目的 使用三维CT重建技术对健 康成年人群的侧脑室额角穿刺冠状平面的 侧脑室宽度的正常值范围进行测量，研究 进行侧脑室额角穿刺的最适宜方向。 方 法 选择2013年1月-2016年1月来我院进 行体检的正常健康成年人共68例，收集 体检者的原始颅脑CT数据。使用三维CT 重建技术对体检者的侧脑室额角穿刺冠 状平面进行重建，在该平面上对单侧侧 脑室宽度进行测量。将中线旁开2.5cm处 作为为标准穿刺点，然后进行侧脑室额 角穿刺的模拟。结果 68例健康成年人的 单侧侧脑室的平均宽度为(15.59±2.85) mm(95%置信区间：15.32-16.26mm)。其 中：年龄＜44岁组侧脑室平均宽度为 (13.49±3.32)mm；45＜年龄＜59岁组平 均宽度为(15.24±3.65)mm；60＜年龄 ＜74岁组平均宽度为(15.96±3.57)mm， 年龄＞75岁组平均宽度为(18.63±2.96) mm，分析后发现差异有统计学意义 (P<0.05)。所有体检者的平均最大偏开角 度为(17.66±1.53)，通过统计学分析发 现不同年龄组的最大偏开角度差异无统计 学意义(P>0.05)；平均最小偏开角度为 (6.08±3.27)，且各组差异有统计学意义 (P＜0.05)。结论 健康成年人群的侧脑室 宽度会随年龄的增长而增大，而偏开角度 会随年龄的增长而减小，通过研究发现侧 脑室额角穿刺的最适宜偏开角度范围为 6.08～17.66之间，能够保障穿刺的成功 率。

Objective 3D CT reconstruction technique was used to explore healthy adults lateral ventricle puncture of frontal horn of coronal plane of the width of the lateral ventricles of normal value range, to explore the most appropriate direction of frontal horn of lateral ventricle puncture. Methods The data of 68 cases of normal healthy adults in our hospital from January 2013 to January 2016 were collected, and the brain CT data of physical examination were collected. The groups were divided according to the age: age<44 group, (2)45<age<59 group,="" (3)60<age<74="" age="">75 group. 3D CT reconstruction technique was used on physical examination of frontal horn of lateral ventricle puncture in the coronal plane were reconstructed, ventricle width were measured in the plane of unilateral. 2.5 cm next to middle lane was used as standard puncture point, and then simulate the frontal horn of lateral ventricle puncture. Results The average width of the lateral ventricles in 68 healthy adults was (15.59+2.85)mm (95% confidence interval: 15.32 to 16.26mm). Age < 44 group of lateral ventricle width was (13.49 3.32mm), the average width of 45 < age < 59 group was(15.24+3.65)mm, average width of 60 < age < 74 group was (15.96+3.57mm), and the average width of age>75 group was (18.63+2.96)mm, the difference was statistically significant (P<0.05). All persons of average maximum partial open angle was (17.66+1.53), the statistical analysis found that the largest partial open angle was not statistically significant different in all age group (P>0.05), average minimum deviation angle was (60.8+3.27), and there were significant differences between the groups (P<0.05). Conclusion The width of the lateral ventricles healthy adult population will increases with the growth of the age, and partial angle will decrease with the growth of the age, the research found that the most suitable partial angle range of frontal horn of lateral ventricle puncture is between 6.08 to 17.66, can safeguard the success rate of the puncture.
