Any surgery has that possibility (death). Maybe the hemorrhagic aspect makes it riskier. My mare’s spay was done eons ago. Long before all the scope procedures. It was a general anesthesia, flip her on her back, two incisions near her udder and wake her up and recover her thing. The vet (both my regular vet and the surgeon) would no longer do the procedure typical for that time due to risk. However, the horse was miserable for 1 week every 3 weeks and was quickly getting to be unrideable during that period and things only would have gotten worse as the tumor grew (it was benign though). What kind of surgical procedure is being discussed? I don’t know what they are doing now. I thought most were done via scope? The vet that did my horse’s created his own procedure due to the complications of the procedure du jour.
Will drug treatment correct the hemorrhage? If so, then is a logical first step. Me, I wanted them gone…yes, did both sides despite the tumor only being on the left side as I wasn’t planning on breeding her and never regretted it. I sold the mare and kept track of her up until she was in her mid teens and she was still going strong.
