I Have a Question Regarding the Use of Lovenox After Breast Surgery?

I typically use Lovenox with abdominoplasty surgery or extensive body contouring surgery.  There are several factors that place a patient at an increased risk for DVT or pulmonary embolism.   You did not mention your weight or any other concurrent medical problems.   If you discontinue your Estradiol, have a BMI less than 30, your age is less than 40, and you have no family history or personal history of DVT or PE and no personal history of a malignancy then you really do not meet the criteria for the use of Lovenox.   As physicians we always have to weigh the risks vs. the benefits of everything we do including the use of drugs in the perioperative period.  Your plastic surgeon is in the best position to understand your medical condition and make recommendations in your best interests.  If you disagree then you should communicate your concerns and get answers to your questions.  

I think your instincts are correct and I personally would have the same concerns if I were a patient.  Lovenox can introduce problems of its own, specifically the risk of extra bleeding and hematomas, and even the occasional need for a blood transfusion.  The risk of a blood clot should be very low in a patient like you with no history of blood clots and having the procedures you are having.  I prefer to avoid muscle relaxants in surgery (no paralysis, spontaneous ventilation), avoid prone positioning, and use compressive devices on the legs (almost all surgeons do this today), and get my patients up walking right away.  These habits keep the risk of a blood clot very low and don't introduce possible new problems.  Be sure you are having a vertical lift, which is the most effective type of breast lift.  I've attached some examples from my website.
