We found an extremely large perforating branch of peroneal artery in an 89-year-old female cadaver's left ankle. The anterior tibial artery could not reach to supply the ankle and dorsum of the foot. The perforating branch of peroneal artery continued as the dorsalis pedis after giving off an anterior lateral malleolar artery branch. The posterior tibial artery was thinner than usual. On the anterior side of the ankle, there was an extra crural fascia in addition to the regular crural fascia, under the anterior crural muscles. This strong fascia was tightly overlying the perforating branch of peroneal artery and anterior tibiofibular ligament. It is important to know the relationship of these vessels to the surrounding structures. Surgeons must be careful while dissecting this area since the perforating branch of peroneal artery might be anomalously enlarged as well as crossing in front of the tibiofibular syndesmosis in order to prevent vascular injury.
我们在一名89岁女性尸体的左脚踝发现了腓动脉的一支极其粗大的穿支。胫前动脉无法延伸至供应脚踝和足背。腓动脉穿支在发出外踝前动脉分支后延续为足背动脉。胫后动脉比平常细。在脚踝前侧，除了正常的小腿筋膜外，在小腿前侧肌肉下方还有一层额外的小腿筋膜。这层坚韧的筋膜紧密覆盖在腓动脉穿支和胫腓前韧带上方。了解这些血管与周围结构的关系很重要。外科医生在解剖该区域时必须小心，因为腓动脉穿支可能异常增粗，并且会在胫腓联合前方交叉，以防止血管损伤。
