Objectives: To investigate the epidemiologic and clinical characteristics of maternal near-misses attributable to haemorrhagic stroke (HS) occurring in patients with hypertensive disorders of pregnancy (HDP), with a focus on severe neurological morbidity.

Methods: A national retrospective cohort study was conducted using the national database of health insurance claims for the period 2010 to 2017. The subjects were all insured women with a diagnosis of both HDP and HS. Severe neurological morbidity requiring rehabilitation, types of HDP, types of HS, and magnesium sulphate use were tabulated.

Results: The number of women with HDP who were diagnosed with HS was 3.4 per 100,000 deliveries between 2010 and 2017. Forty percent of HDP-related HS cases had neurological morbidities requiring rehabilitation (1.4 per 100,000 deliveries), and 4.4% were in a persistent vegetative state after HS. Of the HDP cases who developed HS, 69.2% were severe HDP, of which 55.6% were without eclampsia. The most common type of HS was intracerebral haemorrhage (2.5 per 100,000 deliveries), followed by subarachnoid haemorrhage due to cerebral aneurysm (1.2 per 100,000 deliveries). The frequency of magnesium sulphate use increased in all patients with HDP-related HS in the second half of the study period (2014-2017) compared with the first half (2010-2013) (p < 0.0001). This was more evident in cases of HDP-related HS with eclampsia (31.9% to 83.8%) compared to those without eclampsia (25.0% to 42.9%).

Conclusion: Of the maternal near-miss cases due to HDP-related HS, 40.0% were rehabilitated and 69.2% were HDP without either eclampsia or severe hypertension.
