Abstract
ObjectiveTo explore the related factors of subependymal hemorrhage (SEH) and cerebral hemodynamic changes.
MethodsFrom October 2012 to October 2017, 200 cases of children with subependymal hemorrhage diagnosed by ultrasound in our department of pediatrics were selected as the observation group , and a total of 150 children who were admitted to the Department of Pediatrics in the same period due to craniocerebral diseases and other serious diseases were selected as control group. The independent risk factors of the children in the observation group were analyzed, and the difference of the maximum systolic blood flow velocity (SV), the diastolic maximum flow velocity (DV), the systolic and diastolic velocity ratio (S/D), the resistance index (RI), and the pulsatile index (PI) were compared between the two groups.
ResultsNeonatal asphyxia, preterm birth, acidosis, neonatal respiratory distress syndrome (NRDS), patent ductus arteriosus and coagulation dysfunction were independent risk factors for subependymal hemorrhage. The bleeding side SV and DV of the observation group were higher than those of the control group, with statistically significant difference (P<0.001). In the observation group, the bleeding side SV and DV were higher than those of the healthy side, with statistically significant difference (P<0.001). There was no significant difference in bleeding side SV, DV, S/D, RI and PI in 110 cases of single side ependymal hemorrhage (P>0.05).
ConclusionsChildren with ependymal hemorrhage can observe the hemodynamic indexes of anterior cerebral artery (ACA) dynamically by craniocerebral ultrasound, and judge the therapeutic effect by evaluating the systolic and diastolic blood flow velocity, so as to prevent the further aggravation of subependymal hemorrhage
