Free transverse rectus abdominis myocutaneous flap for breast reconstruction in patients with prior abdominal contouring procedures

With an increasing number of women undergoing abdominal liposuction and abdominoplasties, patients who have a history of an abdominal-contouring procedure are now presenting to plastic surgeons with breast cancer and are interested in autologous breast reconstruction. Based on the principle of vascular ingrowth and experience of seeing intact perforators arise from the rectus abdominis muscle in repeat abdominoplasty patients, it was hypothesized that these new perforators could adequately and safely supply the abdominal skin island as a flap in this patient population. A retrospective chart review was performed searching for cases of free transverse rectus abdominis myocutaneous (TRAM) or deep inferior epigastric perforator (DIEP) flap breast reconstruction in patients with a prior history of either abdominal liposuction, abdominoplasty, or both. Three successful cases of free TRAM flap breast reconstruction were performed in patients who had undergone previous full abdominoplasties. Additionally, three successful cases of free TRAM or DIEP flaps were performed in patients after abdominal liposuction. Major complications included one anterial thrombosis in which the flap was salvaged. This study demonstrates the feasibility and viability of free TRAM flaps after previous abdominoplasty and DIEP flaps following prior abdominal liposuction. This is an important advance in the potential uses of the free TRAM flap.
