[Postoperative prophylaxis of thromboembolism. Present position.(author's transl)]

Only anti-coagulators and aggregation-stoppers may be said to be the medicamental prophylaxis of thromboembolism. The Cumarin-Indandion group is burdened with continuous laboratory controls. Contraindications excluding a general prophylaxis for this group as well as for Heparin and ASS exist. Infukoll, which is virtually always applicable, has the disadvantage that it has to be infused. Heparin- and Dextranspreparations however can already be used preoperatively, which means that a further decline of the coagulation complications can be expected.
