Although the TT can be performed under local anesthesia, this procedure can be extraordinarily painful for the patient. The patient's pain threshold and anxiety level should be taken into consideration. You want the most dramatic transformation possible, and you also do not want to be in pain during the procedure so that the surgeon must stop the procedure or do less than what is necessary. If you move or tighten your abdominal muscles, you may compromise results.Blood clots after TT are not common. Blood clots that lead to pulmonary embolus are even more uncommon. However, if you have more than one risk factor for blood clots other than having a TT surgery, you may need Lovenox or something similar. Your plastic surgeon should be familiar with the Caprini assessment, and he or she should be able to determine if this is indicated.Leave the decision regarding drains to your PS, as he/she will determine what is appropriate for you based upon his/her experience, education, training, and personal preferences.
