Chronic venous insufficiency (CVI) is a medical condition characterized by blood pooling in the veins, leading to increased pressure and strain on the vein walls. [1] The most common cause of CVI is superficial venous reflux, which often results in the formation of varicose veins, a treatable condition. [2]
Research has also shown the importance of pelvic vein reflux (PVR) in the development of varicose veins. Varicose veins in the legs could be due to ovarian vein reflux. [19] [20] Both ovarian and internal iliac vein reflux causes leg varicose veins. This condition affects 14% of women with varicose veins or 20% of women who have had vaginal ...

Compression stockings are elastic compression garments worn around the leg, compressing the limb. This reduces the diameter of distended veins and increases venous blood flow velocity and valve effectiveness. Compression therapy helps decrease venous pressure, prevents venous stasis and impairments of venous walls, and relieves heavy and aching ...

Some veins are named after the physician who first described them: Dodd's perforator at the inferior 1/3 of the thigh; Boyd's perforator at the knee level
