Chronic venous insufficiency – cause, symptoms and modern treatment
Chronic venous insufficiency (CVI) is the underlying disease behind varicose veins, leg swelling and venous leg ulcers. Early duplex ultrasound assessment and endovenous laser ablation (EVLT) halt the progression and relieve symptoms.
What is venous insufficiency?
The valves in the leg veins no longer close properly. Blood flows backwards (reflux), pressure rises and the veins dilate – from spider veins through varicose veins to skin changes and leg ulcers.
Symptoms
- Heavy, tired legs late in the day.
- Ankle swelling.
- Nocturnal calf cramps and restless legs.
- Itching and brown discoloration around the ankle.
- Visible varicose veins or spider veins.
CEAP classification
CVI is staged from C0 (no visible signs) to C6 (active venous leg ulcer). Treatment is generally indicated from C2 with symptoms or from C3.
Diagnosis
Diagnosis is made with duplex ultrasound performed standing – a painless 20–30 minute exam that maps reflux in each vein.
Treatment
First-line treatment is endovenous laser ablation (EVLA/EVLT), which seals the diseased vein from within. Conservative treatment with class 2 compression stockings, exercise and elevation relieves symptoms but does not cure the disease.
