■ ABSTRACT Introduction: The transverse rectus abdominis myocutaneous flap is a well stablished surgery for breast reconstruction. Its main disadvantage is a large defect in its donor site, leading to weakness in the abdominal wall. Many surgical tactics has been described to address the donor site defect, including direct closure of the muscular aponeurotic and use of polypropylene mesh. The purpose of this study was to assess abdominal hernia and bulge after TRAM flap breast reconstruction using two layers of polypropylene mesh in the donor site defect. Methods: Prospective study in 24 patients who had unilateral TRAM flap breast reconstruction with two layers of polypropylene mesh to close the donor site defect. The patients were evaluated in 3.6 and 12 months of postoperative time for incidence of abdominal hernia and bulge. Results: It was observed one case of abdominal bulge (4.16%) and no case of abdominal hernia. There were no cases of mesh infection or extrusion. Conclusion: The use of two layers of polypropylene mesh in the donor site defect of TRAM flap breast reconstruction resulted in low incidence of abdominal hernia and bulge.
