Using the Doppler technique, systolic upper limb blood pressure was found to be greater than lower limb blood pressure (mean difference 17 mmHg) in 20 normal neonates. Therefore, the finding of such a difference does not necessarily signify the presence of a pathological degree of coarctation of the aorta.
采用多普勒技术发现,20例正常新生儿的上肢收缩压高于下肢收缩压(平均差值为17mmHg)。因此,发现这种差异并不一定意味着存在病理性主动脉缩窄。
