Warning Signs You May Have Chronic Venous Insufficiency

Chronic venous insufficiency (CVI) is a condition where the veins in your legs struggle to send blood back to the heart efficiently. It's far more common than most people realize — affecting approximately 40% of adults in the United States — and it's one of the leading causes of varicose veins, leg ulcers, and chronic leg pain. The challenge is that many people dismiss their symptoms as just "tired legs" without realizing there's an underlying vascular problem.

What Causes Chronic Venous Insufficiency?

CVI occurs when the one-way valves inside your leg veins become damaged or weakened. These valves normally prevent blood from flowing backward as it travels from your legs to your heart. When they fail, blood pools in the lower legs — a condition called venous reflux. Over time, this increased pressure damages the vein walls and surrounding tissue.

Risk factors include: a history of deep vein thrombosis (DVT), varicose veins, obesity, pregnancy, prolonged standing or sitting, family history, and age over 50.

7 Warning Signs of Chronic Venous Insufficiency

1. Leg Swelling (Edema): One of the most common early signs is swelling in the ankles and lower legs, especially after prolonged standing or sitting. The swelling typically improves overnight when your legs are elevated.

2. Aching, Heaviness, or Fatigue in the Legs: Patients often describe this as a feeling of fullness or pressure in the legs, similar to having weights strapped to them. This typically worsens as the day goes on.

3. Visible Varicose Veins: CVI is the underlying cause of most varicose veins. If you have prominent, rope-like veins on your legs, venous insufficiency is very likely present.

4. Skin Changes Near the Ankles: As CVI progresses, the skin around the ankles can become discolored (reddish-brown), thickened, or leathery. This is called lipodermatosclerosis and is a sign of advanced venous disease.

5. Itching or Skin Irritation: Venous eczema (also called stasis dermatitis) causes itching, redness, and flaking skin near the lower legs and ankles. It's often mistaken for a skin condition rather than a vascular problem.

6. Leg Cramps or Restless Legs: Many patients with CVI experience nighttime leg cramps or a restless, uncomfortable sensation in their legs that makes it difficult to sleep.

7. Venous Ulcers: In advanced CVI, open sores called venous ulcers can develop, typically around the ankle. These wounds are notoriously slow to heal and require specialized medical treatment.

How Is CVI Diagnosed and Treated?

CVI is diagnosed with a duplex ultrasound — a painless imaging test that visualizes blood flow in your veins and identifies valve dysfunction. At Total Vein & Vascular in Arlington, TX, we perform comprehensive venous evaluations using the latest ultrasound technology.

Treatment depends on the severity of your condition. Options include: compression stockings (for mild CVI), radiofrequency ablation or endovenous laser treatment to close diseased veins, sclerotherapy for smaller affected veins, and wound care for venous ulcers. Most patients experience significant symptom relief after treatment.

CVI is a progressive disease — the longer it goes untreated, the more damage it causes.
