目的 :研究高海拔地区新生儿缺氧缺血性脑病 (HIE)的CT表现并进行分析 ,以提高CT早期诊断价值 ,达到对该病的早期及时治疗和预后恢复的观察。方法 :对西宁地区 (海拔 2 2 6 0m )2 98例临床有缺氧缺血性脑病症状的新生儿患者进行头颅CT扫描检查并对其CT表现进行分析。结果 :高海拔地区HIE头颅CT表现为脑水肿和颅内出血 ,脑水肿可分为轻度、中度、重度三型 ,颅内出血可见到蛛网膜下腔出血、脑室出血、脑实质出血。结论 :高海拔地区HIE发病率明显偏高 ,早期行头颅CT扫描检查对高海拔地区HIE早期诊断、分型、预后的判断、治疗起着重要决定作用
Objective: To study the CT findings of neonatal hypoxic-ischemic encephalopathy (HIE) in high altitude areas and to analyze the results in order to improve the value of early diagnosis of CT and achieve the early timely treatment and prognosis recovery of the disease. Methods: A total of 2 98 neonatal neonates with clinical symptoms of hypoxic-ischemic encephalopathy in Xining area (2260 m above sea level) were examined by CT scans and their CT findings were analyzed. Results: HIE head CT in high altitude showed cerebral edema and intracranial hemorrhage. Cerebral edema was divided into mild, moderate and severe type III. Subarachnoid hemorrhage, ventricular hemorrhage and intraparenchymal hemorrhage were found in intracranial hemorrhage. Conclusions: The incidence of HIE in high altitude area is obviously high. Early CT scan examination plays an important role in the early diagnosis, classification and prognosis of HIE in high altitude areas.
