Blood Clots

I'm just looking into cyber space to see if by some slim chance anyone on here has had any issues with them? My sister was in the hospital for the 2nd time in 2 years with a deep one. She almost died at 18 years old (which was 20 years ago) from one the broke off and traveld to her heart and lungs.

They tested for every blood test they know of and she came back negative for them all. She's failed cumadine (spelling??) therapy, they don't think it's cancer.

We are at a loss, the doctors here are at a loss so they are basically done tyring to figure it out.

We are trying to get an appointment at the Mayo Clinic for her.

So i guess i'm just reaching!!!
