Anterolateral thigh flap: A review of 168 cases

The anterolateral thigh flap based on the descending branch of the lateral circumflex femoral vessel is one of the musculocutaneous or septocutaneous flaps in the thigh. The descending branch of the lateral circumflex femoral vessel has either perforating branches or direct cutaneous branches from the intermuscular space to the anterolateral femoral skin. Since 1983, we have transferred 168 anterolateral thigh flaps for reconstruction of old burn scars, infected wounds, carcinoma excisions, for coverage of open bone fracture of the lower leg, and for congenital diseases. One hundred fifty-two cases were free flaps. The other 16 cases were pedicled flaps. The skin branches were divided into four types in our clinical series: musculocutaneous perforators (135/168 [80.4%]); intermuscular cutaneous perforators (16/168 [9.5%]); direct cutaneous branches (14/168 [8.3%]); and tiny cutaneous perforators (3/168 [1.8%]). The results were satisfactory. Only one case resulted in a failure due to tiny cutaneous branches.
