Aimee's Mom...hang in there! I am so sorry this has been such a struggle for you all. We will keep hoping for you and sending positive thoughts your way. I do have one suggestion, that even to me sounds a little bit crazy, because I have just recently learned about it, but maybe ask your vet about something called Wobenzym N? It is basically a combination of natural digestive enzymes, but they are enteric-coated so that when you give them on an empty stomach, they don't break down until they are in the small intestine. From there, the theory is by getting into the bloodstream, they reduce all kinds of inflammation. I suggest looking into it for a number of reasons...obviously, the inflammation reduction, but also, I remember reading that it has some blood-thinning properties that you have to be careful of...but in your case, it seems that might actually be a good thing, if it helped to break up that clot? I am not one to jump all over a 'miracle cure' claiming product, but since you have been forced by the limits of traditional medicine into seeking alternative options, maybe this one is worth investigating? I guess I am just thinking...if it came down to your needing a 'hail Mary pass'...it would certainly be worth a try. It's OTC, by the way, but spendy.
Good luck, and please keep us posted on your sweet girl!
