Chronic venous insufficiency (CVI)

Chronic venous insufficiency: causes, symptoms, and treatment methods

Information about Chronic Venous Insufficiency (CVI)

Chronic venous insufficiency (CVI) is a condition in which the venous valves do not function adequately, leading to the reverse flow of blood into the veins and worsening venous blood flow. This disorder most commonly affects the lower extremities and can manifest as swelling, pain, skin trophic changes, and ulcers.

The main causes of CVI are congenital anomalies of the venous valves, venous thromboses, as well as prolonged standing or sitting positions, which increase pressure in the veins of the lower extremities and contribute to the development of the disease. Treatment of CVI may include conservative methods such as compression therapy and physical exercises, and in some cases, surgical intervention may be necessary to restore normal blood flow in the veins.

Etiology of Chronic Venous Insufficiency (CVI)

Chronic venous insufficiency (CVI) is caused by various factors, including congenital abnormalities of the venous valves, trauma to the venous system, inflammatory processes and diseases, as well as structural changes in the walls of the veins. Circulatory disorders, such as venous thrombotic pain and blood stagnation in the veins, can also contribute to the development of CVI.

In addition, risk factors include aging of the body, metabolic disorders, obesity, pregnancy, prolonged standing or sitting, as well as genetic predisposition. It is important to recognize that CVI is a multifactorial disease that requires a comprehensive approach to diagnosis and treatment, including identifying the underlying causes and preventing disease progression.

  • Congenital anomalies of venous valves: Hereditary defects in the development of valves can lead to insufficient venous blood flow.
  • Injuries to the venous system: Damage to veins can disrupt normal blood flow and contribute to the development of chronic venous insufficiency (CVI).
  • Diseases and inflammatory processes: Inflammation of the veins can lead to changes in their structure and function, causing CVI.
  • Venous thrombotic pain: The formation of blood clots in the veins can restrict or block blood flow, worsening venous stasis and promoting the development of CVI.
  • Aging of the body: With age, the tone of the vessel walls decreases, which can increase the risk of developing CVI.

The clinical picture of Chronic Venous Insufficiency (CVI)

Chronic venous insufficiency (CVI) manifests with a variety of symptoms, including swelling of the lower limbs, fatigue and heaviness in the legs, itching and cramps, worsening skin color, and the appearance of venous ulcers. Patients may also experience pain in the area of the shins, which worsens when standing or sitting and improves when elevating the legs. Decreased muscle volume and changes in the skin, such as dryness and hyperpigmentation, are also characteristic of CVI.

Significant dilation of superficial veins, the appearance of reticular veins on the legs, and swelling around the shins and ankles are also typical signs of CVI. For accurate diagnosis and treatment, it is important to consider all these nuances of the clinical picture, as CVI is a chronic condition that requires a comprehensive approach to managing symptoms and preventing complications.

  • Swelling of the lower limbs: caused by the stagnation of venous blood and a decrease in blood pressure, which leads to fluid retention in the tissues.
  • Tiredness and heaviness in the legs: arise from impaired circulation and swelling, which increases the load on the lower limbs.
  • Cramps and itching: can manifest as a result of circulation disorders and increased skin sensitivity.
  • Ulcers and changes in the skin: worsening blood supply can lead to the formation of venous ulcers and changes in the skin, such as dryness and flaking.
  • Pain and discomfort in the shin area: are usually characterized as dull, heavy pain that intensifies after periods of standing or sitting and improves when lying down.

Expert opinion on the treatment of Chronic Venous Insufficiency (CVI)

Experts’ opinions on the treatment of Chronic Venous Insufficiency (CVI) emphasize the importance of an individualized approach for each patient, depending on the severity and characteristics of the disease. The standard method for treating CVI may include conservative treatment involving the use of compression garments, lifestyle modification recommendations, and physical exercises. Experts also highlight the importance of weight and diet management, as obesity and poor nutrition can exacerbate symptoms.

