Thrombotische Mikroangiopathien in der operativen Intensivmedizin unter besonderer Berücksichtigung des atypischen hämolytisch-urämischen Syndroms

Thrombotic microangiopathies (TMA) are rare diseases, which are defined by the triad microangiopathic hemolytic anemia, thrombocytopenia and organ damage, and are associated with high morbidity and mortality. The recognition of a TMA and the distinction of important differential diagnoses are key factors, particularly in a perioperative context and in routine clinical intensive care. The further differentiation of the different TMA subtypes, such as thrombotic thrombocytopenic purpura (TTP), Shiga toxin-producing Escherichia coli hemolytic uremic syndrome (STEC-HUS) and atypical hemolytic uremic syndrome (aHUS), based on the underlying pathophysiology and the development of new targeted treatment options in recent years have significantly improved the prognosis. A close interdisciplinary cooperation between critical care specialists and specialist disciplines experienced in the treatment of TMA, is essential for a prompt diagnosis and the initiation of the appropriate treatment.
