BACKGROUND: Pulmonary embolism (PE) is a common cause of maternal death during pregnancy and the puerperium yet data on its prevalence in middle-income countries is lacking.
METHODS: We examined the medical records and CTPA (computed tomography pulmonary angiography) images of 67 women in an obstetric high care unit during pregnancy and the puerperium. We aimed to determine the prevalence of PE in a high-risk obstetric population undergoing CTPA, assess associated clinical features in this cohort, and determine the prevalence of alternative CT findings.
RESULTS: CTPA detected PE in 11 women (16.42%) and alternative CT findings in 46 (68.6%). Women with PE had a lower systolic blood pressure than those without PE (P = 0.001). Multiple gestation, preterm rupture of membranes, and gestational diabetes were linked to higher PE prevalence.
CONCLUSIONS: This study, set in an upper middle-income country, demonstrated a higher CTPA yield for PE and alternative diagnoses than in international literature, emphasising context-specific assessments.
