This review of 611 cases of aneurysms in the posterior fossa managed by one neurosurgeon between 1965 and 1980 shows that eye signs are important indications for investigation and may lead to earlier detection and treatment of the aneurysm. They were present in 50% of the patients. Major defects in ocular motility or the visual field were present preoperatively in 57 of the 64 patients with unfavourable surgical results--postoperative death or total physical dependency. Of the same 64 patients 55% (35) had "giant" aneurysms, as compared with 17% (102) of the entire group of patients. Hypertension was present in 50% of the patients who died and 25% of those with poor functional results after surgery. Computer-assisted tomography and four-vessel angiography are essential for accurate localization of the aneurysm and for blood-flow information important in determining the best surgical approach.
本文回顾了一位神经外科医生在1965年至1980年间处理的611例后颅窝动脉瘤病例，结果显示眼部体征是进行检查的重要指征，可能有助于更早地发现和治疗动脉瘤。50%的患者出现了眼部体征。在64例手术结果不佳（术后死亡或完全丧失生活自理能力）的患者中，有57例在术前存在眼球运动或视野的严重缺陷。在这64例患者中，55%（35例）患有“巨大”动脉瘤，而在整个患者群体中这一比例为17%（102例）。50%的死亡患者和25%术后功能恢复不佳的患者患有高血压。计算机断层扫描和四血管造影对于准确确定动脉瘤的位置以及获取对确定最佳手术方法至关重要的血流信息必不可少。
