【摘要】 目的：研究新生儿蛛网膜下腔出血的ＣＴ表现，提示新征象。材料和方法：对１１０例新生儿蛛网膜下腔出血（ＳＡＨ）的ＣＴ平扫资料，分析不同的出血和积血部位形成的不同ＣＴ图像特征。并与６０例成人ＳＡＨ的ＣＴ表现加以对照。结果：发现三个特殊ＣＴ征象：（１）矢状窦旁征（Δ征）８７例（７９．０％）－血液积聚于矢状窦及窦汇旁。（２）天幕缘征（Ｙ征）５５例（５０．０％）－血液积聚于小脑天幕缘上下。（３）边缘模糊征９１例（８２．７％）－血液积聚于纵裂池内，深入至大脑半球内侧面脑沟内。结论：蛛网膜下腔出血由于出血部位不同可形成不同的ＣＴ表现。作者提出三个新征象：矢状窦旁征，天幕缘征，边缘模糊征。对新生儿蛛网膜下腔出血的诊断有重要价值。更多还原

【Abstract】 Purpose: A study of CT manifestation of SAH(Subarachoid Space Hemorrhage) in new born was undertaken with new signs suggested. Materials and Methods: The plain CT scans of 110 cases of SAH in new born were analysed resulting in different CT image charateristic due to various kinds and positions of the hemorrhage. Furthermore a comparision with those of the 60 adult SAH cases was also included. Results: The discovery of 3 specific CT findings. (1) parasagittal sinus sign (△Sign) 87 cases (79.0%)-blood accumulated in sagittal sinus and parasinusoid space. (2) tenting border sign (Y Sign), 55 cases (50.0%)-blood accumulated along the superier and inferior parts of the cerebellar tenting border. (3) border blurring sign, 91 cases (80.7%)-blood accumulation within the longitudinal fissure cietern deepering into the internal sulci of the cerebral hemispheres.Conclusion: There were different kinds of CT manifestations of SAH according to the sites of the hemorrhages. The authors presented 3 new specific signs. parasagittal sinus sign, tenting border sign and border blurring sign. All of them posscessed the important value in diagnosing SAH of the new born.更多还原
