蛛网膜下腔出血CT分布对颅内动脉瘤检出的价值
目的 通过对比分析不同部位动脉瘤致蛛网膜下腔出血(SAH)的分布差异,探讨其CT分布对提高CTA颅内动脉瘤检出率的价值.方法 对2019年1月至2020年10月首都医科大学附属北京天坛医院收治的415例颅内动脉瘤致SAH患者行CT和CTA检查,比较不同部位动脉瘤致SAH的分布差异,对比分析高年资与低年资影像科医师对动脉瘤的检出率.结果 共415例患者计463个动脉瘤,包括Ⅰ类动脉瘤324个、Ⅱ类动脉瘤139个;其中责任动脉瘤415个,包括Ⅰ类动脉瘤295个、Ⅱ类动脉瘤120个.Ⅰ类动脉瘤出血主要分布于鞍上池(95.93％,283/295)、环池(90.17％,266/295)、纵裂(86.44...

| Abstract | 目的 通过对比分析不同部位动脉瘤致蛛网膜下腔出血(SAH)的分布差异,探讨其CT分布对提高CTA颅内动脉瘤检出率的价值.方法 对2019年1月至2020年10月首都医科大学附属北京天坛医院收治的415例颅内动脉瘤致SAH患者行CT和CTA检查,比较不同部位动脉瘤致SAH的分布差异,对比分析高年资与低年资影像科医师对动脉瘤的检出率.结果 共415例患者计463个动脉瘤,包括Ⅰ类动脉瘤324个、Ⅱ类动脉瘤139个;其中责任动脉瘤415个,包括Ⅰ类动脉瘤295个、Ⅱ类动脉瘤120个.Ⅰ类动脉瘤出血主要分布于鞍上池(95.93％,283/295)、环池(90.17％,266/295)、纵裂(86.44％,255/295)、侧裂池(81.02％,239/295)、四叠体池(61.69％,182/295)和桥前池(50.85％,150/295),Ⅱ 类动脉瘤出血主要分布于侧裂池(85.83％,103/120)、纵裂(80.83％,97/120)、鞍上池(78.33％,94/120)、环池(77.50％,93/120)、桥前池(67.50％,81/120)和四叠体池(66.67％,80/120);Ⅰ类动脉瘤出血位于鞍上池[95.93％(283/295)对 78.33％(94/120);x2=31.761,P=0.001]和环池[90.17％(266/295)对 77.50％(93/120);x2=11.730,P=0.001]比例高于Ⅱ类动脉瘤,位于桥前池比例低于Ⅱ类动脉瘤[50.85％(150/295)对67.50％(81/120);x2=9.585,P=0.002).低年资医师动脉瘤总体检出率(配对x2检验:P=0.000)和Ⅱ类动脉瘤检出率(配对x2检验:P=0.000)均低于高年资医师,经培训后Ⅱ类动脉瘤检出率接近高年资医师水平(配对x2检验:P=0.146).结论 颅内动脉瘤致SAH的CT分布具有规律性,有助于提高CTA颅内动脉瘤检出率. |
