Chronic Venous Insufficiency (CVI)

What Is Chronic Venous Insufficiency?

Chronic Venous Insufficiency (CVI) is a common condition that occurs when the veins in the legs have difficulty returning blood back to the heart. This typically happens when the small valves inside the veins become weakened or damaged, allowing blood to flow backward and pool in the lower extremities.

Over time, this increased pressure within the veins can lead to a range of symptoms that affect both comfort and overall circulation.

At California Vein Institute, we provide comprehensive evaluation and treatment for chronic venous insufficiency using advanced imaging and minimally invasive techniques designed to target the underlying cause of the condition.

What Causes CVI?

Healthy veins rely on one-way valves to keep blood moving upward toward the heart. In CVI, these valves do not function properly, a condition often referred to as venous reflux.Several factors may contribute to the development of chronic venous insufficiency, including:

Prolonged standing or sitting
Age-related changes in vein function
Previous blood clots (such as DVT)
Pregnancy
Increased pressure within the veins

As the condition progresses, blood pooling in the legs can place added strain on the vein walls and surrounding tissues.

Symptoms of Chronic Venous Insufficiency

CVI symptoms can vary in severity and often develop gradually. Many patients may not immediately recognize that their symptoms are related to a circulation issue.

Common symptoms include:

Leg swelling, especially after prolonged standing
A feeling of heaviness or aching in the legs
Fatigue in the legs
Visible varicose or spider veins
Skin discoloration near the ankles
Dry, irritated, or thickened skin
Discomfort that improves with leg elevation

In more advanced cases, CVI can lead to skin changes or slow-healing wounds near the lower legs.

How Is CVI Diagnosed?

Diagnosing chronic venous insufficiency typically involves a combination of clinical evaluation and non-invasive imaging.

At California Vein Institute, we use vascular ultrasound to assess blood flow, evaluate vein structure, and identify areas where reflux or blockage may be occurring. This allows our physicians to pinpoint the source of the problem and recommend appropriate treatment options.

Treatment Options for CVI

Treatment for chronic venous insufficiency is focused on improving circulation, reducing symptoms, and addressing the underlying cause of vein dysfunction.

Depending on the severity of the condition, treatment options may include:

Minimally invasive, image-guided procedures to close or treat affected veins
Techniques designed to redirect blood flow to healthier veins
Outpatient treatments that minimize downtime and support faster recovery

At California Vein Institute, we focus on treatments that are precise, targeted, and tailored to each patient’s needs. Many procedures can be performed in a comfortable outpatient setting.

Why Early Treatment Matters

CVI is a progressive condition, meaning symptoms may worsen over time if left untreated. Early evaluation can help identify the condition before it leads to more advanced complications.

Addressing CVI early may help:

Reduce swelling and discomfort
Improve circulation
Prevent progression of vein disease
Support long-term vascular health

If you are experiencing ongoing symptoms, a consultation with a vein specialist can help determine the next steps.
