Management of Ruptured Right Basal Ganglion Arteriovenous Malformation in a Pregnant Woman: A Case Report
Year: 2026
Type: article
Study design: Case Report
Abstract: Aim and background: Brain arteriovenous malformations (BAVMs) are rare congenital vascular anomalies characterized by direct arteriovenous communications without an intervening capillary network.Although they often remain clinically silent, their rupture during pregnancy can lead to devastating intracranial hemorrhage with significant maternal and fetal morbidity and mortality.The physiological alterations of pregnancy, including increased blood volume and hormonal influences, may further predispose to rupture.The present study aims to assess maternal and fetal outcomes in cases of ruptured BAVMs during pregnancy and to discuss appropriate diagnostic and therapeutic strategies for effective management of this critical condition.Case description: A 29-year-old unregistered antenatal woman, at 7 months of amenorrhea, presented with giddiness, a fall, vomiting, headache, and transient loss of consciousness.Computed tomography (CT) imaging revealed a right ganglio-capsular bleed with intraventricular extension.Magnetic resonance imaging (MRI) and angiography identified a ruptured right parietal arteriovenous malformation (AVM), confirmed by digital subtraction angiography (DSA).The lesion was successfully completely embolized on 20/12/2024 by interventional radiologists, followed by multidisciplinary management involving neurosurgery and obstetrics.Considering maternal stability and fetal viability, an elective lower segment cesarean section (LSCS) was performed at 34 weeks, delivering a healthy 2 kg male baby.Both mother and baby recovered uneventfully and were discharged in stable condition on post-operative day (POD) 8. Conclusion: This report describes a rare case of ruptured BAVM in pregnancy and emphasizes the importance of early diagnosis, multidisciplinary care, and individualized delivery planning.Clinical significance: This case underscores the importance of early diagnosis and close collaboration between neurosurgery, obstetrics, and radiology teams to minimize morbidity and mortality in pregnant women with ruptured AVMs.
