[Fragmented erythrocytes (schizocytes) after surgical interventions].

Fragmented erythrocytes (schistocytes) develop as a consequence of erythrocytes being damaged mechanically. Cardiac and vessel anomalies as well as diseases of small vessels with disturbances of the microcirculation may be considered as the main causes. Intravasal haemolysis appearing after artificial heart valve replacement is characterized by the appearance of schistocytes. In laboratory chemical respect there are signs of a haemolysis. The treatment depends on the seriousness of clinical symptoms.
