Abstract:
Intracranial hemorrhage due to arteriovenous malformation or intracranial aneurysms is a rare but grave complication of pregnancy. We analyse 15 cases. Among these, aneurysms ruptures were responsible for the bleeding in 5 instances. Arteriovenous malformation was diagnosed in other 6 patients. The maternal and fetal mortality was 20% and 33% respectively. Four aneurysm patients were operated on before delivery. We conclude that surgical management of the aneurysms is associated with lower maternal and fetal mortality than the conservative treatment. The management of angiomatous hemorrhage during pregnancy remains controversial.
