Doppler-sonography of the intracranial arteries in the sagittal section through the open anterior fontanelle may yield valuable information on the cerebral blood-flow in infants. Applying the directional method, the anterior-cerebral artery could be recorded in all probands; by using the pulsed technique at least one artery was identified in 95% of the cases. There was a significant difference in pulsation-index (P.I.) between the pulsed and the directional method. Both methods revealed a reduction of the P.I. in infants with brain edema, and an increase of the P.I. after intracranial haemorrhage had occurred. The P.I. was significantly increased in infants younger than 36 gestational weeks, compared with healthy term newborns older than 40 weeks. The clinical relevance for diagnostic purposes as well as for therapeutic monitoring is discussed.
通过开放的前囟门矢状切面进行颅内动脉的多普勒超声检查，可为婴儿脑血流提供有价值的信息。采用定向法，所有受试对象均能记录到大脑前动脉；使用脉冲技术时，95%的病例至少能识别出一条动脉。脉冲法和定向法的搏动指数（P.I.）存在显著差异。两种方法均显示，脑水肿婴儿的P.I.降低，颅内出血后P.I.升高。与孕周大于40周的健康足月儿相比，孕周小于36周的婴儿P.I.显著升高。本文讨论了其在诊断及治疗监测方面的临床意义。
