Inclusion |
Intracranial saccular sidewall aneurysm as treatment target |

No previous treatment or any previous treatment directed at the aneurysm sac without complete occlusion of the aneurysm from circulation |
No previous treatment to the parent vessel |
An ability and willingness of the patient to take the necessary medication for midterm dual platelet function inhibition |
Exclusion |
Bifurcation-type aneurysm or fusiform vessel dilation as a treatment target |
Implants other than p64 used |
Aneurysm rupture ≤30 days prior to the p64 treatment |
Extradural asymptomatic aneurysm |
Anticipated ease or sufficiency of clip or coil treatment |
Previous implantation of stents or flow diverters to the target-vessel segment |
