Abstract
Thrombotic thrombocytopenic purpura (TTP) is a rare, life-threatening disorder, which is characterized by thrombus formation in small blood vessels. The present study retrospectively analyzed the clinical data from two patients with severe TTP, who were treated successfully in the intensive care unit (ICU) at the Liaocheng People's Hospital in 2013. Comprehensive therapies were administered to the patients, including plasma exchange (PE), mechanical ventilation (case 1 only), steroid therapy, blood transfusion and anti-inflammatory treatment (case 2 only). The two patients returned to a stable state and were transferred back to the hematology department following PE. The positive outcome achieved for these patients suggests that early intervention involving bedside PE in the ICU may reduce the mortality rate of patients with severe TTP who have concurrent respiratory or circulatory failure and cannot be treated in the dialysis unit.
