Venous stasis
Venous Stasis
Venous stasis (pronunciation: /ˈviːnəs ˈsteɪsɪs/), also known as venostasis, is a medical condition characterized by slow or stagnant blood flow in the veins, typically in the legs.
Etymology
The term "venous stasis" is derived from the Latin word "vena" meaning vein, and the Greek word "stasis" meaning standing still.
Definition
Venous stasis refers to the condition where the flow of blood through the veins is slow or stagnant. This is often due to a dysfunction in the venous valves, which prevent the backflow of blood. When these valves fail, blood can pool in the veins, leading to venous stasis. This condition is most commonly seen in the legs and can lead to complications such as venous ulcers, deep vein thrombosis, and chronic venous insufficiency.
Symptoms
Symptoms of venous stasis may include swelling, pain, skin changes, and ulcers in the affected area. The skin may become discolored, thickened, and itchy. In severe cases, non-healing ulcers may develop.
Causes
Venous stasis is often caused by conditions that affect the veins and blood flow, such as varicose veins, deep vein thrombosis, and chronic venous insufficiency. Other factors that can contribute to venous stasis include obesity, pregnancy, age, prolonged standing or sitting, and a history of blood clots.
Treatment
Treatment for venous stasis aims to improve blood flow in the veins. This may involve lifestyle changes, such as regular exercise and elevation of the legs, as well as medical treatments like compression therapy, medication, and in some cases, surgery.
