[Tonsillectomy in patients with bleeding disorders].

When injury of a major vessel can be ruled out as the cause of bleeding after tonsillectomy, a discrete disturbance of hemostasis must be considered. These are mainly slight thrombopathies or a pathologically increased fibrinolysis, which were not detected by routine tests and the past history. In former times severe bleeding disorders were a strict contra-indication for tonsillectomy. Under the supposition of an exact coagulogram and the substitution of highly purified factor concentrates the risk of severe post-tonsillectomy hemorrhages in such patients today is nearly the same as in patients with a normal hemostase.
