Venous insufficiency

disease process in which there is a process of valve insufficiency of deep veins of a person. The disease is widespread, but it has received little attention, both by patients and professionals in the field of medicine. In the conditions of modern life, which is accompanied by lack of exercise, a long stay in a sitting or standing position during operation, special features of the system of blood vessels that are congenital in nature, can lead to problems of blood flow in the veins.

Reasons

Valves, which are the main substrate of the disease, there are superficial and deep veins of the man. In the case of deep vein thrombosis is blockage of the venous lumen. Over time, the lumen can be restored by recanalization. However, the normal operation of the venous valves is not renewed after the restoration of gaps in the affected veins. This results in fibrosis of the dryer, their elasticity is reduced. The result is the destruction of venous valves and the deviation in the process flow.

The main purpose of the venous valves prevent backflow of blood in the region of the veins. In the case of the progress of valve disease is the development postthrombophlebitic syndrome. The main manifestation of this syndrome is venous insufficiency of the lower extremities. There are many clinical manifestations of this disease. The main signs of venous insufficiency pain in the legs, feeling of heaviness in the lower extremities. Also there is swelling in the evening hours, passing to the offensive in the morning. Perhaps the presence of seizures, altered skin color in the lower third of the leg of the patient, reduced skin elasticity, varicose veins. In some cases, varicose veins are not a symptom of the initial stage of development of venous insufficiency.

Chronic venous insufficiency occurs due to the influence of factors that can lead to progress of varicose veins, thrombosis of the deep veins of the lower extremities. Also to the development of disease may result in the insufficiency of venous valves of the primary or secondary forms.

Symptoms

Due to the damage of venous valves is a disruption of blood flow because damaged valves can’t prevent reverse move of blood in the veins. The result is an increase in blood pressure, leading to the penetration of plasma into the tissues surrounding the vein, which develops edematous process. The main symptoms of venous insufficiency include venous ulcers occur in the affected veins, which is manifested as a result of ischemia developed due to the compression of small vessels of the skin.

In addition, the symptomatic picture of the disease include pain, bearing arching dull character. Increased pain with prolonged load on the lower limbs and weaker during rest. Symptoms also include the occurrence of leg cramps at night, symptoms of dermatitis, eczema, pigmentation of the skin in the lower parts of the tibia.

Diagnosis

The process of setting is based on the methods using ultrasound and radiography. Diagnostic measures include the following methods

  • ultrasound method for Doppler
  • duplex scanning with ultrasound
  • venography.

Treatment

Chronic venous insufficiency of the lower extremities treated using the methods used in the development of other diseases of the vascular system, for example, postthrombophlebitic syndrome or varicose veins. Treatment of chronic venous insufficiency includes both surgical and non-surgical methods.

The degree of venous insufficiency have a direct impact on which treatment is applied in the first place.

Treatment of chronic venous insufficiency of the lower extremities includes compression therapy. For the compression methods are mainly used ACE bandages, but in most cases use special jerseys. The basis of operation of a compression therapy the compression of the veins of the lower extremities, which are located in the surface region, which prevents the outflow of blood from the deep veins. The degree of pressure allows to distinguish four degrees of compression bandages and hosiery.

Sclerotherapy is also used by typing in the vein of special products is called a chemical burn of the walls, leading to hardening of the vessel walls. Today, together with sclerosant apply compression stockings action. The duration of treatment lasts up to three months. The only drawback of this treatment is the possibility of progress of varicose recurrence. This method develops starting from 1967.

Surgical methods include surgery Linton Cocket in which the tibia is cut and is done ligation of perforating veins type. Today, this method is modified to enable ligation with the minimum size of the incision of the lower leg.

Another surgical method operation Troyanov-Trendelenburg, the result of which tied the junction of the saphenous vein of the thigh with the femoral vein. Also removed a conglomerate of veins affected with varicose.

Prevention

Prevention of venous insufficiency is the prevention of diseases, which cause its development. One of the important methods of prevention is to wear compression hosiery.
