All of the larger veins in your body, particularly your legs, contain a series of one-way valves. These help your veins perform their primary function of moving blood back towards the heart. If these valves are damaged, gravity causes blood to trickle back down the legs. These valves can be damaged in any number of ways, all of which can lead to CVI.
Doppler ultrasound is ideally suited for diagnosing vein disease. This imaging technique is capable of displaying blood flow in real time, something no other technique can duplicate. Once identified, veins with damaged valves can be treated.
It’s worth noting that both the ultrasound exam used to diagnose CVI and the treatments themselves are often covered by insurance. Some vein problems such as spider veins are purely cosmetic. Others cause physical symptoms which can become quite severe. If these symptoms interfere with your normal, daily activities then treatment will be deemed medically necessary. As a result, it’s highly likely that your insurance plan will cover the costs.
