Rupture of an intracranial arteriovenous malformation (AVM) in pregnancy: case report

The rupture of an intracranial arteriovenous malformation (AVM) in pregnancy is a rare occurrence, but may have fatal consequences. A link between AVM rupture and pregnancy has been proposed; it may be caused by the increased cardiac output or circulatory effects of the elevated estrogen levels. Here, we report the case of a 27-week-pregnant woman who presented with a symptomatic ruptured cerebral AVM, treated by cesarean section followed surgical resection. We achieved good maternal and fetal outcomes in our case. Surgical intervention for ruptured AVM during pregnancy could prevent re-bleeding, and allow for determination of the delivery method based on the obstetrical indications. Cooperation between neurosurgeons, obstetricians, and anesthesiologists and sufficient information about the treatment strategy given to the patients are essential.
