Diagnostic value of color Doppler ultrasound in early brain injury of premature infants

Abstract

Objective To investigate diagnostic value of color Doppler ultrasound in early brain injury of premature infants (BIPI). Methods The brain ultrasonography was performed on 1 200 cases of premature infants in our hospital from January 2017 to April 2018. The maturity of brain development and the characteristics of brain injury were analyzed. Results The fetal age of 1 200 cases was less than 32 weeks. Brain ultrasonography showed that the brain was immature, the echo of brain parenchyma was delicate, the sulcus was sparse, and the echo of paraventricular white matter was enhanced; the septum pellucidum, Wechsler's cavity, and central sail cavity remained. There were 108 cases of early brain injury (9.0%), including 30 cases of paraventricular leukomalacia, 34 cases of simple intracranial hemorrhage, 24 cases of ventricular hemorrhage with ventricular dilatation, 18 cases of intraventricular hemorrhage with leukomalacia, 1 case of thalamic injury, and 1 case of cerebral infarction. Conclusions Because of the immature development of various organs, premature infants are not easy to move. Brain ultrasound examination is simple, convenient, non-invasive, can be completed in the bedside, is the preferred method for screening and follow-up of early brain injury of premature infants.
