Vein Regional Lateral

**Marginal lateral vein (lat. vena marginalis laterālis)** – anatomical structure of the spinal column and chest. It connects the external subclan vein with the outer chest wall and subcutaneous tissue, providing direct blood flow to the thigh. The right and left marginal lateral veins arise from the posterior surface of the lower part of the body of the talus. They run along the sides, superior, and medial to the surface of the scaphoid before joining together inferiorly and posteriorly to the talus. They then pass lateral to the condyle, located in the spaces between the calcaneal groove and plantar tubercle on the medial side and the midfascia on the lateral side, respectively.

They are involved in venous drainage in the area of ​​the knee joint and one of the key structures of the venous circulation of the foot. Venous outflow from the patella, distal surface of the leg, anterior and lateral surface of the foot occurs mainly through the marginal ulnar veins. Like the posterior satellite of the saphenous veins, the marginal neural veins also drain into the great saphenous vein or the right brachial vein. The described possibility of flowing into a large cavitary lymph node makes the marginal venous networks important links in the venous and lymphatic system. The venous circulation in the distal foot probably consists of several layers of venous networks. When the peripheral venous arteriovenous shunt continues to force the superficial structures of the skin to be fed with relatively oxygen-rich venous blood, it can accelerate pathological skin repair and lead to hyperophic fibrous dysplasia.
