Venous insufficiency is a condition characterized by inadequate venous outflow, resulting in blood stagnation in the veins, especially in the lower extremities. This leads to various clinical manifestations, including edema, varicose veins, skin discoloration, and in advanced cases, trophic ulcers and thrombophlebitis. The main mechanisms of this disease are venous valve dysfunction and increased venous pressure. The main forms of venous insufficiency include chronic venous insufficiency (CVI) and acute venous thromboembolism. The disease has a significant impact on the quality of life of patients, increasing the risk of developing serious complications such as thromboembolism and deep venous thrombophlebitis.
History of the disease and interesting historical facts
Venous insufficiency has been known for centuries. Historical records show that as early as ancient Egypt, physicians described conditions associated with edema and circulatory problems. In the Middle Ages, advances in anatomy and physiology led to a clearer understanding of the venous system and the causes of diseases associated with it. An important step in the study of venous insufficiency was the discovery of valves in the veins, which was confirmed in the 17th century by the English anatomist William Harvey while studying blood circulation. In the 19th century, venous insufficiency became the subject of more detailed study, which led to the development of treatment methods, including surgical interventions. In recent decades, interest in non-invasive diagnostic and treatment methods has increased significantly, which has significantly improved patient outcomes and quality of life.
Epidemiology
According to the World Health Organization, chronic venous insufficiency is one of the most common diseases of the vascular system. Approximately 20-30% of the adult population in developed countries suffers from various forms of venous insufficiency, with women being more than twice as likely to be affected than men. The highest incidence is observed in people over 50 years of age. In addition, in recent years, there has been a tendency for the disease to become more common among younger people, which is associated with lifestyle changes and associated risk factors, such as a sedentary lifestyle, working on one’s feet, and obesity.
Genetic predisposition to this disease
Research shows that venous insufficiency has a genetic component. Various genes are being considered that may influence the condition of the venous walls and the functioning of the venous valves. For example, the COL3A1 gene, which is responsible for collagen synthesis, has been associated with a predisposition to varicose veins. Also of importance is the MTHFR gene, which is involved in folate metabolism and has been found to influence serum homocysteine levels, which is associated with venous thromboembolism. Genetic mutations and polymorphisms may increase the risk of developing venous insufficiency, especially when combined with external factors such as lifestyle and environment.
Risk factors for the development of this disease
Important risk factors for venous insufficiency are:
- Genetic predisposition
- Obesity and overweight
- Lack of physical activity and sedentary lifestyle
- Prolonged standing (for example, in medical workers, salespeople)
- Pregnancy and hormonal changes
- Injuries and surgeries on the lower extremities
- Smoking and alcohol abuse
It is important to note that the combination of several risk factors significantly increases the likelihood of developing venous insufficiency.
Diagnosis of this disease
Diagnosis of venous insufficiency begins with a clinical examination, where the main symptoms are:
- Swelling of the lower extremities
- Pain and discomfort in the legs, especially after standing or sitting for long periods of time
- Varicose veins
- Skin changes: hyperpigmentation, eczema, trophic ulcers
Laboratory tests may include homocysteine levels, coagulation, and other parameters related to venous thromboembolism. Radiological imaging, such as venous duplex ultrasound, is the standard in diagnosing venous insufficiency, allowing visualization of the venous system and detection of thrombi. CT and MRI may also be used to evaluate more complex cases. Differential diagnosis is important to exclude other conditions, such as arterial insufficiency, lymphedema, and other vascular pathologies.
Treatment
Treatment of venous insufficiency is usually comprehensive and includes:
- Conservative methods: compression (for example, using compression hosiery), regular physical activity, lifestyle correction;
- Pharmacological treatment aimed at improving venous tone and reducing edema. For example, phlebotonics (Detralex, Venoruton) and anti-inflammatory drugs;
- Surgical treatment, including phlebectomy, sclerotherapy and laser coagulation of veins;
- Modern techniques such as endovenous laser ablation (EVLA) allow varicose veins to be closed without major surgery.
It is important that the choice of treatment method depends on the stage of the disease, the presence of concomitant diseases and the general condition of the patient.
List of medications used to treat this disease
The most commonly used drugs for the treatment of venous insufficiency include:
- Detralex – phlebotonic, improves venous tone;
- Venoruton – venoprotector, helps improve venous outflow;
- Troxerutin – phlebotonic, reduces swelling;
- Aspirin – can be used to prevent thrombosis;
- NSAIDs – to relieve inflammation and pain.
The choice of drugs depends on the individual characteristics of the patient and the stage of the disease.
Disease monitoring
Monitoring venous insufficiency involves regular check-ups with a doctor and evaluation of the effectiveness of treatment. Control stages may include:
- Assessment of clinical symptoms;
- Regular ultrasound examinations to assess the condition of the veins;
- Compliance with lifestyle recommendations and drug therapy;
- Strategies for the prevention of thrombosis and complications.
The prognosis with timely and adequate treatment is generally favorable, but some patients may develop complications such as trophic ulcers or thrombophlebitis, which require more intensive treatment.
Age-related features of the disease
Venous insufficiency can occur in different age groups, although it is most common in people over 50 years of age. Younger people, especially pregnant women, may also experience venous insufficiency due to hormonal changes and increased blood volume. In older people, the condition may be more severe due to underlying medical conditions such as diabetes or hypertension. Treatment and prevention of venous insufficiency depend on the patient’s age and the presence of chronic diseases.
