摘要
目的探讨新生儿蛛网膜下腔出血的CT影像特征及其临床意义。方法回顾分析79例临床证实、CT资料齐全的新生儿蛛网膜下腔出血患儿的CT特征,所有患儿均在初治疑诊后3～48h内经常规CT扫描。结果 CT扫描证实,79例中镰刀征15例(19.0%),三角征28例(35.4%),表现为侧裂池、前后纵裂池高密度影17例(21.5%),小脑幕增宽19例(24.1%)。结论新生儿蛛网膜下腔出血CT表现具有特征性,有助于判定病情严重程度,预测患儿预后,以及指导临床治疗。
Objective To evaluate the CT findings of neonatal subarachnoid hemorrhage and their clinical significance. Methods Seventy-nine newborns with clinically proved subarachnoid hemorrhage（SAH） underwent conventional CT scans within 3-48h after initially suspicious diagnosis and then CT findings in all the newborns were analyzed retrospectively. Results Among 79 newborns with SAH,sickle sign was found in 15（19.0%） cases,triangular sign in 28（35.4%） cases,hyperdense shadows of sylvian cistern and longitudinal cistern in 17（21.5%） cases,and widening of cerebellar tentorium in 19（24.1%） cases. Conclusion The CT findings of neonatal SAH have certain characteristics which are helpful to identify the severity of pathologic changes,to predict the prognosis of ill newborns,and to guide the clinical treatment.
