A 56-year-old man with ruptured right P_2-P_3 junction aneurysm and a 66-year-old man with ruptured left P_2-P_3 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 P_2 segment can be easily reached. The present approach is very useful for the treatment of ruptured aneurysms at the P_2-P_3 junction, in particular for acute stage surgery associated with packed intraventricular hemorrhage.
