Venous stasis

Venous stasis, or venostasis, is a condition of slow blood flow in the veins, usually of the legs.

Complications
Potential complications of venous stasis are:
 * Venous ulcers
 * Blood clot formation in veins (venous thrombosis), that can occur in the deep veins of the legs (deep vein thrombosis, DVT) or in the superficial veins
 * Id reactions

Causes
Causes of venous stasis include:
 * Obesity
 * Pregnancy
 * Previous damage to leg
 * Blood clot
 * Smoking
 * Swelling and inflammation of a vein close to the skin
 * Congestive heart failure.
 * Long periods of immobility that can be encountered from driving, flying, bed rest/hospitalization, or having an orthopedic cast. Recommendations by clinicians to reduce venous stasis and DVT/PE often encourage increasing walking, calf exercises, and intermittent pneumatic compression when possible.
