Western Summary

Venous stasis refers to stagnation of venous blood and an alteration or reduction of the normal venous flow of blood.

Symptoms

Venous stasis often manifests as edema or swelling and can include the appearance of more prominent, enlarged and/or tortuous veins in the legs, or rarely other locations on the body.

Stasis dermatitis refers to a rash that can subsequently develop due to venous stasis. This is often described as a “ruddy” red-brown, ill-defined pigment that develops on the lower legs. In the acute phase, this can be inflamed and have a more intense red appearance. The rash is often very itchy.

 

Causes

Venous stasis is caused by a combination of ineffective function of the one-way valves in the vein, increased pressure in the veins, and poor function of the calf muscle.  The one-way valves in the veins of the leg may not close all the way, thereby allowing some back flow of fluid leading to increased pressure. If the calf muscle is not active enough it cannot pump the fluids up the leg and against gravity blood tends to pool more in the leg veins. In addition there are several other reasons for increased venous pressure in the body. Examples of this include prolonged standing or certain types of heart failure that result in increased pressure in the venous system. 

Treatments

  • If venous stasis is occurring secondary to a known medical condition (such as heart failure), then there may be medical therapies that can help treat the condition and decrease venous pressure. This can be discussed with your physician to determine if the venous stasis present is due to another treatable condition. 
  • The rash of stasis dermatitis can be treated with topical steroids to reduce the inflammation
  • Compression stockings or socks are often the first treatment for venous stasis. The compression helps to push the blood up the leg. The level of compression should be determined by a health professional as some people are not healthy enough to wear medical grade compression. Stockings and socks come in different “grades” of compression depending on each individual's needs. Compression therapy can be dangerous if the blood flow into the leg is problematic (this is called peripheral vascular disease). Some research suggests that for people with dysfunctional calf muscles, engaging in physical therapy may be helpful.  
  • For some large, dilated veins, or varicose veins, surgical intervention to remove these veins might be possible.
