通过解剖尸体标本观察隐动脉及大隐静脉的位置,及其与胫骨及小腿内侧皮肤之间的关系,测量相关血管的外径。可以看到,隐动脉与大隐静脉伴行,在小腿内侧上部与胫前返动脉及来自胫后动脉的肌间隔皮支形成广泛的吻合,除了分布于小腿的内侧皮肤外,还有骨膜支分布于胫骨骨膜,因此可以切取带血供的胫骨皮瓣。该组织瓣包含隐动脉,大隐静脉及较宽的筋膜皮蒂供血系统,血供丰富。当腓骨皮瓣、髂骨皮瓣或肩胛骨皮瓣不能应用时,可以用于修复对侧胫骨及皮肤缺损。
The outer diameter of the relevant blood vessels was measured by dissecting the specimens of the body to observe the position of the saphenous artery and saphenous vein and its relationship with the skin of the medial tibia and calf. It can be seen that the saphenous artery is associated with the saphenous vein and forms an extensive anastomosis between the upper part of the medial side of the lower leg and the anterior tibial artery and the inter-muscular septal branch from the posterior tibial artery. Besides the medial skin of the calf, there are periosteal branches Distributed in the tibial periosteum, so you can cut the tibial flap with blood supply. The flap contains the saphenous artery, saphenous vein and wider fascia Pitti blood system, rich in blood supply. When the fibula flap, ilium flap or scapular flap can not be used, can be used to repair contralateral tibia and skin defects.
