Introduction: Diagnosis of postpartum thrombotic microangiopathies in pregnancy is a challenge, but plasma exchange (PE) is life-saving in such cases. This study was conducted with the aim to find the result of the early start of PE in such patients. Materials and Methods: There were a total of seven clinically diagnosed cases of post partum thrombotic microangiopathies (PP-TMA) where PE was done. The diagnosis of PP-HUS and decision to start PE in such cases were based on the classical triad of microangiopathic hemolytic anemia, thrombocytopenia, and acute renal failure. All the PE procedures were done using fully automatic COM.TEC (Fresenius Kabi, Germany). Results: Immediately before the start of PE, the mean platelet count and serum lactate dehydrogenase (LDH) and hemoglobin (Hb) were 53.1 × 109/L, 10,943 IU/L, and 6.4 gm%, respectively. After seven sessions of PE, platelet count improved to 158 × 109/L and LDH dropped to 609 IU/L, and Hb improved to 10.3 gm% (P < 0.05). We got a positive renal response in four patients in whom serum creatinine value reached within normal range while in the remaining three patients, no positive renal response was obtained and serum creatinine remained above normal range. Thus, the response of PE was shown to be inadequate in three patients. Compliance to PE was good. Patients were discharged after 20 days (mean) of hospital admission. Conclusion: PE is life-saving in PP-HUS. High degree of clinical suspicion to it and early start of PE were crucial for successful outcome in our patient population.
