Long-Term Volumetric Increase of a Free Omental Flap in Breast Reconstruction: A Case Report with a Focus on Body Weight Correlation.

A 53-year-old woman underwent breast reconstruction using a free omental flap following the resection of a phyllodes tumor in the right breast. Postoperative volumetric analysis was retrospectively conducted over 5 years using computed tomography and three-dimensional imaging software. The omental flap demonstrated a 157% increase in volume compared with the immediate postoperative size. A positive correlation (r = 0.93) was observed between body weight and flap volume. Our report is just a single case; therefore, further studies are required to elucidate our hypothesis. To the best of our knowledge, this is the first report to describe this association in an omental flap used for breast reconstruction. These findings may support appropriate surgical planning and postoperative follow-up in reconstructive breast surgery.
