在３０侧成人下肢标本上，对小腿外侧逆转皮瓣的血供和静脉回流作了解剖学观测。腓动脉终末穿支在外踝上６．１±０．８ｃｍ处穿出小腿骨间膜，分为升支和降支。升支分布到小腿下外侧皮肤区，降支行走在深筋膜深面，经外踝前面进入外踝和距骨隆突之间，至第５跖骨底附近浅出。在踝关节前下发出分支与外踝前动脉、附外侧动脉、跟外侧动脉和足底外侧动脉相吻合，上述动脉均有２条静脉伴行，２条静脉间有丰富吻合。故设计以腓动脉终末穿支降支为血管蒂的小腿外侧逆转皮瓣，皮瓣逆转后，静脉血可通过交通吻合支而回流。用于修复足前部损伤。 Anatomical observations of the blood supply and venous return of the flaps reversed on the lateral leg were performed on 30 adult lower extremity specimens. Peroneal terminal perforating branches in the lateral malleolus 6.1 ± 0.8cm piercing the interosseous interosseous membrane, divided into ascending and descending branch. Ascending branch distribution to the lower lateral skin area, descending branch walking deep fascia, in front of the lateral malleolus and enter the lateral malleolus between the talus, to near the bottom of the fifth metatarsal shallow. Anterior branch of the ankle and anterior branch of the lateral malleolus, attached to the lateral artery, lateral artery and lateral plantar artery coincide, the two arteries with 2 veins accompanied by a rich anastomosis between the two veins. Therefore, the design of the end of peroneal artery to wear branch branches for the pedicle of the pedicle lateral flap reversal, skin flap reversed, venous blood through the traffic anastomosis branch and reflux. Used to repair anterior foot injury.
