Pre-eclampsia, gestational diabetes and hypertensive disorders in patients with intracranial aneurysms: A case-control study.

Pre-eclampsia was significantly more frequent in patients with sIA than in their population controls. Irregularly shaped aneurysms were more frequent in sIA patients with pre-eclampsia. Further studies are required to determine whether history of pre-eclampsia may indicate an elevated risk for sIA formation or rupture.
