Abstract
Patients with abundant abdominal skin were selected for Avelar abdominoplasty as a safe ambulatory procedure by preserving the vascularisation of the abdominal flap.
284 consecutive patients were operated using IV sedation and tumescent solution. Following liposuction and superficial skin resection, undermining was restricted to the median plane for umbilicus transposition. Skin perfusion was measured using a laser Doppler flow assessment system.
There were no intraoperative complications and no major postoperative complications. Postoperative wound infections were observed in 13 patients (4,5%).There were no cases of skin necrosis, postoperative bleeding or seroma despite not using drains in any cases. The measurement of skin perfusion has demonstrated only a minimal postoperative reduction of perfusion in the lower abdominal flap.
The modified Avelar technique has proven to be a safe ambulatory procedure. The perfusion of the abdominal flap is maintained thus avoiding necrosis and reducing wound complications. In comparison to studies of flap perfusion after more traditional procedures, the preservation of perfusion and also of the lymphatic system appears to be very beneficial.
