[Decreased retraction of blood clots in patients with venous thromboembolic complications].

Haemostatic disorders play an important role in the pathogenesis of acute venous thrombosis. One of the least studied reactions of blood coagulation and thrombogenesis is spontaneous contraction of blood clots, which takes place at the expense of the contractility apparatus of activated blood platelets adhered to fibrin fibres. The work was aimed at studying the parameters of contraction of blood clots, formed in vitro, in blood of 41 patients with acute venous thromboses as compared with the same parameters in apparently healthy donors.
