Veenmisfunktsiooni

Veenmisfunktsiooni, often referred to as venous insufficiency, is a medical condition where the veins have difficulty returning blood to the heart. This typically affects the veins in the legs. The valves within the veins, which are designed to prevent blood from flowing backward, become weakened or damaged, leading to a pooling of blood.

Several factors can contribute to the development of veenmisfunktsiooni. These include a history of blood clots in the legs (deep vein thrombosis), obesity, prolonged standing or sitting, pregnancy, and a family history of the condition. Age also plays a role, as vein walls and valves can weaken over time.

The symptoms of veenmisfunktsiooni can vary in severity. Common signs include swelling in the legs and ankles, particularly at the end of the day, aching or heaviness in the legs, itching, and leg cramps. In more advanced cases, skin changes may occur, such as discoloration, thickening, and the development of varicose veins or venous ulcers.

Diagnosis is usually made through a physical examination and by reviewing the patient's medical history. An ultrasound of the legs, known as a duplex ultrasound, is often used to assess blood flow and identify any valve dysfunction or blockages.

Treatment aims to manage symptoms and prevent complications. Lifestyle modifications such as regular exercise, weight management, and avoiding prolonged periods of standing or sitting are often recommended. Compression stockings are a common and effective treatment, applying external pressure to the legs to assist blood flow. In some instances, medication or surgical interventions may be considered to address underlying issues or treat complications like ulcers.
