简要总结
Abdominoplasty is a common cosmetic operation. Some investigators believe that the risk of complications is reduced by limiting the operative dissection. However, this can compromise the quality of the result. This study was undertaken to investigate the blood supply of the abdominoplasty skin flap during surgery using laser fluorescent imaging. An imaging agent is injected and the fluorescence is recorded using a near-infrared laser. The blood supply is tested after a limited dissection and then after a traditional dissection to determine whether an extended dissection reduces the skin circulation. The study hypothesis is that there is no difference in blood supply and the traditional abdominoplasty does not compromise skin circulation.

Protocol
Laser Fluorescent Imaging of Abdominal Skin During Abdominoplasty.
Background/Purpose
Abdominoplasty (tummy tuck) is a common cosmetic operation. One of the risks of surgery is delayed wound healing caused by impaired circulation to the skin. In an effort to reduce risk, some investigators1 advocate a limited-undermining technique, with preservation of the perforating blood vessels and preservation of the Scarpa fascia of the lower abdomen. However, there is no evidence that this limited-undermining technique improves blood supply compared with a traditional abdominoplasty dissection. Such a limited dissection may compromise the cosmetic result.
This study was undertaken to investigate the blood supply of the abdominal skin during the abdominoplasty procedure. By testing the circulation at two points during the dissection, and a third time after completion of the operation, data may be obtained and used to evaluate the effect of the extent of the dissection on blood supply of the skin flap.
