Immediate versus delayed free TRAM breast reconstruction: an analysis of perioperative factors and complications

Immediate breast reconstruction provides superior psychological benefit to the patient compared with delayed reconstruction, and has a financial advantage. Smokers undergoing immediate free TRAM breast reconstruction have a higher incidence of flap necrosis than smokers undergoing delayed free TRAM reconstruction. Whereas the differences in psychological benefit, effects of smoking and cost are well addressed in the literature, the differences in morbidity between immediate and delayed free TRAM breast reconstruction are still unknown. Knowledge of any differences would help to determine the best timing for reconstruction, and would support surgical decision making and preoperative patient advice. We present a retrospective review of 105 consecutive free TRAM breast reconstructions performed in 97 patients (89 unilateral and eight bilateral reconstructions). There were 48 immediate reconstructions and 57 delayed reconstructions. In the immediate-reconstruction group six flaps required revision of the anastomosis, and three flaps (6%) were lost. In the delayed-reconstruction group five flaps required revision of the anastomosis, and only one flap (2%) could not be salvaged. Delayed healing of the chest-wall skin flaps only occurred in immediate reconstructions (16%, P = 0.017).
