Which is better for a tummy tuck, Lovenox or Arixtra?

Each surgeon has their own opinion and protocol regarding use of Lovenox post op in tummy tucks. Personally, I do not because of the risk of bleeding. If you have further questions about the MTFHS gene, and its implications in your particular case, consider a consult with a hematologist.

Arixtra and Lovenox are both effective for chemo-prophylaxis for a blood clot.  Lovenox is a form of low molecular weight heparin and does have a small risk of heparin induced thrombocytopenia (HIT) which is a serious medication reaction that can cause clotting.  With a history of having had a blood clot and having received heparin in the past, you could have been sensitized immunologically to heparin.  I would recommend Arixtra for prophylaxis because it does not have a risk of HIT.  If the blood thinner is used 6-8 hours after surgery, your risk of a blood clot can be reduced without a significantly increased risk of bleeding.  Nonetheless, the risk of bleeding after surgery is not zero and should not be minimized. You should go into surgery with a good understanding to the issues at hand. All the best.

I coldnt agree more iwth Dr. Kunkel. All patients I see with history of DVT are sent to a hematologist for evaluation for baseline hypercoagulability and to discuss prophylaxis. It is possible that a TT  may not be for you.
