Severe thrombotic microangiopathy accompanied by liver rupture and multiorgan failure at week 26 of pregnancy.

Objective: Case of a primigravid woman who suffered from severe PTMS (postpartum thrombotic microangiopathy syndrome) in the 26th week of pregnancy.
Design: Case report.
Setting: Department of Gynecology and Obstetrics, Hospital Nový Jičín; Department of Gynecology and Obstetrics, University Hospital Ostrava; Department of Hematooncology, University Hospital Ostrava; Department of Anaesthesiology and Resuscitation, University Hospital Ostrava.
Results: A thirty-one-year old primigravid woman was admitted to a secondary level institution due to epigastric pain and spontaneous rupture of membranes at 26th week of pregnancy. On admission her blood pressure was 140/90 mm Hg and an intrauterine fetal death was confirmed. The patients condition deteriorated quickly, resulting in a hypertensive crisis (220/120 mm Hg), which did not respond to medication over a two hour period. Emergency caesarean section was performed, but the patients condition progressed to HELLP syndrome class I, DIC and MOF. She was transferred to the intensive care unit (ICU) of the district referral hospital 38 hours postpartum. On admission to ICU, liver rupture was diagnosed which was managed conservatively. Therapeutic plasma exchange (TPEX) was initiated on day 2 postpartum in response to falling platelets and continued for 6 days. Due to acute kidney injury (AKI), the patient required dialysis for 21 days. The patients condition improved gradually and at 28 days after admission to ICU she was transferred back to the referring hospital. The consensus reached by the treating teams was that PTMS was the most likely diagnosis.
Conclusion: This case demonstrates that PTMS improves (usually rapidly) after TPEX is initiated. It also emphasises the importance of maintaining a high index of suspicion for PTMS so that life-saving TPEX can be initiated, because it does not respond to classical treat-ment used in the management of HELLP syndrome. Other research suggests patients may also require a terminal complement blockade with the anti-C5 monoclonal antibody (eculizumab). Further research could focus on diagnostic tests to distinguish PTMS from HELLP to identify which patients would most benefit from these treatments.