In cases where conservative treatment does not yield the desired effect or complications arise, specialists may recommend surgical treatment methods, such as sclerotherapy, laser therapy, treatment of venous ulcers, or in some cases, surgical removal of the affected veins. Experts urge patients with CVI to seek medical consultation for individualized planning of the optimal treatment pathway and to prevent the progression of the disease.

Methods for diagnosing Chronic Venous Insufficiency (CVI)

For the diagnosis of Chronic Venous Insufficiency (CVI), various methods are used, including clinical examination, medical history, laboratory tests, functional tests, duplex ultrasound scanning, and phlebography. A physician’s clinical examination allows for the identification of characteristic symptoms and signs of CVI, such as swelling, changes in the skin and veins, a prominent venous network, and ulcers.

Duplex ultrasound scanning is widely used for visualizing the condition of veins and valves, assessing blood flow, and identifying possible thrombosis or disturbances in venous blood flow. These diagnostic methods not only allow for the detection of CVI but also help determine the severity of the disease and the underlying causes, which is crucial for selecting the optimal treatment plan.

  • Clinical examination and history: The doctor examines the patient, identifies characteristic symptoms of chronic venous insufficiency, and inquires about medical and family history of diseases.
  • Ultrasound duplex scanning: A non-invasive method that allows visualization of the condition of veins, determining the presence of blood clots and assessing blood flow.
  • Functional tests: Include methods such as rheography and duplex scanning when performing special tests to evaluate the functional activity of veins and valves.
  • Laboratory studies: May include blood tests to assess biochemical parameters and examinations for clotting disorders.
  • Phlebography: Used to assess the structure of the venous system and blood flow, detect pathological changes, and choose further treatment strategies.

Approaches to the therapy of Chronic Venous Insufficiency (CVI)

The treatment of chronic venous insufficiency (CVI) aims to reduce symptoms, improve the patient’s quality of life, and prevent complications. The main therapeutic methods include conservative approaches such as compression therapy, pharmacological treatment, regular exercises to strengthen muscles, and maintain blood circulation. In some cases, surgical intervention may be required to correct defects or restore venous blood flow.

Individualization of therapy is important, as each patient with CVI may have specific needs and risk factors. A multimodal approach, combining various treatment methods tailored to an individual care plan, is an effective way to manage CVI and ensure improvement in patients’ conditions.

  • Compression therapy: includes the use of compression stockings or bandages to improve venous blood flow and reduce swelling.
  • Pharmacological treatment: the use of medications such as venotonics, anticoagulants, and anti-inflammatory drugs to improve the condition of the veins and reduce inflammation.
  • Physical activity: regular exercises, especially exercises for the lower limbs, help strengthen muscles and improve blood flow in the veins.
  • Lifestyle changes: include proper nutrition, weight control, avoiding prolonged standing or sitting, and elevating the legs at rest.
  • Surgical treatment: may include sclerotherapy, laser therapy, vein stripping, or vein grafting to improve venous blood flow in cases where conservative methods are ineffective.

Prevention measures for Chronic Venous Insufficiency (CVI)

The prevention of chronic venous insufficiency (CVI) includes a number of important activities to maintain the health of the venous system. Regular physical exercises, as active muscle work, contribute to stimulating blood circulation and strengthening the muscles of the lower limbs, which helps to prevent blood stasis and the development of CVI. Adhering to a healthy lifestyle, including proper nutrition, weight control, and avoiding prolonged static positions, also plays a key role in the prevention of CVI.

One important aspect of CVI prevention is wearing compression garments, which help maintain proper blood flow in the veins and reduce swelling. Regular medical examinations to detect early signs of venous diseases also facilitate timely intervention and prevent the development of CVI. Overall, timely and regular preventive measures, taking into account the individual characteristics of the patient, will help reduce the risk of occurrence or progression of chronic venous insufficiency.
