Abstract

Objective: To describe timing, antecedent events, and outcomes in pregnancy-related stroke (PAS).

Methods: Retrospective single-center cohort of all PAS within 42 days of delivery from September 2010 to May 2021. Data were abstracted from medical records.

Results: Among 51 500 births, we identified 91 cases of PAS, with a stroke rate of 177 per 100 000 births. Of all PAS, 62% (n = 56) were hemorrhagic, 56% (n = 51) occurred postpartum, 49% (n = 45) occurred in patients with hypertensive disorders of pregnancy (HDP), and 36% (n = 33) had surgical interventions. There were nine deaths, with a case fatality rate of 9.9%. Of the survivors (n = 82), 37 (45.1%) had residual deficits. Patients with HDP were more likely to have a postpartum stroke than those without HDP (crude relative risk 1.72, 95% confidence interval 1.16-2.55). Among patients with HDP, 89% had at least one severe range blood pressure (BP), with a peak systolic BP of 187.8 ± 27.9 mm Hg and a peak diastolic BP of 109.4 ± 18.4 mm Hg. There was no difference in presenting symptoms (P = 0.120), residual deficits (P = 0.609), or mortality (P = 0.739) between those with or without HDP.

Conclusions: At a referral hospital, PAS was uncommon but was associated with a high mortality rate. An improved understanding of the modifiable risk factors is warranted to avert the sequelae of PAS.
