目的探讨彩色多普勒超声在围生期窒息所致的新生儿颅脑损伤中的应用价值。方法新生儿颅脑检查中抽取可疑颅脑损伤病例50例,采用飞利浦HD-15彩色多普勒超声诊断仪经前囟冠状面、矢状面及蝶囟横切面连续扫查,并动态观察颅内病灶变化。足月儿通常选用5 MHz探头,早产儿及极低出生体重儿选用7.5 MHz探头。多普勒超声检查时,取样容积为2 mm、校正角度<30°。结果室管膜下出血18例,占36%;脑室内出血11例,占22%;脑实质内出血2例,占4%;蛛网膜下腔出血2例,占4%;脑室周围白质软化5例,占10%;脑梗死4例,占8%;脑水肿3例,占6%;丘脑和基底节损伤1例,占2%;另有2例室管膜下出血、1例脑梗死、1例脑积水未被查出。彩超诊断符合率为92%。结论彩色多普勒超声在围产期窒息所致的新生儿颅脑损伤的诊断中具有便捷、无创、实用、符合率高的特点,具有较大的临床应用价值,可为临床提供重要的参考依据。
Objective To investigate the value of color Doppler ultrasound in neonatal brain injury induced by perinatal asphyxia. Methods Fifty cases of suspected brain injury were collected from newborns with craniocerebral injury. The CT scan of the coronal, sagittal and choroidal foramina was performed by Philips HD-15 color Doppler sonography. Changes within the lesion. Full-term children usually choose 5 MHz probe, premature children and very low birth weight children use 7.5 MHz probe. Doppler ultrasound examination, the sampling volume of 2 mm, the calibration angle of <30 °. Results Subependymal hemorrhage in 18 cases, accounting for 36%; intraventricular hemorrhage in 11 cases, accounting for 22%; intraparenchymal hemorrhage in 2 cases, 4%; subarachnoid hemorrhage in 2 cases, 4%; periventricular white matter softening in 5 cases , Accounting for 10%; 4 cases of cerebral infarction, accounting for 8%; 3 cases of brain edema, accounting for 6%; 1 case of thalamus and basal ganglia injury, accounting for 2%; another 2 cases of subependymal hemorrhage, One case of hydrocephalus was not detected. Color Doppler ultrasound in line with the rate of 92%. Conclusions Color Doppler ultrasound in the diagnosis of neonatal brain injury caused by perinatal asphyxia is convenient, noninvasive, practical, with high coincidence rate, has great clinical value, and can provide important reference for clinical in accordance with.
