Chronic Venous Insufficiency

Swelling, skin changes, or ulcers near the ankle may occur when leg veins do not return blood efficiently.

Chronic Venous Insufficiency

What is chronic venous insufficiency?

Chronic venous insufficiency, often called CVI, occurs when valves in the leg veins do not move blood back toward the heart efficiently. Pressure can build in the lower legs and lead to swelling, skin changes, or ulcers.

Common symptoms

  • Ankle or lower leg swelling
  • A heavy, aching, or tight feeling
  • Brown or reddish skin discoloration
  • Itching or irritated skin
  • A wound near the inner ankle

Swelling can also come from a blood clot, heart or kidney problems, medication, infection, or other causes. New one sided swelling needs prompt assessment.

Why it happens

Prior blood clots, pregnancy, family history, excess weight, long periods of standing or sitting, and age can contribute to valve damage or poor vein function.

How we evaluate leg and ankle swelling

We review the pattern of swelling, examine the skin and wounds, and compare both legs. Noninvasive venous testing may be used to assess blood flow and valve function. Coordination with vascular or medical specialists may be needed.

Treatment options

Care may include:

  • Elevation and movement guidance
  • Compression when circulation and health status allow it
  • Skin care
  • Wound care and pressure management
  • Coordination for vein treatment when appropriate

Compression should be chosen carefully when arterial circulation is reduced or certain health conditions are present.

When to schedule an appointment

Seek urgent evaluation for sudden one sided swelling, warmth, redness, chest pain, or shortness of breath. Schedule care for ongoing swelling, skin discoloration, or an open wound.

Frequently asked questions

Is venous insufficiency the same as PAD?

No. Venous insufficiency affects blood returning through veins. PAD affects blood moving to the legs through arteries.

Why is the skin turning brown near my ankle?

Longstanding venous pressure can allow blood components to collect in tissue and change skin color.

Can compression socks help?

They may help many people, but the correct strength and fit should be based on circulation and medical history.

How to prepare for your appointment

Bring a medication list, relevant glucose information, prior circulation or nerve test results, and the shoes you wear most often. Tell us about previous wounds, infections, or changes in sensation.
