目的：提高对新生儿颅内出血CT表现的认识和诊断水平。材料与方法：对经临床确诊的94例新生儿缺氧缺血性脑损伤中69例颅内出血的CT表现进行回顾性分析研究。结果：颅内出血阳性率为73．4％。蛛网膜下腔出血42例，脑室内出血4例，脑实质出血3例，硬膜下出血2例，室管膜下出血1例，混合性出血17例。其中蛛网膜下胜出血最常见，占60％，沿纵裂的条线状高密度影或直窦、塞汇及天幕缘出现的“Y”或“V”型特殊高密度是蛛网膜下腔出血的特征性表现。结论：新生儿颅内出血的CT表现具有一定的特征性，常规颅脑CT检查有利于颅内出血的早期发现与诊断，对临床治疗及推测预后有一定价值。
Objective: To improve the understanding and diagnosis of neonatal intracranial hemorrhage CT findings. Materials and Methods: The clinical manifestations of 69 cases of intracranial hemorrhage in 94 neonates with hypoxic-ischemic brain damage were retrospectively analyzed. Results: The positive rate of intracranial hemorrhage was 73.4%. 42 cases of subarachnoid hemorrhage, 4 cases of intraventricular hemorrhage, 3 cases of cerebral parenchymal hemorrhage, 2 cases of subdural hemorrhage, 1 case of subependymal hemorrhage, and 17 cases of mixed hemorrhage. One of the most common subarachnoid hemorrhage, accounting for 60%, along the longitudinal line of linear high-density shadow or straight sinus, the Department of convergence and the sky edge of the emergence of “Y” or “V” type of special high-density subarachnoid space The characteristic manifestations of bleeding. Conclusion: The CT findings of intracranial hemorrhage in neonates have certain characteristics. Conventional craniocerebral CT examination is helpful for the early detection and diagnosis of intracranial hemorrhage, which has some value for clinical treatment and prognosis.
