Intracranial haemorrhage in pregnancy

Jacob M Fairhall et al. Obstet Med. 2009 Dec.

Abstract

Intracranial haemorrhage (ICH) is a rare, yet potentially devastating event in pregnancy. There is a risk of maternal mortality or morbidity and a significant risk to the unborn child. The risk of haemorrhage increases during the third trimester and is greatest during parturition and the puerperium. ICH can be extradural, subdural, subarachnoid or intraparenchymal. Causes of bleeding include trauma, arteriovenous malformations, aneurysms, preeclampsia/eclampsia and venous thrombosis. Urgent neurosurgical conditions generally outweigh obstetric considerations in management decisions, although anaesthetic and surgical modifications can be made to minimize adverse effects to the fetus.

Keywords: arteriovenous malformations; cerebral aneurysms; intracerebral haemorrhage; pregnancy; stroke; subarachnoid haemorrhage.

Non-contrast computed tomography demonstrating left putaminal haemorrhage (arrow). This 35-year-old patient was being treated for depression with a monoamine oxidase inhibitor (MAOI) during pregnancy. After delivery, she ate a large amount of cheese and had an MAOI hypertensive crisis. She had a depressed conscious state on admission and was treated with craniotomy and evacuation of the haematoma. She made a full neurological recovery
