Postthrombotic disease of the lower extremities: causes, treatment
Postthrombotic disease (PTH, postphlebitic syndrome) occurs after the thrombosis of the main veins (on the background of chronic venous insufficiency). The cause of post-thrombotic syndrome and chronic venous insufficiency is a violation of venous outflow due to failure of venous valves. After venous thrombosis, PTH develops gradually. Venous stagnation leads to the formation of edema, changes in the skin and the appearance of trophic ulcers.
Postphlebitic syndrome: symptoms, diagnosis
Clinical manifestations of PTH:
- swelling, heaviness, swelling in the affected leg;
- change in skin pigmentation, congestive dermatitis, itching;
- trophic ulcers in the lower legs and ankles.
Trophic ulcers develop spontaneously or after trauma to the skin. The characteristic localization is the area of the medial bone. Ulcers are wet, painful, sometimes with foul-smelling discharge.
Diagnosis is established on the basis of anamnesis, physical examination and hardware research methods. Duplex scanning allows you to detect the patency of the veins and the condition of the valve apparatus. Contrast phlebography helps determine the nature of blood flow. After assessing the state of the venous system, the phlebologist prescribes treatment.
Treatment of post-thrombotic disease
Conservative therapy of post-thrombotic disease of the lower extremities includes:
- Compression. It is effective for the prevention and treatment of chronic venous insufficiency and PTH. At the first stage, elastic bandages are used. After removing swelling and stabilizing the size of the legs, ready-made compression stockings are used. They provide maximum pressure in the area of the ankle joint, and higher up the leg the pressure gradually decreases. Read more about compression jersey on our website httpswww.dobrobut.com
- Elevated leg position. Raising the limb above the level of the heart reduces venous hypertension and edema. You should lie with your leg elevated for 30-60 minutes at least three times a day.
- Variable pneumatic compression (VPC). Pneumocompression equipment ensures the outflow of blood and lymph from the lower part of the legs.
- Treatment of skin and trophic ulcers using external means.
Doctors recommend regular exercise and weight loss. Nutrition in post-thrombotic syndrome should be low-calorie. You should limit the use of table salt, smoked meats, pickles. In advanced forms, surgical treatment of post-thrombotic disease is indicated.
Prevention, prognosis, complications, disability in post-thrombotic disease
Prevention of PTH consists in adequate anticoagulant therapy after deep vein thrombosis, use of compression knitwear, and lifestyle changes. Patients are recommended regular exercise, hiking, and weight loss.
An important role in post-phlebitic syndrome is played by a timely referral to a specialist in the field of phlebology, as the disease progresses rapidly. PTH significantly reduces the quality of life and can cause disability. The criterion for determining disability in post-thrombotic disease is the nature of trophic ulcers and the presence of erysipelas (erysipelas).
Complications of postphlebitic syndrome arise against the background of injuries, excess weight, surgical interventions on the lower extremities, pregnancy. The main complications of PTH are thrombophlebitis, pulmonary embolism, recurrent erysipelas. Thromboembolism of the pulmonary artery in most cases occurs as a result of thrombosis in the inferior vena cava system. Complications of pyelonephritis depend on the virulence of the streptococcus, the intensity of treatment, and the body's resistance.
