does anyone have some info on saddle thrombus? My horse was diagnosed ( an educated guess ) by the vet today. I am a member... but don't see any articles on this topic? I am looking for typical symptoms and treatments. My horse presented chronically not acute. I can share more info found on exam if anyone can help. The vet is working on a drug cocktail, heparin, edta etc. to be given IV over a 5hr period.

Hello Marci,
A good topic for which we do not have an article. I will put it on the list for this week and let you know when it is posted.

Thanks Dr. O,

I read the article, and as usual it is very informative. I am not sure that my horse's diagnosis really fits that picture, which is what I expected when looking for further information. Maybe you ( or anyone else with insight) could help point my vet and I in a different direction...
1) not lame at rest, sound at walk, & in pasture
2) no heat
3) shortened stride behind after 10 min. hard working trot.
4) no evidence of any pain/lameness on flexions
5) L patella seems more mobile when palpated
6) after work/ trailering holds LH up and away from body ( like a male dog urinating *G*)
7) vet felt that L saphenous filled slower than Rt

So, really working and in the pasture, I would harldy have noticed the slight shortened stride, but then holding his leg up, and almost 3 legged lame after work is rather scarry. It resolves within a few hours, and he is back to normal. This has been chronic, we just purchaced him. The last owners had given him 6 months rest, but the "sore stifle" ( undiagnosed, just their guess) wasn't resolved.

Well, the number one complaint with thrombus is decreased performance. I could see where a partial occulsion might behave this way but so will some type lamenesses: particularly muscle spasms. I agree with your implied thought: you need some more work up to make a diagnosis.
