Chronic venous insufficiency happens when the veins in your legs struggle to pump blood back to your heart efficiently. This condition is caused by weakened or damaged vein valves that disrupt normal blood flow. As blood pools in the veins, pressure increases, leading to swelling, pain, skin changes, and other complications. Risk factors include genetics, aging, obesity, pregnancy, prolonged standing or sitting, and a history of blood clots.

What are the Types of Chronic Venous Insufficiency?

Chronic venous insufficiency includes several manifestations of poor venous circulation that affect the legs and surrounding tissues.

Varicose Veins: Enlarged, twisted veins that appear as bulging, rope-like structures beneath the skin.
Venous Stasis Ulcers: Open sores on the lower legs caused by long-term poor blood circulation.
Edema: Swelling of the legs due to fluid accumulation from impaired venous return.
Skin Changes: Brown discoloration, itching, dryness, and thickening of the skin around the ankles and lower legs.
Lipodermatosclerosis: Chronic inflammation and hardening of the fatty tissue beneath the skin, causing pain and tightness.

What are the Symptoms of Chronic Venous Insufficiency?

Symptoms develop gradually and often worsen after prolonged standing or sitting.

Leg swelling, especially around the ankles.
Leg pain, aching, or cramping.
Heaviness or fatigue in the legs.
Varicose veins.
Skin discoloration or thickening.
Itching around the affected veins.
Venous leg ulcers.
Warmth or throbbing sensation in the legs.

What are the Causes of Chronic Venous Insufficiency?

Chronic venous insufficiency develops when the valves in the leg veins fail to function properly, allowing blood to flow backward and pool in the veins.

Deep vein thrombosis.
Damaged or weakened venous valves.
Obesity.
Prolonged standing or sitting.
Advancing age.
Previous leg injuries or surgeries.
Pregnancy.
Family history of venous disease.

When to See a Doctor for Chronic Venous Insufficiency?

If you experience persistent leg swelling, aching, heaviness, varicose veins, skin discoloration, or non-healing leg ulcers, consult a Vascular Endovascular Surgeon. Early diagnosis and treatment can improve blood circulation, relieve symptoms, prevent complications, and reduce the risk of chronic venous ulcers.

If you have persistent leg pain, heaviness, swelling, or cramping that worsens after prolonged standing or sitting.
If you notice enlarged or painful varicose veins, skin discoloration, or thickening around the ankles.
If you develop itching, redness, or eczema-like changes on the lower legs.
If you have a leg wound or ulcer that does not heal or repeatedly returns.
If you experience bleeding from a varicose vein or sudden worsening of leg swelling and pain.
If you develop warmth, redness, or tenderness in the leg, which may indicate a blood clot and requires urgent medical attention.
