Abstract:
Seventeen patients were submitted to delayed unilateral breast reconstruction using pedicled, muscle-sparing turbocharged transverse rectus abdominis myocutaneous flap based on the contralateral perforator vessels. The lateral portion of the rectus abdominis muscle on the pedicled side was preserved in 12 patients. Zones II and IV were included in the flap in all cases. Mean duration of surgery was 7 hours and 15 minutes. Four complications developed in the abdominal donor site: contralateral abdominal bulging (n=1), minor suture dehiscence (n=2), and epidermolysis at the border of the abdominal flap and umbilical scar (n=1). Three partial losses (10%-30%) occurred in the reconstructed breast (17.64% of cases), whereas 2 cases of fat necrosis were associated with partial losses. One patient developed deep vein thrombosis with pulmonary embolism; however, outcome was favorable. This proved a viable alternative for breast reconstruction, with satisfactory results in most patients and acceptable morbidity and surgical time.
