You will find detailed information in our vein dictionary
Post-thrombotic syndrome is a complication with persistent damage in the deep vein system of the legs after deep vein thrombosis has resolved. The thrombosis has damaged or even destroyed the valves in the affected area. The deep veins are no longer able to function properly and chronic stasis (pooling of blood) occurs in the leg. This initially causes a feeling of heaviness or aching in the legs, with swelling and pain. Varicose veins, skin discolouration, chronic inflammation of the skin, and venous leg ulcers may develop with time.
