Vena Cava Filter ?

I'm having full body lift next week, and a  removable vena cava filter placed this monday. Has any one had experience, or had a friend, family member with a removable filter? How long did the filter remain post surgery? I have Factor V Leiden, one count.They are worried about the clotting factor with such an extensive surgery for 7 hrs. The plastic surgeon likes lovonox post surgery, how many days did you have this? thanks for your help, I appreciate lots of ideas about recovering from major plastics- circumferential lower body lift, 360 degrees slice around hips, body contouring, TT,  butt lift/ agumentation, breast lift/agumentation, You can never be too prepared. ;-)
