Vein Clinics

Leg vein disease, or chronic venous insufficiency (CVI), occurs when the blood in an unhealthy vein flows backward (referred to as reflux) and the vein is left untreated. This can cause symptoms such as spider veins, varicose veins, discoloration, swelling, heaviness, raised veins, and leg ulcers.

More than 190 million people have CVI or varicose veins globally and more than 30 million Americans suffer from varicose veins, or the more serious form of venous disease called chronic venous insufficiency (CVI), yet the majority remain undiagnosed and untreated. If left untreated, varicose veins can progress to CVI, which can cause pain, swelling and fatigue of the legs, as well as skin damage and ulcers, in more severe cases.
