在解剖一具成年女性标本时,发现右下肢腓动脉终末穿支直接延续为足背动脉。左下肢无明显异常。为积累资料,现报道如下。 右下肢腓动脉终末穿支于外踝最凸点上方5cm处,由小腿骨间膜下方穿出(穿出点外径2.7mm)后,分为升支和降支。降支(外径2.2mm)沿外踝与胫骨之间、趾长伸肌深面下行,于踝关节水平向内下斜行,发出内踝前动脉(外径1.7mm)后,延为足背动脉,沿拇长伸肌肌腱外侧缘下行至第一跖骨间隙。余无异常。升支(外径0.8mm)与胫前动脉(起始点外径1.2mm)终末支吻合,分支布于小腿前群肌。尚有一腓动脉穿支(外径0.7mm)在外踝最凸点上方11cm处穿出小腿骨间膜,沿胫骨
Anatomy of an adult female specimen and found that the right lower extremity peroneal artery terminal perforation directly extended to the dorsalis pedis artery. Left lower extremity no obvious abnormalities. To accumulate information, are reported below. The right lower extremity peroneal artery terminal perforating branch 5cm above the most protruding point of the lateral malleolus, punctured below the interosseous membrane (piercing point diameter 2.7mm), divided into ascending branch and descending branch. Descending branch (diameter 2.2mm) between the lateral malleolus and the tibia, long extensor digitorum deep down in the ankle horizontal oblique downward, issued after the ankle artery (diameter 1.7mm), the extension of the dorsalis pedis artery , Along the lateral extensor hallucis longus lateral to the first metatarsal space. I no exception. Ascending branch (diameter 0.8mm) and the anterior tibial artery (starting point diameter 1.2mm) terminal branch anastomosis, branches in the anterior group of calf muscle. There is a peroneal artery perforator (diameter 0.7mm) in the most lateral bump 11cm above the piercing the interosseous interosseous membrane along the tibia
