Abstract
A 34-year-old primigravida at 9 weeks of gestation presented with sudden headache and consciousness disturbance. Computed tomography (CT), CT angiography (CTA), and angiography showed subarachnoid hemorrhage and a large ruptured aneurysm of the left internal carotid artery. She was immediately admitted and underwent bilateral ventricular drainage, and her consciousness improved slightly. Endovascular embolization of the aneurysm was then performed, resulting in almost complete occlusion of the aneurysmal sac. The patient recovered fully, and a healthy baby was delivered at the 38th week of gestation via cesarean section. Though this case had a good outcome, management of ruptured cerebral aneurysms during early pregnancy requires more discussion.
