Venous stasis refers to the slowing or pooling of blood in the veins, typically in the lower extremities. It is a condition that can lead to various complications, including chronic venous insufficiency, varicose veins, and venous ulcers.

Pathophysiology

Venous stasis occurs when the normal flow of blood through the veins is disrupted. This can be due to:

• Venous valve incompetence: When the valves in the veins fail to function properly, blood can flow backward, leading to pooling.
• Obstruction: Physical blockages in the veins, such as deep vein thrombosis, can impede blood flow.
• Muscle pump dysfunction: The calf muscles act as a pump to help return blood to the heart. If this mechanism is impaired, venous stasis can occur.

Clinical Manifestations

Patients with venous stasis may present with:

• Edema: Swelling of the lower legs and ankles due to fluid accumulation.
• Skin changes: Hyperpigmentation, lipodermatosclerosis, and atrophie blanche.
• Pain and heaviness: A feeling of heaviness or aching in the legs, especially after prolonged standing.
• Ulceration: Chronic venous ulcers, typically around the ankles.

Diagnosis

The diagnosis of venous stasis is primarily clinical, based on the patient's history and physical examination. However, additional tests may include:

• Doppler ultrasound: To assess blood flow and check for valve incompetence or thrombosis.
• Venography: An imaging test to visualize the veins.

Management

Management of venous stasis involves both conservative and interventional approaches:

• Compression therapy: The use of compression stockings to improve venous return.
• Elevation: Elevating the legs to reduce swelling.
• Medications: Diuretics and venoactive drugs may be used.
• Surgical interventions: Procedures such as vein stripping, sclerotherapy, or endovenous laser treatment.

Prevention

Preventive measures include:

• Regular exercise: To improve circulation and muscle tone.
• Weight management: To reduce pressure on the veins.
• Avoiding prolonged standing or sitting: To prevent blood pooling.
