What is Chronic Venous Insufficiency?

Chronic venous insufficiency (CVI) is a vascular condition that affects many people - left untreated it can lead to discomfort and potential complications such as venous ulcers. CVI occurs when the veins in the legs fail to efficiently pump blood to the heart. This can result from damaged vein valves or weakened vein walls, causing blood to pool in the lower legs, causing discomfort, pain and swelling.

Causes of Chronic Venous Insufficiency

Several factors contribute to the development of CVI:

  • Varicose Veins: These are enlarged, twisted veins that become incompetent over time as blood fails to pump up to the heart.
  • Deep Vein Thrombosis (DVT): Blood clots in deep veins can damage vein valves.
  • Prolonged Standing or Sitting: Occupations that require lots of standing or lots of sitting can increase venous pressure.
  • Obesity: Excess weight puts additional pressure on the circulatory system.
  • Pregnancy: Increased blood volume and hormonal changes can affect vein function.

Recognising the Symptoms

Early detection of CVI is crucial. Common symptoms include:

  • Legs Aching: Persistent discomfort or heaviness in the legs.
  • Feet Swelling: Noticeable swelling, especially after long periods of standing.
  • Skin Changes: Discolouration or the appearance of blood vessels on the skin.
  • Ulcers: Non-healing wounds, typically around the ankles.

Treatment Options To Fix Chronic Venous Insufficiency

Addressing CVI involves could involve a combination of lifestyle changes and medical interventions:

  • Compression Therapy: Wearing compression stockings can alleviate symptoms by promoting blood flow.
    •  
  • Minimally Invasive Procedures: Techniques such as varicose vein treatment or endovenous radiofrequency ablation can close or remove malfunctioning veins.
  • Foam Sclerotherapy: Injection of a harmless chemical solution that seals off faulty veins to help promote blood flow to healthier veins.

Seeking a diagnostic assessment with a vascular specialist is essential to determine the most appropriate treatment plan. At UK Vein Clinic, our team is dedicated to providing personalised care to address your unique needs.
