What causes venous insufficiency in arms?
Venous insufficiency is most often caused by either blood clots or varicose veins. In healthy veins, there is a continuous flow of blood from the limbs back toward the heart. Valves within the veins of the legs help prevent the backflow of blood.
How is venous blood moved through the body?
As blood moves through the capillaries, the oxygen and other nutrients move out into the cells, and waste matter from the cells moves into the capillaries. As the blood leaves the capillaries, it moves through the veins, which become larger and larger to carry the blood back to the heart.

- Sclerotherapy.
- Surgery.
