Venous Incompetence

Stagnation of the blood in the veins of the legs due to improper blood flow from veins of the leg back to the heart is known as venous incompetence. In varicose veins, the valves of veins that prevent backflow of the blood are impaired, leading to blood pooling. Weak leg muscles also cause blood stagnation. In case of a blood clot in the leg vein, there is a pooling of blood below the level of the blood clot. Obesity, smoking, pregnancy, sitting or standing for prolonged hours, etc., are certain risk factors. Sclerotherapy, ambulatory phlebectomy, diuretics, anticoagulants, and surgical stripping of the vein offer relief.
