[Spontaneous subarachnoid hemorrhage in pregnancy].

Subarachnoid haemorrhage from an intracranial aneurysm or arteriovenous malformation is a grave complication of pregnancy. The authors analyzed 11 cases of verified subarachnoid haemorrhage during pregnancy from 10 identified and 1 unidentified cerebral vascular malformation. The aneurysms were responsible for subarachnoid haemorrhage in 6, and arteriovenous malformation in 4 patients. We conclude that the decision to operate after subarachnoid haemorrhage during pregnancy should be based upon neurosurgical principles, whereas cesarean delivery should be done in every pregnant patient with subarachnoid haemorrhage.
