Venous insufficiency refers to the condition in which inadequate volumes of blood from the legs are returned to the heart.
There is a range of symptoms that includes the following :
Clinical history and physical examination (including examination of leg veins when the patient is sitting and dangling his legs) are usually adequate to allow a tentative diagnosis.
A duplex ultrasound will allow analysis of blood flow through the veins and rule out the differential diagnoses such as a blood clot.
Mild conditions are best handled with self-care steps. These include, but are not limited to the following :
Severe conditions may require more intensive treatments including:
There are several risk factors for chronic venous insufficiency. These include :
Recent studies tend to refute the suggestion that women are more prone to develop this condition compared to men.
Leg veins have valves in them to ensure one-way flow of blood back towards the heart. However, if these valves are damaged or the venous walls are weakened, blood may pool in the veins. Chronic venous insufficiency leads to development of varicose veins (both superficial and deep) and superficial venous reflux. The lack of healthy blood flow leads to edema fluid because of the change in local blood pressure altering the dynamics of flow between vascular and tissue fluids. This poor circulation leads to both inadequate tissue perfusion and removal of wastes with subsequent reduced tissue health. Injuries heal less rapidly and infections (e.g. cellulitis) can become more serious and lead to greater spread .
Healthy lifestyle including adequate exercise and avoiding excessive inactivity is needed to prevent venous insufficiency. Maintaining a healthy weight is also important. Should early signs develop, it becomes important to modify behaviour patterns so that chronic problems do not develop .
Deep veins in the legs have valves in them to ensure a unidirectional flow of blood towards the heart. However, these valves may can become damaged in certain conditions leading to the pooling of the blood in the veins . Early treatment is recommended to prevent chronic insufficiency from developing. It is also known as chronic venous stasis and chronic venous disease.
Venous insufficiency refers to problems associated with inadequate blood returning from the lower legs to the heart. It occurs when the valves in the veins can no longer ensure the one-way flow of blood back to the heart. It is commonly found in ageing patients who spend most of their day inactive. There is a range of symptoms including dull aches, heaviness and cramping in the legs along with itching and tingling. There are changes in skin color along with the development of ulcers in extreme cases. Mild cases can be treated with self-help methods such as compression stockings and lifestyle changes. Exercise and healthy weight are important but resting with the feet above the heart or massage therapy will be beneficial. More severe lesions may need surgery and a variety of techniques are available for different types of chronic venous insufficiency. Maintaining an ideal weight and performing regular exercise are very important in preventing venous insufficiency or restricting it in an early phase.
