Longaderen

Longaderen is a term sometimes used to refer to the saphenous veins, particularly the great saphenous vein, which is the longest vein in the body. These superficial veins run along the inner side of the leg and thigh. The great saphenous vein originates from the dorsal venous arch of the foot and ascends up the leg, passing in front of the medial malleolus, then running up the medial side of the tibia and femur. It typically drains into the femoral vein in the groin area via the saphenofemoral junction.

The longaderen, or saphenous veins, play a role in returning deoxygenated blood from the skin and superficial tissues of the legs back to the deeper venous system and ultimately to the heart. Due to their superficial location and the effect of gravity, these veins are susceptible to developing conditions such as varicose veins. Varicose veins occur when the valves within the veins become weakened or damaged, leading to blood pooling and the veins becoming enlarged and twisted. Procedures like vein stripping or ablation, which target the longaderen, have historically been used to treat symptomatic varicose veins.
