Dengue haemorrhagic fever (DHF) is a common tropical disease. An increasing frequency of dengue fever and DHF in pregnancy is being observed, with a rising incidence among adults. This case report describes the management of a woman in her early 30s, gravida 3, para 2, at 34 weeks of gestation, presenting with DHF and dengue shock syndrome, with a history of two previous caesarean sections. The patient developed severe complications, including preterm labour, atonic postpartum haemorrhage and significant haematoma formation, requiring complex multidisciplinary care. Despite these challenges, both maternal and fetal outcomes were successfully managed through vigilant monitoring and timely interventions.
