I was diagnosed with pelvic varicose veins. I have a tummy tuck scheduled in 3 weeks. Should I be concerned about complications?

your surgeon should be heightened alert for problems and consider using prophylaxis to help prevent DVT's at some risk of more bleeding from your procedure.  You should discuss your concerns with your surgeon and the two of you agree on some plan that is acceptable to both of you.

Thank you for this important question. One of our major concerns in any elective surgery involves the formation of blood clots called a Deep Venous Thrombosis (DVT). When these occur in the lower legs, they rarely cause any long-term problem. However, those that form in the pelvic area can dislodge and travel to the lungs causing a Pulmonary Embolism (PE). This condition can be rapidly fatal. We take surgical precautions to prevent this complication including the use of Sequential Compression Devices (SCD) to gently compress the lower legs during the procedure. Adequate hydration, early ambulation, and avoidance of hormonal therapies are also very important. In addition, many practitioners will have their patients on an anti-coagulant medication post-operatively.This is definitely something to discuss at length before your procedure. Please make your plastic surgeon aware of your condition immediately. Best of luck to you.

This is something that you need to discuss with your surgeon.  The pelvic varicose veins do increase your risk for blood clots.  Your surgeon may choose to take specific actions in light of this information for your safety during and after the surgery.
