Venous stasis

Venous stasis
Other namesVenostasis
Skin changes as a result of long term venous stasis

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

Presentation

Complications

Potential complications of venous stasis are:

Causes

Causes[2] 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.[3]
  • Long periods of immobility that can be encountered from driving,[4] 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.[5][6][7]
  • Weakened Venous valves: these are crucial towards ensuring upward flow to the heart from the lower extremities. If weakened, they may fail to close properly which leads to backwards blood flow/blood pooling. This can lead to slower blood flow in the veins. [8]
