Evaluation of blood flow velocity in terminal veins of both cerebral hemispheres by Doppler-sonographic measurement. The examinations were done in clinically stable, non-ventilated preterm infants between gestational weeks 29 and 36.
Terminal veins were localised by colour duplex sonography, then the maximal blood flow velocity was measured by PW Doppler. Every measurement was repeated for accuracy.
From the averaged data, percentiles were calculated for both cerebral hemispheres. A linear correlation between gestational age and maximal blood flow velocity in the terminal vein was seen. The maximal blood flow velocity increased from 3.2 cm/sec at 29 weeks to 4.6 cm/sec at 36 weeks. No difference could be seen between both cerebral hemispheres.
Percentiles could be calculated for the blood flow velocity in the terminal vein of both cerebral hemispheres. Maximal blood flow velocity increases from 29 to 36 weeks of gestational age. Serial examination during the first days of life are a feasible tool for detecting preterm infants at risk for intracerebral haemorrhage or infarction.
通过多普勒超声测量评估双侧大脑半球终末静脉的血流速度。检查在孕29至36周临床稳定、未通气的早产儿中进行。
通过彩色双功超声定位终末静脉，然后用脉冲波多普勒测量最大血流速度。每次测量均重复以确保准确性。
根据平均数据计算双侧大脑半球的百分位数。观察到胎龄与终末静脉最大血流速度之间存在线性相关性。最大血流速度从29周时的3.2厘米/秒增加到36周时的4.6厘米/秒。双侧大脑半球之间未见差异。
可计算双侧大脑半球终末静脉血流速度的百分位数。最大血流速度从孕29周增加到36周。出生后第一天进行系列检查是检测有脑出血或梗死风险的早产儿的可行方法。
