Image and Value Characteristics of Cranial US for Diagnosis of Meningeal Hemorrhage at Thanh Hoa Hospital of Pediatrics

Purpose: To describe the characteristics of cerebral hemorrhage images using cranial US compared with CT scan. Methods: A cross-sectional descriptive study was carried out on 36 infants under 28 days of age diagnosed and treated for meningeal hemorrhage at Thanh Hoa Hospital of Pediatrics from August 2013 to August 2015. Results: The value of cranial US compared with CT scan had the sensitivity, specificity with 68,8% and 87,5% respectively, and AUC was 0,781 . Kappa index was 0.61. Direct signs of cerebral hemorrhage on ultrasound: Hyperecoic 73.3%, inhomogenous echo 20%, hypoecoic 6.7%. Hematoma size: 40% less than 1cm, 53.3% from 1-3cm, 6.7% above 3cm. Hemorrhage position in the parenchyma 40%, subarachnoid 33,3%, mixed 26.7%. Indirect signs of hemorrhage level III, IV was 93,3%, level I, II was 6.7%. The midline shift grade I was 60%, grade was II 33.3% and grade III was 6.7%. Conclusion: Cranial US is valuable for diagnosing cerebral hemorrhage in newborns.
