Reconstrucción de defectos amplios en tronco mediante colgajo de perforante en piedra clave

The Keystone Perforator Island Flap (KPIF) is a local fasciocutaneous islanded flap, first published in 2003 by Behan, that does not require identification of the underlying perforator vessels. It permits the closure in a single surgical procedure of both, the defect and the donor site, usually with no need of skin grafting. Our goal is to demonstrate the usefulness of the KPIF for the coverage of large defects of the trunk. Over 120 cases have been reconstructed at our Service using the KPIF from April 2011 to May 2013. We present a series of 5 patients who underwent reconstruction of large defects of the trunk (maximum diameter ranging from 10 to 25 cm) All the surgeries were performed successfully and both, the excision defect and the donor site, were directly closed. All the patients experienced an uneventful intra and postoperative period, and all were satisfied with the eventual aesthetic appearance, without significant deformities or functional impairments. We conclude that KPIF is an optimal flap for the coverage of large defects in the trunk. It allows performing a soft tissue defect reconstruction, while the donor site is closed by direct apposition, with minimal morbidity, good cosmesis, short operative time and at a relatively low economic cost.
