Six infants with cerebral infarcts were examined prospectively with real-time sonography to determine the sonographic characteristics of infarcts and their evolution. Patients' ages ranged from 1 day to 7 months, and serial sonographic and/or CT scans were obtained over a period of 2 weeks to 14 months in the survivors. Among our patients the most characteristic sonographic findings of infarction were absence of gyral definition, absence of vascular pulsations, altered parenchymal echogenicity, and territorial distribution. Mass effect, reflected in ventricular size and shift of midline structures, may also be seen and largely parallels the extent of the infarction. Evolution of infarcts was seen sonographically as gradual return of arterial pulsations and concurrent development of cystic spaces. Sonography was found to be a valuable tool in the diagnosis of infarction in infancy and in monitoring its evolution, although CT was necessary for adequate initial evaluation in older infants.
对6例患有脑梗死的婴儿进行了实时超声检查，以确定梗死灶的超声特征及其演变过程。患者年龄从1天至7个月不等，存活者在2周至14个月的时间内接受了系列超声和/或CT扫描。在我们的患者中，梗死最具特征性的超声表现为脑回形态消失、血管搏动消失、实质回声改变以及区域分布。脑室大小和中线结构移位所反映的占位效应也可能出现，且在很大程度上与梗死范围平行。梗死灶的演变在超声上表现为动脉搏动逐渐恢复以及同时出现囊腔形成。超声检查被发现是诊断婴儿期梗死及监测其演变的有价值工具，不过对于较大婴儿的充分初始评估，CT是必要的。
