摘要
报告10例病人经颅底入路夹闭或切除颅内动脉瘤,获得优7例,良1例,中1例,差1例的满意效果.采用的颅底入路有四种:①经额眶入路处理前交通动脉瘤4例;②经眶颧入路处理眼动脉瘤4例,大脑中动脉瘤1例;③经岩骨小脑幕入路夹闭基底动脉中段动脉瘤1例;④经眶颧-颞极入路夹闭基底动脉分叉部动脉瘤1例.在选择的病人中,颅底入路可改善对深部或巨大动脉瘤的显露,因此减少对脑组织的牵拉.对手术的适应证、手术方法、颅底入路的优缺点进行简要讨论.
Cranial base approaches were adopted to expose and treat 10 patients with intracra-nial aneurysms. The results were excellent in 7 cases, good in 1 case, fair in 1 case and poor in 1 case. There were 4 types of cranial base approaches used: (1) transfronto-orbital approach for ACoA aneurysms in 3 cases; (2) transor-bitozygomatic approach for proximal ICA a neurysm in 4 cases and MCA aneurysm in 1 case; (3) transpetrosal-transtentorial approach for midbasilar artery aneurysm in 1 case; ( 4) transorbitozygomatic-temporopolar approach for basilar tip aneurysm in 1 case. Cranial base approaches, when used selectively, can improve the exposure of deep-seated aneurysms and large or giant aneurysms with minimal brain retraction. The indications and operative technique were briefly discussed.
