[Radioiodine-fibrinogen test in the early diagnosis of venous thrombosis in the leg (author's transl)].

As long as there is no satisfactory prophylaxis for thrombosis, the radioiodine-fibrinogen test is a good supplement for the supervision of patients with a "high thrombosis risk" since the clinical symptomatology is not specific enough and phlebography cannot be used to extensively. The risk of hepatitis can be reduced when the selection of spenders is large enough. As a radionuclide, 125iodine does not appear to be any less effective than 131iodine. The postoperative injection is preferred to the preoperative injection.
