Chronic Venous Insufficiency

Chronic Venous Insufficiency (CVI) is a persistent medical condition in which the leg veins fail to pump blood back to the heart efficiently. It primarily occurs due to damaged or weakened valves in the veins, which interrupt the normal upward flow of blood against gravity. In a healthy vein, the one-way valves keep blood moving towards the heart and prevent backflow. However, when these valves are compromised, it can lead to CVI. Blood can pool in the lower limbs, causing a variety of symptoms like swelling, pain, skin changes, and, in severe cases, ulcers.

What are the symptoms of chronic venous insufficiency?

  • swelling in the legs and ankles
  • pain or aching sensation in the affected leg
  • itching or tingling
  • skin discoloration or changes
  • leg cramps or restless legs

What are the risk factors for chronic venous insufficiency?

The condition is often a result of deep vein thrombosis (blood clots in the deep veins) or phlebitis (inflammation of the veins). Several factors contribute to an increased risk of developing Chronic Venous Insufficiency:

  • Age: The likelihood of CVI tends to rise with age.
  • Family history: A genetic predisposition may increase the susceptibility to venous insufficiency.
  • Gender: Women, especially those who have been pregnant multiple times, are more prone to developing CVI.
  • Obesity: Excess weight places additional pressure on the veins, potentially leading to venous insufficiency.
  • Prolonged standing or sitting: Occupations or lifestyles that involve extended periods of standing or sitting can contribute to CVI.

The significance of early diagnosis

Timely diagnosis of Chronic Venous Insufficiency is vital as it allows for proactive management to prevent complications. If left untreated, CVI can lead to more severe conditions such as venous ulcers or deep vein thrombosis.

What are the diagnostic methods for chronic venous insufficiency?

Several diagnostic methods are employed to identify and assess Chronic Venous Insufficiency:

Physical Examination

Healthcare professionals may examine the legs for swelling, skin changes, or other visible signs.

Duplex Ultrasound

This non-invasive test uses sound waves to visualize blood flow in the veins, helping to identify any abnormalities.


A contrast dye is injected into a large vein, and X-rays are taken to reveal the blood flow within the veins.

Is chronic venous insufficiency curable?

While Chronic Venous Insufficiency may not be completely curable, various treatment options aim to manage symptoms and prevent the progression of the condition. The primary goals of treatment include improving blood flow and relieving symptoms.

Treatments for chronic venous insufficiency

Treatment options for CVI encompass lifestyle modifications, conservative measures, and, in some cases, medical interventions:

Compression Therapy

Wearing compression stockings helps enhance blood flow and reduce swelling.

Elevation Of Legs

Keeping the legs elevated helps alleviate swelling and promotes blood circulation.


Certain medications may be prescribed to manage symptoms.

Endovenous Ablation

This minimally invasive procedure uses heat or laser energy to close off damaged veins.


A liquid or foam solution is injected into the affected veins to close them off.


Varithena is a type of foam sclerotherapy treatment that collapses varicose veins using a medication called polidocanol.
