目的评价颅脑彩超与CT诊断早产儿脑室周围白质软化的临床价值,探讨诊断早产儿脑室周围白质软化准确简便有效的方法。方法对57例接受颅脑彩超与CT检查,且诊断为脑室周围白质软化的早产儿的彩超与CT诊断结果进行分析比较。结果 57例脑室周围白质软化(PVL)早产儿,彩超首次检查均示回声增高,有40例随访到囊腔,有19例随访到囊腔消失时间,有2例未随访到囊腔出现及消失的时间,彩超复查无异常发现。50例早产儿生后10天内进行颅脑CT扫描,均示脑室周围呈明显双侧对称性低密度区,有19例1～4月进行颅脑CT扫描,其中11例呈现PVL终末期CT表现,2例呈现脑内多发软化灶,6例无异常发现。结论颅脑彩超与CT对于诊断不同的新生儿颅内病变各具特点,互有利弊,对于早产儿PVL建议颅脑彩超应作为首选检查方法,颅脑CT作为辅助检查手段,临床应合宜选择,互补应用。
Objective To evaluate the clinical value of cranial ultrasound and CT in the diagnosis of periventricular leukomalacia in preterm infants, and to explore a simple and effective method for diagnosing periventricular leukomalacia in preterm infants. Methods The color Doppler ultrasound and computed tomography (CT) findings of 57 preterm infants diagnosed as periventricular leukomalacia who underwent craniocerebral ultrasound and computed tomography were analyzed. Results 57 cases of periventricular leukomalacia (PVL) preterm children, color Doppler ultrasound showed elevated echo, 40 cases were followed up to the cyst, 19 cases were followed up to the cyst disappear time, 2 cases did not follow up to the cysts appear and disappear Of the time, no abnormal ultrasound examination found. 50 cases of premature infants within 10 days after birth, brain CT scan showed a marked bilateral ventricular symmetry of low-density area, 19 cases of 1 to 4 months of brain CT scan, 11 cases showed PVL end-stage CT findings , 2 cases showed multiple intracranial lesions, 6 cases without abnormal findings. Conclusion CT and CT are useful for the diagnosis of different neonatal intracranial lesions, which have the advantages and disadvantages of each other. For premature infants, PVL recommends craniocerebral ultrasound should be the preferred method of examination, and brain CT as an auxiliary examination, clinical should be appropriate choice, Complementary applications.
