[Prevention of thromboembolic complications in surgery]

It is known that during the postoperative period about 25-50% operated patients develop postoperative venous thrombosis. The mechanism of development of postoperative thrombosis is promoted in surgical patients by the so-called "wound healing process" with an enhanced synthesis of fibrinogen, inhibitors of fibrinolysis and other proteins of the acute phase for release of various cytokins (IL-1, IL-6, TNF, TGF and others). The development of thrombosis is promoted also by other risk factors: advanced age, extensive surgical trauma, infection, immobility, obesity etc. Preventive administration of so-called small doses a of heparin or rather so-called low molecular heparin (LMWH) substantially reduces the risk. The authors submit also a list of drug with an antithrombotic action and rheologics.
