Abstract

A 56-year-old man with ruptured right P₂-P₃ junction aneurysm and a 66-year-old man with ruptured left P₂-P₃ junction aneurysm of the posterior cerebral artery associated with acute-stage packed intraventricular hemorrhage. The aneurysms were successfully clipped through the transcortical transchoroidal fissure approach. This approach requires less retraction of the temporal lobe, provides a wider surgical field, and the P₂ segment can be easily reached. The present approach is very useful for the treatment of ruptured aneurysms at the P₂-P₃ junction, in particular for acute stage surgery associated with packed intraventricular hemorrhage.
