ABSTRACT

The prefabrication of a flap adds one or more tissues to a vascular carrier before being transfered. The prefabrication is based on the delay phenomenon and microvascular modifications. One of the most used flaps in plastic surgery is the TRAM flap, although in some cases it can´t be used because of substantial vascular modifications. Material and methods: A myocutaneous flap was prefabricated with the latissumus dorsi muscle and abdominal skin in Wistar rats. Two groups were formed. In the experimental group a delay procedure was preformed in a skin flap of 2 x 5 cm, adding the latissimus dorsi muscle as a vascular carrier and sutured to the abdominal middle line. In the control group no delay procedure was preformed. Results: In the prefabrication of this flap we observed minimal necrosis in the delay group (p ‹ 0.001) while in the non delay group extensive necrosis was observed. Conclusion: We successfully created a latissimus dorsi reverse flap with abdominal skin dimension similar to TRAM flap but with a different vascular carrier.
