| Abstract |
|
Serial neurosonographic examinations are routinely performed at frequent intervals during nursery couse of all preterm infants of very low-birth-weight who are admitted to the intensive care nursery of Presbyterian Medical Center from November 1,1900 to July 30, 1992.
After discharge, the following survivors who had received periodic, serial scanning by means of cranial ultrasonography were longitudinally observed in an interdisciplinary neurodevelopmental follow-up grogram to mean corrected age of 13 months. Neurodevelopmental outcome was assessed by means of Vojta's postural reaction and other neurological examinations.
The results are as follows:
1) The incidence of PV-IVH in the study was 79%.
2) According to Papile뭩 grading system of PV-IVH, grade I was 22%, grade II was 46%, grade III was 19%, and grade IV was 13%.
3) The risk factors associated with PV-IVH were birth weight, gestational age, apgar score, ventilator care, RDS, and sepsis.
4) The mortality of PV-IVH was 20% for grade I, 19% for grade II, 44% for grade III, and 67% for grade IV.
5) According to relationship between PV-IVH and neurodevelopmental outcome, in two of the four subjects with grade III PV-IVH, moderate/severe CCD was developed.
6) According to relationship betwwen PVE with cysts and nuerodevelopmental outcome, moderate/severe PVE with periventricular cysts larger than 3 mm in diameter was associated with development of severe CCD. |
