This review aims to summarize present knowledge of foot venous return, with a special interest in clinical and research implications.
It is based on the latest available publications on foot anatomy and hemodynamics.
Five systems are described: the superficial veins of the sole, the deep veins of the sole (with particular attention to the lateral plantar vein), the superficial dorsal plexus, the marginal veins and the dorsal arch and the perforating system. The Foot Pump: The physiology of venous return is briefly described, with an emphasis on the differences between standing and walking and the interplay of the foot and calf venous systems.
The hypothesis that the foot and calf venous systems may be in conflict in several clinical conditions (localization of leg ulcers, corona phlebectatica, foot vein dilatation, arteriovenous fistulas of the foot, foot-free bandaging) is presented, briefly discussed, and mechanistically interpreted.
Foot venous return could be more important than is commonly thought. Certain clinical conditions could be explained by a conflict between the mechanisms of the foot pump and the leg pumps most proximal to the foot, rather than by generic pump insufficiency, with possible effects on treatment and compression strategies.
本文旨在总结目前关于足部静脉回流的知识，特别关注其临床和研究意义。
本研究基于足部解剖学和血液动力学方面的最新可用文献。
描述了五个系统：足底浅表静脉、足底深部静脉（特别关注外侧足底静脉）、足底背侧浅丛、边缘静脉和背弓及穿通系统。足部泵：简要描述了静脉回流的生理学，重点介绍了站立和行走之间的差异以及足部和小腿静脉系统的相互作用。
提出了在几种临床情况下（腿部溃疡、冠状静脉曲张、足部静脉扩张、足部动静脉瘘、足部无绷带包扎），足部和小腿静脉系统可能存在冲突的假说，简要讨论并从机制上进行了解释。
足部静脉回流可能比人们通常认为的更为重要。某些临床情况可能是由足部泵与足部最接近的腿部泵的机制之间的冲突引起的，而不是由通用的泵功能不全引起的，这可能对治疗和压缩策略产生影响。
