Chronic venous insufficiency (CVI) is a condition where leg veins fail to return blood to the heart efficiently, causing blood pooling and high pressure in superficial veins — the leading cause of venous ulcers in the lower extremities.
Disease Mechanism:
- Damaged valves: Veins have one-way valves preventing blood reflux. When damaged — from previous DVT, repeated pregnancy, or genetics — blood flows backward.
- Venous hypertension: Blood pressure in leg veins rises above normal (instead of 20-25 mmHg, reaches 80-90).
- Tissue leakage: High pressure pushes fluids, proteins, and red blood cells outside vessels.
- Chronic inflammation: White blood cells activate causing chronic inflammation that destroys tissue.
- Ulcer formation: Thin damaged skin breaks open with minimal injury — starting an ulcer that won't heal.
At BEIT TARIQ Center, we treat the cause (venous pressure) not just the ulcer — with medical compression and advanced dressings.
