A microcirurgia em reconstrução mamária. O retalho livre miocutâneo do recto anterior do abdomén.

Abstract

The advantages of the free TRAM flap over the conventional Tram flap are known. The use of its main pedicle--the deep inferior epigastric system--improves the blood supply, decreasing the risk of skin and fat necrosis. The harvesting of 5-7 cm of muscle, and the preservation of its lateral border decreases the risk of abdominal wall bulge or hernias. Delayed breast reconstructions in patients submitted to radiotherapy were performed by end to side anastomosis between flap vessels and axillary vessels, avoiding the thoracodorsal irradiated vessels, and improving the blood flow. Ten patients were submitted to breast reconstruction by free TRAM flaps. There was one total flap necrosis, and one delayed healing around the periumbilical suture. Neither skin nor fat necrosis were seen. One patient developed an abdominal wall bulge. Two patients presenting tumor metastasis abandoned the plastic surgery outpatient clinic. Two patients refused the nipple-areolar complex (NAC) reconstruction. The outcome of five NAC reconstructions was very good, breasts being symmetrical without an opposite breast operation.
