What are the causes of CVI?

What are varicose veins?
Varicose veins are swollen, twisted veins that usually occur in the legs and can be seen just beneath the surface of the skin. They are a common sign of venous insufficiency, where blood is not flowing properly through the veins. Varicose veins occur when the valves in the veins that help blood flow back to the heart become weakened or damaged. This can cause blood to pool in the veins, leading to their enlargement and visible appearance. Varicose veins can cause symptoms such as pain, aching, heaviness, and fatigue in the legs. In severe cases, they can also cause skin changes, ulcerations, and bleeding.
How is CVI diagnosed?
CVI is typically diagnosed through a physical exam, medical history, and tests such as ultrasound and venography. The presence of varicose veins can also help to diagnose CVI.
What are the treatment options for CVI?
Treatment for CVI may include lifestyle changes, compression stockings, medications, and medical procedures such as sclerotherapy, thermal ablation, cyanoacrylate ablation and surgical stripping. It is important to make an appointment with a doctor to discuss treatment options.
