我们为一39岁男性患者行小腿内侧岛状皮瓣逆行翻转术修复小腿前面溃疡,解剖血管蒂时发现:胫后动脉在腘肌下缘与腓动脉分开后,在趾长屈肌与比目鱼肌之间下行,逐渐变细,在内踝上方浅出深筋膜后逐渐消失,走行过程中发许多分支分布于小腿内侧皮肤。腓动脉先走行于腓骨后内侧,在小腿下1/3段逐渐向内侧走行,经内踝后方到足底。胫神经在小腿中、上段与胫后动脉伴行、前者在后者外侧,在内踝后方与腓静脉伴行,神经在内,动脉在外。在内踝后方,腓动脉发出数支分布于内侧
We performed an anterior cruciate leg ulceration on a 39-year-old man with an island flap pedicled with medial flaps. Anatomy of the pedicle revealed that the posterior tibial artery was separated from the peroneal artery at the inferior margin of the hypothalamus and the peroneal artery, Between the descending, tapering, in the medial malleolus above the superficial fascia gradually disappear, walking in the process of distribution of many branches in the medial skin of the calf. Peroneal artery first walk in the medial fibula, the lower third of the lower leg gradually move to the inside, after the medial malleolus to the plantar. The tibial nerve is in the lower leg. The upper segment is associated with the posterior tibial artery. The former is external to the latter and follows the peroneal and posterior medial malleolus. The nerves are included and the artery is outside. Behind the medial malleolus, the peroneal artery sends several branches distributed on the medial side
