[Prophylaxis and therapy of shunt thrombosis in terminal renal insufficiency (author's transl)]

In terminal renal insufficiency thrombosis occurs almost exclusively in the arteriovenous shunt. The management of this acute, life threatening thrombosis is hardly contested. On the other hand, few results are available concerning effective thrombosis prophylaxis. In addition to the effectiveness, the pharmacokinetics of a substance and also possible bleeding complications must be taken into account. The parenteral administration of heparin and its short half life restrict it to use in thehospital. Oral anticoagulants, because they are difficult to dose, should be avoided when possible. Dextrans (Rheomacrodex) and acetylsalicylic acid (Colfarit) appear to be best suited for thrombosis prophylaxis in renal insufficiency. Dextran has the disadvantage of volume overload, and acetylsalicylic acid that of stomach intolerance. Sulfinpyrazone (Anturano) also appears to be effective, although its pharmacokinetic behaviour in renal insufficiency is still not known. Dipyridamole (Persantin), whose effectiveness for this purpose has not yet been demonstrate, should be administered even more cautiously.
