title: The distally based superficial sural artery island flap: clinical experiences and modifications.
abstract: The coverage of defects of the Achilles tendon, malleoli, and heel remains a challenge to reconstructive surgeons. The distally based superficial sural artery island flap is vascularized by the median superficial sural artery, posterolateral septal perforators originating from the peroneal artery, neurovascular arteries of the sural nerve, and combinations of these systems as suprafascial plexus. We used distally based superficial sural artery island flaps for the reconstruction of defects of ankle, malleolus, and heel in 17 patients between 1991 and 1997. The largest flap we have used until today was 12 cm in width and 15 cm in length. All flaps have survived. However, we observed venous congestion and edema in two flaps. Also, marginal necrosis occurred in two flaps for which we had not taken the sural nerve with the flap. After these complications, we made some modifications. We left a skin extension over the fasciovascular pedicle and used it as a roof of the tunnel. We took the sural nerve and the deep fascia in all cases. The main advantage of this flap is a constant and reliable blood supply without sacrifice of a major artery. In addition, this is a one-stage, safe and easy procedure that can be used for large defects.
