[Experience in thrombosis prevention and treatment in operative medicine].

Thromboembolic diseases are frequent sequelae of surgical interventions. On account of the possible severe effects an aimed prophylaxis of thrombosis in operative medicine is necessary. The classical anticoagulants may be used in surgery, if the adequate possibilities of control are present. The use of heparin in low dosage reduces the expenditure of control. Experiences with an own variant of the heparin treatment are reported in which heparin is applied intravenously. The use of tetracyclines as well as the control of the factor XIII level and, if necessary, substitution of the factor XIII are recommended. When thrombosis in the venous system appeared the conservative methods in comparison to operative thrombectomy are preferred.
