Venous Disease and Pulmonary Embolism
Venous disease refers to a group of conditions that affect the veins, the blood vessels that return deoxygenated blood back to the heart. When veins become damaged or weakened, it can lead to poor circulation, particularly in the lower limbs. The most common forms of venous disease include chronic venous insufficiency (CVI), varicose veins, deep vein thrombosis (DVT), and venous ulcers.Chronic venous insufficiency occurs when the valves in the veins are not functioning properly, causing blood to pool in the legs. This leads to swelling, heaviness, aching, skin changes, and, in advanced cases, ulceration. Varicose veins are enlarged, twisted superficial veins visible under the skin and are often due to valve failure.
Deep vein thrombosis (DVT) is a serious condition where a blood clot forms in a deep vein, typically in the legs. This can cause pain, swelling, redness, and warmth in the affected limb. If left untreated, the clot can travel to the lungs and cause a pulmonary embolism (PE), which is a medical emergency.Venous disease is often caused or aggravated by factors such as prolonged standing or sitting, obesity, pregnancy, aging, family history, smoking, and prior vein damage. It is diagnosed through duplex ultrasound, venography, or D-dimer tests (for clotting).
Treatment includes compression therapy, lifestyle changes, anticoagulant medications, sclerotherapy, laser treatments, and surgical interventions like vein stripping or ablation. Preventive measures include staying active, elevating the legs, and avoiding prolonged immobility.
