新生儿颅内出血的CT诊断

Newborn CT diagnosis of intracranial hemorrhage

目的提高对新生儿颅内出血的CT表现的认识和诊断水平。方法对70例颅内出血的CT表现作回顾性分析、研究。结果蛛网膜下腔出血56例,占80%;脑实质内出血4例,占5·7%;脑室出血3例,硬膜下血肿2例,占2·8%。①蛛网膜下腔出血是最常见类型,多合并缺氧缺血性脑病,生产过程多有轻至中度窒息史;②脑内出血多合并重度窒息史;③脑室内出血多在脑室后角形成血-脑脊液平面;④硬膜下血肿合并皮下血肿,并有产伤史。结论新生儿颅内出血的CT表现具有一定的特征性,常规的颅脑CT检查有利于颅内出血的早期发现与诊断,对临床治疗及推测愈后有一定的价值。

Objective Raise the newborn intracranial hemorrhage awareness and performance of the CT diagnosis. Methods 70 cases of intracranial hemorrhage on CT findings of a retrospective analysis and research. Results 56 cases of subarachnoid hemorrhage,accounting for 80% ;4 cases of cerebral hemorrhage,accounting for 5.7% ; intraventricular hemorrhage 3 cases,accounting for 4.3% ;2 cases of subdural hemorrhage, accounting for 2.8%. Conclusion：（1）Subarachnoid hemorrhage is the most common type,and more merger hypoxic-ischemic encephalopathy,Most of the production process with mild to moderate asphyxia history. （2）cerebral hemorrhage more with severe asphyxia history. （3）Intraventricular hemorrhage more ventricle horn formation of blood-cerebrospinal fluid plane. （4）Subdural hematoma merger subcutaneous hematoma, and the history of birth injuries. Conclusion Intracranial hemorrhage in newborns with CT findings of a certain characteristic, conventional brain CT scan to intracranial hemorrhage early detection and diagnosis,clinical treatment and more speculation after a certain value.
