The most common cause of chronic venous insufficiency is reflux of the venous valves of superficial veins. This may in turn be caused by several conditions: Deep vein thrombosis (DVT), that is, blood clots in the deep veins. Chronic venous insufficiency caused by DVT may be described as postthrombotic syndrome.

After 4 years, patients with chronic venous insufficiency with lupus anticoagulant were found to develop a venous leg ulceration more frequently compared to those without (p = 0.01), suggesting that lupus anticoagulant may play an important role in the pathogenesis of chronic venous insufficiency.

One common cause is venous insufficiency, in which damage to valves in the legs' deep veins hinders the return of blood to the heart. This causes fluid to collect and pool in the legs and feet. Superficial varicose veins can also cause legs to swell.

However, what they do know is that varicose veins can contribute to venous hypertension. When blood pools in the veins in your lower extremities, that puts additional pressure on your heart, which has to then work harder to pump all of that pooled blood back up the body.

Conditions associated with PVD that affect the veins include deep vein thrombosis (DVT), varicose veins, and chronic venous insufficiency. Lymphedema is an example of PVD that affects the lymphatic vessels. When PVD occurs in the arteries outside the heart, it may be referred to as peripheral arterial disease (PAD).

These venous problems lead to pooling of the blood in the legs or obstructed veins. Without proper blood flow in these areas, extra fluid can begin to build in the tissue. This pressure can cause puffiness in one leg or both, often restricting the range of motion in the ankles and feet.

In advanced cases, breakdown of the skin may cause bleeding from varicose veins, and large varicosities may develop blood clots, a condition called superficial phlebitis or thrombophlebitis. If you experience any of these symptoms, talk with your doctor. Do not ignore these symptoms.

Symptoms of chronic venous insufficiency may include: Swelling in your legs or ankles. Tight feeling in your calves or itchy, painful legs. Pain when walking that stops when you rest.

Chronic venous insufficiency is caused by malfunction of the venous system associated with chronic venous hypertension. When the venous system is normal, exercise such as walking activates the calf muscle pump, reducing the venous pressure in the foot from 90 mm Hg on standing to around 30 mm Hg during walking.

Although arterial and venous insufficiency share many of the same characteristics and symptoms, the two conditions are actually quite different. Venous insufficiency refers to a breakdown in the flow of blood in our veins, while arterial insufficiency stems from poor circulation in the arteries.

Individuals suffering from venous insufficiency may also experience edema. “Usually, individuals who suffer from heaviness and leg swelling make the mistake of not drinking enough water – says Dr.

In venous insufficiency, the valves are damaged, and blood backs up and pools in the vein. Fluid may leak out of the vein and into the surrounding tissue. This can lead to a breakdown of the tissue and an ulcer. Veins that become blocked also may cause fluid to pool, leading to these ulcers.
