Ruptured brain arteriovenous malformation in a pregnant woman: a case report.

BACKGROUND

Brain arteriovenous malformations (bAVMs) are vascular lesions that commonly present with intracranial haemorrhage. Pregnancy has been associated with an increased risk of bAVM rupture. However, their natural history in pregnant women is uncertain.

CASE DESCRIPTION: A 27-year-old female at 28 weeks of gestation presented with a compromised neurological status secondary to a ruptured left frontal Spetzler-Martin scale (SM) III + bAVM. An emergent caesarean section was performed due to the high risk of foetal distress. Endovascular treatment successfully controlled the bleeding site, and stereotactic radiosurgery was offered as a subsequent treatment option.

CONCLUSION

bAVMs should be considered in pregnant women with intracranial haemorrhage. The management of these lesions during pregnancy is controversial. Surgical risk and foetal development should be considered when selecting a management strategy.
