The microvascular augmented subdermal vascular network (ma-SVN) flap: its variations and recent development in using intercostal perforators

Abstract

In 1994 we reported the use of the microvascular augmented occipito-cervico-dorsal 'super-thin' flap for reconstruction of the cervical region in three cases. Since this preliminary report, we have performed a further 17 flaps, and the usefulness of the flap in the treatment of anterior cervical scar contractures in extensively burned patients has become apparent. Moreover, we have devised flaps with not only a narrow skin pedicle but also myocutaneous or island vascular pedicles. Various augmentation vessels, including myocutaneous perforators of the intercostal spaces in the back and chest, have also been used successfully. Here, we describe the microvascular augmented subdermal vascular network flaps that we have devised.
