title: Sonographic depiction of changes in ventricular size associated with repeated ventricular aspirations.
abstract: Serial real-time cranial sonography was performed on 11 preterm neonates who had demonstrated progressive posthemorrhagic ventricular dilatation and were subjected to repeated ventricular aspirations. Changes in ventricular size were correlated with gestational age, birth weight, and extent and location of the intracranial hemorrhage, as well as the timing, frequency, and location of the ventricular aspirations and the average amount of cerebrospinal fluid removed. The sizes of both lateral ventricles of each neonate were measured and the occurrence of sequelae related to repeated ventricular aspiration was examined. Eleven ventricles diminished in size, eight increased, and there was no change in three. Two neonates had bleeding near the aspiration sites. It is concluded that repeated aspiration can be associated with a diminution in ventricular size in some neonates. It is recommended that alternative methods of treatment, such as serial lumbar puncture or external ventriculostomy, be attempted prior to initiating repeated ventricular aspirations.
