Tummy tuck is one of those procedures in cosmetic surgery which produces the highest risk for DVT, deep venous thrombosis, which occurs when blood clots form in the veins of the extremity or pelvic area. Abdominal procedures, and those over three hours seem to have a higher risk profile, though DVT can be seen with breast reduction surgery as well. The presence of DVT often goes unrecognized, but can lead to PE, pulmonary embolism, where the blood clots impede the blood flow to the lungs, sometimes with fatal consequences.
You have had two prior episodes of PE, and are on medication to prevent a recurrence, and have a protective filter in your system as well. The key to DVT and PE is to understand that the complication is preventable. Understanding your risk for the occurrence and proper medical management can prevent the repeat of PE. Let me say, that with proper management, you may consider a tummy tuck. It can be performed with safety. Your care, however, should be in a hospital with support and what we call prophylaxis, preventive medication, and resumption of coumadin as the prophylaxis is tapered. Your tummy tuck is likely to cost more that most, but the office based experience is not for you. You need not give up your hope for tummy tuck, just choose your surgeon with care.
Best of luck.
