Deep inferior epigastric perforator flap is the newest offering. Skin and fat -- but little or no muscle -- are removed from the lower abdomen and reconnected to the breast in microsurgery.
About six weeks
A less than 2 percent danger of infection or bleeding remains. The flap may require surgery to restore blood circulation.
There's a scar at the donor site, but with no muscle moved, you don't have muscle weakness. You also don't need physical therapy to strengthen other muscles to compensate.
