Abstract
Surgical approaches to multiple intracranial aneurysms were reported.
1) Aneurysms of the unilateral circle of Willis' plus ipsilateral MC aneurysm-through frontotemporal craniotomy, pterional approach.
2) 1) plus distal AC aneurysm-through anteriorly extended frontotemporal approach. The distal AC aneurysm approached interhemispherically.
3) 1) plus ipsilateral distal PC aneurysm-through posteriorly extended frontotemporal approach. The distal PC aneurysm approached subtemporally.
4) 1) plus contralateral IC and/or MC aneurysm-approximately 1/2 of IC and 1/3 of MC contralateral aneurysms could be clipped successfully through unilateral pterional approach.
