The posterior tibial vein (PTV) is formed distally by the medial and lateral plantar veins and ends proximally at the joining with the peroneal vein. Variations of the PTV can result in unique clinical presentations. Such variations at the proximal location have been classified previously, but few have been identified distally. In an adult male cadaver, we identified a unilateral distal PTV variation that bifurcated posterior to the medial malleolus. This bifurcation rejoined inferiorly to the medial malleolus and formed a loop that was transected by the posterior tibial artery from deep to superficial. Although this PTV variation is rare, we believe it could be clinically significant for tarsal tunnel syndrome (TTS) and catheter-directed thrombolysis (CDT) of deep vein thrombosis (DVT). Such anatomical variations should be documented and added to clinical databases to improve patient outcomes and diagnostic techniques.
胫后静脉（PTV）由足底内侧静脉和外侧静脉在远端汇合形成，在近端与腓静脉汇合处结束。PTV的变异可导致独特的临床表现。近端位置的此类变异此前已有分类，但远端发现的较少。在一具成年男性尸体中，我们发现了一种单侧远端PTV变异，该变异在内踝后方分叉。此分叉在下方重新与内踝汇合，形成一个环，胫后动脉从深到浅将其横断。尽管这种PTV变异罕见，但我们认为它可能对跗管综合征（TTS）和深静脉血栓形成（DVT）的导管直接溶栓（CDT）具有临床意义。此类解剖变异应记录在案并添加到临床数据库中，以改善患者治疗效果和诊断技术。
