Plastic surgeons develop innovative microsurgery technique for reconstructing breast after mastectomy

DALLAS – UT Southwestern Medical Center plastic surgeons have developed a new breast reconstruction technique that combines advantages of two different types of microsurgical procedures using abdominal and other tissue to reconstruct the breast after a mastectomy.

Flap-based procedures use a woman’s own tissue taken from the abdomen, thigh, or buttocks to reconstruct the breast. Surgeons have labeled the new procedure Superficial Inferior Epigastric Artery-Deep Inferior Epigastric Artery or SADIE Flap, an enhancement of existing techniques when more traditional flap surgeries called DIEP or SIEA aren’t ideal.

“In traditional SIEA flaps, there can be considerable ‘mismatch’ of blood vessels when bypassed into the chest. This is what can make the traditional SIEA flap inconsistent and unreliable in terms of success,” said Dr. Sumeet S. Teotia, Associate Professor of Plastic Surgery, who developed the procedure with Dr. Nicholas Haddock, Assistant Professor of Plastic Surgery. “In our approach, even though the technique and surgery demands high level of experience with usual DIEP/SIEA flaps, there is no ‘mismatch’ of blood vessels, and the flow of blood is not burdened by any turbulence issues.”

Similar to attempting to attach two mismatched pipes together, one smaller and one larger, it is difficult to get a perfect ‘seal’ of the pipe and the two mismatched pipes can cause turbulence and anatomical mismatch, the surgeons explained. Debris can then build up, causing clogging – or in the case of arteries – clotting. To solve this dilemma, the smaller pipe has to have an intermediary pipe which at one end is smaller and other end larger.

“We have essentially created an ‘intermediate’ pipe system to artery mismatch of the SIEA flap to join the chest side,” Dr. Haddock said. “We bypassed the SIEA into DIEA system, and then that got bypassed into the chest, with no size mismatches and all end to end connections. In this case, there is no ‘debris’ build up into arterial system. The high flow system of the chest keeps everything streamlined into the smaller system as it flows in and out.”

The SADIE flap surgeries are complex and require a team of experienced microsurgeons, who already have high success with traditional DIEP/SIEA flaps, they noted. “This type of work is at the level of Super-MicroSurgery where instruments used are specifically designed for such procedures. We already have experience with this in our other multiple-flap based techniques,” Dr. Teotia said. The UTSW surgeons have completed three such surgeries, and hope that with more experience they can expand the use of the traditional SIEA flap as well.

UT Southwestern Medical Center was among the first in the world to offer a four-flap breast reconstruction, using fat and skin from the back of each leg and from two spots on the stomach to reconstruct natural breast materials. UTSW breast microsurgical team already has one of the largest experiences in the world with multiple-flap based surgeries combined from different parts of the body.

The microsurgery techniques are part of UT Southwestern’s Breast Reconstruction Program, in association with UT Southwestern’s Harold C. Simmons Comprehensive Cancer Center. UT Southwestern’s breast reconstruction specialists work with breast cancer specialists to help women make the best decision for reconstruction after breast cancer, based on health, anticipated cancer treatments, projected recovery time, body shape, and other factors.

Dr. Haddock is a pioneer in the surgery from back of the thigh, and his expertise, combined by Dr. Teotia’s pioneering work in multiple flaps from the abdomen, continues to improve the aesthetic outcomes for patients seeking a high level of breast reconstructive care. The breast reconstruction program continues to gain recognition nationally.

UT Southwestern’s Department of Plastic Surgery is nationally and internationally recognized for delivering outstanding, innovative clinical care to both adult and pediatric patients, including the development of groundbreaking cosmetic and reconstructive procedures that improve patients’ lives, and includes the largest Plastic Surgery training program in the country. Patients consistently rank UT Southwestern’s Department of Plastic Surgery high in satisfaction. According to surveys compiled and analyzed by Press Ganey, UT Southwestern Plastic Surgery’s satisfaction scores are among the top in the nation, scoring higher than 99 percent of other practices in our peer group.
