[Increasing the reliability of SIEA flap using peroperative fluorescent angiography with indocyanine green in breast...

The lower abdominal skin and fat have become a standard for breast reconstruction. For 30 years, techniques have evolved, seeking to reduce the morbidity while increasing the reliability of the flap. The Superficial Inferior Epigastric flap Artery (SIEA) spares the abdominal fascia and provides a very satisfying autologous breast reconstruction. However, the pedicle of this flap and its angiosome exhibit a considerable variability, making its use less reliable than other abdominal flaps.

The Indocyanine green (ICG) is soluble dye. When illuminated by an near-infrared light, the ICG emits fluorescence that is not trapped by the skin. A single device (Photo Dynamic Eye(®)) provides the emission of the near-infrared light and the reception of the fluorescence. It provides therefore a simple and efficient intraoperative real-time surface angiographic imaging. SURGICAL PROTOCOL: After dissecting the superficial inferior epigastric vessels, the abdominal flap was harvested from the abdominal wall preserving one perforator arising from the deep inferior epigastric vessels. The perforator was then clamped, and the vascular territory of the SEIA artery was visualized using laser-induced fluorescence of the indocyanine green. The surgical technique was modified depending on the indication for surgery and the result of perfusion measurements.

The authors present four clinical cases of breast reconstruction with SIEA to illustrate this procedure.

The SIEA flap is another surgical technique to achieve autologous breast reconstruction without abdominal morbidity or muscular dissection. Intraoperative angiographic imaging with ICG makes this flap more reliable.
