BACKGROUND: Intracranial hemorrhage is a severe cranial disease in the perinatal period. We aimed to explore the feasibility and accuracy of three-dimensional (3D) ultrasonography for the quantitative evaluation of neonatal intracranial hemorrhage.
METHODS: A total of 374 neonates with suspected intracranial hemorrhage from January 2017 to December 2019 were selected to be primarily screened by cranial ultrasonography and then diagnosed by cranial CT scan. The examination results were compared to analyze the feasibility and accuracy of 3D ultrasonography in quantifying blood loss.
RESULTS: CT scan showed that there were 102 cases of Papile grade I, 106 cases of grade II, 124 cases of grade III and 42 cases of grade IV. 3D ultrasonography showed that there were 108 cases of Papile grade I, 98 cases of grade II, 130 cases of grade III and 38 cases of grade IV. The diagnostic results of these two methods were not significantly different (P>0.05). The accuracies of CT scan for subventricular, intraventricular, subdural, subarachnoid and intraparenchymal hemorrhages were 47.33%, 31.24%, 94.62%, 91.73% and 91.35% respectively, and those of 3D ultrasonography were 98.74%, 96.37%, 91.51%, 90.41% and 97.64% respectively. The accuracies of 3D ultrasonography were significantly superior to those of CT scan for subependymal, intraventricular and intraparenchymal hemorrhages (P<0.05).
CONCLUSIONS: Neonatal intracranial hemorrhage can be well diagnosed by cranial ultrasonography which timely provides evidence for clinicians, thereby elevating the cure rate and reducing the mortality rate and incidence rate of sequelae. 3D ultrasonography is feasible and accurate for the quantitative evaluation of neonatal intracranial hemorrhage, thus being of great significance to prognostic determination in clinical practice.
