The authors report their experience with immediate breast reconstruction following salvage mastectomy for local recurrence of invasive breast cancer after conservative treatment. From January 1987 to December 1992, among 91 immediate breast reconstructions, 41 were performed for this indication. The results and complications were analyzed for each of the three techniques used: simple prosthesis (n = 5), latissimus dorsi flap with prosthesis (n = 26), trans abdominalis musculocutaneous flap--TRAM flap (n = 10). Immediate flap reconstruction appears to be required in cases of either early or late local relapse since the skin has been irradiated and the mastectomy must be extensive. The transrectus abdominalis flap allows more extensive resection and gives better cosmetic results without the need for a prosthesis.
