Abstract

The gross anatomy of the deep plantar veins has been examined in 14 cadaveric feet in order to assess their function as a 'venous foot pump'. The lateral plantar vein was found to be larger than the medial and is double in its proximal segment. Both plantar veins contain valves which face proximally and have a convoluted and intermuscular course. These features suggest that the deep plantar veins act as a pump that empties during contraction of the intrinsic foot muscles during the stance phase of gait.

摘要

为了评估足底深静脉作为“静脉足泵”的功能，对14具尸体足部的足底深静脉进行了大体解剖研究。发现外侧足底静脉比内侧足底静脉粗大，且其近端段为双支。两条足底静脉均含有瓣膜，瓣膜朝向近端，走行迂曲且位于肌肉之间。这些特征表明，在步态站立期，足底深静脉起到泵的作用，在足部固有肌收缩时排空。
