Blood pools in the vessels when the veins cannot pump blood back to the heart.
Varicose veins are painful, gnarled, enlarged veins that most commonly appear on the legs and feet. They occur when the valves inside the vein are too weak or damaged to push blood back to the heart. As a result, blood flows backward (reflux), pools inside the vein, and causes it to swell.
Varicose Veins Procedures
There are some minimally invasive procedures that can help restore blood flow to the heart by closing the diseased vein and rerouting the blood to the healthier veins. One procedure involves the injection of non-formulated medical adhesive or foam to close the diseased vein. Other options are radiofrequency ablation (RF Ablation) or Endovenous Laser Ablation (EVLT). RF Ablation and EVLT procedures involve the use of heat to close off the vein.
It is possible that to manage venous insufficiency by using non-surgical treatments. Elevating the legs while sitting or during sleep can help reduce the swelling of the legs and provide relief for other symptoms. Compression stockings are elastic hosiery that can improve blood circulation by applying pressure to the legs and compressing the diseased veins. Patients with varicose veins should avoid standing or sitting for a prolonged period of time. Exercise and weight loss are also beneficial for treating venous insufficiency
