D is a dimer.

Today, medicine has stepped far ahead. New drugs, new ways and methods of diagnosis, new approaches to treatment.

The discovery of modern diagnostic methods allows to identify emerging diseases at earlier stages and to conduct their effective treatment.

Thrombosis of the deep veins of the extremities (mainly the lower extremities), as well as the complications of this disease, which are most often manifested by thromboembolism. The consequences of the latter are often fatal (with PE), thromboembolism of the intestinal arteries or kidneys leads to a deterioration in the quality of life of the patient due to persistent pain and the need for surgery. The effectiveness of surgical intervention in this case is extremely low in the case when thrombi still continue to break away from the walls of blood vessels.

This problem is most relevant for the elderly in the postoperative period, especially if the operative intervention was carried out on the pelvic organs.

The appearance of new indicators, such as D-dimer, allowed to improve and optimize diagnostic manipulations.

Dimer indicates the ability of a person's blood to clot. Thus, when the dimer decreases, the activity of thrombus formation decreases and the coagulation activity of the system decreases. An increase in the value of this indicator indicates an increased fibrinolysis (which can be caused by hemorrhagic complications, rheumatoid factor, as well as various infections).

D - dimer is, first of all, an indicator that is the main one in diagnosing thrombosis of any etiology.

The analysis is carried out in the morning, on an empty stomach.

In the definition of such an indicator as D-dimer, in the first place, people who suffer from coronary heart disease, lipid metabolism disorders, as well as persons with hypertensive disease need it.

It is timely to assign these analyzes to patients and without corresponding disorders. So the analysis on D - dimer is performed when preparing for surgery, as well as for pregnant women. I would like to note that at the present stage the old routine methods of determining thrombotic activity have lost their diagnostic value. Today, clinicians around the world are using a new modern method for diagnosing thrombosis, which, in terms of informativeness, is not only inferior to the old, but also much higher than them.

D - dimer is formed during the cleavage of polymer-bound fibrin, the formation of which occurs under the influence of thrombin. The duration of the dimer in the blood is about six hours, which is very convenient for diagnosing pathologies from the coagulation system of the blood.

D - dimer was elevated at values greater than five hundred nanograms of FEU / ml. In this case, the risk of developing thrombosis is extremely high and a complex of therapeutic measures is required to restore the normal state of the coagulation system.

This indicator is indispensable in the diagnosis of deep vein thrombosis of the extremities, embolism (thrombi) of various arteries (pulmonary, intestinal, renal and others).

In addition, based on the determination of the dimer level, this diagnostic method makes it possible to identify various complications of pregnancy (caused by a change in the rheological properties of the blood), as well as the syndrome of disseminated intravascular coagulation.

Thus, the emergence of new diagnostic methods allowed not only to simplify the latter and increase their informativeness, but also led to an increase in the detection of certain pathologies in the early stages. The latter led to an increase in the effectiveness of the therapy, as well as to the improvement of methods for preventing thrombotic complications (after surgery or pregnancy).
