254 consecutive cases of angiographically demonstrated intracranial cerebral aneurysms occurring over a three year period were reviewed with specific reference to aneurysm multiplicity, site, patient age and the presence of infundibular abnormalities. The overall incidence of multiple aneurysms was 44.9%. Female patients accounted for 66.5% of all aneurysm cases. The incidence of multiplicity was higher in women (51.5%) than men (31.7%) and overall was higher in patients over 40 years of age (52.8%) compared to those under this age (26.3%). Infundibula occurred in 27.2% of all patients and 9.45% of all patients demonstrated infundibular dilatation of the origin of the posterior communicating artery.
回顾了在三年期间血管造影显示的254例颅内脑动脉瘤连续病例，特别参考了动脉瘤的多发性、部位、患者年龄以及漏斗状异常的存在情况。多发性动脉瘤的总体发生率为44.9%。女性患者占所有动脉瘤病例的66.5%。女性多发性动脉瘤的发生率（51.5%）高于男性（31.7%），总体而言，40岁以上患者（52.8%）的发生率高于该年龄以下患者（26.3%）。27.2%的患者出现漏斗状结构，9.45%的患者显示后交通动脉起始处漏斗状扩张。
