Impact of prior ipsilateral chest wall radiation on pedicled TRAM flap breast reconstruction.

Background: This study compares complication rates between transverse rectus abdominis myocutaneous (TRAM) flaps based on previously irradiated versus nonirradiated superior pedicles to assess the impact of prior ipsilateral chest wall radiation on pedicled TRAM flap breast reconstruction. Methods: A retrospective study of 302 consecutive TRAM flap reconstructions was performed; 76 TRAM flaps based on a previously irradiated superior epigastric pedicle were compared to 226 TRAM flaps based on a nonirradiated pedicle in medical comorbidities, oncologic data, and complications. Results: Patients having undergone previous chest wall irradiation had a higher cancer stage, but demographic data were otherwise similar within the groups. Previous chest wall irradiation did not result in increased rate of flap loss, infection, and fat necrosis. However, there was a trend toward higher revision rate in the previously irradiated TRAM group. Conclusions: Previous radiation to the superior epigastric pedicle is not associated with a significant increase in flap complications and should be considered a viable modality for pedicled TRAM flap breast reconstruction.
