Ruptured distal anterior choroidal artery aneurysm

Journal of Clinical Neuroscience, 2006
Ruptured aneurysms of the distal anterior choroidal artery (AchA) are extremely rare and management is dictated by clinical presentation. This report describes a rare patient with a distal AchA aneurysm and subarachnoid and intraventricular haemorrhage. A 60-year-old woman presented with a sudden onset of severe headache and vomiting.

Transcortical transventricular transchoroidal-fissure approach to distal fusiform hyperplastic anterior choroidal artery aneurysms

, 2023
A hyperplastic anterior choroidal artery is a vascular anomaly where the anterior choroidal artery supplies the posterior cerebral artery territory. We report a case of subarachnoid hemorrhage from a hyperplastic anterior choroidal artery with tandem ...
