In this study we conducted the vascular anatomy of sural flap to determine the peroneal artery perforator contribution relative to anatomical landmark of tip of lateral malleolus, include the first peroneal artery perforator to identify safely pivot point of the flap.
A retrospective study of an anatomical study of Vascular supply of the Distally Based Sural Artery Flap was performed by dissection on 12 fresh adult cadavers legs. We recorded number of the perforator, location of each perforators in relationship to the tip of lateral malleolus and location of first peroneal artery perforator.
The anatomical of vascular supply of the distally based sural artery flap, anatomical of peroneal artery perforators was identified and measured from anatomical landmark is tip of lateral malleolus. The mean number of perforators was 3.4 (range, two to five), grouped in 5 perforators at the following average locations proximal to the tip of lateral malleolus: first, at 6.3+0.9 cm; second, at 8.5+1 cm; third, at 11.17+1.4 cm; fourth, at 12.7+1.2 cm; and fifth, at 14.6+0.2 cm proximal to the tip of the lateral malleolus.
Complete vascularization of venoneurofasciocutaneous sural flap was accomplished by peroneal perforator, the blood supply of the distally based sural venoneurofasciocutaneous flap can be pivoted at the lowest perforators in the posterolateral region, which are about 5.4 to 7.2 cm proximal to the tip of lateral malleolus.
在本研究中，我们对腓肠神经营营皮瓣的血管解剖结构进行研究，以确定腓动脉穿支相对于外踝尖解剖标志的贡献，包括识别第一腓动脉穿支以安全确定皮瓣的旋转点。
对12具新鲜成年尸体下肢进行解剖，对远端蒂腓肠神经营营皮瓣的血管供应进行解剖学回顾性研究。我们记录了穿支的数量、每个穿支相对于外踝尖的位置以及第一腓动脉穿支的位置。
确定了远端蒂腓肠神经营营皮瓣的血管供应解剖结构，从外踝尖这一解剖标志处识别并测量了腓动脉穿支的解剖结构。穿支的平均数量为3.4个（范围为2至5个），在外踝尖近端的以下平均位置分为5个穿支：第一个位于外踝尖近端6.3+0.9厘米处；第二个位于8.5+1厘米处；第三个位于11.17+1.4厘米处；第四个位于12.7+1.2厘米处；第五个位于外踝尖近端14.6+0.2厘米处。
腓肠神经营营皮瓣的完全血管化由腓动脉穿支完成，远端蒂腓肠神经营营皮瓣的血供可以在外后侧区域最低的穿支处旋转，这些穿支位于外踝尖近端约5.4至7.2厘米处。
