目得：为了测试分级在多普勒超声（US）扫描，以确定和监测婴儿改变颅compliance.MATERIALS和METHODS：在多普勒超声扫描的大脑中动脉的前囟施加压力的ophthalodynamometer压缩。在43名婴儿中进行了60次检查-13名足月和11名早产儿健康对照受试者，10名颅内体积增加，9名疑似颅内顺应性异常但颅内体积未增加。阻力指数（RI）和角度校正的时间平均血流速度（TAV）进行了比较，在三个不同的pressure.Results：基线RI值在健康足月婴儿显着低于健康早产儿和婴儿异常的顺应性（P <0.05）。健康早产儿和异常依从性婴儿的值无明显差异（P > 0.5）。RI和TAV在健康婴儿中均无显著变化，但在颅顺应性异常的婴儿中，两者均随压迫而显著变化。结论：该方法可能比单独测量大脑前动脉RI更有用，以评估颅顺应性改变的婴儿。
PURPOSE: To test graded fontanelle compression during Doppler ultrasound (US) scanning to identify and monitor infants with altered cranial compliance.MATERIALS AND METHODS: An ophthalmodynamometer exerted pressure on the anterior fontanelle during Doppler US scanning of the middle cerebral artery. Sixty examinations were performed in 43 infants-13 full-term and 11 premature healthy control subjects, 10 with increased intracranial volume, and nine with suspected abnormal cranial compliance but without increased intracranial volume. Resistive index (RI) and angle-corrected time-averaged mean velocities (TAV) of blood flow were compared at three different pressures.RESULTS: Baseline RI values in healthy full-term infants were significantly lower than in healthy premature infants and infants with abnormal compliance (P < .05). Values for healthy premature infants and infants with abnormal compliance were indistinguishable (P > .5). Neither RI nor TAV changed significantly in healthy infants, but both changed significantly with compression in infants with abnormal cranial compliance.CONCLUSION: This procedure may be more useful than measurement of RI of the anterior cerebral artery alone to evaluate infants with altered cranial compliance.
