Is It Possible to Have Tummy Tuck for a Patient with DVT?

You may be able to proceed with tummy tuck, although with an increased overall risk. The medical doctor managing your anticoagulation should be consulted and the circumstances reviewed. It may be considered OK to proceed while you are on a form of anticoagulation. This does increase your risk of bleeding from surgery.

Deep venous thrombosis is at risk with any surgical procedure. Having a history of her previous DVT certainly does increase your risk for this to happen again. It does not, however, preclude your ability to have surgery. One must always weigh the relative risks versus the benefits of procedure and proceed only if the benefits outweigh the risks.
Veins that are clotted due to a deep venous thrombosis will normally open up again after a period of time. I suspect you were treated with anticoagulation such as Coumadin for a period of time after your diagnosis. This helps to prevent progression of the clot and allows for its gradual resorption. Just because you had this problem once before does not mean it will happen again.
Precautions can be taken during her surgery. These precautions can reduce your risk to an acceptable level. Measures that can reduce your risk for deep venous thrombosis include use of compressive pumps on your legs during the surgery and a low dose anticoagulant that is given after your surgery. This medication, called Lovenox, is injected underneath the skin daily for five to seven days after your surgery. This will significantly reduce your risk for another DVT. I would suggest you discuss your concerns with your surgeon.
