What is Chronic Venous Insufficiency?

Chronic venous insufficiency (CVI) is a long-term condition that affects the veins in the legs, making it difficult for blood to return to the heart. When the vein valves are weakened or damaged, blood pools in the lower legs, leading to swelling, discomfort, and skin changes. If left untreated, CVI can result in serious complications, including venous leg ulcers.

CVI is common in the UK, particularly among adults over the age of 50. Women are more frequently affected, especially after multiple pregnancies. Those with a history of deep vein thrombosis (DVT) or varicose veins are also at a higher risk.

How Chronic Venous Insufficiency Develops

Healthy veins contain one-way valves that help push blood back to the heart. In individuals with CVI, these valves fail, allowing blood to flow backwards (venous reflux). The prolonged pooling of blood increases pressure in the veins, leading to vein enlargement, swelling, and inflammation.

Unlike varicose veins, which are primarily a cosmetic concern, CVI is a progressive condition that can impact overall leg health and mobility.

Main Causes of Chronic Venous Insufficiency

Several factors contribute to the development of CVI, including:

Weak or damaged vein valves – Primary cause of blood pooling
Deep vein thrombosis (DVT) – Blood clots that damage vein walls
Prolonged standing or sitting – Common in office workers, retail, and healthcare professionals
Obesity – Increases pressure on leg veins
Pregnancy – Increased blood volume and hormonal changes weaken veins
Genetic predisposition – Family history of varicose veins or CVI
Smoking – Affects blood circulation and vein health

Understanding these risk factors can help individuals take preventive measures to reduce their chances of developing CVI.

Recognising the Symptoms of CVI

Early detection of CVI can prevent complications. Common symptoms include:

Heavy or aching legs – Worse after prolonged standing
Swollen ankles or lower legs – Especially by the end of the day
Itching or tingling – Can be mistaken for dry skin
Darkening of the skin – Brown or reddish patches near the ankles
Varicose veins – Enlarged, twisted veins on the legs
Skin ulcers – Open wounds that heal slowly or not at all

These symptoms can worsen without treatment, leading to more serious health concerns.

Diagnosing Chronic Venous Insufficiency

A vascular specialist will assess symptoms and use diagnostic tests to confirm CVI. The most common tests include:

Duplex Ultrasound – A non-invasive scan that checks blood flow and vein function
Venogram – Uses contrast dye and X-rays to assess vein health.

Early diagnosis allows for prompt treatment, reducing the risk of complications such as venous leg ulcers.

Treatment Options for Chronic Venous Insufficiency

Treatment for CVI aims to improve circulation, reduce symptoms, and prevent complications. Options range from lifestyle changes to advanced medical procedures.

Lifestyle Changes and Self-Care

Making simple adjustments can help manage CVI symptoms:

Exercise regularly – Walking strengthens calf muscles, improving circulation
Elevate legs – Helps reduce swelling and improve blood flow
Avoid prolonged sitting or standing – Move every 30 minutes to keep blood flowing
Maintain a healthy weight – Reduces strain on the veins
Wear compression stockings – Supports veins and promotes circulation

Medical and Minimally Invasive Treatments

If symptoms persist despite lifestyle changes, minimally invasive treatments can help:

Sclerotherapy – A solution is injected into small veins, causing them to close
Endovenous Laser Ablation (EVLA) – Uses laser energy to seal faulty veins
Radiofrequency Ablation (RFA) – Similar to EVLA but uses radio waves.

These procedures are performed under local anaesthetic and typically require little to no downtime.

Surgical Interventions for Severe Cases

For advanced CVI or when other treatments are ineffective, surgery may be necessary:

Vein Stripping – Removal of damaged veins via small incisions
Valve Repair – Strengthening or replacing faulty vein valves
Vein Bypass – Creating a new vein route for blood flow.

Surgery is usually a last resort and is only recommended for severe or recurring cases of CVI.

Preventing Chronic Venous Insufficiency

While some risk factors, such as genetics, cannot be changed, others can be managed to prevent CVI:

Stay active and incorporate regular movement into daily routines
Maintain a balanced diet rich in fibre and low in salt
Keep hydrated to support healthy circulation
Avoid tight clothing that restricts blood flow
Wear compression stockings if recommended by a specialist

By taking proactive steps, individuals can reduce the likelihood of developing CVI and maintain good vascular health.

Living with Chronic Venous Insufficiency

Managing CVI is possible with the right approach. Sticking to a structured care plan that includes movement, proper leg elevation, and compression therapy can significantly improve symptoms.

Regular check-ups with a vascular specialist ensure the condition is monitored and managed effectively. If new symptoms appear, early intervention can prevent further complications.
