Abstract:
Objective In order to investigate the feasibility of surgical clipping of all bilateral supratentorial aneurysms via a unilateral approach. Methods Fontotemporal Craniotomies were performed on 20 cadavers to study the contralateral exposure for five common aneurysm sites in the anterior circulation such as the ophthalmic artery (OA) segment,the posterior communicating artery (PCOA) segment,theinternal carotid artery (ICA) terminal segment,the anterior communicating artery (ACOA) segment,as well as the middle cerebral artery (MCA) bifurcation. Results The contralateral OA segment was successfully exposed in 65% of specimens,the PCOA segment in 50%,the ICA terminai segment in 100%,the ACOA segment in 100% and the MCA bifurcation in 65%. Conclusion In this study,we select seriously surgical signs,it is very feasible and effective for neurosurgeon to clip successively all aneurysms of bilateral supratentorial via a approach.
