
