Abstract

Globally, approximately 15 million of preterm babies are born annual. Preterm babies are facing major health concern of poor neurodevelopment due to poor brain growth, which is a global burden. Transcranial sonography showed good accuracy to study brain growth. It is easily accessible, done at bedside, inexpensive imaging tool, and can be easily obtainable in limited resource areas comparing to MRI. However, there is still existing gap in usage of transcranial sonography during neonatal period.

AIM OF THE WORK
The aim of this study, is to assess brain growth using pons and corpus callosum measurements in preterm babies, and their relations to perinatal risk factors. Moreover, to assess relation between those measurements and resistive indices of cerebral arteries in basilar and middle cerebral artery.

PATIENTS AND METHOD
A prospective study was conducted in newborn at ≤ 32 weeks of gestation, and who didn't get major brain injury. We measured corpus callosum length, corpus callosum-fastigium length, anterior-posterior diameter of pons, pons belly size (length*width), height of cerebellar vemis, weight, and head circumference on day 1, day 7, and day 28. We collected perinatal history and clinical information while admitted.
