Abstract
Surgical delay is one method of enhancing the vascularity of the lower abdominal transverse rectus abdominis musculocutaneous (TRAM) flap. The outcome of 7 patients who underwent surgical delay (by ligating both superficial and deep inferior epigastric vessels bilaterally) a week prior to definitive TRAM flap elevation is described. Three patients were smokers, 3 were obese, and 1 was an asthmatic on medication. A satisfactory aesthetic result was achieved in all patients and the complications that occurred were minor. Two patients developed minor skin necrosis due to inadequate trimming of zone 4 on the contralateral side to the pedicle and there were 3 cases of fat necrosis, which occurred below Scarpa's fascia. Surgical delay is a useful technique of breast reconstruction. It allows the flap to be centered safely in the lower abdomen. In the high-risk patient, delay may prevent the need for microsurgery or the sacrifice of both recti.
