Abstract

PURPOSE
When reconstruction for patients who have the large contralateral breast or a following large defect after mastectomy is required, conventional pedicled TRAM flap shows the unpredictable occurrence of fat necrosis and skin flap loss in a relatively high percentage due to insufficient blood supply. In an effort to obtain more stable TRAM flap blood circulation, we have performed a supercharged technique using deep inferior epigastric perforators (DIEP) with conventional pedicled TRAM flap. METHODS: From September of 2006 to December of 2008, Fourteen supercharged TRAM flap were performed for breast reconstruction after modified radical mastectomy. The contralateral DIEP was anastomosed to the internal mammary vessels in contralateral pedicled TRAM flap or thoracodorsal vessels in ipsilateral pedicled TRAM flap. Nutrient vessels were selected by Multi-Detector Computed tomography (MD-CT) modalities. For the nutrient vessel, we used deep inferior epigastric vessels (DIEV) of the ipsilateral side in 8 patients, DIEV of the contralateral side in 6 patients. In addition, for the recipient vessel, we used thoracodorsal vessels in 8 patients, internal mammary vessels in 5 patients, intercostals artery perforators in 1 patient.
RESULTS
The mean age was 46.8 years and the average follow-up interval was 14 months. There were 11 immediate and 3 delayed breast reconstructions. Fat necrosis incidence rate in supercharged TRAM group was lower than in conventional TRAM flap group. There were no differences of the incidences of abdominal hernia in both groups.
CONCLUSION
The supercharged TRAM flap produces an improvement in vascularity that permits use of all four zones of the flap. The breast reconstruction with supercharged technique is reliable and valuable methods which provide sufficient soft tissue from abdomen without significant complications.
