About Chronic Venous Insufficiency (CVI)

Chronic venous insufficiency (CVI) is a condition that occurs when the walls and/or valves of the leg veins do not work properly. Veins work to return blood to the heart. For the blood in your legs to return to the heart, it needs to flow upward, so the leg veins’ one-way “valves” stop the blood from flowing back down.

When these valves become damaged, it causes the blood to leak back down and accumulate in the leg veins.

Over time, CVI can cause varicose veins, spider veins and swelling of the legs, itching and the development of ulcers near the ankles.

  • Achy or tired legs
  • Leg ulcers
  • Flaky or itchy skin on the legs or feet

If not treated, CVI and its consequences can become serious. If you have any symptoms of CVI, it is important that you speak to your doctor. The symptoms will not go away untreated.

CVI impacts quality of life.

There are more people who suffer from CVI on a daily basis, versus those who suffer less frequently, like 3-4 times a week, once a week or a couple of times a month.

Many say that their symptoms cause them to have difficulty falling asleep or wake them up during the night because of leg cramps.

Many people find that their symptoms worsen when they’re more active than usual or when they have to spend long periods of time standing.

This can be a serious problem for people who have jobs that require heavy lifting or a lot of standing, like warehouse workers, landscapers, hairdressers, cooks/chefs, pharmacists, security guards, etc.
