What is the difference between deep vein thrombosis (dvt) and chronic veneous insufficiency (cvt) problems?

Often related: Chronic venous insufficiency often results after suffering dvt. Even if the blood clot is cleared out by the body's natural defenses, the venous valves almost always become stuck to the walls of the veins and no longer prevent blood flow from traveling backward with gravity toward the legs and feet. This is what is called venous insufficiency.

A lot: Dvt is a clot in the deep veins of the legs. Dvt can lead to pieces of the clot breaking off and going to the lungs. This is called a pulmonary embolism and it can cause significant problems even death. Cvi is usually associated with the superficial veins. This is when the valves in the veins do not work and blood can flow backward in the veins. Cvi can cause symptoms such as pain, swelling etc.

Dvt: Dvt indicates a clot whereas chronic venous insufficency usually is caused by reflux though it can also occur as a result of an old dvt
