New Breast Reconstruction Microsurgery Technique Developed by UT Southwestern Doctors
A team of plastic surgeons has developed a new technique for breast reconstitution after mastectomy, which combines the advantages of two commonly used microsurgical procedures that rely on abdominal tissue to rebuild the breast. Flap surgeries are reconstructive surgeries that use tissue from the patient's abdomen, tights, or buttocks — with an intact blood supply — to reconstruct a breast. DIEP (deep inferior epigastric perforator) and SIEA (superficial inferior epigastric artery) are two of the traditional flap techniques used for breast reconstitution. Both harvest skin and fat from the lower abdomen. But whereas DIEP relies on a muscle incision to remove the deep inferior epigastric vessels, an artery and a vein in the abdominal muscle that provide blood supply to the flap, SIEA uses the superficial inferior epigastric vessels present in the flap for blood supply. SIEA is the less invasive technique, but fewer than 20 percent of mastectomy patients are candidates for the procedure and the superficial vessels are very small, often leading to flap loss. The new procedure, performed by University of Texas Southwestern Medical Center surgeons, is called Superior Inferior Epigastric Artery-Deep Inferior Epigastric Artery, or SADIE flap, and improves on the DIEP and SIEA reconstruction techniques. "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," Dr. Sumeet S. Teotia, an associate professor of plastic surgery and a co-developer of the procedure, said in a press release. "In ou
