[Spectrum of von Willebrand-Jürgens syndrome. A study on 53 patients].

Von Willebrand-Jürgens syndrome was diagnosed in 53 patients on the basis of bleeding symptoms and blood clotting analytical findings. It was possible to classify the patients into four types using the recommendations of the European Thrombosis Research Organization. Type I, 56%, was most common, 15% belonged to type II, 13% to type III and 16% to type IV. Whereas type I corresponds to the so-called classical von Willebrand-Jürgens syndrome, types II-IV demonstrate the heterogeneity of the disease.
