what is vascular insufficiency
Venous insufficiency is a chronic condition in which blood does not flow normally up through the veins in the legs toward the heart. In normal veins a series of specialized, one-way valves work together, opening to allow blood to flow upward, then closing to keep the blood from flowing back toward the feet.enous insufficiency means that some of your veins aren't working properly. This condition often develops after veins are damaged by an injury, surgery, or blood clot. Veins drain blood and fluid back to the heart, so people with venous insufficiency usually have symptoms caused by the buildup of fluid.
