Clinical experience and surgical anatomy of 32 free anterolateral thigh flap transplantations.

The anterolateral thigh flap, first described by Song, is one of the septocutaneous flaps in the thigh. Since November 1985 we have transferred 32 anterolateral thigh flaps successfully without any loss. Six of these flaps were performed in Australia. The vascular pedicles are divided into three types: fasciocutaneous perforator (37.5%-12/32), vertical musculocutaneous perforator (56.2%-18/32) and horizontal musculocutaneous perforator (6.6%-2/32). This paper presents the surgical anatomy of the flap and clinical experience.
