摘要
目的探讨颅内后循环动脉瘤的临床特征、显微外科治疗的方法及其效果。方法对2000年1月至2008年10月手术治疗的10例颅内后循环动脉瘤的临床资料进行回顾分析。结果动脉瘤位于基底动脉分叉部4例，大脑后动脉P1—P2交界处2例，小脑后下动脉3例，小脑前下动脉1例。以蛛网膜下腔出血为临床表现者8例，以脑神经麻痹等占位效应为表现者2例；8例行单纯动脉瘤夹闭术，2例行动脉瘤夹闭及残颈包裹术。术后随访6个月至8年，恢复良好6例，中度伤残2例，重度残疾1例，死亡1例。结论后循环动脉瘤手术较为困难，应选择合适的入路，充分显露动脉瘤和载瘤动脉，术中尽可能保护脑干、脑干穿支动脉及脑神经，以减少手术后致死致残率。
Objective To assess the clinical characteristics and surgical treatment of intracranial posterior circulation aneurysms. Methods We reviewed 10 consecutive patients who had intracranial posterior circulation aneurysms in our hospital between 2000. 1 -2008. 10. Results The aneurysms located at basilar apex in 4 patients, at posterior cerebral artery（PCA） in 2 patients, at posterior inferior cerebellar artery（PICA） in 3 patients and at anterior cerebellar artery （AICA） in 1 patient. The aneurysms were directly clipped in 8 patients, clipped and trapped in 2 patients. Clinical outcome was evaluated with Glasgow outcome scale （GOS） scores. After 6 months - 8 years follow up, good recovery （ GOS scores of 5 ） were achieved in 6 cases , moderate disability （ GOS scores 4 ） in 2 cases, severe disability（ GOS scores 3 ） in 1 case and death （GOS scores 1 ） in 1 patient. Conclusions Compared with anterior circulation aneurysms, the surgery of posterior circulation aneurysms is more difficult and has higher surgical risks. To expose aneurysm and its parent artery, a proper surgical approach should be taken. During the operation, we should do our best protect brain stem, perforating arteries of brain stem and cranial nerves.
