RESUMEN
Pereinatal asphyxia is one of the most important complications related with the process of birth and this complications affect not only the brain but also many other organs. The purpose of this cross sectional study is to compare the role of craniosonogram and CT scan of the brain to delineate the cerebral pathology in respondent of preterm and term infant and to assess the Kappa test for agreement. This study was carried out in the department of Radiology & Imaging of Mymensingh Medical College Hospital, during the period of July 2015 to June 2017. A total number of 40 neonates clinically diagnosed as perinatal asphyxia referred for Craniosonogram and Computed tomography (CT) were included in this study. The test of agreement of USG in detection of neonatal cerebral pathology was calculated. Male to female ratio was 1:1.4. More than half (55.0%) patients were preterm age. The mean birth weight was found 2.3±0.6 kg and mean age was 22.7±12.7 days. Fifty five percent respondent mothers had antenatal check up and 27% had anemia, 11% had premature rupture of membrane, 9% had multiple pregnancy and 7% patient had hypertension. Cerebral pathology was found 28 and 31 cases by Craniosonogram and CT scan respectively. Germinal matrix hemorrhage/IVH (Intra ventricular hemorrhage) found 7(17.5%) in USG and 4(10.0%) in CT scan. Hypoxic ischaemic changes with mild ventriculomegaly observed 5(12.5%) in USG and 7(17.5%) in CT scan. Hypoxic ischaemic change found 4(10.0%) in USG and 5(12.5%) in CT scan. In USG evaluation of 28 patients having cerebral pathology & 16(72.7%) had in preterm group and 12(66.7%) in term group. In CT scan of brain 31 patients with cerebral pathology & 15(37.5%) in preterm group and 16(40.0%) in term group. CT scan found cerebral pathology 77.5% (31/40) cases and USG found 70.0% (28/40), with Kappa value was 0.551, which indicates that fair agreement between USG and CT scan for detection of cerebral pathology in respondent. Craniosonogram is a useful method in all neonates specially preterm to see the CNS complication of perinatal asphyxia.
